Hence, BAFF preferentially drives the expansion of Th1 and Th17 pathways, consistent with previous findings that BAFF augments Th1-associated inflammatory responses. The influence of BAFF on immunoglobulin CSR occurs by TACI receptors, and impaired TACI

upregulation contributes to hyperactivity of B cells and cancer development. Thus, high BAFF levels are pointed out in various malignant diseases. In addition to BAFF receptors, autocrine and paracrine factors that promote tumour cell survival are also involved in malignant processes [4]. Autoimmune diseases are characterized by the production of autoantibodies against self-antigens via the loss of B-cell tolerance. Although the factors that promote the loss of tolerance are still not sufficiently known, BAFF clearly plays a role in autoimmune diseases. Elevated levels of BAFF were thus Deforolimus cell line shown in patients with systemic autoimmune diseases such Target Selective Inhibitor Library solubility dmso as systemic lupus erythematosus, Sjögren’s syndrome, rheumatoid

arthritis, systemic sclerosis, mixed cryoglobulinaemia, myasthenia gravis and coeliac disease as well as in organ-specific autoimmune diseases such as autoimmune hepatitis, primary biliary cirrhosis (PBC), bullous pemphigoid and localized scleroderma [7, 20–27]. In vivo administration of recombinant BAFF in mice promotes B-cell survival, expansion and differentiation, whereas BAFF transgenic mice develop hypergammaglobulinemia, proteinuria, vasculitis and lupus-like disorders. These mice had enlarged spleen, lymph nodes and glomeruli with increased circulating immune complexes, rheumatoid factors, anti-nuclear and anti-histone autoantibodies [28]. These features are also observed in patients with systemic lupus erythematosus. When BAFF transgenic mice get older, they develop a condition similar to Sjögren’s syndrome in humans characterized

by enlarged salivary glands and reduced saliva production as a consequence of acinar cell destruction [8]. In human studies, increased serum levels of BAFF were correlated with titres of anti-dsDNA, rheumatoid factor and anti-SSA/RO antibodies in patients with systemic lupus erythematosus, rheumatoid Gemcitabine price arthritis and Sjögren’s syndrome [4, 5, 20, 29]. By immunohistochemical analysis, Jonsson et al. [21] were able to detect BAFF on infiltrating cells in the salivary gland tissue from patients with Sjögren’s syndrome, and these patients also had markedly increased the levels of BAFF in their serum, suggesting the importance of BAFF signalling in disease pathogenesis. BAFF can be measured in all body fluids. In patients with rheumatoid arthritis, concentrations of BAFF in synovial fluids were much higher than in corresponding blood samples [30]. Also, BAFF levels were significantly correlated with monocyte, neutrophil and lymphocyte numbers in the synovial fluid, suggesting the local production of BAFF by the inflammatory cells.

The PKA inhibitor H89 has been shown to prevent formation of the uropod, whereas treatment with prostaglandin E2 or forskolin, which increases intracellular cAMP levels, or the cAMP analogue 8-Br-cAMP have been shown to induce uropod formation Cobimetinib in vitro in T cells [34]. We treated primary human T cells with the type I PKA-specific agonist Sp-8-Br-cAMPS prior to activation with CD3/CD28-coated beads for 20 min; however, this did not produce enhanced

distal movement of RIα or other DPC proteins (data not shown). Thus, DPC generation may also have a saturation threshold, limiting further distal transport of type I PKA.

“Chronic endometritis (CE) is a poorly investigated and probably underestimated pathology, which may cause abnormal uterine bleeding (AUB),

pain, and reproductive failures. Due to undefined symptoms and the normal presence of leukocytes in the endometrial mucosa, diagnosis may be missed. Fluid hysteroscopy is a reliable technique for diagnosing this pathology. Few data exist on the biochemical and paracrine alterations that occur in the endometrium of women diagnosed with CE. The aim of the study was to find molecular modification Cell press in endometrium related to CE. Sixteen women with hysteroscopic and histological diagnosis of CE and 10 healthy women as controls were enrolled. We compared the endometrial expression profile of 25 genes encoding proteins involved in the inflammatory response, proliferation, and apoptosis in endometrium during implantation window, using high-throughput real-time RT-PCR. In women with CE, the endometrial expression of some genes was significantly altered. In particular, IGFBP1, BCL2, and BAX were up-regulated, while IL11, CCL4, IGF1, and CASP8 were down-regulated. The altered gene endometrial expression

may explain the impaired endometrial receptivity and the finding of endometrial hyperplastic lesions in women affected by CE. “
“Although mesenchymal stromal cells (MSCs) possess the capacity to modulate immune responses, little is known about the mechanisms that underpin these processes. In this study, we show that immunosupression is mediated by activation of nuclear factor kappa B (NF-κB) in human MSCs. This pathway is activated by TNF-α that is generated following TCR stimulation of T cells. Inhibition of NF-κB through silencing of IκB kinase β or the TNF-α receptor abolishes the immunosuppressive capacity of MSCs. Our data also indicate that MSC-associated NF-κB activation primarily leads to inhibition of T-cell proliferation with little effect on expression of the activation markers CD69 and CD25.

However, during the terminal selleck chemical stages of synapse development, which is marked by close approximation of the cytolytic granules to the interface, there was clear

molecular remodeling at the IS. In YTS-721.221 conjugates, IQGAP1 and F-actin were partitioned away from the IS immediately prior to degranulation in the mature synapses (Fig. 9, compare A with B). Furthermore, this partitioning of F-actin and IQGAP1 was limited to those image planes that correlated with juxta-positioning of the cytolytic granules at the synapse (Supporting Information Fig. 1). This analysis was further extended to pNK cells. We observed striking similarities between pNK-mediated K562 killing and YTS-mediated 721.221 killing mechanism. In pNK target conjugates, IQGAP1 and F-actin levels decreased from the synapse as the granules approached the IS. Both species of proteins were clearly excluded from the IS immediately prior to final degranulation stage (Fig. 9D). The partitioning was strictly limited to the regions occupied by the granules (indicated by * in Fig. 9D and Supporting Information Fig. 2).

Hence, in NK cells both of these molecules appear to be under strict spatial and temporal regulation which is coordinated with the positioning of cytolytic granules relative to the IS. These observations highlight the mechanistic similarities between the different NK cells and further

our suggested role of IQGAP1 in NK-cell function. The rationale for undertaking the Lumacaftor molecular weight present study was to determine if IQGAP1 was required for NK effector functions. Previous studies on cytotoxic T cells indicated that IQGAP1 underwent marked distributional changes as the IS matured 10. However, neither the requirement for, nor the specific role(s) of IQGAP1 in the cytotoxic process were clear from these studies. The results of the present investigation clearly demonstrate an obligate requirement for IQGAP1 in http://www.selleck.co.jp/products/sorafenib.html NK-mediated cytotoxicity. It appears that IQGAP1 plays critical roles in multiple aspects of the events required for this process including granule reorientation and reorganization at the NKIS. IQGAP1 is a multidomain protein with the potential to interact with cytoskeletal structural elements as well as several regulators of cytoskeletal organization. Importantly, the ability of IQGAP1 to simultaneously interact, through its N- and C-terminal regions, respectively, with F-actin filaments and microtubules, provides a potential mechanism to link these cytoskeleton elements 18, 19, 30. Indeed, IQGAP1 has been implicated in a diverse range of functional and morphological changes that are dependent on cytoskeletal patterning. These include lamellipodia, adherens junctions, pseudopodia, and the formation of phagocytic cups 15, 22, 31–33.

Associations with other components were generally weak or null, except for the association of nocturia SCH727965 purchase with increased odds of hypertension (adjusted OR 2.00, 95% CI 1.27–3.14) and increased triglycerides (adjusted OR 1.64, 95% CI 1.07–2.51), and mild LUTS (AUASI 2–7) and mild incomplete emptying with a waist circumference greater than 102 cm. Kupelian et al.24 hypothesized that possible pathophysiological mechanisms to explain the relationship of voiding rather than storage symptoms with MS of BACH survey

data the influence of hyperglycemia on the parasympathetic neurons in the pelvic ganglion. Chronic hyperinsulinemia induced peripheral neuropathy resulting in increased bladder neck obstruction and reduced bladder contractility.7,25 Increased glucose levels are likely to be accompanied by hyperinsulinemia which results in an increase in insulin-like growth factor (IGF). IGF is involved in prostate growth.26 In the Baltimore Longitudinal Study on Aging (BLSA) cohort, men with elevated fasting glucose were three times more likely to have BPH than men with normal glucose levels.27 Increased fasting glucose and diabetes were also associated with the presence of LUTS in this cohort study. Other studies including

the NHANES III cohort (Rohrmann et al.28), Flint Men’s Health Study,29 and a case-control study by Neuhouser et al. (LUTS-MS30) also demonstrated the association of IGF with the risk of LUTS in men. C-reactive protein (CRP), a well-known inflammatory DAPT datasheet marker, is known to have an association

Histamine H2 receptor with cardiovascular diseases. Kupelian et al.31 assessed the relationship between CRP level and LUTS, and found a statistical significant association between CRP levels and overall LUTS among both men and women. There was a dose-response relationship between CRP levels and associated LUTS. However, Hong et al.32 studied the relationship between CRP and overactive bladder (OAB) in women without MS and found no significant correlation between CRP level and OAB symptoms. Many studies support the association of CRP and LUTS, but further research should be conducted to differentiate the significance of inflammatory process with or without MS in the development of LUTS. The prevalence of MS is increasing all over the world and Korea is not an exception. Most of the studies of MS and LUTS in Korea are risk analyses of BPH. Jang et al.33 analyzed the association of MS and BPH in 1412 men. They found that there was a significant correlation between each MS factor and prostate volume. Koo et al.34 also reported that MS is associated with prostate volume-related factors, but not with voiding dysfunction in Korean men aged 60 years or older. Among the subcategories of MS, they reported that obesity is the factor most strongly related to prostate volume. Yim et al.35 studied the correlation of prostate volume with MS and its related parameters.

2d). When we performed correlation analysis to find the relationship between this population and disease activity, it did not reach statistical significance because the number of patients with active SLE was not great enough (data not shown). However, linear regression analysis showed that the proportion of CS1-positive B cells increases linearly with increased SLEDAI score (P = 0·035, R2 = 11·4%; Fig. 2e). Because the proportion of cells can be affected by a relative lymphopenia in patients INCB024360 with SLE, we also determined the mean fluorescence intensity ratio (MFIR),

which represents the density of receptors at the single-cell level (Table 2). MFIR of CS1+ cells in total PBMCs was not significantly different between healthy controls and SLE patients. However, CD3+ CS1+ T cells up-regulated CS1 expression significantly at the single-cell level. In contrast, all NK cells down-regulated CS1 expression significantly compared to healthy controls. For analysis of B cells, we gated total B cells including both CS1-positive and CS1-negative

B cells, because percentages of CS1-positive B cells are very low in healthy controls. Despite the significant percentage increase of CS1-positive B cells, MFIR learn more shift in CS1+ cells gated within total B cells did not reach significant levels compared to healthy controls. Collectively, these data suggest that CS1-expression is regulated dynamically at the cellular and molecular levels in SLE. Recently, a number of different subsets of circulating B cells were reported in SLE, including naive B cells, memory B cells, plasma cells and plasmablasts. These cells can be identified by surface markers such as surface immunoglobulins (IgM and IgD), CD19, CD20, CD21, CD27, CD38, CD95 and human leucocyte antigen D-related (HLA-DR). Interestingly, we found that CS1 expression can also identify different subsets of SLE B cells.

Figure 3 shows that co-staining with CD19 and CS1 distinguishes three distinct subsets of B cells: CD19-middle, CS1-negative B cells; CD19-high, CS1-low B cells; and CD19-low, CS1-high B cells (best illustrated by Fig. 3d). As shown in Fig. 3a–c, healthy individuals had CD19-middle, CS1-negative B cells as a major B cell population. In contrast, most SLE patients had all three B cell populations, and all patients exhibiting a high proportion of Thalidomide CS1-positive B cells essentially had CD19-high and CD19-low B cell populations. As shown in Fig. 3e,f, some SLE patients displayed CD19-low, CS1-high B cells as their major B cell populations. Notably, as seen in Fig. 3f, one patient with active SLE (patient 1, SLEDAI = 15) displaying the highest percentage of CD19-low, CS1-high B cells had a very low number of CD19+ B cells, probably affected by lymphopenia. Next, we analysed the proportion of 2B4-expressing cells in total PBMCs, CD3+ T cells, CD56+ NK cells and CD14+ monocytes in patients with SLE and healthy controls. As shown in Fig.

Unlike MHC-restricted T cells, iNKT GW-572016 price cells recognize lipids presented by CD1d. The iNKT cells can produce various types of cytokines, rapidly and at high levels, which is why they are part

of the innate immune system. They are often the first T cells to be activated and their rapid cytokine production means that they potently transactivate other immune cells. Therefore they are an important bridge between the innate and adaptive immune system, and can orchestrate or skew an immune response depending on the array of cytokines that they produce. Importantly, we have identified a striking role for iNKT cells in regulating adipose tissue inflammation, metabolism and weight control. This review will discuss the series of findings on adipose iNKT cells that have emerged in recent years, the controversies in the metabolic phenotype of iNKT-deficient mice, and the exciting potential they may hold for manipulating

the adipose immune system in obesity. Invariant NKT cells are a specialized subset of innate T cells that are highly conserved in mammals.[4] Adaptive T cells see more recognize peptides presented by MHC molecules, but iNKT cells recognize lipids presented by CD1d molecules.[5] CD1d is a non-polymorphic MHC class I-like molecule that is expressed on antigen-presenting cells such as dendritic cells, macrophages and B cells. CD1d is also expressed on non-haematopoietic cells including hepatocytes[6] and adipocytes.[7, 8] The iNKT cells recognize their lipid ligands on CD1d through their semi-invariant T-cell receptor (TCR).[9-11] In mice, iNKT cells express TCRs comprising a Vα14-Jα18 chain paired with a limited Vβ chain repertoire (Vβ2, Vβ7, Vβ8.1,

Vβ8.2 or Vβ8.3).[12, 13] In humans, iNKT cells express Vα24-Jα18 chain paired almost exclusively with a Vβ11 chain.[14] Like iNKT cells, CD1d is highly conserved in mammals.[15] There is a large degree of functional and structural similarity between the TCRs that are expressed by human and mouse iNKT cells, to the degree that some lipids presented by human CD1d can be recognized by murine iNKT cells and vice versa. The first lipid to be identified as an antigen for iNKT cells was α-galactosylceramide (αGalCer), which remains the most potent activator of Megestrol Acetate iNKT cells. αGalCer was discovered during a screen of marine sponges for anti-cancer activity in 1997, and is derived from marine sponges, or possibly the microbes that inhabit them, and was synthetically modified to be a potent pharmacalogical activator of iNKT cells. The search for physiologically relevant lipids from pathogens or self-lipids recognized by iNKT cells is under intense investigation, and recently there have been many breakthroughs identifying endogenous and microbial lipid ligands. Endogenous lipids include isoglobotrihexosylceramide,[16] glucosylceramide,[17] lysophosphatidylcholine[18] and ether-bonded phospholipids derived from peroxisomes.

The rats were separated into four groups, each composed of 10 individual rats: (i) 10 mg/kg SLD-treated CLP group; (ii) 20 mg/kg SLD-treated CLP group; (iii) CLP group; and (iv) sham-operated control group. The groups were housed in separate cages. A CLP polymicrobial sepsis model

was applied to the rats, induced through caecal ligation and two-hole puncture. Anaesthesia was induced through the intraperitoneal administration of thiopental 25 mg/kg. The abdomen was shaved and the peritoneum was Pexidartinib chemical structure opened. Once the diaphragm exposed the abdominal organs, the caecum was isolated and ligated with a 3/0 silk ligature just distal to the ileocaecal valve. Two punctures were made with a 22-gauge needle through the caecum distal to the point of ligation, and the caecum was returned to the peritoneal cavity. The abdominal incision was then closed with a 4/0 sterile synthetic absorbable suture. The wound was bathed in 1% lidocaine solution to ensure analgesia. The sham-operated group received laparotomies,

and the rats’ caeca were manipulated but not ligated or perforated. All the animals were given 2 ml/100 g body weight of normal saline subcutaneously at the time of surgery and 6 h afterwards for fluid resuscitation. Immediately after the surgical procedure was completed, the rats in the sham-operated and the SLD-treated CLP groups received 10- or 20-mg/kg doses of SLD, which were administered with an oral gavage suspended in saline. There are many sildenafil CHIR-99021 ic50 doses for rats, varying from 0·4 mg/kg to 90 mg/kg, with different administration routes [28–33]. The reason we selected 10- and 20-mg/kg doses of oral sildenafil is that 10 mg/kg/day of sildenafil would result approximately

in the same see more plasma concentration as 50 mg in humans [34]. These doses are very common for rats, and we first aimed to determine if it is protective in CLP-induced organ damage, as well as how the dose affects protection. Therefore, we used 10- and 20-mg/kg oral doses of sildenafil, as have previous authors [35–37]. An equal volume of saline was administered to the sham-operated control group and the CLP group. The rats were deprived of food postoperatively but had free access to water for the next 16 h, until they were killed. The survival rate in CLP-induced sepsis models varies according to the size of the needle used [38]. Otero-Anton et al. reported that mortality after CLP in rats increased gradually with the size of the caecal puncture. They evaluated 0·5-cm blade incision; 13-gauge, 16-gauge and 18-gauge puncture; and four punctures with a 22-gauge needle. Mortality increased gradually with the puncture size, from 27% with a 22-gauge needle to 95% with the blade incision during a week of observation [38]. In addition, in our previous studies we observed mortality within 12–20 h after sepsis induction with a 12-gauge needle [39–42]. However, in studies performed with 21- and 22-gauge needles, mortality was not as common [38,43,44].

SIGNR1 resides in the spleen marginal zone 28 and lymph node medulla 34 captures antigens from distal infection sites via blood and lymph, respectively. Therefore, SIGNR1 in confined parts of the body in vivo plays a role as the first sensing machinery against infection. For instance,

it is known that SIGNR1 in the spleen marginal zone is involved in systemic complement activation by sensing blood-borne CPS of S. pneumoniae35. Likewise, rpMϕ are also the first interceptors for peritoneal infection and a major source of oxidative burst in peritoneal cells, as shown Fig. 4D, possibly leading to subsequent inflammatory responses in the cavity. The host innate immune system simultaneously recognizes various types of ligands on microbes via a variety of receptors on the various types selleck kinase inhibitor of cells. Recently, Dectin-2 36, 37 has been shown to also be important for host response to C. albicans. Nevertheless, our finding sheds light on the cooperation selleck screening library of different and/or similar types of PRRs in innate responses. Like the intracellular crosstalk of distinct PRR-mediated signaling pathways, PRRs also collaborate to recognize and capture

microbes and to transduce signals for enhancing cellular responses. Collectively, although the cooperative action pathway between SIGNR1 and Dectin-1 in the oxidative response is not entirely definitive, our results suggest that the anti-microbial activity/oxidative burst induction is due to efficient recognition of cell wall mannoproteins via SIGNR1 and their subsequent internalization, possibly along with the association with Dectin-1, allowing Dectin-1 to access the limited β-glucans and leading to the activation of Syk-mediated signaling. Female check details BALB/c mice were purchased from Japan SLC (Hamamatsu, Shizuoka, Japan). The mice were maintained under specific pathogen-free conditions, and used at 8–12 wk of age. All experiments were conducted according to our institutional guidelines. HEK293T cells, the mouse monocytic cell line RAW264.7 cells and RAW-transfectants (RAW-SIGNR1, RAW-control and RAW-SIGNR1Δcyto

cells) were maintained as described previously 26. Expression levels of SIGNR1 and Dectin-1 of these transfectants were analyzed with biotinylated anti-SIGNR1 clone 22D1 28 with PE-streptavidine and anti-Dectin-1 clone 2A11 (AbD Serotec, Oxford, UK) with PE-anti-rat IgG, respectively. Substitutions of glutamic acid 285 with glutamine (E285Q) in SIGNR1 were introduced by overlapping PCR. cDNA fragments of SIGNR1ΔCRD (192–325) was PCR amplified using forward primer 5′-GATCGAATTCATGAGTGACTCCACAGAAGCC-3′ in combination with reverse primer 5′-GATCCTCGAGCTACAGGCGGAAGAGTTCAGTCTTC-3′. pcDNA4/HisMax-SIGNR1 23 was used as a template, and the resulting PCR products were cloned into the EcoRI-XhoI site of pcDNA4/HisMax (Invitrogen, Carlsbad, CA). Surface expression of these mutant proteins was confirmed by flow cytometry with polyclonal anti-SIGNR1 (R&D Systems, Minneapolis, MN).

Experimentally, however, it is often difficult to discriminate direct effects of antigenic stimulation on recruitment processes from indirect effects SAR245409 research buy where a few antigen-specific T cells (‘pioneer

cells’60) are required to boost (non-specific) recruitment of T cells into the tissue. Costimulatory signals (such as those mediated by CD28) delivered to T cells, in conjunction with TCR engagement, are required to sustain T-cell division, differentiation and survival.61–63 Negative costimulators [such as cytotoxic T-lymphocyte antigen 4 (CTLA-4)] counteract these effects, thus promoting homeostatic mechanisms and preventing autoimmunity. These costimulators have been shown to regulate adhesion molecules and intracellular mediators of cytoskeletal rearrangement in vitro.64–70 In vivo, CD28-mediated signals promote the localization of T cells to target tissue following priming. A prominent feature of CD28-deficient immune responses is the inefficient localization of primed T cells to non-lymphoid antigenic sites.61,71,72 We recently reported that intact CD28 signalling is required for primed T cells to leave lymphoid tissue and migrate to antigenic

sites following priming.73 Selleckchem AZD1152HQPA TCR-transgenic T cells carrying a mutation in the cytoplasmic tail of CD28 (CD28Y170F) that abrogates phosphatidylinositol-3-kinase (PI3K) recruitment, without leading to defects in clonal expansion,74 failed to localize to target tissue following priming. The mechanism by which CD28 promotes migration of primed T cells to target tissue is unclear. CD28 does not appear to directly mediate adhesion,75 but may favour primed T-cell migration to non-lymphoid tissue by inducing integrin-mediated adhesion.73 The long-term effect of CD28-mediated signals on T-cell migration73 suggests that additional mechanisms, such as transcriptional regulation of chemokine

receptor expression,76 are likely to be involved. Despite sharing these adhesion-inducing and pro-migratory properties in vitro,77 CTLA-4-mediated signals Oxalosuccinic acid lead to effects antagonistic to those induced by CD28 on T-cell migration in vivo. CTLA-4 ligation reduced conjugate formation with cognate DCs and their retention in lymph nodes in response to antigen, suggesting that CTLA-4 engagement may limit the expansion of specific T cells by reducing their cumulative interactions with cognate DCs. In addition, tissue infiltration by a murine HY-specific H2-Kk-restricted T-cell clone was abrogated by CTLA-4 ligation,73 suggesting that CTLA-4 engagement can antagonize recruitment of primed T cells to target tissue mediated by antigen-induced signals. A number of costimulatory molecules other than CD28 and CTLA-4 have been implicated in the regulation of memory T-cell migration.

Two primer sets, universal: F_338, R_518 [49] and A. muciniphila specific [50], were used in this assay. In order to ensure an optimal specificity with the A. muciniphila genome, the sequence of the forward primer was modified as follow: F-5′-ACWCCTACGGGWGGCAGCAG-3′. The reaction mixture (20 μL) composed of 1× SYBR green PCR Master Mix (Applied Protein Tyrosine Kinase inhibitor Biosystems), 1 μL of each, either

A. muciniphila-specific primers or 16S rRNA universal primers at a final concentration of 0.25 μM, and 5 μL of template DNA adjusted to approximately equal concentration of 20 ng/μL. The PCR temperature profile was as follows: 95°C for 5 min, followed by 40 cycles of 95°C for 15 s, 60°C for 1 min. The fluorescence acquiring was set in the annealing/extension step. Subsequent to the amplification, a melting curve analysis was performed in order to distinguish putative nonspecific amplification. Serial tenfold dilutions of A. muciniphila pure culture (DSMZ 22959) genomic DNA was used to generate standard curves. A 2 cm part of ileum (starting from Midostaurin mw caecum) was partitioned lengthwise, washed gently in ice-cold PBS and one half stored in tissue homogenate lysis buffer (Ampliqon, Skovlunde, Denmark) at −80°C after immediately frozen

in liquid nitrogen, while the other half was used for flow cytometry analysis. The intestines were homogenized by using a T25 Ultraturrax homeogenizer (IKA, Staufen, Germany) and subsequently centrifuged for 15 min at 10 000 G and 4°C. The supernatant was decanted and centrifugation Resveratrol was repeated twice, the last time in a 5 μm Ultrafree MC-centrifugal filter device (Millipore, Billerica, MA, USA). Samples were kept cold during all steps. Next, the supernatant was analyzed for levels of IFN-γ, TNF-α, IL-1α, IL-1β, IL-2, IL-5, IL-6, IL-7, IL-9, IL-10, IL-12(p40), IL-15, and IL-17 by bead-based Milliplex xMAP Luminex technology (Millipore) in accordance with manufacturer’s instructions. Statistical

analysis was performed using GraphPad Prism version 5.02 (GraphPad Software, San Diego, CA, USA). Statistical significance was evaluated by the one-way ANOVA test with Tukey’s posttest when comparing three or more groups. Unpaired two-tailed t-test or Mann–Whitney test was used when comparing two groups. p values less than 0.05 were considered statistically significant.

“In peripheral lymphocytes, the transcription factors (TFs) NF-κB, NFAT, and AP-1 are the prime targets of signals that emerge from immune receptors. Upon activation, these TFs induce gene networks that orchestrate the growth, expansion, and effector function of peripheral lymphocytes.
