Interferon gamma (IFN-γ) is a multifunctional cytokine that plays an important role in modulating almost all phases of the immune response and may be responsible for the increased valvular fibrosis and calcification in the pathogenesis of rheumatic heart disease (RHD). The aim of this study was to investigate the possible relationship between the IFN-γ +874 T/A polymorphism and the severity of valvular damage in the Turkish population. The IFN-γ genotypes were determined in 152 RHD patients and 151 healthy controls by ARMS-PCR...

Culturing 3D-expanded human placental-derived adherent stromal cells (ASCs) in the presence of tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ) transiently upregulated the secretion of numerous anti-proliferative, anti-angiogenic and pro-inflammatory cytokines. In a 3D-spheroid screening assay, conditioned medium from these induced-ASCs inhibited proliferation of cancer cell lines, including triple-negative breast cancer (TNBC) lines. In vitro co-culture studies of induced-ASCs with MDA-MB-231 human breast carcinoma cells, a model representing TNBC, supports a mechanism involving immunomodulation and angiogenesis inhibition...

Hidradenitis suppurativa (HS) is a chronic, recurrent, inflammatory disease of the apocrine sweat glands. Tumor necrosis factor-alpha (TNF-α) inhibitors are commonly used to treat HS. However, prior to initiating therapy patients must be screened for mycobacterium tuberculosis (mTB) exposure. Several mTB screening tests based on interferon gamma release assays are commercially available, but the performance of these assays in the HS population is unknown. The purpose of this study was to investigate the performance of the QuantiFERON gold in-tube assay (QFT-GIT) in a cohort of patients with Hidradenitis suppurativa (HS)...

Interferon gamma (IFNγ) is a potent inflammatory and immune cytokine. IFNγ signals via the interferon gamma receptor (IFNGR), which is constitutively bound to Janus Kinase (JAK) 1 and JAK2 via its intracellular domain. These two JAK proteins then initiate the inflammatory signaling cascade. The most potent inhibitor of IFNγ signaling is Suppressor of Cytokine Signaling 1 (SOCS1). SOCS1 negatively regulates IFNγ signaling pathway (and other pathways) by directly inhibiting JAKs. Here, we describe a protocol for the recombinant production and purification of the JAK1 kinase domain and its inhibitor SOCS1, for structural and biochemical studies...

Hepatitis C virus infection causes chronic liver disease that leads to cancer-related mortality. Presently around 30% of the HCV (infected) affected population get rid of the infection through spontaneous disease clearance. This phenomenon is conducted by a set of reported immune candidate genes. Hence, this study focuses only on these immune-response related genes with aid of network approach, where the idea is to disseminate the network for better understanding of key functional genes and their transcription control activity...

Increasing evidence suggests that T cells and glia participate in the process of neuropathic pain. However, little is known about the involvement of T cells or the interaction between glia and T cells at the molecular level. Here we investigated the phenotype of T cell infiltration into the spinal cord in inflammatory pain and explored potential crosstalk between glia and T cells. The establishment of monoarthritis produced T cell infiltration and astrocyte activation, exhibiting similar kinetics in the spinal cord...

The development of subunit vaccines against classical swine fever is a desirable goal, because it allows discrimination between vaccinated and infected animals. In this study, humoral and cellular immune response elicited in inbred BALB/c mice by immunization with a recombinant classical swine fever virus (CSFV) E2 protein fused to porcine CD154 antigen (E2CD154) was assessed. This model was used as a predictor of immune response in swine. Mice were immunized with E2CD154 emulsified in Montanide ISA50V2 or dissolved in saline on days 1 and 21...

SLAMF6, a member of the SLAM (signaling lymphocyte activation molecules) family, is a homotypic-binding immune receptor expressed on NK, T, and B lymphocytes. Phosphorylation variance between T-cell subclones prompted us to explore its role in anti-melanoma immunity. Using a 203-amino acid sequence of the human SLAMF6 (seSLAMF6) ectodomain, we found that seSLAMF6 reduced activation-induced cell death and had an anti-apoptotic effect on tumor infiltrating lymphocytes. CD8+ T cells costimulated with seSLAMF6 secreted more interferon gamma and displayed augmented cytolytic activity...

Cytomegalovirus (CMV) infection influences both short and long term outcomes in immunosuppressed organ transplant recipients. The aim of this study was to evaluate the effect of different induction immunosuppression regimens on CMV specific T cell response in patients with already established CMV immunity. In 24 seropositive living donor kidney recipients, the frequency of CMV specific T cells was determined by ELISPOT (Enzyme-Linked ImmunoSpot) assay prior and 6 months after transplantation. Recipients' peripheral blood mononuclear cells were stimulated with immediate-early (IE1) and phosphoprotein 65 (pp65) CMV-derived peptide pools and the number of cells producing interferon gamma (IFN-gamma) was assessed...

Infliximab (IFX) is effective for treatment of refractory Kawasaki disease (KD). However, the precise mechanisms and biomarkers for IFX efficacy are unknown. We tried to evaluate the effect and response to IFX therapy by measuring serum cytokine levels. Twenty-nine children with KD who had been resistant to two courses of high-dose intravenous immunoglobulin were enrolled and treated with IFX. Plasma samples were analyzed for cytokines before and after IFX administration. Serum levels of interleukin-6, granulocyte colony-stimulating factor (G-CSF), interferon-gamma-induced monokine, interferon-gamma inducible protein 10 (IP-10), monocyte chemotactic protein 1, and soluble tumor necrosis factor-alpha receptor (sTNFR) 1 and 2 were significantly elevated before IFX treatment, but promptly decreased after the administration...

Gestational diabetes mellitus (GDM) is a metabolic and low-grade inflammatory disease most commonly found in pregnant women with high body mass index and non-Caucasian ethnicities; however, not all women of high-risk groups develop GDM. We hypothesized that regulatory T cells (Tregs) might present a role in suppressing GDM development. To this end, 55 high-risk women at early pregnancy (first trimester) were recruited, and 21 of them developed GDM while the other 34 did not. Compared to those subjects who did not develop GDM (non-GDM), the patients who developed GDM presented reduced levels of Tregs and elevated levels of serum interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-alpha)...

Detection and treatment of latent tuberculosis infection (LTBI) is an essential measure for tuberculosis (TB) control in low-incidence countries. However, such strategy is limited by the low predictive ability of the diagnostic tests for the development of active TB among infected people and the long-term and toxic treatment regimens. The in vitro interferon-gamma release assays are more specific and sensitive than the tuberculin skin test (TST), and enable a better selection of cases requiring treatment. Nonetheless, their capacity to predict development of TB is still poor...

Intraepithelial lymphocytes (IELs) impart a crucial role in maintaining intestinal homeostasis, yet their role in colon cancer pathogenesis remains unknown. Here, we posited that the modulation of intestinal immune response via dietary interventions might be an implacable strategy in restraining colon carcinoma. In the above context, we studied the effect of differential ratios of fish oil (FO) and corn oil (CO) on the gut immune response in experimentally induced colon cancer. Male Wistar rats were divided into six groups: Group I obtained purified diet while Groups II and III were fed on the diet supplemented with differential ratios of FO and CO i...

Communication and drug efficacy in the immune system rely heavily on diffusion of proteins such as cytokines through the tissue matrix. Available methods to analyze diffusion in tissue require microinjection or saturating the tissue in protein, which may alter local transport properties due to damage or rapid cellular responses. Here, we developed a novel, user-friendly method - Microfluidic Integrated Optical Imaging (micro-IOI) - to quantify the effective diffusion coefficient of bioactive proteins in live tissue samples ex vivo...

Allogeneic skin transplantation is the life-saving therapy for multiple diseases, including extensive burn, large-scale trauma and certain post-surgical complications. However, acute rejection impedes clinical application of allogeneic skin transplantation. Although a lot of novel immunosuppressant drugs have been developed, there is still great need for ideal therapy with less complication and more therapeutic effects. Here, we found interferon gamma (IFN-γ) as an immunomodulatory cytokine prolonged the survival time of allografts from (8...
