T cells are required for normal host defense against fungal infection, and individuals with T cell-deficiency syndromes are highly susceptible to fungal pathogens. Interleukin (IL)-17A is a proinflammatory cytokine that interconnects myeloid and lymphoid host defense. The role of murine (m) IL-17A/mIL-17A receptor (R) interactions was evaluated in a murine model of systemic candidiasis. In resp...

The innate immune functions of human airways include mucociliary clearance and antimicrobial peptide activity. Both functions may be affected by changes in epithelial ion transport. Interleukin-17A (IL-17A), which has a receptor at the basolateral membrane of airway epithelia, is a T cell cytokine that has been shown to increase mucus secretion and antimicrobial peptide production by human bron...

UNLABELLED AIMS. Interleukin-37 (IL-37) is an anti-inflammatory cytokine. This study aims to investigate the concentrations of plasma and cerebrospinal fluid (CSF) IL-37 in patients with Guillain-Barré Syndrome (GBS). METHODS The levels of plasma and CSF IL-37, IL-17A, IFN- γ , and TNF- α in 25 GBS patients and 20 healthy controls (HC) were determined by enzyme-linked immunoabsorbent assay an...

In autoimmune/lymphoproliferative syndrome (ALPS), defective Fas death receptor function causes lymphadenomegaly/splenomegaly, the expansion of T-cell receptor αβ(+) CD4/CD8 double-negative T cells, and frequent development of hematologic autoimmunity. Dianzani autoimmune lymphoproliferative disease (DALD) has a similar phenotype but lacks the expansion of double-negative T cells. This work sho...

Although interleukin-17 (IL-17) is a recently discovered cytokine associated with several autoimmune diseases, its role in the pathogenesis of chronic graft-versus-host disease (cGVHD) was not established yet. The objective of this study was to investigate the association of IL17A and IL17F genes polymorphisms and IL-17A and IL-17F levels with cGVHD. IL-17A expression was also investigated in C...

BACKGROUND AND AIM The etiology of post-inflammatory gastrointestinal (GI) motility dysfunction, after resolution of acute symptoms of inflammatory bowel diseases (IBD) and intestinal infection, is largely unknown, however, a possible involvement of T cells is suggested. METHODS Using the mouse model of T cell activation-induced enteritis, we investigated whether enhancement of smooth muscle ...

Interleukin (IL)-26 is a TH17 cytokine with known antimicrobial and pro-inflammatory functions highly expressed in tissues of TH17-mediated inflammatory diseases including psoriasis. However, the expression IL-26 respect to IL-17A its precise function context pathogenic responses are still unclear. In this study, we used flow cytometry-based fluorescent situ hybridization blood cells along sing...

Objective To quantify T helper (Th)17 cells and determine interleukin (IL)-17A levels in peripheral blood mononuclear cell (PBMC) culture and vitreous fluid from patients with type 2 diabetes mellitus (T2DM) with diabetic retinopathy (DR). Methods Th17 cell frequency and IL-17A concentrations in PBMCs from 60 patients with T2DM with DR, 30 without DR and 30 sex- and age-matched healthy individu...

BACKGROUND Sepsis-associated acute kidney injury (SA-AKI) is an independent risk factor for death in patients with sepsis, but treatment for it is limited. To improve the diagnosis and treatment of SA-AKI, we must first understand its pathogenesis. Recently, interleukin (IL)-17A has been shown to be associated with the pathogenesis of acute kidney injury and sepsis, but its role in SA-AKI remai...
