The Interleukin (IL)-1β induced activation of the p38(MAPK)/MK2 pathway in hepatocytes is important for the control of acute phase response and regulation of liver regeneration. Many aspects of regulatory relevance of this pathway have been investigated in immune cells in the context of inflammation. However, very little is known about concentration-dependent activation kinetics and signal propagation in hepatocytes and the role of MK2. We established a mathematical model for IL-1β induced activation of the p38(MAPK)/MK2 pathway in hepatocytes that was calibrated to quantitative data on time- and IL-1β concentration-dependent phosphorylation of p38(MAPK) and MK2 in primary mouse hepatocytes...

Extending the functional integrity of renal allografts is the primary goal of transplant medicine. Development of donor-specific antibodies (DSAs) post-transplant leads to chronic active antibody-mediated rejection (cABMR) and transplant glomerulopathy (TG), resulting in the majority of graft losses in the U.S. This reduces the quality & length of life for patients and increases cost. There are no approved treatments for cABMR. Evidence suggests the pro-inflammatory cytokine interleukin 6 (IL-6) may play an important role in DSA generation and cABMR...

BACKGROUND: Mucosal and systemic immune mediators have been independently associated with HIV acquisition risk, but the relationship between compartments remains unclear. METHODS: To address this, the concentrations of 12 cytokines were compared in matched plasma and cervicovaginal lavages (CVLs) from 57 HIV-positive women before their acquisition of HIV (cases) and 50 women who remained uninfected (controls) during the CAPRISA 004 trial. RESULTS: Although genital IP-10 concentrations were significantly higher in cases, plasma IP-10 concentrations were inversely associated with HIV risk...

We investigated the effect of the major inflammatory cytokine interleukin-1beta (IL-1β) on the ventilatory response to hypoxia. The goal was to test the hypothesis that IL-1β impairs the hypoxic ventilatory response in vivo by indirectly inhibiting respiratory neurons in the brainstem via prostaglandins. Thus, IL-1β was delivered by cerebroventricular injection, and the ventilatory hypoxic response was assessed in anesthetized, spontaneously breathing rats pretreated with or without diclofenac, a nonspecific inhibitor of prostaglandin synthesis...

Interleukin-36γ (IL-36γ) is a member of novel IL-1-like proinflammatory cytokine family that are highly expressed in epithelial tissues and several myeloid-derived cell types. Little is known about the role of the IL-36 family in mucosal immunity, including lung anti-bacterial responses. We used murine models of IL-36γ deficiency to assess the contribution of IL-36γ in the lung during experimental pneumonia. Induction of IL-36γ was observed in the lung in response to Streptococcus pneumoniae (Sp) infection, and mature IL-36γ protein was secreted primarily in microparticles...

BACKGROUND: Hyperactive secretion and pathogenic effects of interleukin (IL)-17 and IgA have been detected in different arthropathies. Recent evidence has revealed that TH17 cytokines regulate mucosal IgA secretion. However, it is unknown whether and how IL-17 mediates synovial IgA production. Here we aim to investigate the connection of synovial IL-17 with IgA production in the joint. In this study we included synovial fluids (SF) from patients with rheumatoid arthritis (RA; n = 66), spondyloarthritis (SpA; n = 18) and osteoarthritis (OA; n = 36)...

BACKGROUND: Treg dysfunction or deficiency results in unopposed immune activation and autoimmunity. Interleukin-2 (IL-2) is critical for the expansion, suppressive function, and maintenance of Tregs. Although conventional T cells and NK cells respond to IL-2, Tregs are more sensitive to lower concentrations of IL-2 due to constitutive expression of CD25, the high affinity IL-2 receptor. Low-dose IL-2 therapies have shown to preferentially expand Tregs and ameliorate manifestations of graft versus host disease (Koreth et al...
