Abstract It is unknown whether dysregulated CSF1R himonocytes/macrophages drive the progression to diabetes and if their removal endogenous replacement with fresh macrophages resolves disease. Therefore, we hypothesize that depletion of activated CSF1R+ tissue using a monoclonal antibody against freshly differentiated will alleviate inflammation in tissues ameliorate diabetes-associated disease...

Inflammation under sterile conditions is a key event in autoimmunity and following trauma. Hyaluronan, a glycosaminoglycan released from the extracellular matrix after injury, acts as an endogenous signal of trauma and can trigger chemokine release in injured tissue. Here we investigated if NLRP3/cryopyrin, a component of the inflammasome, participates in the inflammatory response to injury or ...

Platelet-activating factor (PAF) is a significant phospholipid mediator of the immune system produced by a veriety of cells involved in inflammatory reactions in sepsis. In this experimental study, our aim was to investigate the role of PAF receptor antagonist (PAFRA) on biochemical and inflammatory disturbances in lipopolysaccharide (LPS)-treated rats. A total of 32 adult male Wistar rats were...

Recent advances have stimulated new interest in the area of crystal arthritis, as microcrystals can be considered to be endogenous "danger signals" and are potent stimulators of immune as well as non-immune cells. The best known microcrystals include urate (MSU), and calcium pyrophosphate (CPP) crystals, associated with gout and pseudogout, respectively. Acute inflammation is the hallmark of th...

Patients with primary solid malignancies frequently exhibit signs of systemic inflammation. Notably, elevated levels of neutrophils and their associated soluble mediators are regularly observed in cancer patients, and correlate with reduced survival and increased metastasis formation. Recently, we demonstrated a mechanistic link between mammary tumor-induced IL17-producing γδ T cells, systemic ...

We analyzed cytokine responses against latent and lytic Epstein-Barr virus (EBV) antigens in systemic lupus erythematosus (SLE) patients and healthy controls (HCs) to obtain an overview of the distinctive immune regulatory response in SLE patients and to expand the previously determined impaired EBV-directed T-cell response. The concentrations of 14 cytokines (IL2, IL4, IL5, IL6, IL10, IL12, IL...

Microglia rapidly mount an inflammatory response to pathogens in the central nervous system (CNS). Heparan sulfate proteoglycans (HSPGs) have been attributed various roles in inflammation. To elucidate the relevance of microglial HSPGs in a pro-inflammatory response we isolated microglia from mice overexpressing heparanase (Hpa-tg), the HS-degrading endoglucuronidase, and challenged them with l...

A non-receptor protein kinase Src plays a crucial role in fundamental cell functions such as proliferation, migration, and differentiation. While inhibition of Src is reported to contribute to chondrocyte homeostasis, its regulation at a subcellular level by chemical inhibitors and mechanical stimulation has not been fully understood. In response to inflammatory cytokines and stress to the endo...
