Abstract Cell migration depends on the ability of leukocytes to sense an external gradient chemotactic proteins produced during inflammation. These include chemokines, complement factors, and some acute phase proteins, such as serum amyloid A. Serum A chemoattracts neutrophils, monocytes, T lymphocytes via its G protein-coupled receptor formyl peptide 2. We demonstrate that A1α more potently neutrophils in vivo than vitro. In contrast CD14+ no rapid (within 2 h) induction interleukin-8/CXC...

Abstract Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening immunological disorder that characterized by systemic inflammation, widespread organ damage, and hypercytokinemia. Primary HLH caused mutations in granule-mediated cytotoxicity, whereas secondary occurs, without known genetic background, context of infections, malignancies, or autoimmune autoinflammatory disorders. Clinical manifestations both subtypes are often precipitated viral infection, predominantly with...

Several acute and chronic inflammatory diseases are driven by accumulation of activated leukocytes due to enhanced chemokine expression. In addition specific G protein-coupled receptor (GPCR)-dependent signaling, – glycosaminoglycan (GAG) interactions important for activity in vivo. Therefore, the GAG interaction has been explored as target inhibition activity. It was demonstrated that CXCL9(74-103) binds with high affinity GAGs, competed active chemokines binding thereby inhibited CXCL8-...

Abstract Systemic juvenile idiopathic arthritis (sJIA) is a childhood-onset immune disorder of unknown cause. One the concepts that disease results from an inappropriate control responses to initially harmless trigger. In current study, we investigated whether sJIA may be caused by defects in IL-10, key cytokine controlling inflammation. We used translational approach, with sJIA-like mouse model and patient samples. The relies on injection CFA IFN-γ–deficient BALB/c mice; corresponding wild...

Abstract: The need for test systems nanoparticle biocompatibility, toxicity, and inflammatory or adaptive immunological responses is paramount. Nanoparticles should be free of microbiological chemical contaminants, devoid toxicity. Nevertheless, in the absence contamination, these particles may still induce undesired effects vivo, such as enhanced autoimmunity, hypersensitivity reactions, fibrosis. Here we show that artificial specific sizes affect immune cell recruitment tested a dermal air...

Growth factors such as vascular endothelial growth factor (VEGF), fibroblast (FGF) and epidermal (EGF) are important angiogenesis-mediating factors. They exert their effects not only through respective receptor tyrosine kinases (RTKs), but they also require molecular pairing with heparan sulfate proteoglycans (HSPGs). Angiogenic signaling pathways commonly targeted in current anti-angiogenic cancer therapies have unfortunately insufficient impact on patient survival. Considering obvious role...
