The chemokines are a large group of chemotactic cytokines that regulate leukocyte trafficking and have recently been shown to inhibit human immunodeficiency virus entry into cells. Eotaxin is C–C chemokine implicated in the recruitment eosinophils variety inflammatory disorders and, unlike all other eosinophil chemoattractants, specific. However, given number chemoattractants activities on eosinophils, it unclear whether eotaxin has an important role vivo. Furthermore, remains why there...

Abstract Although extracellular ATP is abundant at sites of inflammation, its role in activating inflammasome signalling neutrophils not well characterized. In the current study, we demonstrate that human and murine express functional cell-surface P2X 7 R, which leads to ATP-induced loss intracellular K + , NLRP3 activation IL-1β secretion. R caused a sustained increase [Ca 2+ ], indicative channel opening. there are multiple polymorphic variants found from donors but with differential...

Gasdermin-D (GSDMD) in inflammasome-activated macrophages is cleaved by caspase-1 to generate N-GSDMD fragments. then oligomerizes the plasma membrane (PM) form pores that increase permeability, leading pyroptosis and IL-1β release. In contrast, we report although required for secretion NLRP3-activated human murine neutrophils, does not localize PM or permeability pyroptosis. Instead, biochemical microscopy studies reveal neutrophils predominantly associates with azurophilic granules LC3+...

Parasitic filarial nematodes infect more than 200 million individuals worldwide, causing debilitating inflammatory diseases such as river blindness and lymphatic filariasis. Using a murine model for in which soluble extracts of were injected into the corneal stroma, we demonstrated that predominant response cornea was due to species endosymbiotic Wolbachia bacteria. In addition, induced by these bacteria dependent on expression functional Toll-like receptor 4 (TLR4) host cells.

Eotaxin is an eosinophil-selective chemokine that constitutively expressed in a variety of organs such as the intestine. Previous studies have demonstrated recruitment eosinophils during inflammation partially dependent on eotaxin, but function constitutive eotaxin homeostasis has not been examined. To elucidate biological role this molecule, we now examine tissue levels healthy states wild-type and eotaxin-deficient mice. The lamina propria jejunum mice to express mRNA, mRNA for related...

Abstract Membrane nanotubes are a recently discovered form of cellular protrusion between two or more cells whose functions include cell communication, environmental sampling, and protein transfer.
