Viral IL-6 blocks neutrophil infiltration during acute inflammation.
Pathologies arising as a consequence of human herpesvirus-8 (HHV8) infections are closely associated with the autocrine activity of a HHV8 encoded IL-6 (vIL-6), which promotes proliferation of infected cells and their resistance to apoptosis. In this present report, studies show that vIL-6 may also be important in influencing the host's immunological response to secondary infections. Using peri...
متن کاملIL-6 regulates neutrophil trafficking during acute inflammation via STAT3.
The successful resolution of inflammation is dependent upon the coordinated transition from the initial recruitment of neutrophils to a more sustained population of mononuclear cells. IL-6, which signals via the common receptor subunit gp130, represents a crucial checkpoint regulator of neutrophil trafficking during the inflammatory response by orchestrating chemokine production and leukocyte a...
متن کاملInterplay between IFN-gamma and IL-6 signaling governs neutrophil trafficking and apoptosis during acute inflammation.
Regulated recruitment and clearance of neutrophils (PMN) is the hallmark of competent host defense and resolution of inflammation. We now report that IFN-gamma controls PMN infiltration and modulates IL-6 signaling through its soluble receptor (sIL-6R) to promote their apoptosis and clearance. Induction of peritoneal inflammation in IFN-gamma-deficient (IFN-gamma-/-) mice emphasized that the in...
متن کاملIL-6 trans-signaling via STAT3 directs T cell infiltration in acute inflammation.
Interleukin (IL)-6 signaling through its soluble receptor (IL-6 transsignaling) directs transition between innate and acquired immune responses by orchestrating the chemokine-directed attraction and apoptotic clearance of leukocytes. Through analysis of mononuclear cell infiltration in WT and IL-6-deficient mice during peritoneal inflammation, we now report that IL-6 selectively governs T cell ...
متن کاملInactivation of heparan sulfate 2-O-sulfotransferase accentuates neutrophil infiltration during acute inflammation in mice.
Neutrophil recruitment and extravasation at sites of inflammation provide a mechanism for host defense. We showed previously that heparan sulfate, a type of sulfated glycosaminoglycan, facilitates neutrophil recruitment based on the reduction of neutrophil infiltration in mice in which the overall sulfation of the chains was reduced by selective inactivation of N-acetylglucosamine N-deacetylase...
