Cardiac inflammation and innate immunity in septic shock: is there a role for toll-like receptors?
Our current understanding of the pathogenesis of sepsis suggests that bacteria as well as bacterial-derived products activate an uncontrolled network of host-derived mediators such as proinflammatory cytokines (ie, tumor necrosis factor [TNF] and interleukin [IL]-1beta), which can ultimately lead to cardiovascular collapse and death. Despite the potentially important role that TNF and IL-1beta ...
متن کاملHeat shock protein and innate immunity.
In addition to serving as molecular chaperones, heat shock proteins (HSPs) have been implicated in autoimmune diseases, antigen presentation and tumor immunity. Extensive work in the last 10 years has also suggested that HSPs such as Hsp60, Hsp70, Hsp90 and gp96, may be potent activators of the innate immune system capable of inducing the production of pro-inflammatory cytokines by the monocyte...
متن کاملProtection of innate immunity by C5aR antagonist in septic mice.
Innate immune functions are known to be compromised during sepsis, often with lethal consequences. There is also evidence in rats that sepsis is associated with excessive complement activation and generation of the potent anaphylatoxin C5a. In the presence of a cyclic peptide antagonist (C5aRa) to the C5a receptor (C5aR), the binding of murine 125I-C5a to murine neutrophils was reduced, the in ...
متن کاملHeat Shock Proteins: Stimulators of Innate and Acquired Immunity
Adjuvants were reintroduced into modern immunology as the dirty little secret of immunologists by Janeway and thus began the molecular definition of innate immunity. It is now clear that the binding of pathogen-associated molecular patterns (PAMPs) by pattern recognition receptors (PRRs) on antigen presenting cells (APCs) activates the innate immune response and provides the host with a rapid m...
متن کاملSeptic Shock
Pediatric severe sepsis and septic shock continue to be significant causes of childhood morbidity and mortality worldwide. The following review will highlight some of the controversies surrounding the consensus definitions. It will chronicle recent clinical and translational research, focusing on pediatric sepsis-specific challenges investigators face. It will also address the pathophysiology o...
