Molecular mediators of polymicrobial sepsis.
Sepsis is still a major cause of postoperative morbidity and mortality. Numerous biochemical indicators have been evaluated regarding their potential in predicting prognosis in sepsis. Generally, one must differentiate between indicators: those for preoperative risk of lethal sepsis, those for early prediction of lethal outcome and those for evaluating effectiveness of therapy. In the past, imm...
متن کاملMechanisms of polymicrobial sepsis-induced ileus.
Sepsis frequently occurs after hemorrhage, trauma, burn, or abdominal surgery and is a leading cause of morbidity and mortality in severely ill patients. We performed experiments to delineate intestinal molecular and functional motility consequences of polymicrobial sepsis in the clinically relevant cecal ligation and puncture (CLP) sepsis model. CLP was performed on male Sprague-Dawley rats. G...
متن کاملToll-like receptor 9 inhibition reduces mortality in polymicrobial sepsis
The high rate of mortality in patients with sepsis results from an inappropriately amplified systemic inflammatory response to infection. Toll-like receptors (TLRs) are important for the activation of innate immunity against microbial pathogens. We demonstrate a critical role of TLR9 in the dysregulated immune response and death associated with sepsis. Compared with wild-type (WT) mice, TLR9(-/...
متن کاملChronic Viral Infection and Exacerbates Polymicrobial Sepsis Increases Susceptibility
Patients who survive sepsis display suppressed immune functions, often manifested as an increased susceptibility to secondary infections. Recently, using a cecal-ligation and puncture (CLP) model of sepsis, we showed that sepsis induces substantial and long-lasting changes in the available naive CD8 + T cell repertoire affecting the capacity of the host to respond to newly encountered acute inf...
متن کاملAdenosine A2A receptor inactivation increases survival in polymicrobial sepsis.
The mechanisms governing the impairment of bacterial clearance and immune function in sepsis are not known. Adenosine levels are elevated during tissue hypoxia and damage associated with sepsis. Adenosine has strong immunosuppressive effects, many of which are mediated by A(2A) receptors (A(2A)R) expressed on immune cells. We examined whether A(2A)R are involved in the regulation of immune func...
