Sepsis syndrome represents the leading cause of death in intensive care unit. Patients present features consistent with a decline in immune responsiveness potentially contributing to mortality. We investigated whether CD4+CD25+ regulatory T cells (Treg) participate in the induction of lymphocyte anergy after sepsis. Observational study in septic shock(More)
Sepsis, a leading cause of death worldwide, involves concomitant expression of an overzealous inflammatory response and inefficient bacterial clearance. Macrophage function is pivotal to the development of these two aspects during sepsis; however, the mechanisms underlying these changes remain unclear. Here we report that the PD-1:PD-L pathway appears to be(More)
INTRODUCTION Septic shock remains a major health care problem worldwide. Sepsis-induced immune alterations are thought to play a major role in patients' mortality and susceptibility to nosocomial infections. Programmed death-1 (PD-1) receptor system constitutes a newly described immunoregulatory pathway that negatively controls immune responses. It has(More)
Giardiasis is a ubiquitous intestinal parasitic disease that affects up to 30% of the population in developing countries [1]. It has also been reported to be the leading cause of outbreaks of waterborne disease in the USA [2]. Infection is transmitted by the ingestion of cysts, which are parasitic stages that are resistant to chlorination and can remain(More)
