Polymicrobial sepsis is associated with immunosuppression caused by the predominance of anti-inflammatory mediators and profound loss of lymphocytes through apoptosis. Dendritic cells (DC) are potent antigen-presenting cells and play a key role in T cell activation. We tested the hypothesis that DC are involved in sepsis-mediated immunosuppression in a(More)
The development of immunosuppression during polymicrobial sepsis is associated with the failure of dendritic cells (DC) to promote the polarization of T helper (Th) cells toward a protective Th1 type. The aim of the study was to test potential immunomodulatory approaches to restore the capacity of splenic DC to secrete interleukin (IL) 12 that represents(More)
