It is well-known that septic shock undermines immune homeostasis by inducing an initial intense systemic inflammatory response that is rapidly followed by a negative feedback of anti-inflammatory process. This secondary immunoparalysis state is characterized by decreased phagocytic cells, T cells, natural killer cells and B cells function and proinflammatory cytokine release. ⋯ Consequently, a question emerging from these findings concerns the degree to which the manipulation of T regulatory cells might improve the outcome of patients with sepsis. Preliminary studies in animal models suggest that more work is needed to understand the conditions under which such a therapy may be effective.
