In the last two decades, extensive research failed to significantly improve the outcome of patients with sepsis. In part, this drawback is based on a gap in our knowledge about molecular mechanisms understanding the pathogenesis of sepsis. During sepsis, T cells are usually depleted. ⋯ Septic sera were used to study reporter gene expression containing a PPAR-responsive element. We conclude that PPARgamma plays a significant role in T cell apoptosis, contributing to lymphocyte loss in sepsis. Thus, inhibition of PPARgamma may turn out to be beneficial for patients suffering from lymphopenia during sepsis.
