Foxp3 and IL17 expression in tumor infiltrating lymphocytes (TIL) and tumor cells - correlated or independent factors?

Tumor infiltrating lymphocytes (TIL), as a microenvironment component were studied in various epithelial tumors, with contradictory results. Recent data about regulatory T-cells (Treg) revealed new explanations for pro- and anti-tumor implications of TIL. Tregs immunoprofile was recently completed with Foxp3 expression.

Clinico-pathological correlations in fatal ischemic stroke. An immunohistochemical study of human brain penumbra.

Ischemic stroke is one of the most frequent pathologies with high invalidating potential and a leading cause of death. The brain tissue adjacent to the central necrotic core, defined as penumbra, was extensively characterized mostly by imaging techniques and in animal models. Our goal was to identify a large panel of molecules in this particular area on human brains harvested at autopsy.
