Circulating T regulatory cells migration and phenotype in glioblastoma patients: an in vitro study.

Abstract excerpt

Glioblastoma multiforme (GBM) is the most aggressive primary human brain tumor. The relatively high amount of T regulatory lymphocytes present in the tumor, contributes to the establishment of an immunosuppressive microenvironment. Samples of peripheral blood were collected from GBM patients and healthy controls and a purified population of Treg (CD4(+)/CD25(bright)) was isolated using flow cytometric cell...
