Tumor-infiltrating follicular helper T cells: The new kids on the block

By analyzing CD4+ lymphocytes in human breast carcinomas, we have recently uncovered the presence of follicular helper T cells in lesions exhibiting an extensive immune infiltrate. The presence of these specialized CD4+ T cells, which localize to the germinal centers of peritumoral tertiary lymphoid structures found in extensively infiltrated neoplastic lesions, predicts improved disease outcome among breast carcinoma patients ©2013 Landes Bioscience.SCOPUS: ar.j
