CD4+ helper T (Th) cells are critical regulators of immune responses but their role in breast cancer is currently unknown. This work aims to characterize Th cells infiltrating invasive primary human breast tumors, analyze the influence by the tumor microenvironment and identify Th cell specific prognostic gene signatures. CD4+ T cells isolated from the tumor (TIL), axillary lymph node (LN) and blood (PB) of 10 patients were analyzed on Affymetrix U133 Plus 2.0 arrays. A confirmation set of 60 patients were studied by flow cytometry, qRT-PCR or immunohistochemistry and analyzed according to the extent of the tumor immune infiltrate. Gene expression profiles of freshly isolated TIL were also compared with TIL that had been rested overnight or with CD4+ T cells [non-stimulated (NS) or stimulated (S)] from healthy donor PB treated with tumor supernatant (SN). Comparing gene expression profiles of donor blood derived total CD4+ T cells [non-stimulated (NS)] with and without tumor supernatant (SN) treatment Total CD4+ T cells from a healthy donor blood (NS) were treated (and as control: untreated samples in biological triplicate) with SN from fresh breast tumor homogenates of 3 patients and analyzed on Affymetrix U133 Plus 2.0 arrays
