Tumor-infiltrating B cells and T cells
We recently reported a novel cooperative relationship between tumor-infiltrating B cells and CD8(+) T cells in ovarian cancer, leading to increased patient survival. Here, we discuss the mechanisms whereby B cells might enhance cellular immunity, including serving as antigen-presenting cells, organizing tertiary lymphoid structures and secreting polarizing cytokines. The enhancement of both B a...
متن کاملTumor-infiltrating B cells
B cells infiltrating into solid tumors are poorly investigated despite their described positive prognostic value. Whether this antitumor potential comes from either the antigen presentation or the antibody production capacity of B cells, or both, is unknown. Our recently published method on tumor-infiltrating B lymphocyte cloning may prove helpful in unraveling the actual relevance of these cel...
متن کاملTumor-infiltrating follicular helper T cells
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 outcom...
متن کاملTumor-infiltrating T cells--friend or foe of neoplastic cells?
During the past 20 years, there have been many reports of the presence of inflammatory and immune-cell infiltrates in various neoplasms, including colorectal cancer. Initially, these findings were thought to indicate that although the immune system can recognize autologous tumor cells, it mounts an ineffective response to them. In the 1990s, functional studies demonstrated the presence of HLA-r...
متن کاملPhenotypic and Functional Properties of Tumor-Infiltrating Regulatory T Cells
Regulatory T (Treg) cells maintain immune homeostasis by suppressing excessive immune responses. Treg cells induce tolerance against self- and foreign antigens, thus preventing autoimmunity, allergy, graft rejection, and fetus rejection during pregnancy. However, Treg cells also infiltrate into tumors and inhibit antitumor immune responses, thus inhibiting anticancer therapy. Depleting whole Tr...
