Tumor-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 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 کاملCD20+ B cells: the other tumor-infiltrating lymphocytes.
Tumor-infiltrating CD8(+) T cells are strongly associated with patient survival in a wide variety of human cancers. Less is known about tumor-infiltrating CD20(+) B cells, which often colocalize with T cells, sometimes forming organized lymphoid structures. In autoimmunity and organ transplantation, T cells and B cells collaborate to generate potent, unrelenting immune responses that can result...
متن کاملAntigen-driven oligoclonal expansion of tumor-infiltrating B cells in infiltrating ductal carcinoma of the breast.
The objective of this study was to determine whether tumor-infiltrating B cells (TIL-B) of infiltrating ductal carcinoma (IDC) of the breast represent a tumor-specific humoral immune response. Immunohistochemical analysis of three Her-2/neu-negative IDC tumors from geriatric patients showed that TIL-B cluster in structures similar to germinal centers containing CD20(+) B lymphocyte and CD3(+) T...
متن کاملTumor-infiltrating B lymphocytes as an efficient source of highly specific immunoglobulins recognizing tumor cells
BACKGROUND There is much evidence that tumor cells elicit a humoral immune response in patients. In most cases, the presence of antibodies in peripheral blood is detected only in small proportion of patients with tumors overexpressing the corresponding antigen. In the present study, we analyzed the significance of local humoral response provided by tumor-infiltrating lymphocytes in breast cance...
