B-1 cells are innate-like lymphocytes that generate natural, polyreactive antibodies with important functions in tissue homeostasis and immune defense. While B-1-cell frequencies in secondary lymphoid tissues are low, relative high frequencies are found within peritoneal and pleural cavities of mice, including both CD5(+) B-1a and CD5(-) B-1b cells. They(More)
Natural antibodies contribute to tissue homeostasis and protect against infections. They are secreted constitutively without external antigenic stimulation. The differentiation state and regulatory pathways that enable continuous natural antibody production by B-1 cells, the main cellular source in mice, remain incompletely understood. Here we demonstrate(More)
