Abstract

Intratumoral B cells in ovarian cancers produce IgA, which binds tumor antigens and inhibit tumor growth through myeloid cell–dependent mechanisms or by neutralization of secreted factors, and by antigen-nonspecific binding to poly-Ig receptor on cancer cells leading to transcytosis, which sensitizes the cells for CTL killing.
