Quizplus · Accepted Answer

B cells are activated in response to a specific antigen, which can be presented by antigen-presenting cells (APCs) such as dendritic cells or macrophages. Once activated, B cells differentiate into plasma cells that secrete antibodies specific to the antigen that initiated the response. B cells do not engage in cell-mediated combat, which is the function of T cells. Kupffer cells are specialized macrophages located in the liver, but they are not the same as B cells.
