Question

Complete each sentence about the process of B cell activation In most cases, B cells that are specific for a given epitope on an antigen cannot develop into plasma cells that secrete antibody without cytokines the collaboration of cells Antigens that elicit a response with the aid of T cells are called antigens lipopolysaccharide Interactions with the T cell cause the B cell to proliferate and differentiate into a cell, which starts producing T-dependent antibodies Thus B cells, like T cells, require two signals: antigen-BCR interaction (signal 1) and T-cell (signal 2) T-helper A few specific antigens can trigger B cells into antibody production without -cell cooperation; they are called antigens, and their stimulation of B cells is known as T-independent antigen riggering plasma Examples include bacterial and antibodies against other antibodies -Independent
