How does antigen binding to the BCR initiate B cell activation?
Although there are a number of potential models for the first steps of B cell activation, it is still unclear how antigen binding to the BCR initiates activation. Better understanding this process may lead to the development of therapies that would be beneficial for the treatment of autoimmunity.
How do B cells respond to protein antigens?
Antibody responses to protein antigens require antigen -specific T-cell help. B cells can receive help from armed helper T cells when antigen bound by surface immunoglobulin is internalized and returned to the cell surface as peptides bound to MHC class II molecules.
What is B cell activation?
The process controlling this series of events is referred to as B cell activation. T cell–dependent (TD) activation of B cells occurs in two distinct phases. First, B cells are triggered by antigen and, second, antigen-specific B cells interact with activated T helper (Th) cells with the same antigen specificity.
Can microbial antigens activate B cells without T-cell help?
Some microbial antigens can activate B cells directly in the absence of T-cell help. The ability of B cells to respond directly to these antigens provides a rapid response to many important bacterial pathogens.
