How do B cells and T cells interact?
Classic experiments suggested that antigen-specific helper T cells interact with antigen-specific B cells via an antigen ‘bridge’, the B cells binding to one determinant on an antigen molecule (the ‘hapten’), while the T cells at the same time recognize another determinant (the ‘carrier’).Click to see full answer.

Moreover, how do B and T cells work together?Your body can then produce the most effective weapons against the invaders, which may be bacteria, viruses or parasites. Other types of T-cells recognise and kill virus-infected cells directly. Some help B-cells to make antibodies, which circulate and bind to antigens. A T-cell (orange) killing a cancer cell (mauve).Subsequently, question is, how do B cells work in the immune system? B cells, also known as B lymphocytes, are a type of white blood cell of the small lymphocyte subtype. They function in the humoral immunity component of the adaptive immune system by secreting antibodies. BCRs allow the B cell to bind to a specific antigen, against which it will initiate an antibody response. Secondly, how do T cells interact with B cells to produce antibodies? Instead they help activate cytotoxic T cells and macrophages to attack infected cells, or they stimulate B cells to secrete antibodies. Helper T cells become activated by interacting with antigen-presenting cells, such as macrophages. A receptor on the surface of the helper T cell then binds to the MHC-antigen complex.Why do B cells need T cells?Helper T cells are arguably the most important cells in adaptive immunity, as they are required for almost all adaptive immune responses. They not only help activate B cells to secrete antibodies and macrophages to destroy ingested microbes, but they also help activate cytotoxic T cells to kill infected target cells.
