what type of cells have active t cells, cytotoxic t cells’ dnd plasma cells that die after immune response?
effector cells
which type of cells do not participate in initial immune response?
memory cells
what is the adaptive immune response occurs when b & t cells recognize a foreign antigen?
antigen presentation
what blocks or neutralizes some bacterial toxins?
neutralizing antigens
