Summary Introduction
Introduction:
The normal cellular immunity includes the immunity of T-lymphocytes and B-lymphocytes. The antibodies and plasma cells are present in the extracellular fluid and are generally produced by the humoral immunity. In the absence of this humoral immunity, the antibodies do not produce and bind to antigens.
