BIO 106 Lecture Notes - Lecture 9: Monoclonal Antibody, Immunoglobulin D, B Cell
Document Summary
Helps protect against specific pathogens when nonspecific defenses fail. Depends on action of b and t cells (lymphocytes) Memory cells are ready to produce antibodies in future. T cells regulate immune response, produce various types. Cytotoxic (tc cells) - kills virus-infected and cancer cells. Memory (tc and th cells) - ready to kill in the future. B and t cells work hand and hand together. Apoptosis: genetically instilled cell deaths, once cells catch the infection, they are done. Igd - root of amino globins that represent receptors on b cells, signifies readiness of b cell. Derived from plasma cells originating from same b cell. Made in glassware outside the body (in vitro) Cell-mediated immunity against virus infected and cancer cells. Antigen must be presented in groove of hla (mhc) molecule. Cytotoxic t cells destroy non-self antigen-bearing cells. Helper t cells secrete cytokines that control the immune response.
