Humoral Immune Response - 1
•Initiation of response:
•edepends upon immune systems ability to recognize antigen by T-cell receptors on:
•UCD4+ cells
•UCD8+ cells
•edepends upon major histocompatibility complex (MHC) on antigen-presenting cells (APC).
•UB-cells
•Umacrophages
•Process of response:
•eantigen-presenting cells (APC) phagocytizes antigen and process it.  Antigen fragments then placed on surface in association with MHC class molecules for T-cell to respond.
•ethis MHC restricted T-cell response insures self-recognition
