Primary versus Secondary Immune Response The primary immune response occurs the first time that the immune system comes in contact with the antigen.
Difference Between Cell Mediated and Humoral Immune Systems. The humoral immune response (HIR) is the aspect of immunity that is mediated by secreted antibodies (as opposed to cell-mediated immunity, which involves T lymphocytes) produced in the cells of the B lymphocyte lineage (B cell).B Cells (with co-stimulation) transform into plasma cells which secrete antibodies.istorically, the immune system was separated into two branches: humoral immunity, for which the protective function of immunization could be found in the humor (cell-free bodily fluid or serum) and cellular immunity, for which the protective function of immunization was associated with cells.
