Let's suppose scientists have discovered a new disease that arises when antigen-presenting cells (APCs) are not made by the body. How do you think our immune response will be impacted?
What will be an ideal response?
Antigen-presenting cells (APCs) engulf an antigen and present part of it on the membrane in combination with one of the APCs' own glycoproteins. T cells require the presentation of the antigen for activation and clonal selection. Without the presentation of antigens by APCs, the immune process would be severely impaired. T cell clone classes provide for cell-mediated immunity and include helper T cells, cytotoxic T cells, regulatory T cells, and memory cells.
