Antigen processing ….
a. generates small peptides from whole antigens and loads them onto HLA molecules.
b. applies the identical cell biological mechanisms to present antigens of virally infected cells and extracellular bacteria.
c. applies the identical cell biological mechanisms for antigen recognition by CD4+ T-cells and CD8+ T-cells.
d. has the goal to directly reduce the infectious burden by destroying pathogens in professional antigen presenting cells.
The answer should be option (a) generates small peptides from whole antigens and loads them onto HLA.
- During processing Protien antigens are proteiolytically digested in the antigen presenting cells , then the antigens are loaded to HLC molecules which are present on the surface of antigen presenting cells. This process is called antigen processing.
The next step is , the Antigen presenting cell shows the antigens to the T-CELLS.This process is called antigen presentation.
Hopefully it helps if problems arises plz comment thanks.
