There were six DEGs related to antigen processing and presentation at 24 h after infection, including HSP70, TAP1/2, MHCI, etc. Among them, TAP plays a central role in MHC I antigen presentation, while HSP70 acts in an ATP-dependent manner and has been shown to be involved in immune stimulation, stress tolerance, and defense against bacterial invasion. The gene discussed is TAP1; the disease is infection.
