Indicate the correct order of events in the processing of phagocytized antigens.
1) CD4 coreceptor attaches to the neoantigen.
2) a transport vesicle from the ER forms carrying a Class II MHC molecule.
3) degradation of phagocytized proteins in a phagolysosome.
4) neoantigen binding to the receptor of a T_H cell.
5) fusion of ER vesicle and phagolysosome allows neoantigen formation

Question

Quizplus · Accepted Answer

The correct order starts with the degradation of phagocytized proteins in a phagolysosome (3), followed by the formation of a transport vesicle from the ER carrying a Class II MHC molecule (2). Then, the fusion of the ER vesicle and phagolysosome allows neoantigen formation (5). The neoantigen binds to the receptor of a T cell (4), and finally, the CD4 coreceptor attaches to the neoantigen (1).
