Explain the 7 steps in Exogenous Antigen Processing. Should be in order List it from 1-7 . Thank you

Solution

The steps in exogenous antigen processing:

1) Endocytosis is done via recognizing \"foreign antigen\" by antigen presenting cells (APC)

2) activation of lysosomes to from phagosome

3) endosome of phagolysosome formation

4) degradation of foriegn antigen by lysoosomal, vesicualr protease enzymes

5) activity of acidic pH due to activity of hydrolytic enzymes

6) degradation of protein antigens

7) finally MHC Class II molecules are going to be undergone translation finally undergoes assembly in ER, to generate a trafficking signal to endosome
