Question

Which is a type of presentation complex found only on macrophages, dendritic cells, and B cells?

a. Epitope

b. MHC I

c. MGC II

Answer 1

Option-c-- MHC-II

(MGC is Multinucleated Giant cell, not a surface complex)

MHC play an important role in immune responses as they show the antigens processed to the T cells

MHC I- surface complex on all nucleated cells

MHC II- surface complex or presentation complex in macrophages, dendritic and B cells. The Antigen presenting cells have MHC II in which the processed antigens are showcased to T cells for further immune response. Eventhough macrophages, dendritic cells and B cells have different cellular mechanism for processing the antigen, they showcase a part of the antigen

Epitope is the part of the antigen which is recognised by the cells of our body such as B cells, T cells, APC,etc
