Find out how vesicles function in the body and what the five main types of vesicle are. We also discuss how vesicles interact with other cells and pathogens.

The latter recognize the antigen exposed on cell surfaces, in the form of peptides presented by the HLA molecule. The first part of this review details the central role played by these molecules, ...
