Role of B-cell and Fc receptors in the selection of T-cell epitopes

Abstract

The role of specific receptors in antigen internalization and presentation to helper T lymphocytes has been known for more than ten years. However, recent work indicates that internalization may not always be sufficient for antigen presentation. Indeed, antigen receptors such as B-cell receptors and Fc receptors may also be involved in the post-endocytic transport events that determine selectively the delivery of antigens to different endocytic compartments and thereby the presentation of different T-cell epitopes.
