Human cellular immune response to measles virus polypeptides

Abstract

Measles virus polypeptides were separated by polyacrylamide gel electrophoresis and electroeluted from gel sections. The antigenicity of the polypeptides was determined by enzyme-linked immunosorbent assays. The ability of these measles virus antigens to stimulate lymphoproliferation was measured in both high- and low-responder individuals. In contrast to the low-responder lymphocytes which did not proliferate when stimulated with measles virus antigens, the high-responder lymphocytes proliferated when challenged with hemagglutinin, nucleocapsid-associated phosphoprotein, nucleocapsid protein, matrix protein, and fusion protein.
