Host epitope
The HIV-1 virus has been shown to cause diseases of the central nervous system (CNS) in humans through a molecular mimicry apparatus. HIV-1 gp41 is used to bind chemokines on the cell surface of the host so that the virion may gain entrance into the host. Astrocytes are cells of the CNS which are used to regulate the concentrations of K and neurotransmitter which enter the cerebrospinal fluid (CSF) to contribute to the blood brain barrier. A twelve amino acid sequence (Leu-Gly-Ile-Tr… WebAn epitope or antigenic determinant1 is defined as “the portion of an antigen that makes contact with a particular antibody or T cell receptor” (Macmillan Dictionary of Immunology). Epitopes recognized by T cells differ fundamentally from epitopes recognized by antibodies or …
