  • Title: Interaction of Mycoplasma arthritidis superantigen with human T cells.
    Author: Posnett DN, Hodtsev AS, Kabak S, Friedman SM, Cole BC, Bhardwaj N.
    Journal: Clin Infect Dis; 1993 Aug; 17 Suppl 1():S170-5. PubMed ID: 8399910.
    Abstract:
    To define the interaction site of T cell antigen receptors (TCRs) with the superantigen of Mycoplasma arthritidis (MAM), we characterized the TCRs of human MAM-reactive T cell lines and T cell clones. Most MAM-reactive T cells express the V beta 17 gene segment; however, other V beta may also be used and not all V beta 17+ TCRs are MAM-reactive. Alignment of MAM-reactive and MAM-nonreactive V beta sequences suggests that MAM does not interact with a single site encoded by a V beta segment but that several sites may be involved or that other TCR elements contribute to formation of the MAM recognition site.
