abstractText | It has been demonstrated that induction of immune responses, infectious diseases and autoimmune manifestations can be associated with at least four gene loci: the major histocompatibility complex (MHC) locus; the immunoglobulin (Ig) heavy chain (Hc) locus; and the T-cell receptor (TCR) TCR-alpha or TCR-beta chain loci. In the present study, we have analysed whether T-cell responses of IE-negative C57Bl/6 (B6) mice to IE alloantigen (IE alpha transgenic B6 mice = B6.E alpha 16) or to trinitrophenylated (TNP) syngeneic spleen cells were influenced by changes in the Ig-Hc locus or the TCRa locus. Whereas the fine specificity of T-cell responses to IE alloantigen was the same in B6 mice and in Ig-Hc congenic B6.26a or TCRa congenic B6.10TCa mice, the latter strain of mice demonstrated much higher IE-specific T-cell responses against B6.E alpha 16 spleen cells than B6 or B6.26a mice. This high responsiveness was a dominant feature and associated with the TCRa locus. In addition, the TCRV alpha or V beta repertoire of the congenic strains of mice was polyclonal and very similar. The TNP-specific T-cell responses of B6 and B6.10TCa mice showed the same restricted TCRV alpha and V beta repertoire. It is concluded that in both an oligoclonal T-cell response (anti-TNP) and a polyclonal T-cell response (anti-IE), exchange of Ig-Hc or TCRa loci does not significantly influence the TCRV alpha or V beta repertoire in IE-negative C57Bl/6 mice. |
