Idiotypes on major histocompatibility complex-restricted virus-immune cytotoxic T lymphocytes
UR Kees
Specificity-associated determinants could be demonstrated on major
histocompatibility complex (MHC)-restricted virus-immune cytotoxic T
lymphocytes (CTL) using antisera raised in syngeneic mice. This result
indicates that the number of clonotypes sufficiently small to allow the
detection of such idiotypic determinants. The functional properties of
three anti-idiotypic antisera were tested in blocking studies and by
idiotypic antisera plus complement. Whereas the former test did not reveal
any results obtained from binding studies, i.e., all three anti- idiotypic
antisera specifically reacted with CTL of the type used for immunization
and had no effect on syngeneic influenza-immune CTL, syngeneic alloreactive
CTL, or NDV-immune CTL of an H-2-disparate strain. These results are
discussed in terms of current models for MHC- restricted CTL responses.
