Abstract
Lymph node cells derived from A.TH or A.TL mice primed with beef cytochrome c show striking patterns of reactivity when assayed in vitro for antigen-induced T cell proliferation. Whereas cells from A.TH mice respond specifically to beef cytochrome c or peptides composed of amino acids 1-65 and 81-104, cells from A.TL mice respond neither to beef cytochrome c nor to peptide 1-65, but proliferate following exposure to either peptide 81-104 or to a cytochrome c hybrid molecule in which the N-terminal peptide of beef (1-65) was substituted by a similar peptide obtained from rabbit cytochrome c. Thus, T cells from mice phenotypically unresponsive to beef cytochrome may, in fact, contain populations of lymphocytes capable of responding to a unique peptide, the response to which is totally inhibited when the same fragment is presented in the sequence of the intact protein.
