Cell-mediated lympholysis to H-2-matched target cells modified with a series of nitrophenyl compounds
TG Rehn, JK Inman and GM Shearer
The specificity of C57BL/10 cytotoxic effector cells generated by in vitro
sensitization with autologous spleen cells modified with a series of
related nitrophenyl compounds was investigated. The failure of
trinitrophenyl (TNP)-sensitized effector cells to lyse TNP-beta-
alanylglycylglycyl(AGG)-modified target cells is presented as evidence
contradicting the intimacy or dual receptor model or T-cell recognition in
its simplest form. Data are also shown indicating that sensitization with
N-(3-nitro-4-hydroxy-5-iodophenylacetyl)-AGG-modified stimulating cells
generates noncross-reacting clones of cytotoxic effector cells.
