4-Hydroxy-3-nitrophenyl (NP) acetyl-hapten specific lymphocyte proliferation. I. Mice bearing Igh-1b allotype can cross-react with 4-hydroxy-5-iodo-3-nitrophenyl (NIP) acetyl hapten.
Hapten specific T cell proliferation was induced in several strains of mice. When lymph node T cells from 4-hydroxy-3-nitrophenyl acetyl-keyhole lympet hemocyanin (NP-KLH)-primed mice were stimulated in vitro with NP-polymer glutamic acid-lysine-phenyl alanine (NP-GL phi) or NP-ovalbumin (NP-OVA), they displayed a good level of proliferative responses. It was observed that NP-GL phi could induce NP-hapten specific proliferation even with NP-KLH lymphocytes from GL phi nonresponder strains. NP-KLH primed lymphocytes from C57BL/6 (H-2b, Igh-1b), CKB (H-2k, Igh-1b), CWB (H-2b, Igh-1b), and B10.BR (H-2k, Igh-1b) mice showed good proliferative responses to both 4-hydroxy-5-iodo-3-nitrophenyl (NIP) acetyl-GL phi and NIP-OVA antigens. However, NP-KLH primed lymphocytes from C3H/He (H-2k, Igh-1j) and C3H. SW (H-2b, Igh-1j) mice displayed poor proliferative responses to NIP-GL phi and NIP-OVA antigen. These results suggested that the gene coding for the NIP-cross-reaction might be mapped in the Ig heavy-chain linked locus.
