Abstract

In the present study we observed that long-term cultures of tubular antigen-reactive L3T4+ T cells from immune SJL mice are able to adoptively transfer interstitial nephritis by 12 wk after i.v. injection. Lesions that develop under these conditions generally occur in the absence of anti-tubular basement membrane antibody formation. These cultured T cell lines are I-A restricted, require L3T4-associative interactions, and are tubular antigen specific, but do not share the phenotype, function, or H-2-restriction characteristics of Lyt-2+ nephritogenic effector T lymphocytes. Rather, our L3T4+ T cell lines, and phenotypically similar lymphocytes harvested from renal infiltrates, are inducers of this Lyt-2+ effector T cell repertoire. Such effector T cells, typically found in immune lymph nodes 4 to 7 days after immunization, can be induced in vitro within 5 days and will acutely transfer disease within another 5 days when placed under the kidney capsule. These findings collectively indicate that the time course for optimal effector cell differentiation and potential expression is relatively short. The immunologic inertia we previously observed between immunization or i.v. adoptive transfer and the development of cellular lesions, therefore, seems to reside in other systemic or interactional events beyond the timely formation of effector T cells.
