Abstract

Thoracic duct lymphocytes (TDL) collected 3 days after infection of rats with Trichinella spiralis (TS) and adoptively transferred into normal, uninfected recipients, increased the numbers of both mucosal mast cells (MMC) and eosinophils (EOS) in the intestine. The CD4+ T-helper cell population was separated into two subsets (OX22+ and OX22-) using OX22 monoclonal antibody (mAb) and panning techniques. After adoptive transfer of these T-helper subsets i.v., rats were challenged with TS 24 hr later. The intestine of recipient rats was examined histologically at intervals from Day 3 to Day 21. On Day 9 after transfer, OX22+ T helpers induced a substantial mastocytosis [94 +/- 3, mean +/- SE/villus crypt unit (VCU)], whereas the OX22- T-helper subset increased resident EOS numbers (60 +/- 2/VCU) compared to the challenge control (18 +/- 1 MMC, 27 +/- 1 EOS/VCU). The time of peak eosinophilia was advanced by 3-6 days for recipients of OX22- cells and that of mast cells by 9-12 days for recipients of OX22+ cells. The recipients of OX22-, but not OX22+, cells also showed a large increase in the numbers of B cells in the spleen and mesenteric lymph node (MLN) secreting antibody against adult TS. Recipients of OX22- cells displayed an even increase in EOS throughout the villi, lamina propria (LP) and muscularis, whereas in OX22+ cell recipients mast cells were only present in the lower villus and the epithelium just above the crypt as well as the muscularis layer. Only the CD4+ OX22- cell subset conferred protection against TS in the intestine. We conclude that the OX22+ and OX22- T-helper cells exert distinctive effects in the intestine on MMC and EOS. Because protection was established in the presence of an OX22- T-helper-induced eosinophilia but without a concurrent mastocytosis, the results suggest that MMC are probably not involved in expulsion of TS to terminate the primary infection.
