New experimental model for adoptive transfer of murine autoimmune orchitis.

Abstract

Previous studies demonstrated that experimental autoimmune orchitis (EAO) was produced in C3H/He mice with very high incidence by subcutaneous (s.c.) injections of viable syngeneic testicular germ cells (TC), without resorting to any adjuvants or immunopotentiators. Using this EAO model, a new and simple protocol was developed for adoptive transfer of EAO. Cell donors were C3H/He mice that received s.c. injections twice with TC alone. Spleen cells from the donors were stimulated in vitro with TC, propagated in interleukin-2 containing medium, then injected i.p. to naive recipient mice. This procedure induced severe orchitis and hypospermatogenesis with or without inflammation in epididymis and vas deferens in the recipients at high incidence. Elimination of all T cells or CD4+ T cells before the transfer produced no histopathological signs in the recipients whereas that of the CD8+ T cells or B cells had no inhibitory effect on the disease transfer, indicating that the effector cells are CD4+ T cells.
