Abstract

Purpose: To test whether CD4+ T cells proliferate in mixed cell reactions with autologous lacrimal gland (LG) acinar cells and whether these cells can autoadoptively transfer disease.

Methods: Purified acinar cells were gamma irradiated and cocultured with peripheral blood lymphocytes. Activated CD4+ T cells were sorted by fluorescence-activated cell sorting (FACS). Unfractionated activated peripheral blood lymphocytes (UF), CD4+-enriched and CD4+-depleted T cells from an autologous mixed cell reaction were injected into the donor rabbit's remaining LG. After 4 weeks, ocular examinations were performed, and the rabbits were euthanized; LGs were removed for histopathology, immunohistochemistry, and real-time reverse transcription-polymerase chain reaction studies.

Results: CD4 T cells increased in the autologous mixed cell reaction from 20% to 80%. Tear production decreased in the induced disease/UF (ID/UF) group and declined even more in the ID/CD4+-enriched group. Tear breakup times decreased and rose bengal staining increased in all groups. All LGs exhibited significant histopathology and increased messenger RNAs for tumor necrosis factor α. The ID/UF group exhibited the largest increases of CD4+ and rabbit T-lymphocyte antigen-positive cells. The ID/CD4+-enriched group contained fewer infiltrating CD4 cells but more eosinophils, severely altered acinar morphology, and increased fibrosis. LG of the ID/CD4+-depleted group exhibited large increases of CD18, major histocompatibility complex II, and CD4+ cells. Messenger RNAs for interleukin 2, interleukin 4, and CD4+ increased in the ID/CD4+-enriched group compared with the CD4+-depleted group.

Conclusions: Autoreactive CD4+ effector cells activated ex vivo and autoadoptively transferred, caused what seems to be a distinct dacryoadenitis. The CD4+-depleted cell fraction also contained pathogenic effector cells capable of inducing disease.
