AB To investigate the role of donor T lymphocyte subsets in the development
of chronic graft-vs-host disease (GVHD) induced in (BALB/c x A/J)F1
(CAF1) mice by injecting BALB/c lymphoid cells, we analyzed the effect
that CD8+ cell removal from donor inoculum has on the manifestation of
the disease. Compared with age- and sex-matched CAF1 mice injected with
whole lymphocyte inoculum, CAF1 mice injected with CD8(+)-depleted
inoculum exhibited: 1) a higher incidence and exacerbation of nephritis
by immunocomplexes; 2) higher (five- to sevenfold) spontaneous IL-4
production; 3) higher frequency titer and precocity of anti-dsDNA,
anti-histone, and IgM and IgG rheumatoid factors; 4) a dramatic change
in the frequency and titer of anti-U1 small nuclear ribonucleoprotein
Abs; and 5) a markedly decreased engraftment (10- to 15-fold) on BALB/c
donor lymphocytes. In contrast, rheumatoid arthritis-like disease, a
later clinical manifestation of the GVHD in CAF1 + BALB/c model, is not
present in the CD8(+)-depleted model (CAF1 + CD8-BALB/c). Considered
together, these data suggest that CD8+ donor T lymphocytes play an
important role in the degree of chimerism, modulation of the response to
autoantigens, and clinical aspects developed in the GVHD model presented
here.
