The major subset of dendritic cells (DC) from bovine afferent
lymph expresses the SIRP
MyD-1 antigen, but not CD11a or the antigen
recognized by mAb CC81, and potently stimulates CD4+ and
CD8+ T lymphocyte proliferation. The minor subpopulation,
that is CD11a+CC81+MyD-1-,
effectively stimulates CD4+ but not CD8+ T
lymphocyte proliferation.
CD11a+CC81+MyD-1- DC did not
induce anergy or death or secrete an inhibitory factor. However,
supernatant from cultures of CD8+ T cells with
CD11a-CC81-MyD-1+ DC
significantly enhanced proliferation of CD8+ T cells in
response to CD11a+CC81+MyD-1- DC,
an effect that was blocked by interleukin (IL)-1
, but not IL-1ß,
specific mAb. The proliferation of CD8+ T cells with
CD11a+CC81+MyD-1- DC was also
enhanced by adding IL-1
. IL-1ß slightly enhanced proliferation,
whereas IL-2, IL-6, IL-12, and IL-15 had no effect. We conclude that
the failure to stimulate CD8+ T cell proliferation results
from the lack of IL-1
synthesis by this population, which may have
important consequences in vivo.
