The CD28/B7 pathway provides a critical co-stimulatory signal for T cell
activation. In the present study, we cloned rat CD80 and CD86 cDNA from a
HTLV-1-transformed rat T cell line, Lewis-S1, expressing a high level of
CTLA-4-Ig binding proteins. The predicted CD80 and CD86 polypeptides were
composed of 321 and 313 amino acids respectively, and exhibited features
common to human and mouse B7 family proteins. Both CD80 and CD86 mRNAs were
abundantly detected in HTLV-1-transformed rat T cell lines but not in a
thymic lymphoma cell line. To further explore the function of rat CD80 and
CD86, we generated cDNA transfectants and anti-rat CD80 (3H5) and anti-rat
CD86 (24F) mAb. Rat CD80 or CD86 transfectants exhibited a potent
co-stimulatory activity for rat T cell proliferation, which was blocked by
3H5 and 24F mAb respectively. 3H5 or 24F immunoprecipitated a 80-90 or
90-100 kDa surface protein from Lewis-S1 cells. HTLV-1-transformed rat T
cell lines expressed high levels of both CD80 and CD86 as estimated by
staining with 3H5 and 24F, which acted co-stimulatory for allogeneic T cell
activation as estimated by blocking with 3H5 and 24F. These mAb will be
useful for investigating the pathophysiological functions of CD80 and CD86
in transplantation, autoimmune diseases and HTLV-1-associated pathologies
in the rat system.
