Porcine aortic endothelial cells (PAECs), unlike human endothelial cells, express a surface protein recognized by human CTLA4Ig fusion protein that costimulates human T cells through CD28. We have cloned porcine CD86 (pCD86) from an immortalized porcine endothelial cell line, PEC-A, that expresses high levels of this CTLA-4-binding protein. pCD86 mRNA is expressed in PEC-A and PAECs but not in human endothelial cells. Expression of stably transfected pCD86 in CHO cells modestly costimulates human T cell proliferation and IL-2 secretion. Expression of transiently transfected pCD86 in human umbilical vein endothelial cells strongly costimulates IL-2 production by human T cells, comparable to costimulation by PAECs. Costimulation of human T cells by pCD86 in both systems is as effective as costimulation by human CD80 or CD86, and can be blocked by human CTLA4Ig. We conclude that pCD86 contributes to the strong xenoreactivity of porcine endothelium.
