E-selectin, a member of the selectin family, is believed to play an important role in mediating the initial adhesive events between leucocytes and the endothelium during inflammation. A monoclonal antibody against human E-selectin was found to cross-react with the porcine equivalent, a glycoprotein of 92,000 MW. Isolation of the cDNA for porcine E-selectin showed that it was 71% homologous with human E-selectin but had two less short consensus repeats. The porcine adhesion molecule could also support the adhesion of both porcine and human neutrophils. Expression of E-selectin on interleukin-1 alpha (IL-1 alpha)- or tumour necrosis factor-alpha (TNF-alpha)-activated porcine aortic endothelial cells in culture was prolonged, persisting for up to 48 hr. Binding studies using a chimeric molecule consisting of the lectin domain of porcine E-selectin and the epidermal growth factor (EGF) domain of human E-selectin fused to the human IgG constant region, further characterized porcine E-selectin as recognizing mainly granulocytic leucocytes and a subpopulation of lymphocytes. |
