Molecular cloning of the cDNAs encoding the feline B-lymphocyte activation antigen B7-1 (CD80) and B7-2 (CD86) homologues which interact with human CTLA4-Ig

Eur J Immunogenet. 2000 Oct-Dec;27(5-6):427-30. doi: 10.1046/j.1365-2370.2000.00221.x.

Abstract

We cloned the cDNAs encoding the feline homologues of B-lymphocyte activation antigens B7-1 (CD80) and B7-2 (CD86). We expressed recombinant feline CD80 and CD86 molecules by the baculovirus expression system, and demonstrated their binding ability to human CTLA4-murine immunoglobulin fusion protein.
