Background
Cluster of Differentiation 80 (also CD80 and B7-1) is a protein found on activated B cells and monocytes. B7-1 provides regulatory signals for T lymphocytes as a consequence of binding to the CD28 and CTLA4 ligands of T cells. The CD80 gene has 6 exons that span approximately 32 kb of genomic DNA. The antigen presentation coactivators B7-1 and B7-2 may be important for lymphocytic infiltration and the immune response against thyroid carcinoma.
