General description
CD80 or B7-1 is expressed in the antigen-presenting cells (APC).[1] The CD80 gene is mapped to human chromosome 3q13.33.[2]
Human secreted B7-1-Fc fusion protein, also known as CD80, with C-terminal Avitag™ . GenBank Accession No. NM_005191, a.a 35-242 expressed in a HEK293 cell expression system and enzymatically biotin-labeled using Avitag™ technology. MW = 52.5 kDa (monomer). This protein runs at a higher M.W. by SDS-PAGE due to glycosylation.
Biochem/physiol Actions
CD80 is an efficient costimulatory molecule essential for immune surveillance during carcinogenesis. It inhibits cancer progression.[3] It regulates the T cell activation to control immune response.[1] Cell stress increases the CD80 expression. Reduced expression of CD80 is observed in colon carcinoma. High levels of CD80 stimulate anti-tumor immune responses. Therefore, enhancing CD80 expression in tumors might serve as a potent approach for cancer immunotherapy.[3] Urinary CD80 is recognized as an important biomarker for idiopathic nephrotic syndrome (INS). CD80 might be involved in proteinuria, actin reorganization, and podocyte migration. Its expression in podocytes is associated with minimal change disease (MCD).[1]

Immunity, 44(5), 955-972 (2016-05-19)
Immune responses need to be controlled for optimal protective immunity and tolerance. Coinhibitory pathways in the B7-CD28 family provide critical inhibitory signals that regulate immune homeostasis and defense and protect tissue integrity. These coinhibitory signals limit the strength and duration

Urinary CD80 has emerged as potential biomarker in idiopathic nephrotic syndrome (INS). However, its cellular source remains controversial. The aim of the study was to assess whether CD80 is truly expressed by glomerular cells in INS patients during relapse and

CD80 is recognized as one of the most potent costimulatory molecules by which immune cells limit cancer progression; however, the current understanding of the regulation of its expression on human tumor cells is limited. The TP53 tumor suppressor plays a
