This gene encodes a type I membrane protein that is a member of the immunoglobulin superfamily. This protein is expressed by antigen-presenting cells, and it is the ligand for two proteins at the cell surface of T cells, CD28 antigen and cytotoxic T-lymphocyte-associated protein 4. Binding of this protein with CD28 antigen is a costimulatory signal for activation of the T-cell. Binding of this protein with cytotoxic T-lymphocyte-associated protein 4 negatively regulates T-cell activation and diminishes the immune response. Alternative splicing results in several transcript variants encoding different isoforms.[provided by RefSeq, May 2011]
A study in mice demonstrated that the CD86 is expressed higher in microglia compared to monocyte-derived macrophages (MDMs) after spinal cord injury [Stewart et al. DOI:10.1186/s12974-021-02161-8]. In human sepsis research, the CD86 was used as a macrophage marker in single-cell localization analysis, showing a similar expression pattern to the sepsis-associated gene S100A11 [Cao et al. DOI:10.1186/s12865-025-00778-5].
