CD86 (T-lymphocyte activation antigen CD86, activation B7-2 antigen or CTLA-4 counter-receptor B7.2) is a molecule expressed on antigen-presenting cells that provide costimulatory signals necessary for T cell activation and survival. CD86 is the ligand for two proteins at the cell surface of T cells, CD28 antigen and CTLA-4 (cytotoxic T-lymphocyte-associated protein 4). Binding of CD86 with CTLA-4 negatively regulates T-cell activation and diminishes the immune response. Along with CD80, CD86 provides stimuli to prime T cells against antigens presented by antigen-presenting cells. CD86 is expressed on a broad spectrum of leukocytes, including B lymphocytes, T lymphocytes, macrophages, dendritic cells, and Langerhans cells, plus astrocytes. CD86 is expressed at low levels by freshly explanted peripheral B and T cells, and its expression is substantially increased by a variety of T and B cell-specific stimuli with a peak expression after 18-42 hours of culture. CD86 has also been shown to be involved in immunoglobulin class switching and triggering of mouse NK cell-mediated cytotoxicity.

Application Notes
Western Blot Analysis: A previous lot was used by an independent laboratory in WB (Esser, M.T., et al., 2001).
Immunohistochemistry Analysis: A previous lot was used by an independent laboratory in IH (Geissmann, F., et al., 2001).
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 two transcript variants encoding different isoforms. Additional transcript variants have been described, but their full-length sequences have not been determined. [provided by RefSeq].
FUNCTION: Receptor involved in the costimulatory signal essential for T-lymphocyte proliferation and interleukin-2 production, by binding CD28 or CTLA-4. May play a critical role in the early events of T-cell activation and costimulation of naive T-cells, such as deciding between immunity and anergy that is made by T-cells within 24 hours after activation. Isoform 2 interferes with the formation of CD86 clusters, and thus acts as a negative regulator of T-cell activation.
SUBUNIT STRUCTURE: Interacts with MARCH8. Interacts with human herpesvirus 8 MIR2 protein. Interacts with adenovirus subgroup B fiber proteins and acts as a receptor for these viruses.
SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
TISSUE SPECIFICITY: Expressed by activated B-lymphocytes and monocytes.
PTM: Polyubiquitinated; which is promoted by MARCH8 and results in endocytosis and lysosomal degradation.
Flow Cytometry Analysis: A 1:100-125 dilution of this antibody detected CD86 in human PBMC's.
