Scientific Data Images for Mouse CD160 Antibody (342705)

CD160 antibody in Mouse Splenocytes by Immunocytochemistry (ICC).

CD160 in Mouse Splenocytes.

CD160 was detected in immersion fixed CD8+mouse splenocytes using Rat Anti-Mouse CD160 Monoclonal Antibody (Catalog # MAB38991) at 25 µg/mL for 3 hours at room temperature. Cells were stained using the Northern-Lights™ 557-conjugated Anti-Rat IgG Secondary Antibody (yellow; Catalog # NL013) and counterstained with DAPI (blue). Specific staining was localized to plasma membranes and cytoplasm. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.

Background: CD160

CD160 (also Natural killer cell receptor BY55) is a 16 kDa (predicted) member of the Ig superfamily (1‑4). In mouse, it is expressed principally on nonmyeloid hematopoietic cells. These include CD3+ NK1.1 cells, CD8+ TEM and TCM T cells, CD8 alpha + IELs, NKT cells, CD8‑ gamma delta TCR T cells, and vascular endothelial cells (1, 5‑7). Mouse CD160 has been identified as a 20‑21 kDa GPI‑linked glycoprotein (4, 5). It is synthesized as a preproprotein that is 185 amino acids (aa) in length. The precursor contains a 27 aa signal sequence, a 133 aa mature molecule that shows one 98 aa V‑type Ig‑like domain (aa 28‑125), and a 25 aa prosegment that is cleaved to generate a GPI‑linkage at Ser160. Mouse GPI‑linked CD160 is known to be cleaved by phospholipase C, and this generates a 40 kDa (presumably dimeric) band in SDS‑PAGE (5). One alternative splice form for mouse CD160 is reported to show a deletion of aa 137‑180. This may generate a soluble molecule (5; GenBank Accession # NP_001156969). Mature mouse CD160 shares 63% and 88% aa identity with human and rat CD160, respectively. In mouse, CD160 is reported to bind to bind to HVEM/TNFRSF14, and both classical and non‑classical MHC Class I molecules (5, 8). MHC‑I proteins recognized by CD160 include Dd, Kb, Qa‑1b and CD1d (5). Upon engagement, the effects of CD160 ligation appear to be context dependent. When expressed on endothelial cells, CD160 binding to human HLA‑G1 initiates apoptosis, and thus impacts angiogenesis (6). When expressed on NK1.1 cells, mouse CD160 ligation alone has no effect; when combined with NK1.1 antigen stimulation, CD160 decreases NK cell IFN‑ gamma secretion. Relative to cytotoxicity, NK cell activity is positively correlated with the presence of CD160 (5).
