General description
Programmed cell death 1 ligand 1 (UniProt Q9NZQ7; also known as B7-H1, B7 homolog 1, CD274, PD-L1, PDCD1 ligand 1, Programmed death ligand 1) is encoded by the CD274 (also known as B7H1, PDCD1L1, PDCD1LG1, PDL1) gene (Gene ID 29126) in human. PD-1 and PD-1 ligands 1&2 (PD-L1 and PD-L2) are B7:CD28 family members that regulate T cell activation and peripheral tolerance. When engaged together with the TCR, the interaction of PD-1 with its ligands delivers an inhibitory signal to T cell proliferation and cytokine production. While PD-L1 is broadly expressed in hematopoietic and nonhematopoietic cells, PD-L2 expression is highly restricted to antigen presenting cells (APCs), including dendritic cells (DCs) and macrophages. The PD-1 pathway plays a key role in the progressive loss of effector T cell responses during chronic HIV infection. Under some conditions, blockade of this pathway is able to restore many T cell functions. PD-L1 is initially produced with signal peptide (a.a. 1-18) sequence, the removal of which yields the mature protien with a large extracellular (a.a. 19-238) region that contains an Ig-like V-type domain (a.a. 19-127) and an Ig-like C2-type domain (a.a. 133-225), followed by a transmembrane domain (a.a. 239-259) and a cytoplasmic tail (a.a. 260-290).
Specificity
Clone 29E.2A3.C6 immunostained the surface of 300.19 murine pre-B lymphoma cells transfected with human PD-L1, but not the untransfected cells or cells transfected with human PD-L2 (Brown, J.A., et al. (2003). J. Immunol. 170(3):1257-1266). Reactivity toward spliced isoform 2 (PD-L1II) and isoform 3 has not been determined.

Neutralizing Analysis: Dual blockage of both DP-L1 clone 29E.2A3.C6 Fab fragment and DP-L2 by clone 24F.10C12 (Cat. No. MABC969) Fab fragment on PBMC-derived dendric cells (DCs) boosted the enhancing effect on CD4+ T-cell proliferation and cytokine release seen with DP-L2 blockage alone in allogenic cultures with immature DCs (iDC), mature DCs (mDC), and IL-10-treated mDCs (Brown, J.A., et al. (2003). J. Immunol. 170(3):1257-1266).
Immunocytochemistry Analysis: A representative lot detected an upregulated PD-L1 immunoreactivity in human CD14+ monocyte-derived macrophages (MDMs) following HIV infection or TLR4/8 stimulation (by LPS or CL097 treatment) by fluorescent immunocytochemistry using paraformaldehyde-fixed MDMs (Rodríguez-García, M., et al.
