General description
Programmed cell death 1 ligand 2 (UniProt Q9BQ51; also known as B7-DC, B7 dendritic cell molecule, B7-H2, Butyrophilin B7-DC, CD273, PD-1 ligand 2, PD-L2, PDCD1 ligand 2, Programmed death ligand 2) is encoded by the PDCD1LG2 (also known as B7DC, CD273, PDCD1L2, PDL2) gene (Gene ID 80380) 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-L2 is initially produced with signal peptide (a.a. 1-19) sequence, the removal of which yields the mature protein with a large extracellular (a.a. 20-220) region that contains an Ig-like V-type domain (a.a. 21-118) and an Ig-like C2-type domain (a.a. 122-203), followed by a transmembrane domain (a.a. 221-241) and a cytoplasmic tail (a.a. 242-273).
Specificity
Clone 24F.10C12 immunostained the surface of 300.19 murine pre-B lymphoma cells transfected with human PD-L2, but not the untransfected cells or cells transfected with human PD-L1 (Brown, J.A., et al. (2003). J. Immunol. 170(3):1257-1266). Reactivity toward spliced isoform 2 (PD-L2II) and isoform 3 (PD-L2III) has not been determined.
Immunogen
Epitope: Extracellular domain.
Recombinant human PD-L2.
Application
Flow Cytometry Analysis: 0.1 µg from a representative lot detected PD-L2-positive human PBMCs.
Flow Cytometry Analysis: A representative lot immunostained the surface of 300.19 murine pre-B lymphoma cells transfected with human PD-L2, but not the untransfected cells or cells transfected with human PD-L1 (Brown, J.A., et al. (2003). J. Immunol. 170(3):1257-1266).
Flow Cytometry Analysis: A representative lot was conjugated with FITC and detected a small induction of surface PD-L2 expression on human PBMCs in culture upon IFN-gamma stimulation (Brown, J.A., et al. (2003). J. Immunol. 170(3):1257-1266).
Flow Cytometry Analysis: A representative lot was conjugated with FITC and employed to detect surface PD-L2 expression on PBMC-derived dendric cells (DCs). An upregulated PD-L2 expression was seen among mature DCs (mDC) than immature DCs (iDC), the levels of PD-L2 were reduced upon pretreatment of mDC with IL-10 (Brown, J.A., et al. (2003). J. Immunol. 170(3):1257-1266).
Flow Cytometry Analysis: A representative lot was conjugated with FITC and detected surface PD-L2 expression on tonsil-derived human follicular DCs (FDCs) (Brown, J.A., et al. (2003). J. Immunol. 170(3):1257-1266).
Neutralizing Analysis: A representative lot competed against human PD-1 extracellular domain Ig fusion for the binding of exogenously expressed human PD-L2 on the surface of 300.19 murine pre-B lymphoma cells (Brown, J.A., et al. (2003). J. Immunol. 170(3):1257-1266).
Neutralizing Analysis: DP-L2 blocking on the surface of PBMC-derived dendritic cells (DCs) by clone 24F.10C12 Fab fragment increased CD4+ T cell proliferation and cytokine production in allogenic cultures with immature DCs (iDC), mature DCs (mDC), and IL-10-treated mDCs. Dual blockage of both DP-L1 (by clone 29E.2A3 Fab fragment) and DP-L2 synergized the enhancing effect (Brown, J.A., et al. (2003). J. Immunol. 170(3):1257-1266).
Immunohistsochemistry Analysis: A representative lot detected PD-L2 expression pattern in frozen human tonsil, placenta, fetal thymus and cardiac tissue sections (Brown, J.A., et al. (2003). J. Immunol. 170(3):1257-1266).
Immunocytsochemistry Analysis: A representative lot detected an upregulated PD-L2 immunoreactivity in human CD14+ monocyte-derived macrophages (MDMs) following HIV-BaL infection, but not LPS stimulation by fluorescent immunocytochemistry using paraformaldehyde-fixed MDMs (Rodríguez-García, M., et al. (2011). J. Leukoc. Biol. 89(4) 507–515).
