OnCo

An immune checkpoint on myeloid cells that works at the acidic pH inside tumours and is a suspected escape route after PD-1 therapy; antibodies are in early trials. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

B7-family Ig-superfamily member acting as both ligand and receptor; histidine-rich extracellular domain makes PSGL-1 binding pH-dependent; expressed at high density on neutrophils, monocytes and MDSCs.
