Leukocyte immunoglobulin-like receptors (LIR) or CD85 have extracellular immunoglobulin domains. LIR modulates a variety of immune cells. LIR interacts with class I MHC molecules[1]. (PDB entry 1p7q). .

  • LILRA2 is an activating receptor that inhibits dendritic cell differentiation.
  • LILRA5 has a role in triggering innate immune responses.
  • LILRB1 interacts with classical and non-classical human leukocyte antigen (HLA) class I molecules[2].
  • LILRB3 is a target for treatment against acute myeloid leukaemia[3].
  • LILRB4 suppresses immunity in solid tumors[4].
