摘要: The leukocyte immunoglobulin (Ig)-like receptors (LILRs) are constituted by five inhibitory
subpopulations (LILRB1-5) and six stimulatory subpopulations (LILRA1-6). The LILR populations
substantially reside in immune cells, especially myeloid cells, functioning as a regulator in
immunosuppressive and immunostimulatory responses, during which the nonclassical major histocompatibility
complex (MHC) class I molecules are widely involved. In addition, LILRs are also
distributed in certain tumor cells, implicated in the malignancy progression. Collectively, the suppressive
Ig-like LILRB2 is relatively well-studied to date. Herein, we summarized the whole family
of LILRs and their biologic function in various diseases upon ligation to the critical ligands, therefore
providing more information on their potential roles in these pathological processes and giving
the clinical significance of strategies targeting LILRs.
