Another study suggested that Treg-expressed leukocyte-associated immunoglobulin-like receptor 2 (LAIR2) can interfere with platelet activation and adhesion by blocking the binding of LAIR1 by competing ligands, inhibit the classical pathway and lectin pathway of the complement system to kill pathogens, and act as a clinical biomarker for evaluation of patients before immunotherapy, thereby predicting patient survival and tumor immune infiltration 60. The gene discussed is LAIR2; the disease is neoplasm.
