LILRB3 and cancer: As shown in Figure 2A, LILRA1, LILRA2, LILRA5, LILRB1, LILRB2, and LILRB3 are differentially expressed across several cancer types, including lung squamous cell carcinoma, lung adenocarcinoma, papillary renal cell carcinoma, and clear cell renal cell carcinoma, suggesting a potential pan-cancer role for LILR family genes.
