Similarly, Marrufo et al. [20] detected LLT1 expression in triple negative breast cancer (TBNC) cell lines and demonstrated that blocking LLT1-NKRP1A complex on these cells using antibodies or LLT1 gene knockdown enhanced NK cell-mediated lysis of TNBC cells. This evidence concerns the gene KLRB1 and triple-negative breast carcinoma.
