Association between BTLA polymorphisms and NSCLC risk

Importance of immune checkpoints molecules in NSCLC was proven by the introduction of blockade of these receptors in routine treatment. B and T lymphocyte attenuator (BTLA) is another immune checkpoint molecule that regulates immune response. Our previous studies showed a significant association between BTLA gene variants and susceptibility to renal cell carcinoma and chronic lymphoblastic leukemia. The aim of this study was to verify the hypothesis that BTLA polymorphic variants are associated with susceptibility to NSCLC.
