Natural killer (NK) cells were reported to be involved in the pathogenesis of primary antiphospholipid syndrome (pAPS). Immunosuppressive receptor T-cell immunoreceptor with Ig and ITIM domains (TIGIT) and activating receptor cluster of differentiation 226 (CD226) are specifically expressed on NK cells with competitive functions. This study aims to investigate the expression diversities of CD226/TIGIT on NK subsets and their associations with NK subsets activation phenotypes and potential clinical significance, furthermore, to explore potential cause for CD226/TIGIT expression diversities in pAPS.

Methods: In total, 325 patients were enrolled in the study, including 101 experimental group patients and 224 control group patients. The experimental group was divided into CR group (n=30) and non-CR group (n=71) according to the adenosine diphosphate (ADP)-induced platelet inhibition rate in thromboelastography (TEG) (ADP-induced platelet inhibition rate of <30% was defined as CR and rate of 30%-100% was defined as non-CR).
