Assessing the surface expression of several markers on the CD56dim subset to better characterize this NK cell population, PSP-VC had a higher frequency of the natural cytotoxicity receptor (NCR) NKp46 on their surface than PSP-PP (p = 0.007) (Fig 3D and S5A–S5H Fig). Here, NCR1 is linked to supranuclear palsy, progressive, 1.
