Abstract

Natural killer (NK) cells are usually identified by the absence of other lineage markers, due to the lack of cell-surface-specific receptors. CD56 neg NK cells, classically identified as CD56 neg CD16+, are very scarce in the peripheral blood of healthy people but they expand in some pathological conditions. However, studies on CD56 neg NK cells had revealed different results regarding the phenotype and functionality. This could be due to, among others, the unstable expression of CD16, which hinders CD56 neg NK cells' proper identification. Hence, we aim to determine an alternative surface marker to CD16 to better identify CD56 neg NK cells. We have found that NKp80 is superior to CD16. Furthermore, we found differences between the functionality of CD56 neg NKp80+ and CD56 neg CD16+, suggesting that the effector functions of CD56 neg NK cells are not as diminished as previously thought. We proposed NKp80 as a noteworthy marker to identify and accurately re-characterize human CD56 neg NK cells.
