TL;DR: The preferential expansion of a unique subset of NK cells coexpressing the activating CD94–NKG2C receptor and CD57 in CMV+ donors is demonstrated and it is proposed that CD57 might provide a marker of “memory” NK cells that have been expanded in response to infection.

TL;DR: A combination of a mature phenotype, a higher cytotoxic capacity, aHigher sensitivity to stimulation via CD16, with a decreased responsiveness to cytokines, and a decreased capacity to proliferate suggest that CD57(+) NK cells are highly mature and might be terminally differentiated.

TL;DR: A head-to-head evaluation of ten point-of-care-style lateral flow assays and two laboratory-based enzyme-linked immunosorbent assays to detect anti-SARS-CoV-2 IgM and IgG antibodies in 5-d time intervals from symptom onset underline the importance of seropositivity threshold determination and reader training for reliable LFA deployment.

TL;DR: It is found that CD3negCD56negCD16+ cells are a heterogeneous population comprised of CD7+ NK cells and CD7neg non-classical myeloid cells that may have recently engaged target cells.

TL;DR: Novel subsets of peripheral blood CD3/14/19(neg) NK cells and monocyte/dendritic cell (DC)-like cells were identified on the basis of CD7 and CD4 expression to improve the ability to study the intricacies of NK-cell subset phenotypes and functions in vivo.
