doi: 10.3389/fimmu.2026.1836862
Figure Lengend Snippet: Phenotypic and functional effects of a SLy1 knockout on splenic NK cells in dependence on p53. (A) Absolute NK cell count determined via flow cytometry in the spleen of mice of the specified genotypes. (B) Apoptotic (defined as Annexin V + ) NK cells. (C) Living (defined as 7-AAD - ) NK cells after four hours under culture conditions. (D) Expression of NKG2D, NK1.1 and NKp46 on NK cells. (E) In vitro cytotoxicity against LLC at a 25:1 effector:target ratio. Dead LLC cells were defined as 7-AAD + /Annexin V + . In all figures error bars represent standard error of the mean. ∗: p <0.05, ∗∗/##: p <0.01, ns, not significant; unpaired t-test. (F) Freshly isolated NK cells (1) attack and lyse LLC cells (2) in vitro (see arrow 3). Image was taken after four hours of incubation. Scale bar = 20 µm.
Article Snippet: 10 6 single cells were transferred into flow cytometry tubes (Sarstedt) and were washed once with cold PBS.
