Melatonin enhances the expression of CD71 and CD98 in spleen NK cells of aged mice. (A) Following melatonin treatment, flow cytometry was employed to assess the expression of CD71 in NK cell subgroups at various developmental stages. (B) Statistical graph depicting CD71 fluorescence intensity in different subgroups of spleen NK Cells. (C) Following melatonin treatment, flow cytometry was employed to analyze the expression of CD98 in NK cell subgroups at various developmental stages. (D) Statistical graph illustrating CD98 fluorescence intensity in different subgroups of spleen NK Cells. The data is presented as means ± SD. n = 6. Unpaired two-tailed Student’s t-tests were conducted using Prism software. A p-value of less than 0.05 was considered statistically significant. *P < 0.05, **P < 0.01
