From: Methionine enkephalin(MENK) upregulated memory T cells in anti-influenza response
MENK increased the proportions of CD8+ T cells of mice infected with influenza virus. A Representative dot plots of CD4+ T and CD8+ T cells in BALF, lung, and LN of mice on day 10 p.i. B Panel presents the proportions of CD4+ T and CD8+ T cells. The data represent the mean ± SD of three independent experiments (each performed with n = 6 mice). ★p < 0.05, ★★p < 0.01 versus the PR8 group
