Flow cytometry detection of spleen lymphocyte subset and PD-1 (CD279) expression in mice. NL: normal mice; OB: obesity mice; UN: undernutrition mice. A Proportions of CD3⁺, CD3⁺CD4⁺, CD3⁺CD8⁺, CD3⁺CD279⁺, CD3⁺CD4⁺CD279⁺ and CD3⁺CD8⁺CD279⁺ T cells in spleen at the 5th week post-infection. B Proportions of CD3⁺, CD3⁺CD4⁺, CD3⁺CD8⁺, CD3⁺CD279⁺, CD3⁺CD4⁺CD279⁺ and CD3⁺CD8⁺CD279⁺ T cells in spleen at the 8th week post-infection
