Fig. 2From: CCR7loPD-1hi CXCR5+ CD4+ T cells are positively correlated with levels of IL-21 in active and transitional cystic echinococcosis patientsIncreased levels of IL-21 and IL-4 in CE patients. Serum samples were incubated with microbeads and detection reagents. The levels of IL-21 and IL-4 in CE were measured by flow cytometry analysis. The differences of IL-21 (a) and IL-4 (b) in CE were comparedBack to article page
