Fig 4. ConA-induced T and NKT lymphocyte activation is reduced in iron deficiency.

(A) Intra-hepatic frequency of CD3⁺ expressing NK1.1 and CD3⁺NK1.1^- at baseline, 3 hours and 6 hours after ConA injection. (B) Intra-hepatic frequency of IFNγ production by NKT cells and T cells, defined as CD3⁺NK1.1⁺ and CD3⁺NK1.1^-, respectively, (left panel) and representative staining of IFNγ production by NKT cells (right panel) (C) Frequency of splenic CD3⁺ NK1.1^- T cells and the percentage of these ones producing IFNγ.
