Moreover, geometric mean fluorescent (GEO mean) intensities of these IFN-γ+ cells were significantly increased in NK1.1+NK cells, CD4+ cells, CD8+ cells, and γδT cells, indicating the average IFN-γ-producing capacities in these lymphatic cell subsets were significantly increased after HF (Figures 1H, I). Here, CD4 is linked to hydrops fetalis.
