Umbilical cord blood cytokines, immune cell subsets, and function analysis in convalescent and control groups. A series of comparisons of plasma cytokine levels between convalescent (N = 9) and control women (N = 13) (A-F). Flow cytometry staining of T cells, B cells, NK cells, Tregs, and IFN-γ expressed CD4⁺ T, CD8⁺ T, and NK cells. A series of comparisons of the proportion of total T cells, total B cells, CD4⁺ T cells, CD8⁺ T cells, NK cells, and total T + B + NK cells between convalescent (N = 4) and control women (N = 5) (G). A series of comparisons of absolute number of total T cells, total B cells, CD4⁺ T cells, CD8⁺ T cells, NK cells, and total T + B + NK cells between convalescent (N = 4) and control women (N = 5) (H). A series of comparisons of proportion of Tregs, CD45RA⁺ Tregs, and CD45RO⁺ Tregs between convalescent (N = 4) and control women (N = 5) (I). A series of comparisons of the proportion of IFN-γ expressed by CD4⁺ T cells, CD8⁺ T cells and NK cells between convalescent (N = 4) and control women (N = 5) (J). All data are presented as mean ± SEM.
