Interestingly, while depletion of CD8+ T cells alongside Treg depletion appeared to rescue some of the alterations induced by Treg depletion alone in lung CD4+ Tem, naïve T cells, and the ratio of Tem to naïve T cells in HF mice, this effect did not reach statistical significance (Figures 7I–K). Here, CD8A is linked to hydrops fetalis.
