Top: Overview of the scRNA-Seq experiment; WT young (2–3 months of age), WT middle-aged (8–12 months of age), MycTg middle-aged, WT aged (15–18 months of age), and iMycTg aged-E (enlarged) (15–18 months of age) mice were infected with 10 cysts of T. gondii. T-cells were isolated from the spleen on day 12 after infection. Middle: A UMAP of the annotated CD4 and CD8 T-cell populations. Bottom: Bar plot showing the abundance of the annotated CD4 and CD8 T-cell populations.
Age-related thymic decline impairs #Tcell #immunity, increasing infection risk in the #elderly. This study shows that enhancing #thymic function in aged mice restores naïve T cells and improves immune responses, thus supporting thymic regeneration in aging @plosbiology.org 🧪 plos.io/46yMgW3
