Contribution of ROS and metabolic status to neonatal and adult CD8+ T cell activation


The low response to infection in neonatal T cells contributes to a high incidence of morbidity and mortality. Here we evaluated the effect of the cytoplasmic and mitochondrial levels of Reactive Oxygen Species (ROS) of neonatal CD8+T cells on their low activation. This model captures the interplay between antigen recognition with ROS and metabolic status in T cell responses. This model displays alternative stable states, which corresponds to different cell fates, i.e. quiescent, activated and anergic, depending on ROS status.
