Researchers Uncover Functional Heterogeneity and Plasticity in Naïve CD8 T Cells

A study published in the Journal of Experimental Medicine has identified distinct subsets of naïve CD8 T cells with varying capacities to generate immune responses. The research also revealed that less potent naïve CD8 T cells can transition into more functionally capable states before infection, suggesting an unexpected degree of flexibility in the immune system.
