CD8A and infection: The inflationary CD8+ T cell response was dominated throughout the infection by cells showing an effector (TEF, CD62L−KLRG1+) and effector-memory (TEM, CD62L−KLRG1−) phenotype, which comprised ~ 80% and 10–15% of the activated inflationary CD8+ T cell population, respectively (Figure 2E and Figure S1).
