No clear differences in the changes in relative abundance during infection were observed between mouse strains for the small Il17a-expressing T cell Il17 cluster; the T cell CD4 Foxp3 cluster, likely reflecting regulatory T cells; or the CD8 T cell and NK/ILC1 clusters (Fig. 3 d; and Fig. S1, j, k, and n). The gene discussed is CD8A; the disease is infection.
