IL-2 complex recovers immune cells reduced by steroid in HNSCC mouse model.Immune cells from the spleen, tumor-draining lymph nodes (dLNs), and tumor-infiltrating lymphocytes (TILs) were harvested on day 45 after MOC1 inoculation. Each group was treated as shown in Fig. 6.(A) The percentage of CD4+T cells, CD8+ T cells, and Gr-1+ cells in spleens, dLNs, and TILs. (B) The percentage of CD44+ CD62L+or CD44+ CD62L− in CD4+ T cells in spleens, dLNs, and TILs.(C) The percentage of CD44+ CD62L+or CD44+ CD62L− in CD8+ T cells in spleens, dLNs, and TILs.
