We found SCT treatment markedly increased CD4+ T cell, B cell, and NKT cell fractions in spleens, NKT cells in lymph nodes, as well as increased Th1 and Th17, as well as granzyme B+, perforin+, and IFN‐γ+ CD8+ effector T cell populations in the tumor‐infiltrating T cells (Figure S9D,E, Supporting Information). The gene discussed is CD8A; the disease is neoplasm.
