Type 1 (Tc1)-stimulated (ex-vivo-activated by CD3 and CD28, IL-12 and anti-IL-4 for 48 h) OVA-specific cytotoxic CD8+ T cells (OT-I mice), naive DRG neurons (Trpv1cre::CheRiff-eGFPfl/WT) and B16F10-mCherry-OVA melanoma cancer cells were cultured alone or in combination. This evidence concerns the gene CD8A and cancer.
