Expression of NAC1 Restrains the Memory Formation of CD8⁺ T Cells during Viral Infection.

ABSTRACT: Nucleus accumbens-associated protein 1 (NAC1) is a transcription co-factor that has been shown to possess multiple roles in stem cell and cancer biology. However, little is known about its roles in regulation of the immune system. In the current study, we observed that expression of NAC1 impacted the survival of CD8⁺ T cells in vitro. NAC1^-/- CD8⁺ T cells displayed lower metabolism, including reduced glycolysis and oxidative phosphorylation. In vivo, compared with wild-type (WT) mice, NAC1^-/- mice produced a lower response to vaccinia virus (VACV) infection, and viral antigen (Ag)-specific CD8⁺ T cells decreased more slowly. Additionally, we observed that the NAC1^-/- mice demonstrated a stronger memory formation of viral Ag-
