Essential Role of Sirt2 in Type I Interferon Signaling

Project description:We provide evidence for the essential role of Sirt2 in IFN mediated signaling. Our studies demonstrate that SIRT2 controls expression of key interferon stimulated genes (ISGs) that mediate important biological functions, including anti-viral and antineoplastic responses.

Sirt2 Inhibition Reprograms T Cell Metabolism to Confer Superior Anti-Tumor Immunity

Project description:Metabolism is a key driver of T cell functions, and the switch from oxidative-phosphorylation to aerobic glycolysis is a hallmark of T cell activation. However, the mechanisms underlying the metabolic switch remain unclear. Here, we report that the Sirtuin-2 (Sirt2) deacetylase protein functions as a metabolic checkpoint that harnesses T cell effector functions and impairs anti-tumor immunity. Specifically, upregulation of Sirt2 expression in human tumor-infiltrating T lymphocytes (TILs) negatively correlates with response to Nivolumab and TIL therapy in non-small cell lung cancer. Mechanistically, Sirt2 suppresses aerobic glycolysis by deacetylating key glycolytic enzymes. Accordingly, Sirt2-deficient T cells manifest increased glycolysis, display enhanced proliferation and effector functions, and have superior anti-tumor activity. Importantly, pharmacologic inhibition of Sirt2 endows human TILs with these superior metabolic fitness and enhanced effector functions. These findings indicate Sirt2 as an actionable target for reprogramming T cell metabolism to augment a broad spectrum of cancer immunotherapies.

The deacetylase SIRT2 contributes to autoimmune disease pathogenesis by modulating IL-17A and IL-2 transcription

Project description:Aberrant expression of IL-17A together with abated IL-2 production by effector CD4+ T cells contributes to the pathogenesis of systemic lupus erythematosus (SLE). Here we report that Sirtuin 2 (SIRT2), a member of the family of NAD+-dependent histone deacetylases, suppresses IL-2 production by CD4+ T cells while it promotes their differentiation into Th17 cells. Mechanistically, we show that SIRT2 is responsible for the deacetylation of p70S6K and the activation of the mTORC1/HIF-1α/RORγt pathway and the generation of Th17 cells differentiation. Additionally, SIRT2 is responsible for the deacetylation of c-Jun and histones on the Il-2 gene, resulting in decreased IL-2 production. We found that the transcription factor inducible cAMP early repressor (ICER), which is overexpressed in T cells from people with SLE and lupus-prone mice, binds directly to the Sirt2 promoter and promotes its transcription. AK-7, a SIRT2 inhibitor limited the ability of adoptively transferred antigen-specific CD4+ T cells to cause autoimmune encephalomyelitis and disease in the lupus-prone MRL/lpr mice. Finally, CD4+ T cells from SLE patients exhibited increased expression of SIRT2, and pharmacological inhibition of SIRT2 in primary CD4+ T cells from patients with SLE attenuated their ability to differentiate into Th17 cells and promoted IL-2–producing T cells. Collectively, these results suggest that SIRT2-mediated deacetylation is essential for the aberrant expression of IL-17A and IL-2 and that SIRT2 may be a promising molecular target for new therapies for SLE.

Sirt2 inhibition reprograms T cell metabolism for optimal anti-tumor immunity: Sirt2 Interacting Proteins

Project description:Growing evidence indicates that metabolism is a key driver of T cell functions. A switch from oxidative phosphorylation to aerobic glycolysis is a hallmark of T cell activation and is required to meet metabolic demands of proliferation and effector functions. However, the mechanisms underlying the metabolic switch in T cells remain unclear. Here, we identify Sirt2 as a crucial immune checkpoint coordinating metabolic and functional fitness of T cells. Sirt2 is induced upon T cell activation and increases in late maturation stages. Sirt2 negatively regulates glycolysis by targeting key glycolytic enzymes. Remarkably, Sirt2 knockout T cells exhibit profound upregulation of aerobic glycolysis with enhanced proliferation and effector function and thus effectively reject tumor challenge in vivo. Furthermore, pharmacologic inhibition of Sirt2 in human tumor infiltrating lymphocytes demonstrated a similar phenotype. Taken together, our results demonstrate Sirt2 as an actionable target to reprogram T cell metabolism to augment immunotherapy.
