简要总结
Study Description:
Systemic lupus erythematosus (SLE) occurs predominantly in women and is driven by type I interferon dysregulation and neutrophil hyperresponsiveness. Neutrophils in females have reduced mitochondrial bioenergetic capacity which affects immunometabolism. Nicotinamide adenine dinucleotide (NAD)+ boosting with nicotinamide riboside blunts type 1 IFN activation in-vivo in monocytes of healthy subjects and ex-vivo in SLE subjects. These findings support the proposal of the hypothesis that NAD+ boosting by NR supplementation will modulate metabolic pathways in lupus and blunt type 1 interferon signaling. Moreover, as type 1 interferon drives endothelial dysfunction, linked to increased cardiovascular risk, the effect of NR on endothelial function will be examined.
Objectives:
Primary Objective: Evaluate the effect of NR vs. placebo on immunometabolic and inflammatory remodeling in female SLE subjects:
Exploratory Objective: Compare and characterize myeloid cell bioenergetic and immunometabolic profiles in healthy control and SLE female subjects
Endpoints:
Primary Endpoint:
The primary end point will be to assess the effect of NR on blunting type I IFN signaling by measuring monocytic secretion of IFN-beta secretion compared to baseline in response to placebo vs. NR supplemented in SLE study subjects.
Exploratory Endpoints:
Healthy control vs. SLE subjects:
- Compare type I IFN transcript profiles in monocytes and neutrophils at baseline and in response to activation.
- Assess cell bioenergetics including: 1) monocyte and neutrophil metabolic flux mass spectroscopy of 13C-glucose and 13Cglutamine analysis to investigate their metabolic fates; (iii) Mitochondrial oxygen consumption (using glucose, amino acid, and fatty acid substrates) and glycolysis rates.
SLE baseline vs. NR/placebo supplementation:
Baseline vs. 6 weeks of NR/placebo:
-Assess effect of NR on bioenergetics by measuring steady-state metabolite levels comparing changes in placebo vs. NR groups in monocytes and neutrophils.
Baseline vs. 12 weeks of NR/placebo:
- Whole blood NAD+ levels (batched and measured at the end of study enrollment period)
- Explore effects of NR on gene regulation using monocyte and neutrophils by RNA-seq and chromatin remodeling analysis.
- Determine the effect of NR vs placebo on endothelial dysfunction in SLE subjects
