Down syndrome (DS) is the most common genetic form of intellectual disability that leads in the majority of cases to development of early-onset Alzheimer-like dementia (AD). The neuropathology of DS has several common features with AD including alteration of redox homeostasis, mitochondrial deficits, and inflammation among others. Interestingly, some of the genes encoded by chromosome 21 are responsible of increased oxidative stress (OS) conditions that are further exacerbated by decreased antioxidant defense. Previous studies from our groups showed that accumulation of oxidative damage is an early event in DS neurodegeneration and that oxidative modifications of selected proteins affects the integrity …

Obesity and its associated comorbidities are of global concern. These complications are largely driven by perturbations in energy homeostasis, inflammation, and oxidative stress within metabolic tissues. Although these underlying pathways have been established, molecular mechanisms augmenting metabolic dysfunction have not been fully defined. CD47, a ubiquitously expressed cell membrane receptor, has been previously implicated in the development of inflammation and oxidative stress in a number of disease conditions. Previous work from our lab and others has confirmed that the most potent ligand of CD47, TSP1, plays a critical role in facilitating inflammation and metabolic dysfunction in diet-induced obesity. Whether these …
