Increased adiposity has been associated with macrophage infiltration into the adipose tissue which, in turn, leads to obesity comorbidities, including type 2 diabetes. The objective of this study was to evaluate the effect of anthocyanin (ANC)-enriched fractions from blackberry-blueberry beverages on inflammation and adipogenesis in an in vitro model of inflammation mimicking the pathologic interaction between adipocytes and macrophages. Blend ANCs inhibited secretion of nitric oxide (17.5%), tumor necrosis factor-alpha (TNF-α) (89.4%), and phosphorylated-p65 nuclear factor kappa-B (52.1%) in lipopolysaccharide (LPS)-induced RAW264.7 macrophages after 24 h. Blends reduced intracellular fat accumulation (28.2%) when applied during 3T3-L1 adipocyte differentiation and inhibited isoproterenol-induced lipolysis (18.6%) of mature 3T3-L1 cells. In addition, blend ANCs restored adiponectin-blunted gene expression induced by the TNF-α treatment (18.2%) and reduced the glycerol release (15.9%) induced by LPS-induced macrophage-conditioned media (CM) in adipocytes. Furthermore, blends slightly restored the insulin-induced glucose uptake of adipocytes, blunted by the CM treatment. In conclusion, ANCs from blueberry and blackberry dealcoholized fermented beverages are potential inhibitors of inflammation-related adiposity response and sensitizers of insulin signaling in adipocytes.

Background: Obesity in midlife, body mass index (BMI) of 30 kg/m or higher, is recognized as a contributor to Alzheimer disease (AD) later in life. Adiposity in visceral tissues such as liver is associated with increased systemic inflammation and impaired cognition. In this study, we aimed to investigate the relationship between MRI‐derived Positron Density Fat Fraction (PDFF) and brain histology and neuroinflammation using Diffusion Basis Spectrum Imaging (DBSI) in cognitively normal midlife individuals.

Importance: The brain and adipose tissue interact metabolically, and if there is a problem with the energy metabolism of the brain, it cannot maintain the energy balance with the adipose tissue. Therefore, when adenylate kinase 5 (), which regulates energy metabolism in the brain, is knocked out, problems with lipid metabolism may occur.
Objective: We aimed to elucidate the metabolic function and phenotype of , a gene with an unknown function in metabolism.

Background: Mounting data indicates that extracellular vesicles (EVs) have the potential to improve the injury after a stroke. Pyroptosis is a recently identified kind of programmed cell death that initiates an inflammatory reaction. We aimed to ascertain the therapeutic implications and possible molecular processes of EVs obtained from adipose-derived stem cells (ADSCs) in inhibiting pyroptosis in ischemic stroke.
