“FGF21 also protects against alcohol intoxication." - Dr. Rhonda Patrick. During exercise, fibroblast growth factor 21 (FGF21) is released by our liver and muscles, and it can cross the blood-brain barrier and bind to receptors in the hypothalamus.”

“When NR and NMN were given intravenously at varying doses (50 mg/kg/bw and 500 mg/kg/bw), directly produced NAD+ was present in the liver, kidney, and muscle in a dose-dependent manner. However, the only NAD+ detected in the brain was that which was salvaged from nicotinamide, suggesting that neither NR nor NMN crosses the blood-brain barrier.”

“Obesity alters the blood-brain barrier's integrity, eliciting a cascade of adverse effects that influence many aspects of human health. This review describes the mechanisms that drive obesity-induced blood-brain barrier degradation and its effects.”

“Kynurenic acid is neuroprotective and, importantly, cannot cross the blood-brain barrier. This enzymatic shift significantly reduces the availability of kynurenine to form quinolinic acid in the brain, thereby lowering the neurotoxic burden.”

“Findings from a 2017 study suggest that surgery in combination with the anesthetic drug isoflurane induces blood-brain barrier dysfunction, contributing to cognitive impairment. Anesthetic drugs can be administered orally, intravenously, or via inhalation.”

“Loss of blood-brain barrier integrity increases the risk of many neurodegenerative diseases, including dementia and Alzheimer's. A 2021 study found that having a higher omega-3 index preserves the blood-brain barrier and maintains cognitive function in older adults.”

“Findings from a new study suggest that people with Parkinson's disease have defects that promote poor blood-brain barrier function, impairing angiogenesis and autophagy. The blood-brain barrier is a lining of epithelial (skin-like) cells that exchanges nutrients, waste, and signaling molecules.”

“An analysis of the effects of physical exercise on blood-brain barrier permeability and function and the mechanisms that drive these effects.”

“The structural integrity of the blood-brain barrier is therefore critical for homeostatic maintenance of the brain microenvironment. The study involved 43 patients (average age 58 years) who had been diagnosed with cerebral small vessel disease, as evidenced by having experienced a stroke or demonstrating mild cognitive impairment.”

“Once inside the cell, SARS-CoV-2 replicates, triggering a robust immune response and eliciting widespread inflammation. The blood-brain barrier, a semi-permeable barrier that separates the blood from the brain's extracellular fluid, prevents the entry of neurotoxic substances into the brain.”
