“Findings from a new study shed new light on this link, suggesting that events such as head trauma and stroke accelerate Alzheimer’s disease by activating one of the brain’s major immune cells and triggering an infection-like spread of amyloid-beta tangles to previously unaffected tissues.”

“Optogenetics is a research technique that allows scientists to switch a neuron's activity on or off using light and genetic engineering. They found that older mice had nearly 40 percent fewer hypocretin-producing neurons than younger mice.”

“Nevertheless, the results add to the growing evidence that gene therapies may be a promising way to treat a range of genetic diseases. In episode #77, Dr. George Church discusses revolutionary technologies in the field of genetic engineering.”

“SARS-CoV-2, the virus that causes COVID-19, exploits the ACE2 receptor to gain entry into cells. A specific region of the virus called a spike protein binds to a cell's ACE2 receptor, and the virus injects its genetic material – RNA – into the cytosol.”

“A recent study found that tau-related disorders in both fruit flies and humans are closely linked to neuronal accumulation of glycogen—the stored form of glucose—and that breaking down this glycogen substantially reduces tau-related brain damage.”

“Then they determined whether the preference for sugar (over artificial sweeteners) arises in the brain or the gut using optogenetics. Optogenetics is a research technique that allows scientists to switch a neuron's activity on or off using light and genetic engineering.”

“These variations are common in people of East Asian ancestry (prevalence of low-alcohol-tolerability alleles between 21% and 69%) but rare in people of European descent (prevalence of 0.01% to 4%). People with these genetic variations experience facial redness/flushing, nausea, and a rapid heart beat when they drink.”

“Iron supplementation should be approached cautiously and guided by lab testing when possible. Supplements "Two people can respond totally differently to the same supplement. Genetics, gut health, baseline status—all that matters.”

“Perhaps the most clear-cut examples of cryotherapy’s beneficial effects are observed in the brain, where levels of the hormone and neurotransmitter norepinephrine – responsible for vigilance, attention, focus, and positive mood – increase markedly when the body is exposed to extreme cold.”

“Unlike antibody treatments that target the PCSK9 protein (an important regulator of blood cholesterol levels), which are very expensive, base editing could deliver permanent protection from hypercholesterolemia with just one dose.”
