“The bacterium can also interfere with one of the steps involved in xenophagy, ultimately impairing the body's immune response. Similarly, human immunodeficiency virus, or HIV, reduces cellular levels of key proteins involved in xenophagy induction.”

“Acute sleep loss in humans leads to a gain in fat mass and loss of muscle mass due to a disrupted circadian clock that dysregulates metabolism in adipose tissue and decreases structural proteins in skeletal muscle.”

“In human trials of voluntary caloric restriction, however, participants rarely achieve the desired level of restriction and most gradually increase their intake over time. Furthermore, people who follow a calorie-restricted diet tend to gravitate toward higher protein foods, which provide greater satiety.”

“Permeability of the blood-brain barrier, is partially regulated by tight-junction proteins, which form attachments between the cytoskeletons of adjacent cells. High serum phosphate levels, which are common in people with cerebral small vessel disease, downregulate the assembly of tight junction proteins, increasing BBB permeability.”

“Immune cells bear specialized proteins embedded within their membranes that recognize specific microbial molecular patterns. These proteins, called toll-like receptors, detect the presence of bacterial components and signal the body to secrete inflammatory cytokines.”

“Proteins involved in lipid transport and metabolism increased, whereas several ribosomal, sarcomeric, and extracellular-matrix proteins decreased. The researchers did not observe the widespread increase in mitochondrial proteins they had expected.”

“Background Collagens are major structural proteins in numerous body tissues, including tendons, ligaments, cartilage, skin, blood vessels, muscles, gut tissue, and dentin. They are the most abundant proteins in the body, comprising 30 percent of the total protein mass.”

“Sirtuin-activating compounds (SACs) Some naturally occurring and synthetic compounds, called sirtuin-activating compounds, mimic conditions of low cellular energy. Sirtuin activating compounds bind to sirtuins, altering their affinity for NAD+ and their protein substrates, thereby increasing sirtuins' activity.”

“Supplementation favorably affected markers of lipid and protein damage: malondialdehyde rose in the placebo group but fell with vitamins, while protein carbonyls increased in the placebo group but remained stable in the supplemented group.”

“For the overweight and obese diabetics, a low carbohydrate/high fat and protein in the diet was most beneficial for weight control and glycemic status.”
