“The blood-brain barrier is a highly selective semi-permeable barrier made up of endothelial cells connected via tight junctions. This barrier separates the circulating blood from the brain's extracellular fluid and prevents the entry of substances that may be neurotoxic.”

“The oxidative stress further triggers inflammation, amplifying damage to developing neurons. Microplastics cross the blood-brain barrier Microplastics are finding their way past one of the body’s strongest defenses—the blood-brain barrier—and into the brain itself.”

“Butyrate participates in a wide array of metabolic pathways in the body. Accordingly, low concentrations of butyrate in the blood, colon, liver, and brain have been identified in various diseases. Generally, increasing butyrate levels benefits health.”

“DHA accumulates in cell membranes and can influence embedded receptors and transporters, including glucose transport at the blood-brain barrier. EPA and DHA also produce specialized pro-resolving mediators such as resolvins, protectins, and maresins.”

“To fight the formation of these fibrils, however, a molecule would have to cross the blood-brain barrier -- a series of cell junctions that prevent certain substances from entering the brain.”

“Because omega-3 fatty acids must be in the free fatty acid form or phospholipid form to cross the blood-brain barrier, researchers measured these forms of the fatty acids in the participants' plasma before and after the intervention.”

“FGF21 is typically produced in the liver and fatty tissue, where it controls many aspects of metabolism. But FGF21 is also produced in working muscles. Research shows that FGF21 can cross the blood-brain barrier and bind to receptors in the hypothalamus.”

“Tiny contractile cells surrounding the brain's capillaries called pericytes regulate vascular blood flow and maintain blood-brain barrier integrity. Pericytes detach from the blood vessels in aging, driving the pathophysiology of neurological dysfunction, vascular dementia, and stroke.”

“A recent study in mice found that C. albicans triggers a dual-pronged defense system involving both the brain and the immune system; however, when elements of this system fail, the fungi can impair the blood-brain barrier and drive amyloid plaque formation.”

“Breast milk leukocytes differ from their counterparts in blood, exhibiting unique, highly specialized immune function profiles. Concentrations of leukocytes are highest in colostrum and taper off in transitional milk, eventually reaching a baseline level in mature milk.”
