[ad_1] Delivery of TGF-β1 Following Heart Attack Reduces Reperfusion Injury A heart attack is triggered by rupture of an atherosclerotic plaque and downstream blockage of an important vessel feeding oxygenated blood to heart tissue. Much of the permanent harm resulting from a heart attack occurs when blood flow is restored to ischemic tissue, however. … Read more
[ad_1] The question of whether there are long-lived molecules in long-lived neurons in the brain is an interesting one. Are there specific molecules in the brain that never get replaced across a lifetime, and thus might be vulnerable to damage in the form of modifications that disrupt function? This remains a somewhat hypothetical concern, … Read more
[ad_1] As some of you know, Repair Biotechnologies is the company I co-founded with Bill Cherman back in 2018. We’ve been working on an approach to reverse atherosclerosis for much of that time, and matters have progressed through the stage of great data in mice to present preparations for a pre-IND meeting with the … Read more
[ad_1] Merging the non-profits SENS Research Foundation and Lifespan.io is one of those ideas that makes a lot of sense in hindsight. SENS Research Foundation is research focused and very much interested in expanding into patient advocacy, as it depends on philanthropic funding. Lifespan.io is a patient advocacy organization that is very much interested … Read more
[ad_1] Researchers here describe a mechanism that reduces the ability of microglia to ingest and clear misfolded amyloid-β, the protein aggregates associated with Alzheimer’s disease. Interestingly, this involves APOE, and thus might be affected by the different APOE variants connected to Alzheimer’s disease risk. The researchers demonstrate that interfering in the interaction between APOE … Read more
[ad_1] Regulatory systems that detect low levels of the essential amino acid methionine are one of the more important triggers for the metabolic response to fasting and calorie restriction. Methionine is not manufactured in mammalian cells, can only be obtained from the diet, but is nonetheless essential for protein synthesis. Thus reducing only methionine … Read more
[ad_1] The aged immune system becomes consistently biased towards inflammation, existing in a state of constant low-grade unresolved inflammatory signaling. This changes cell behavior for the worse, and is disruptive to processes that require transient inflammation and participation of immune cells, such as regeneration following injury, or clearance of infectious pathogens. Here researchers discuss … Read more
[ad_1] While early senolytic therapies to clear senescent cells do well in mice, clearing a third to a half of the lingering senescent cells in some tissues and rapidly reversing many aspects of aging, to go much further than this will require a greater understanding of cellular senescence. Unfortunately, it is becoming clear that … Read more
[ad_1] LyGenesis has been working towards liver organoid transplantation as a treatment for liver failure for some years now. Organs such as the liver, thymus, and a few others do not need to be in any specific place in the body to carry out many of their varied functions. Some of the vital work … Read more
[ad_1] Variations in the relative proportions of microbial species making up the gut microbiome apparently contribute to variations in LDL-cholesterol in the bloodstream. Lower LDL-cholesterol sustained over a lifetime produces a slower development of atherosclerotic plaque, and lower risk of consequent cardiovascular disease. While it seems likely there is no one optimal gut microbiome, … Read more
