Scientists may have found the key"},"content":{"rendered":"<p style=\"text-align: justify\"><strong style=\"text-align: justify\">For years, scientists have known that regular physical activity is associated with a lower risk of Alzheimer\u2019s disease<\/strong>. However, the exact biological mechanism remained unclear. New research from the University of California, San Francisco, published in Cell in 2026, has identified a liver-produced enzyme called GPLD1 that appears to play a key role in protecting the aging brain.<\/p>\n<p>     \u00a0   \u00a0      \u00a0       <\/p>\n<h2 style=\"text-align: justify\">How exercise strengthens the brain\u2019s protective barrier<\/h2>\n<p style=\"text-align: justify\"><strong style=\"text-align: justify\">The enzyme GPLD1 increases in the bloodstream during exercise and helps reinforce the blood-brain barrier, a protective shield that prevents harmful substances from entering brain tissue<\/strong>. In experiments with mice, higher levels of this enzyme reduced inflammation, limited the leakage of harmful molecules into the brain, and even improved memory performance in older animals.<\/p>\n<p> <img decoding=\"async\" data-document-id=\"cms\/api\/amp\/image\/AA1XLF28\" data-reference=\"image\" src=\"https:\/\/img-s-msn-com.akamaized.net\/tenant\/amp\/entityid\/AA1XLF28.jpg\" style=\"display: block; margin-left: auto; margin-right: auto\"\/> <\/p>\n<h2 style=\"text-align: justify\">Why this discovery matters<\/h2>\n<p style=\"text-align: justify\">As people age, the blood-brain barrier can become weaker and more permeable. <strong style=\"text-align: justify\">This allows inflammatory molecules and toxins to enter brain tissue, which may accelerate processes linked to Alzheimer\u2019s disease, including the buildup of amyloid-beta plaques<\/strong>. By strengthening this barrier, exercise may help slow the early biological changes that contribute to cognitive decline.<\/p>\n<h2 style=\"text-align: justify\">Exercise triggers multiple brain-protective signals<\/h2>\n<p style=\"text-align: justify\">Scientists also note that GPLD1 is only one part of a broader system activated during physical activity. <strong style=\"text-align: justify\">Exercise stimulates muscles and other organs to release molecules such as lactate and irisin, which support brain plasticity, reduce inflammation, and promote healthy neural connections<\/strong>. Together, these signals create a protective environment for the brain.<\/p>\n<p> <img decoding=\"async\" data-document-id=\"cms\/api\/amp\/image\/AA1XLHLW\" data-reference=\"image\" src=\"https:\/\/img-s-msn-com.akamaized.net\/tenant\/amp\/entityid\/AA1XLHLW.jpg\" style=\"display: block; margin-left: auto; margin-right: auto\"\/> <\/p>\n<h2 style=\"text-align: justify\">What this means for future treatments<\/h2>\n<p style=\"text-align: justify\">The discovery opens the possibility of developing therapies that mimic some of the brain benefits of exercise for people who cannot engage in regular physical activity. <strong style=\"text-align: justify\">Still, researchers emphasize that physical movement itself remains one of the most powerful tools currently available to support long-term brain health and potentially reduce the risk of Alzheimer\u2019s disease<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>For years, scientists have known that regular physical activity is associated with a lower risk of Alzheimer\u2019s disease.
