A breakthrough study led by researchers at the Icahn School of Medicine at Mount Sinai has uncovered a vital link between a protein associated with youth and the preservation of brain health. The study, published in the journal Nature Communications, reveals that the protein TIMP2 plays a critical, previously underestimated role in maintaining the health…

A breakthrough study led by researchers at the Icahn School of Medicine at Mount Sinai has unveiled a potential mechanism for combating the cognitive decline associated with aging. Scientists have discovered that a protein known as TIMP2—which is naturally associated with youth—plays a critical role in preserving the health and functionality of the brain’s primary…

For decades, the prevailing dogma in neuroscience held that the human brain was an immunological fortress, a "closed system" largely insulated from the immune defenses operating throughout the rest of the body. Protected by the formidable blood-brain barrier—a specialized network of vessels that restricts the movement of substances and cells from the bloodstream into the…

For decades, the prevailing consensus in neurology was that the devastating neurodegeneration seen in Alzheimer’s disease and related conditions was primarily an internal affair—a localized war occurring behind the formidable barricades of the blood-brain barrier. Scientists focused their efforts on the internal buildup of toxic proteins, such as amyloid plaques and tau tangles, viewing the…

Researchers at the Washington University School of Medicine in St. Louis have uncovered a groundbreaking architectural feature of the human body: previously unknown, lymph node-like immune structures nestled within the bone marrow of the skull. This discovery, published in the journal Nature, fundamentally alters the scientific understanding of how the brain interacts with the body’s…

For decades, the central dogma of neurobiology has held that the brain is an immunologically privileged site—a sequestered, closed system shielded by the blood-brain barrier. Under this long-standing model, the brain’s specialized immune cells, known as microglia, were thought to be established during embryonic development and to remain a self-sustaining, isolated population throughout an individual’s…
