T Cells Infiltrate Brain and Worsen Alzheimer's Pathology, Study Finds

Cognitive decline associated with Alzheimer's disease (AD) develops when neurons begin to die, which can be caused by inappropriate immune responses and excessive inflammation in the brain triggered by amyloid beta deposits and tau tangles, two hallmarks of the disease.

Sensory Neurons Develop Customized Nerve Endings Based on Cues From the Skin, Finds Study

Nerve cells that sense touch grow the appropriate endings for hairy or hairless skin based on cues from the skin itself, rather than through predetermined programming, according to research led by Harvard Medical School scientists and published Aug. 21 in Developmental Cell.

Direct-to-Consumer Blood Test for Assessing User’s Alzheimer’s Disease Risk

In July, the first direct-to-consumer blood test designed to assess a user’s risk for developing Alzheimer’s disease hit the market. The test, which has not undergone Food and Drug Administration (FDA) review, measures the level of a protein called beta amyloid, a key component of plaques that form in the brains of Alzheimer’s disease patients, disrupting brain function.

Aging Disrupts Gene Expression in Specific Regions of the Brain

Most of us who've reached middle age have noticed a slowing in memory and cognition, but scientists don't have a clear picture of the molecular changes that take place in the brain to cause it.

Xenogeneic-Free Brain Organoids Offer New Hope for Studying Neurodegenerative Diseases

Researchers at University of Michigan developed a method to produce artificially grown miniature brains -; called human brain organoids -; free of animal cells that could greatly improve the way neurodegenerative conditions are studied and, eventually, treated.

Game-Changing Research Shows Astrocytes as Key Regulators of Alzheimer's Disease Progression

Why do some people develop Alzheimer's disease while others don't? And, even more puzzlingly, why do many individuals whose brains are chock-full of toxic amyloid aggregates-;a telltale sign of Alzheimer's brain pathology-;never go on to develop Alzheimer's-associated dementias?
