The diet-Alzheimer’s connection is more complicated than “eat this, avoid that”

A mini-review finds that dietary patterns may influence Alzheimer’s disease through interconnected pathways involving neuroinflammation, insulin resistance, oxidative stress, blood-brain barrier dysfunction, homocysteine, and the gut-brain axis. The authors argue that genetics, sex, age, physical activity, and socioeconomic context may modify these relationships, supporting more individualized approaches to nutrition research and dementia prevention.

Disrupted brain-immune signaling may help drive neurodegeneration

A Cell perspective argues that neurodegeneration can emerge from disrupted communication between neural and immune networks, with peripheral immunity, microglia, and gene-regulatory programs all shaping disease processes. The authors propose that restoring immune homeostasis and recalibrating neuroimmune circuits could create new therapeutic and diagnostic opportunities, while emphasizing that many mechanisms remain unresolved in humans.

New review highlights spatial technologies in advanced brain mapping

Understanding how molecular changes shape brain function and disease requires more than measuring genes in bulk tissue.

Glioma microenvironment emerges as key target for future therapies

The prognosis for glioma patients remains extremely poor despite aggressive multimodal standard therapy: maximal safe resection, radiotherapy, and temozolomide chemotherapy, with median survival rarely exceeding 15 to 18 months.

Microglial differences found in genetic and sporadic frontotemporal dementia patients

A study by the University of Eastern Finland revealed for the first time clear differences in the function and gene expression of microglial cells from patients with genetic and sporadic types of frontotemporal dementia.

Youth-associated protein reverses age-related microglial changes in mice

Researchers at The Icahn School of Medicine at Mount Sinai have identified a role for the youth-associated protein TIMP2 in supporting the healthy function of microglia, the brain's resident immune cells.

Senescent brain immune cells secrete protein linked to cognitive decline

Brain-resident immune cells that have reached an old-age state called "senescence" secrete a protein that causes dysfunction in other brain cells, according to a study led by investigators at Weill Cornell Medicine.

Shared cellular pathway drives neurodegeneration in rare childhood dementia and Alzheimer’s

Researchers at University of California San Diego and their colleagues have identified a key cellular pathway that drives brain degeneration in both a rare childhood disorder and the far more common Alzheimer's disease.

Comprehensive brain cell map opens new avenues for Alzheimer's therapies

The brain's immune cells are increasingly recognized as key players in Alzheimer's disease, but exactly how they change as the disease develops has remained unclear.

Immune cell interaction timing impacts glioblastoma treatment response

A joint research team led by Professor Sungsu Park of Sungkyunkwan University and Professor Sun-Ha Paek of Seoul National University College of Medicine has demonstrated for the first time that the sequence in which immune cells interact with cancer cells can critically influence the therapeutic response in glioblastoma.

Researchers map how blood cells cross into the brain during aging

The brain's immune system has long been thought to exist independently from the rest of the body, complete with its own specialized immune cells and a blood-brain barrier that limits what can travel into the brain.

New 3D brain tissue model accelerates Alzheimer's drug development

How can Alzheimer's research be made faster, better, and more effective? After decades of intensive research worldwide and despite recent therapeutic advances, scientists have not managed to fully arrest the progress of the disease.

Ketamine boosts neuroplasticity through microglia in female brains

Doctors use ketamine on patients as general anesthesia before surgery. They also prescribe it in low doses for pain management, and more recently, it's been used for treatment-resistant depression where other drugs have failed.

Brain immune cells drive recovery from ketamine anesthesia in females

During ketamine anesthesia, the brain's nerve cells fall silent-as consciousness returns, they begin to reconnect.

Overactive brain immune response linked to rare, severe genetic epilepsy

An overactive immune response in the brain may play a role in Dravet Syndrome, a rare and severe genetic epilepsy that typically begins in infancy, according to Weill Cornell Medicine researchers.

Slow-maturing microglia may enable powerful human cognitive abilities

Microglia are the most common immune cells in the brain, where they defend against intruders and engulf damaged neurons.

Researchers link genome folding to gene activity and brain tissue organization in Alzheimer's

Researchers from Carnegie Mellon University's School of Computer Science, the University of Pittsburgh School of Medicine and the University of Washington shed new light on Alzheimer's disease that could point to new directions for treatment.

Study reveals dynamic remodeling of genome architecture during brain aging

Researchers have discovered that the human brain undergoes widespread age-related changes in genome regulation beginning in midlife that may help explain why aging is the greatest risk factor for neurodegenerative diseases such as Alzheimer's.

Study suggests lipid droplet accumulation is a conserved feature of senescent cells

A new research paper was published in Volume 18 of Aging on July 1, 2026, titled "Senescent cells accumulate lipid droplets."

Brain’s immune cells play key role in maintaining stability of neuronal networks in Alzheimer's disease

Researchers at Trinity College Dublin have discovered that microglia – the main immune cells of the brain – play a critical role in maintaining the stability of neuronal networks in Alzheimer's disease.
