A man with a slow-progressing, genetically rare form of ALS became the first person to receive an antisense oligonucleotide therapy designed specifically to target his causal mutation. A year later, he reported improved symptoms and remains able to work as a physician, according to results published in Med.
Investors are reportedly re-entering rare-disease drug stocks after the departure of stricter FDA regulators under the Trump administration. The shift in agency leadership has reduced concerns about tougher approval hurdles that had previously discouraged investment in this biotech segment.
Researchers analyzed human brain tissue samples from people with and without Alzheimer's disease and identified more than 1,000 microproteins that had previously gone undetected. Dozens of these small proteins showed different expression levels in Alzheimer's-affected brains compared with healthy ones. Separately, a mouse study found that immune cells activated by gut infections can travel to the brain's protective membrane and remain there as a lasting defensive memory.
Researchers propose that Alzheimer's disease progresses through distinct molecular and cellular phases marked by biological thresholds, rather than a simple straight-line path from amyloid buildup to Tau pathology to neurodegeneration. At these thresholds, cells lose homeostatic balance and shift behavior, with these altered states spreading unevenly across brain tissue and eventually reaching regions critical to cognition. A key threshold identified is when amyloid triggers Tau phosphorylation, marking the transition from amyloid-driven tissue states to ones dominated by neuronal stress responses.
Scientists at the Salk Institute and collaborators combined multiple detection techniques to identify over 4,300 previously unrecognized 'microproteins' in postmortem brain tissue from the dorsolateral prefrontal cortex, comparing samples from people with and without Alzheimer's disease. Dozens of these tiny proteins, each under 150 amino acids, showed altered levels in Alzheimer's patients, and the findings were published in Nature Aging on September 14.
The Rat and Mouse Gazette published detailed guidance for owners caring for severely ill or aging rats, covering isolation from cage mates, warmth, bedding, and hygiene. It recommends moving very sick rats to a separate aquarium with soft bedding like old T-shirts, using a wrapped heating pad for warmth, and gently wiping down rats too weak to groom themselves.
Researchers examined the physics of toilet flushing and found that the aerosol plume generated can rise rapidly and disperse droplets to roughly face height within seconds. They identified specific factors, including flush design and water pressure, that increase how far and how high these microbial-laden particles travel.
A case report documents an instance of southern tick-associated rash illness (STARI) diagnosed in New York, a region well outside the disease's traditional southern range. The finding adds to evidence that the condition, which mimics Lyme disease symptoms, is spreading northward as tick populations shift.
Physicians at Houston's Ben Taub Hospital have documented a cluster of previously undiagnosed kidney failure cases among young, otherwise healthy immigrant laborers from Mexico and Central America. Internist Ricardo Nuila suspects these cases resemble chronic kidney disease of unknown origin (CKDu), a condition long seen among sugarcane workers in El Salvador and other Central American countries but never before confirmed in the United States. The patients, many employed in physically demanding outdoor jobs like roofing, painting, and road paving, now require dialysis several times a week to survive.
A phase of clinical testing involving sixteen patients with multiple sclerosis and related autoimmune disorders showed symptom improvement after researchers used a modified virus to instruct T cells inside the body to produce chimeric antigen receptors, targeting the B cells responsible for autoimmune attacks. The findings, published this week in The New England Journal of Medicine, mark one of the first demonstrations that CAR-T therapy can be generated directly inside a patient rather than engineered in a lab and reinfused.
A new review synthesizes the evolving treatment landscape for metabolic dysfunction-associated steatohepatitis (MASH), the liver disease formerly called NASH, drawing on updated epidemiological data, revised diagnostic terminology, and studies on liver fibrosis assessment. It outlines existing approaches alongside emerging therapies aimed at addressing the disease's metabolic, cardiovascular and cancer-related complications.
A scientist who has logged 10,000 papers in a reference manager over 13 years describes moving from trying to read every paper closely to a selective, task-driven approach to the literature. The piece also warns that AI tools like ChatGPT, despite improved search and summarization, still risk producing uncritical or fabricated citations if used without careful reading.
