Hypothalamic SF1 Neurons Help Drive Exercise Endurance Gains

Hypothalamic SF1 Neurons Help Drive Exercise Endurance Gains

TL;DR: A 2026 mouse study in Neuron found that exercise activates ventromedial hypothalamic SF1 neurons, and that this brain response is required for normal endurance gains after training. Key Findings VMH SF1 neurons: Exercise increased activity-linked Bdnf expression in steroidogenic factor-1 neurons in the ventromedial hypothalamus. Training plasticity: Repeated exercise increased both intrinsic excitability and …

GLP-1 Receptor Agonists Not Ready for Acute Stroke Neuroprotection, Review Finds

GLP-1 Receptor Agonists Not Ready for Acute Stroke Neuroprotection, Review Finds

TL;DR: A 2026 narrative review in Journal of Central Nervous System Disease found that glucagon-like peptide-1 receptor agonists have promising stroke-prevention and animal-model evidence, but human data do not yet support routine use as an acute ischemic stroke neuroprotective treatment. Key Findings Search through January 2026: The review covered preclinical stroke models, observational studies, randomized …

Glial Mitochondrial Transfer Protected Sensory Neurons From Neuropathy

Glial Mitochondrial Transfer Protected Sensory Neurons From Neuropathy

TL;DR: A 2026 Nature study found that satellite glial cells can transfer mitochondria to sensory neurons, and blocking that transfer in mice promoted nerve degeneration and neuropathic pain. Key Findings 83.3% transfer: In mouse co-cultures, 83.3% of dorsal root ganglion neurons received mitochondria from satellite glial cells. 31.3% TNT-positive: Visible tunnelling nanotubes were seen in …

Autoimmune Mechanisms May Explain Some Drug-Resistant Focal Epilepsy

Autoimmune Mechanisms May Explain Some Drug-Resistant Focal Epilepsy

TL;DR: A 2026 review in Advances in Clinical and Experimental Medicine argues that autoimmune mechanisms may explain a subset of drug-resistant focal epilepsy, especially when seizures persist despite standard antiseizure drugs and immune markers are present. Key Findings Drug resistance definition: Drug-resistant epilepsy was defined as persistent seizures despite at least two appropriately selected, tolerated, …

Angiopep NK Vesicles Delivered Temozolomide in Glioblastoma Mice

Angiopep NK Vesicles Delivered Temozolomide in Glioblastoma Mice

TL;DR: A 2026 study in Journal of Nanobiotechnology found that Angiopep-2-modified natural killer cell extracellular vesicles carried temozolomide across glioblastoma barriers, reduced mouse tumor bioluminescence, and extended median survival in an orthotopic GBM model. Key Findings 2.5-3.2x uptake: Angiopep-2 modification increased glioblastoma-cell uptake of NK extracellular vesicles compared with unmodified NK-EV. 2.8-3.5x BBB transport: Ang-NK-EV@TMZ …

Amyloid, Tau, and Neurodegeneration Axes Mapped Alzheimer’s Heterogeneity

Amyloid, Tau, and Neurodegeneration Axes Mapped Alzheimer's Heterogeneity

TL;DR: A 2026 preprint in medRxiv used amyloid positron-emission tomography, tau molecular imaging, and structural MRI to build individualized Alzheimer’s disease biomarker axes from ADNI and validate them in OASIS. Key Findings 12,430 ADNI images: The pipeline harmonized longitudinal amyloid-beta and tau positron-emission tomography images plus T1 MRI gray matter images from ADNI. 4,958 OASIS …

Laypeople Named More Alcohol Than Cannabis Intoxication Cues

Laypeople Named More Alcohol Than Cannabis Intoxication Cues

TL;DR: A 2026 study in Drug and Alcohol Review found that laypeople reported more and better-developed cues for alcohol intoxication than cannabis intoxication, even though most coded cues for both substances were accurate. Key Findings Intoxication-cue sample: The survey sample was 77.7% female, with an average age of 20.5 years, and came from undergraduate psychology …

AI Remote Monitoring Studies Favored Parkinson’s but Had High Bias Risk

AI Remote Monitoring Studies Favored Parkinson's but Had High Bias Risk

TL;DR: A 2026 systematic review in BMC Medical Informatics and Decision Making found that AI models using remote-monitoring data were most often studied in Parkinson’s disease, but 56 of 76 prospective studies had high risk of bias. Key Findings 6,668 records were screened: Researchers narrowed the search to 76 prospective studies of machine learning for …

ADAS-Cog-13 Flagged Cognitive Impairment in Older Adults With Focal Epilepsy

ADAS-Cog-13 Flagged Cognitive Impairment in Older Adults With Focal Epilepsy

TL;DR: A 2026 preprint in medRxiv found that the ADAS-Cog-13 cognitive scale detected impairment in older adults with focal epilepsy, but a cutoff of 15 had only modest diagnostic accuracy against an epilepsy-specific neuropsychological standard. Key Findings 83 epilepsy patients: The study analyzed adults older than 55 with focal epilepsy from the Brain, Aging, and …

PF-04995274 5-HT4 Agonist Changed Depression Signals Without SSRI-Like Bias Shift

PF-04995274 5-HT4 Agonist Changed Depression Signals Without SSRI-Like Bias Shift

TL;DR: A 2026 randomized study in The British Journal of Psychiatry found that the experimental 5-HT4 receptor agonist PF-04995274 did not mimic citalopram’s early emotional-bias effects in unmedicated depression, but it was linked with lower depression ratings and increased medial-frontal brain activation after about 1 week. Key Findings 90 randomized adults: The RESTAND study assigned …
