Glioblastoma Long-Read Single-Cell Sequencing Found Tumor-Specific Isoforms

July 4, 2026 by BrainASAP

TL;DR: A 2026 Nature Communications study used long-read single-cell RNA sequencing to map full-length isoforms in glioblastoma and found tumor-specific transcripts that short-read methods often miss. Key Findings 27 GBM samples: Researchers profiled histologically confirmed IDH-wildtype glioblastoma samples using matched short-read and long-read single-cell sequencing. 100 million reads: The optimized long-read workflow produced a median …

rTMS Plus Risperidone Improved Schizophrenia Cognitive and Aggression Scores

July 4, 2026 by BrainASAP

TL;DR: A 2026 randomized controlled study in Pakistan Journal of Pharmaceutical Sciences found that adding 20 Hz repetitive transcranial magnetic stimulation (rTMS) to risperidone was linked with lower cognitive-factor and aggression scores after 4 weeks in schizophrenia patients. Key Findings Schizophrenia trial sample: The single-center trial randomized 80 patients, with 40 assigned to risperidone alone …

GPR3 Linked CREB Signaling to Presynaptic Maturation

July 4, 2026 by BrainASAP

TL;DR: A 2026 cellular neuroscience study in iScience found that GPR3, a constitutively active G-protein-coupled receptor, behaved like an immediate-early gene and helped connect CREB signaling to presynaptic maturation during neuronal differentiation. Key Findings Biphasic GPR3 induction: Gpr3 rose quickly after nerve growth factor stimulation, dipped, then increased again during later neuronal differentiation. NET-CAGE promoter …

GLP-1 Agonists Reduced Fat Mass With Modest Lean-Mass Loss

July 4, 2026 by BrainASAP

TL;DR: A 2026 systematic review and meta-analysis in International Journal of Obesity found that glucagon-like peptide-1 receptor agonists, metabolic drugs that extend a satiety and glucose-control hormone pathway, reduced body weight mainly through fat loss while lean-mass reductions were generally modest. Key Findings 36 studies reviewed: Researchers included 36 studies in the qualitative review and …

Brief Yoga Raised Heart Rate but Not Cortisol in Stress Pilot

July 4, 2026 by BrainASAP

TL;DR: A 2026 randomized pilot study in JMIR Formative Research found that one brief yoga session did not significantly change salivary cortisol compared with quiet sitting, but it did raise heart rate during the active movement phase. Key Findings Yoga pilot sample: The pilot randomized 19 adults, with 10 participants assigned to a 24-minute yoga …

Brain-Derived p-tau217% Better Classified Alzheimer Pathology

July 3, 2026 by BrainASAP

TL;DR: A 2026 preprint in medRxiv found that brain-derived p-tau217%, a blood marker designed to isolate central nervous system tau, classified Alzheimer disease pathology better than standard plasma p-tau217 in several Alzheimer cohorts. Key Findings CNS-selective ratio: The proposed marker, brain-derived p-tau217%, estimates the share of circulating tau that is both brain-derived and phosphorylated at …

Astrocyte Glucocorticoid Receptor Signaling Restricted Visual Cortex Plasticity

July 3, 2026 by BrainASAP

TL;DR: A 2026 mouse study in Nature found that the astrocyte glucocorticoid receptor pathway helped mature visual cortex circuitry and restricted ocular dominance plasticity, linking light exposure, stress-hormone input, and astrocyte-driven circuit closure. Key Findings 70,907 cells profiled: SHARE-seq mapped RNA expression and chromatin accessibility across visual cortex development in normal-reared and dark-reared mice. Five …

ASPECTS and CT Perfusion Predicted Stroke Outcomes Similarly

July 3, 2026 by BrainASAP

TL;DR: A 2026 study in the International Journal of General Medicine found that rapid ASPECTS scoring on non-contrast CT and CT perfusion core-infarct volume predicted 90-day outcomes similarly in 82 acute ischemic stroke patients treated with endovascular therapy. Key Findings 82 stroke patients: The retrospective single-center study included acute ischemic stroke patients treated with endovascular …

Adaptive DBS Reduced Falls in Parkinson’s Gait Feasibility Trial

July 3, 2026 by BrainASAP

TL;DR: A 2026 randomized feasibility trial in Nature Medicine found that gait-synchronized adaptive deep brain stimulation was feasible and safe in 5 people with Parkinson’s disease, with early findings of improved gait symmetry, lower variability, and fewer reported falls than continuous stimulation. Key Findings 5 Parkinson’s patients: The 1-center feasibility trial enrolled people with Parkinson’s …

Autism fMRI Subtypes Linked to Synaptic and Immune Pathways

July 3, 2026 by BrainASAP

TL;DR: A 2026 Nature Neuroscience study used cross-species functional MRI (fMRI) connectivity to identify hypoconnectivity and hyperconnectivity autism subtypes linked to different synaptic and immune-related biological pathways. Key Findings 20 mouse models: Autism-relevant mouse models clustered into 11 hypoconnectivity-dominant and 9 hyperconnectivity-dominant fMRI patterns. 1,976 human scans: The human dataset included 940 autistic individuals and …
