Umbilical Cord Exosomes Reduced ICH Neuroinflammation in Rats

by GLOOM

MHD featured image for umbilical cord exosomes and intracerebral hemorrhage neuroinflammation.

A 2026 rat and astrocyte study found that human umbilical cord mesenchymal stem cell exosomes given 6 hours after experimental intracerebral hemorrhage reduced pro-inflammatory signaling and improved neurological recovery scores through the PI3K/AKT/PKM2/H3K18la pathway.1 The result is a mechanistic preclinical signal, not an emergency treatment for human brain hemorrhage. Research Highlights Exosomes were timed early: …

Schizophrenia MRI Subtypes Split 3,958 Patients Into 2 Patterns

by GLOOM

MHD featured image for schizophrenia MRI cortical-gradient subtypes.

A 2026 ENIGMA structural MRI preprint involving 3,958 people diagnosed with schizophrenia and 5,489 controls found 2 cortical-alteration subtypes rather than 1 uniform brain pattern.1 The result maps heterogeneity: anterior-cingulate and temporoparietal network patterns may separate patients, but the result is not a diagnostic MRI test. Research Highlights Large MRI base: The analysis included 3,958 …

Krabbe Disease Base Editing: 0.5% DNA Correction Improved Mice

by GLOOM

MHD featured image for base editing of GALC in Krabbe disease mice.

A 2026 twitcher-mouse study found that adenine base editing corrected only about 0.5% of genomic DNA and 5% of mRNA in a Krabbe disease model, yet that low editing signal restored GALC enzyme activity to about 5% of wild-type levels and reduced psychosine by about 47%.1 This mouse experiment shows why even small correction fractions …

Leigh Syndrome Brain Organoids: Azoles Rescued Lactate 20%

by GLOOM

MHD featured image for Leigh syndrome brain organoid drug screening.

A 2026 Leigh syndrome study combined a cell-type-specific deep-learning screen with a 2,250-drug yeast survival screen and found the same drug family from both directions: azoles, with talarozole and sertaconazole lowering lactate release by 20% in SURF1-mutant midbrain organoids.1 The finding is preclinical, but it is stronger than a single in silico hit because the …

Entorhinal Dopamine Fails Early in Alzheimer’s Mice

by GLOOM

Editorial card showing the lateral entorhinal cortex with dopamine projections from the midbrain, illustrating an early-Alzheimer's mechanism finding rescued by L-DOPA in mice.

A 2026 Nature Neuroscience study from the Igarashi lab proposes a circuit-level answer for why the lateral entorhinal cortex (LEC) is the first cortical region to falter in Alzheimer’s: dopamine inputs from the VTA and substantia nigra to the LEC go functionally silent at the earliest disease stage in an APP knock-in mouse — before …

Heart Failure Depression Linked to Oral Health and Microbiome Dysbiosis

by GLOOM

MHD featured image for emotional disorders, heart failure, and oral microbiome research.

A 2026 analysis linked emotional disorders in heart failure to poorer cardiovascular health, oral-health burden, and oral microbiome dysbiosis, but the strongest mediation signal came from oral health rather than systemic immune-inflammation index.1 In fully adjusted NHANES models, emotional disorders were associated with lower Life’s Essential 8 cardiovascular health, OR 0.39, while self-rated oral health …

Infrasound Raised Cortisol and Irritability Without Conscious Detection

by GLOOM

MHD featured image for infrasound, cortisol, and negative mood appraisal.

A 36-person experiment found that 18 Hz infrasound raised salivary cortisol and negative mood appraisal even though participants did not detect the infrasound above chance (p = 0.241).1 The result is a controlled acute signal, not proof that every real-world low-frequency noise complaint is physiologically caused by infrasound. Research Highlights Cortisol rose with infrasound: Infrasound …
