Parasite Infections and Mental Health: 5 Gut-Brain Immune Routes

by GLOOM

MHD featured image for parasite infections, neuroinflammation, and mental health.

A 2026 Journal of Neuroinflammation review organized parasite-linked neuropsychiatric risk around 5 gut-immune-brain routes; direct CNS parasitic disease carries the clearest signal, while broader mood and cognition associations usually remain observational and confounded.[1] Research Highlights 5 pathways converge on brain function: the 2026 review connected parasite exposure to peripheral cytokines, gut dysbiosis, intestinal permeability, blood-brain …

Alzheimer’s Amyloid Plaques Recruit CD8 T Cells Through Type I Interferon

by GLOOM

MHD featured image for Alzheimer's amyloid plaques, CD8 T cells, type I interferon, and CXCL10 signaling.

A 2026 single-cell and spatial-transcriptomics study of 21,156 brain immune cells found that late amyloid disease shifted interferon-driven neuroinflammation from microglia toward plaque-associated CD8 T cells, with T-cell frequency strongly tracking total amyloid deposits (Spearman rho = 0.844, p < 0.0001).1 The result does not turn Alzheimer’s disease into an autoimmune disease, but it makes …

sCD27 Biomarker Flags Autoimmune Disease in Severe Psychiatric Disorders

by GLOOM

MHD featured image for sCD27, autoimmune disease, severe psychiatric disorders, and neuroinflammation biomarker triage.

A 2026 immunopsychiatry cohort study found that soluble CD27 (sCD27), a marker of T-cell activation, was positive in cerebrospinal fluid in 23% of severe psychiatric patients selected for suspected immune involvement and in 88% of multiple sclerosis patients used as a positive-control group. In the psychiatric cohort, combined cerebrospinal fluid or blood sCD27 positivity was …

Autism Gene-Expression Study Finds 3 Molecular Subtypes in 1,711 Samples

by GLOOM

Photoreal illustration of brain with three highlighted gene-expression patterns showing distinct autism molecular subtypes.

A 2026 RNA-seq analysis of 1,711 autistic probands found 3 gene-expression clusters: 425 people with more severe restricted and repetitive behaviors than the other clusters, 282 with milder symptoms and better adaptive function than the other clusters, and 1,004 with stronger social-communication impairment than the other clusters.1 The supported claim is molecular stratification, not a …

Caffeine to Prevent Alzheimer’s Disease via Adenosine A2A Receptors? (2023 Review)

by GLOOM

Alzheimer’s Disease (AD), a prevalent form of dementia, poses significant challenges for individuals and healthcare systems worldwide. Current treatments primarily offer symptomatic relief without altering the disease’s progression. However, emerging research suggests that caffeine, a widely consumed psychoactive substance, may have neuroprotective properties against AD. Highlights: Alzheimer’s Disease is the most common form of dementia, …

Neuromodulation Therapies to Treat Neuroinflammation in Anxiety & Depression (2023 Research)

by GLOOM

The intersection of neuromodulation, neuroinflammation, and their roles in mood disorders like anxiety and depression represents a significant stride in mental health research. This complex interplay underscores the potential of novel therapeutic strategies targeting the brain’s inflammatory pathways, offering new hope for effective management of these pervasive conditions. Highlights: Link Between Neuroinflammation and Mood Disorders: …

Fatty Acid Sensor GPR120 (FFAR4) Treatment Target for Anxiety & Neuroinflammation (2023 Study)

by GLOOM

In the quest to understand the intricate relationship between our diet, brain, and behavior, scientists are turning their focus to a unique receptor, GPR120. This protein, known for interacting with long-chain fatty acids like omega-3s, is shedding new light on how our body’s inflammation and metabolism can directly affect our mental health. By exploring GPR120’s …
