Microglia and border-associated macrophages show opposing vascular roles in systemic inflammation

A mouse study separates the contributions of parenchymal microglia and border-associated macrophages to cerebrovascular and leukocyte responses during systemic inflammation, underscoring the need to distinguish CNS myeloid compartments.

832,505-cell human myeloid atlas links a GPNMB-high state to aging and Alzheimer's

Profiling 1,607 donors resolves 13 human myeloid subtypes and identifies a phagocytic GPNMB-high microglial state that expands with Alzheimer's pathology, is enriched for polygenic risk, and depends on MITF and TREM2 biology.

Time-resolved neonatal atlas identifies a transient Numb-enriched microglial state

Single-cell profiling of neonatal mouse brain immune cells identifies a neurodevelopment-linked Numb-enriched state that peaks during the second postnatal week and is disrupted by neonatal inflammation.

Somatic lineage tracing finds bone-marrow contribution to aging human microglia

Analysis of 20 older individuals used accumulated somatic mutations and mitochondrial variants to identify bone-marrow-derived cells with microglia-like profiles in every examined brain, challenging a strictly self-renewing model of human microglial maintenance.

Field review argues against binary microglial activation labels

A Nature Reviews Neuroscience synthesis frames microglia as a multidimensional state space shaped by age, sex, genotype, location, environment, and prior immune exposure—reinforcing the limits of resting/activated and M1/M2 terminology.

Cross-disease neurovascular atlas shows disease-specific microglial reactivity

A repository of more than 250,000 mouse vascular and microglial cells finds comparatively stable vascular programs but strong disease-specific microglial responses, including convergence between late-stage TBI and Alzheimer's disease.

Human spatial atlas maps microglial transition at the Aβ–tau inflection point

Spatial transcriptomics and single-nucleus RNA-seq identify early inflammatory and late antigen-presenting plaque-induced gene programs, with distinct patterns in cognitively resilient octogenarians and centenarians.

Biogen concludes Phase 2 evaluating LRRK2 inhibitor BIIB122 in Parkinson's

Biogen and Denali Therapeutics' Phase 2 evaluation (NCT05348785) of the highly selective LRRK2 inhibitor BIIB122 in early-stage Parkinson's disease has completed its clinical cohort. LRRK2 is heavily expressed in microglia where it governs lysosomal degradation.
