DNA damage and neurodegenerative disorders are intimately linked but the underlying mechanism remains elusive. Here, we show that persistent lesions in tissue-resident macrophages carrying an XPF-ERCC1 repair defect trigger neuroinflammation neuronal cell death mice. We find microglia accumulate dsDNAs chromatin fragments cytosol, which sensed thereby stimulating a viral-like immune response

Neuroinflammation is a hallmark of many neurodegenerative diseases (NDs) and plays fundamental role in mediating the onset progression disease. Microglia, which function as first-line immune guardians central nervous system (CNS), are drivers neuroinflammation. Numerous human postmortem studies vivo imaging analyses have shown chronically activated microglia patients with various acute chronic neuropathological diseases. While microglial activation common feature NDs, exact pathological states complex often contradictory. However, there consensus that play biphasic conditions, detrimental protective phenotypes, overall response different phenotypes depends on nature duration inflammatory insult, well stage disease development. This review provides comprehensive overview current research responses health, aging, special emphasis heterogeneous phenotypic such hemorrhagic stroke (HS), Alzheimer's (AD), Parkinson's (PD). The primary focus translational preclinical animal models bulk/single-cell transcriptome samples. Additionally, this covers key receptors signaling pathways potential therapeutic targets to regulate during aging NDs. age-, sex-, species-specific differences will be briefly reviewed.

The neurotransmitter dopamine is a key factor in central nervous system (CNS) function, regulating many processes including reward, movement, and cognition. Dopamine also regulates critical functions peripheral organs, such as blood pressure, renal activity, intestinal motility. Beyond these functions, growing body of evidence indicates that an important immunoregulatory factor. Most types immune cells express receptors other dopaminergic proteins, take up, produce, store, and/or release dopamine, suggesting immunomodulation for function. Targeting pathways could be promising avenue the treatment inflammation disease, but despite increasing research this area, data on specific effects disease remain inconsistent poorly understood. Therefore, review integrates current knowledge role cell function inflammatory signaling across systems. We discuss understanding regulation CNS tissues, highlighting diseases Parkinson’s several neuropsychiatric conditions, neurologic human immunodeficiency virus, bowel rheumatoid arthritis, others. Careful consideration given to influence experimental design results, we note number areas need further research. Overall, our immunology at cellular, tissue, level prompts development therapeutics strategies targeted toward ameliorating through immunity.

In Parkinson's disease (PD), neurotoxic microglia, Th1 cells, and Th17 cells are overactivated. Overactivation of these immune exacerbates the process leads to pathological development pro-inflammatory cytokines, chemokines, contact-killing compounds, causing loss dopaminergic neurons. So far, we have mainly focused on role specific class in PD while neglecting impact interactions among disease. Therefore, this review demonstrates reciprocal interplays between microglia T associated subpopulations through cytokine chemokine production that impair and/or protect PD. Furthermore, potential targets models neuroinflammation highlighted provide new ideas/directions for future research.

Quantification of microglial activation through morphometric analysis has long been a staple the neuroimmunologist’s toolkit. Microglial morphological phenomics can be conducted either manual classification or constructing digital skeleton and extracting data from it. Multiple open-access paid software packages are available to generate these skeletons via semi-automated and/or fully automated methods with varying degrees accuracy. Despite advancements in morphometrics (quantitative measures cellular morphology), there limited development tools analyze datasets they generate, particular those containing parameters tens thousands cells analyzed by pipelines. In this review, we compare critique approaches using cluster machine learning driven predictive algorithms that have developed tackle large datasets, propose improvements for methods. particular, highlight need commitment open science groups developing classifiers. Furthermore, call attention communication between strong engineering/computer background neuroimmunologists produce effective analytical simplified operability if see their wide-spread adoption glia biology community.

Abstract Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease with poorly understood clinical heterogeneity, underscored by significant differences in patient age at onset, symptom progression, therapeutic response, duration, and comorbidity presentation. We perform stratification analysis to better understand the variability ALS pathology, utilizing postmortem frontal motor cortex transcriptomes derived from 208 patients. Building on emerging role of transposable element (TE) expression ALS, we consider locus-specific TEs as distinct molecular features during stratification. Here, identify three unique subtypes this cohort, survival. These results suggest independent mechanisms drive some heterogeneity ALS.
