Background: Cardiac surgery triggers sterile innate immune responses leading to postoperative complications. Clonal hematopoiesis (CH) is associated with short-term inflammation-mediated outcomes after cardiac surgery. The impact of CH on long-term postoperative outcomes remains unknown.

- Langerhans cell Histiocytosis (LCH) and Erdheim-Chester disease (ECD) are linked to certain genetic mutations and pose a heightened risk for neurodegeneration, revealing microglia mutant clones in patients' brains.
- These mutant clones lead to symptoms like microgliosis and neuronal loss, notably affecting specific brain regions, with symptoms correlating to the disease's duration and the size of these clones.
- Research suggests that targeting these mutant microglia with a CSF1R-inhibitor could prevent neuronal loss, presenting a potential new treatment option distinct from current MAPK inhibitors.
Somatic genetic heterogeneity resulting from post-zygotic DNA mutations is widespread in human tissues and can cause diseases, however few studies have investigated its role in neurodegenerative processes such as Alzheimer's Disease (AD). Here we report the selective enrichment of microglia clones carrying pathogenic variants, that are not present in neuronal, glia/stromal cells, or blood, from patients with AD in comparison to age-matched controls. Notably, microglia-specific AD-associated variants preferentially target the MAPK pathway, including recurrent CBL ring-domain mutations.

Methods: 52 isolated left CDH and 104 control fetuses were imaged using MRI. Brain morphometry (Biparietal diameter-BPD, brain fronto-occipital diameter-BFOD, third ventricle, posterior ventricles, transcerebellar diameter-TCD, anteroposterior and craniocaudal cerebellar vermis diameter-AP and CC) and cortical structures (bilateral cingulate fissure-CF, insular fissure-IF, insular depth - ID) were compared with controls using Mann-Whitney test.
