Exploratory experiment designed to discover new patterns targeting C1q, C3 in microglia and synapses (in vivo and in vitro). Primary outcome: synaptic pruning mediated by complement pathway
This experiment examined how bacterial extracellular vesicles trigger excessive synaptic pruning through activation of the complement cascade, specifically the C1q-C3 pathway. The study investigated the molecular mechanisms by which bEV-activated microglia mediate synaptic loss, a key pathological feature in Alzheimer's disease. The research likely involved measuring synaptic markers, complement protein expression, and synaptic connectivity in response to bEV treatment, demonstrating a direct link between gut microbiota-derived vesicles and synaptic pathology.
