**Molecular Mechanism and Rationale** The complement component 1q (C1q) represents a critical molecular bridge between innate immunity and synaptic plasticity in the central nervous system. C1q is a hexameric glycoprotein composed of three distinct polypeptide chains (C1qA, C1qB, and C1qC) that forms the recognition component of the classical complement pathway. Under physiological conditions, C1q is constitutively expressed by microglia and plays essential roles in developmental synaptic pruni

# Complement C1q Suppression as Mechanism Linking Exercise Plasma to PV Interneuron Protection ## Introduction and Mechanistic Framework Parvalbumin (PV)-positive GABAergic interneurons constitute a critical subpopulation responsible for generating gamma-frequency oscillations (30-80 Hz), which are essential for hippocampal-cortical network synchronization and higher cognitive function. These interneurons are exceptionally vulnerable in multiple neurodegenerative conditions, including Alzheime
