C1q and immunoglobulins mediate activity- dependent synapse loss in the adult brain Full article and list of author affiliations: https://doi.org/10.1126/ science.adv1219 Gerard Crowley et al. INTRODUCTION: Synaptic elimination is a fundamental process that can engage microglia and the classical complement cascade, yet the mechanisms that specify which synapses are targeted by complement component 1q (C1q), the initiating component of this cascade, remain incompletely understood. Neuronal activity shapes synaptic connectivity, but whether it interfaces with complement pathways to regulate synapse loss in the adult brain, including in disorders such as Alzheimer’s disease (AD), is unclear. …
