Microglial Remodeling of the Extracellular Matrix Promotes Synapse Plasticity.

Project description:Synapse remodeling is essential to encode experiences into neuronal circuits. Here, we define a molecular interaction between neurons and microglia that drives experience-dependent synapse remodeling in the hippocampus. We find that the cytokine interleukin-33 (IL-33) is expressed by adult hippocampal neurons in an experience-dependent manner and defines a neuronal subset primed for synaptic plasticity. Loss of neuronal IL-33 or the microglial IL-33 receptor leads to impaired spine plasticity, reduced newborn neuron integration, and diminished precision of remote fear memories. Memory precision and neuronal IL-33 are decreased in aged mice, and IL-33 gain of function mitigates age-related decreases in spine plasticity. We find that neuronal IL-33 instructs microglial engulfment of the extracellular matrix (ECM) and that its loss leads to impaired ECM engulfment and a concomitant accumulation of ECM proteins in contact with synapses. These data define a cellular mechanism through which microglia regulate experience-dependent synapse remodeling and promote memory consolidation.

Microglial Rac1 is essential for experience-dependent brain plasticity and cognitive performance

Project description:Here, we used conditional cell-specific gene targeting in mice with multi-omics approaches, and demonstrated that the RhoGTPase Rac1 was an essential requirement for the microglia to sense and interpret the brain microenvironment, and for crucial microglia-synapse crosstalk driving experience-dependent plasticity. Phosphoproteomics profiling detected a large modulation of RhoGTPase signaling, predominantly of Rac1, in microglia of mice exposed to an environmental enrichment protocol. Ablation of microglial Rac1 affected pathways involved in microglia-synapse communication, disrupted experience-dependent synaptic remodeling, and blocked the gains in learning, memory and sociability induced by environmental enrichment.

Microglial Rac1 is essential for experience-dependent brain plasticity and cognitive performance

Project description:Microglia, the largest population of brain immune cells, continuously interact with synapses to maintain brain homeostasis. We aimed at understanding the role of Rac1 on microglia functions. Here, we used conditional cell-specific gene targeting in mice with multi-omics approaches, and demonstrated that the RhoGTPase Rac1 was an essential requirement for the microglia to sense and interpret the brain microenvironment, and for crucial microglia-synapse crosstalk driving experience-dependent plasticity, a fundamental brain property impaired in several neuropsychiatric disorders.

Astrocyte-derived Interleukin-33 promotes microglial synapse engulfment and neural circuit development II

Project description:Neuronal synapse formation and remodeling is essential to central nervous system (CNS) development and is dysfunctional in neurodevelopmental diseases. Innate immune signals regulate tissue remodeling in the periphery, but how this impacts CNS synapses is largely unknown. Here we show that the IL-1 family cytokine Interleukin-33 (IL-33) is produced by developing astrocytes and is developmentally required for normal synapse numbers and neural circuit function in the spinal cord and thalamus. We find that IL-33 signals primarily to microglia under physiologic conditions, that it promotes microglial synapse engulfment, and that it can drive microglial-dependent synapse depletion in vivo. These data reveal a cytokine-mediated mechanism required to maintain synapse homeostasis during CNS development.
