Early-life inflammation increases aggressive behavior in adult male mice through an astrocyte-neuron signaling
Abstract
Accumulating research has demonstrated a significant association between early-life inflammation and behavioral disorders later in life. However, the effects of early-life inflammation on aggressive behavior in adulthood remain poorly understood. Here, we show that early-life inflammation induced by lipopolysaccharide (LPS) upregulated neuronal dynamin-related protein 1 (DRP1) and impaired mitochondrial function in medial prefrontal cortex (mPFC) of adult mice, thereby increasing aggressive behavior in adulthood. We further identify that CCAAT/enhancer binding protein β (C/EBPβ) is the transcription factor of Dnm1l, which was activated by an increased release of lysophosphatidic acid (LPA) induced by early-life inflammation. Moreover, the overproduction of LPA was due to a specific increase in astrocyte-secreted autotaxin (ATX). Specific knockdown of astrocytic ATX reduced early-life inflammation-induced aggression in wild-type mice, but not in Thy1-C/EBPβ transgenic mice. Remarkably, coenzyme Q10 decreased early-life inflammation-induced aggressive behavior in adult mice. Altogether, these findings provide new insights into the molecular mechanisms by which early inflammation promotes aggressive behavior in adulthood.
