Project description:Trauma-related disorders arise from inefficient fear extinction and have immeasurable social and economic costs. Here, we characterized mouse phenotypes that spontaneously show individual differences in adaptive or maladaptive fear extinction and, before the traumatic experience, we found that specific morphological, electrophysiological and transcriptomic patterns of fear matrix pyramidal neurons predispose to trauma-related disorders. Finally, by using an optogenetic approach we showed the possibility to rescue the inefficient fear extinction activating fear matrix infralimbic pyramidal neurons

Project description:Transcript profiles of H. annosum from different tissues and mycelium grown on different substrates and under different stresses were analyzed. The array probes were designed from gene models taken from the Joint Genome Institute (JGI, department of energy) H. irregulare genome sequence version 1. One aim of this study was to compare gene expression profiles of H. annosum during saprotrophic growth on topsoil from mineral soil, drained and undrained peatland.

Project description:The experiment at three long-term agricultural experimental stations (namely the N, M and S sites) across northeast to southeast China was setup and operated by the Institute of Soil Science, Chinese Academy of Sciences. This experiment belongs to an integrated project (The Soil Reciprocal Transplant Experiment, SRTE) which serves as a platform for a number of studies evaluating climate and cropping effects on soil microbial diversity and its agro-ecosystem functioning. Soil transplant serves as a proxy to simulate climate change in realistic climate regimes. Here, we assessed the effects of soil type, soil transplant and landuse changes on soil microbial communities, which are key drivers in Earth’s biogeochemical cycles.

Project description:Social anxiety disorder is characterized by a persistent and abnormal fear and avoidance of social situations, but available treatment options are rather unspecific. Using an established mouse social fear conditioning (SFC) paradigm, we profiled gene expression and chromatin alterations after acquisition and extinction of social fear within the septum, a brain region important for social fear and social behaviors. We validated coding and non-coding RNAs and found specific isoforms of the long non-coding RNA Meg3 to be regulated depending on the success of social fear extinction. In vivo knockdown of specific Meg3 isoforms in conditioned mice resulted in impaired social fear extinction, as revealed by lower social investigation levels at the end of the extinction training, accompanied with increased baseline activity of the PI3K/AKT signaling pathway. Using ATAC-Seq and CUT&RUN, we characterized alterations in chromatin level after social fear extinction and identified Auts2 and Dclk3 as potential targets of Meg3.

Project description:Drug addiction represents a pathological form of learning and memory with profound implications for individuals and society. The serotonin receptor 5-HT6R, uniquely expressed on primary cilia, is associated with neurological development, cognitive impairments, emotional disorders, and reward memory for cocaine and nicotine. However, its role in morphine-related reward memory remains unclear. This study demonstrated that 5-HT6R expression was downregulated during the early stage of morphine-induced conditioned place preference (CPP) extinction but returned to baseline levels later, with no significant changes observed during CPP establishment or reinstatement. Knocking down 5-HT6R accelerated CPP extinction, while overexpression prolonged the process. Furthermore, primary cilia defects within the mPFC were noted during the early stage of CPP extinction, and the removal of primary cilia expedited this process. Finally, ATR was identified as a novel target molecule of 5-HT6R, and the 5-HT6R-ATR-primary cilia network was found to regulate morphine-induced CPP extinction, offering new insights for opioid addiction therapy.
