Non-coding RNAs and in particular microRNAs tunes brain cell differentiation and synaptic development and modulates brain functions such as synaptic plasticity, memory formation and behavioral performance.
Our research aims to identify long noncoding RNAs (lncRNAs) and/or microRNAs as well as their interactions, and to investigate their roles in neuronal and glia cells during physiological and pathological conditions. Main focus is the study of these molecules in Ageing and Alzheimer’s Disease (AD).
Primary rodent neural cell cultures, cell lines, human neuronal and glia cells differentiated from iPSC (induced pluripotent stem cells)-derived NSC (neural stem cells) as well as mouse models are instrumental to our studies. Previous findings in our laboratory have shown that miR-101 regulates directly AD-related genes, Amyloid precursor protein (APP) and Ranbp9, in rodent hippocampal neurons in vitro and in vivo (Vilardo et al., 2010; Barbato et al., 2014). More recently we found that inhibition of miR-101post-transcriptional regulation in CA1 hippocampal neurons of adult C57BL/SJ mice, by stereotaxic injection of a lentiviral miRNA sponge, leads to cognitive decline (Barbato et al., submitted). We are now characterizing the molecular pathways involved in hippocampal dependent cognitive decline after miR-101downregulation that may occur during aging and AD. Furthermore, we are searching for lncRNAs that might regulate miR-101 and/or other microRNAs and pathways associated to Ageing/AD
