A comprehensive study of the adult mouse brain transcriptome: analysis of inter-individual differences in cognitive aging and cell-type specific changes in the hippocampus upon voluntary exercise
(2023-12-19)The hippocampus (HPC) is a brain region crucial for learning and memory processes, and this link between the HPC and cognition has been extensively studied in recent decades. Previous research has demonstrated that external ... -
Epitranscriptomic Regulation in Synaptic Plasticity, Aging and Neurodegeneration
(2023-02-03)The regulation of synaptic transmission and plasticity is essential for correct brain function, especially for learning and memory, while the weakening of synaptic transmission and loss of plasticity are hallmarks of the ... -
Recycling as a mechanism for extracellular matrix remodeling at the synapse
(2021-12-10)In the adult brain, the extracellular matrix (ECM) forms lattices that sheath neurons and synapses. The exceptional longevity of ECM molecules lends these lattices a unique durability, and as such, they are deemed to ... -
Establishing parameters for the characterization of rare neurometabolic and neurodegenerative diseases using mass-spectrometry based Metabolomics
(2021-10-18)Rare diseases are a class of disorders where every single disease has a low prevalence, but due to their incredible variety, they affect more than 100 million people worldwide. A significant number of these disorders lead ... -
A cortical hierarchy for differential GABAergic circuit motifs as targets for stress-induced alterations in endocannabinoid signaling
(2021-09-17)Aberrant endocannabinoid (eCB) signaling has been implicated in the pathophysiology of different stress-related psychiatric diseases, such as schizophrenia, depression, and anxiety disorders. Such eCB signaling is triggered ... -
Cocaine-induced synaptic changes in the nucleus accumbens: role in drug-motivated behaviour and relapse risk
(2021-05-17)Chronic drug use creates robust and durable memories which, even after years of abstinence, can be reawakened by drug-associated cues and trigger craving and relapse. Addictive drugs elevate extracellular dopamine levels ... -
Investigation of brain networks for personalized rTMS in healthy subjects and patients with major depressive disorder: A translational study
(2021-02-19)Depression is a complex psychiatric disorder with emotional dysregulation at its core. The first line of treatment includes cognitive behaviour therapy and pharmacological antidepressants. However, up to one third of ... -
Therapeutic approaches for two distinct CNS pathologies
(2020-06-19)This work summarizes the analysis of two distinct therapeutic approaches for the central nervous system (CNS) pathologies, Pelizaeus-Merzbacher disease (PMD) and Glioblastoma multiforme (GBM). PMD is a severe leukodystrophy ... -
Role of prion protein in synucleinopathies
(2020-06-11)Synucleinopathies comprise a group of neurodegenerative diseases, characterized by deposits of aggregated alpha-synuclein (aSyn) in neurons and glia. The special hallmark is the presence of Lewy bodies and Lewy neuritis, ... -
Multi-omics analysis of human brain tissue and an animal model of Parkinson’s Disease
(2020-01-24)Parkinson’s Disease (PD) is the second most prevalent and fastest-growing neurological disorder. The number of affected individuals is expected to double in the next 20 years. The exact molecular mechanisms underlying PD ... -
Lysosomal and mitochondrial crosstalk: the role of lysosomal signaling on mitochondrial biogenesis and function
(2018-11-15)Defects in metabolism result in various diseases, with neurodegeneration being one of the most prevalent consequences. Mitochondria and lysosomes are long known to be fundamental for cellular metabolism. In addition to ... -
The role of alpha-synuclein on transcriptional deregulation in Parkinson’s disease
(2018-08-31)Parkinson’s disease (PD) is a complex neurodegenerative disorder that manifests through a broad ran ge of motor and non - motor symptoms. Alpha - synuclein (aSyn) is the major ... -
BAF155 regulates the genesis of basal progenitors through both Pax6-dependent and independent mechanisms during cerebral cortex development
(2018-04-10)During mammalian development, the balance between symmetric and asymmetric division of radial glial (RG) progenitors regulates the tangential size versus radial growth of the cerebral cortex. The pool of basal progenitors ... -
Dlk1 Membrane-to-Nuclear Signalling During Motor Neuron Functional Diversification
(2017-11-20)Motor neurons of the spinal cord and hindbrain are responsible for translating neural commands into movements. For the execution of smooth movements, it is necessary that motor neuronal impulses are in turn translated into ... -
Systematic analysis of heterochromatin modification readout
(2017-06-14)Modifications of the building units of chromatin - the histone proteins and DNA - direct the functional readout of the genome and are part of the so called “epigenome” (Fischle et al., 2003b; Kouzarides, 2007). Several ... -
miRNAs in protection and regeneration of dopaminergic midbrain neurons
(2017-02-24)PD is the second most frequent neurodegenerative disorder affecting over 3 % of the population older than 80 years of age. Although PD is a system disorder which affects most regions of the brain, the progressive demise ... -
Neuronal correlates of implicit learning in the mammalian midbrain
(2016-08-29)Filtering auditory information according to its relevance is critical to elicit the appropriate behavioral response. The relevance of a sound is not carried by the sound itself but rather assigned by the brain based on ... -
Epigenetic Modulation in Alzheimer's Disease: Function of Hippocampal microRNAs
(2015-12-04)MicroRNAs (miRNA) are small non-coding RNAs that play a critical role in the regulation of gene expression programs and thus key mediators of cellular homeostasis. There is increasing evidence that deregulation of miRNAs ... -
The Role of Lysine Acetyltransferase Tip60 in the Murine Hippocampus
(2015-07-07)Making new memories is a highly complex process, which involves rapid modifications of existing proteins, induction of gene expression, de novo protein synthesis, and the altering of neuronal structures. The cellular ... -
AAV-based gene therapy for axonal regeneration in a rat model of rubrospinal tract lesion
(2015-04-29)Spinal cord injury (SCI) is a devastating and largely irreversible clinical condition, which can lead to permanent sensory and motor functional disabilities. Worldwide, an estimated 2.5 million people suffer from SCI and ...
