Membrane protein dynamics is of great importance for living organisms. The precise localization of proteins composing a synapse on the membrane facing a nerve terminus is essential for proper functioning of the nervous system. In muscle fibers, the nicotin ...

Neuronal theories of neurodevelopmental disorders (NDDs) of autism and mental retardation propose that abnormal connectivity underlies deficits in attentional processing. We tested this theory by studying unitary synaptic connections between layer 5 pyrami ...

Magnetic resonance spectroscopy (MRS) allows measurement of neurotransmitter concentrations within a region of interest in the brain. Inter-individual variation in MRS-measured GABA levels have been related to variation in task performance in a number of r ...

In this thesis, I show the ability of engineered bivalent ligands to control HER signaling by taking advantage of the dimerization-dependent mechanism of the four different receptors in the HER (EGFR) family. While monovalent wild-type ligands form HER hom ...
The maturation of glutamatergic synapses in the CNS is regulated by NMDA receptors (NMDARs) that gradually change from a GluN2B- to a GluN2A-dominated subunit composition during postnatal development. Here we show that NMDARs control the activity of the sm ...
Peripuberty, comprising childhood and adolescence, constitutes an important time window in the brain development and maturation. Exposure to prolonged stress during this period has been shown to increase the risk for the development of psychopathologies la ...
Cell surface receptors allowthe cell to sense and respond to external signals. Receptor malfunctions are associated with many diseases. The diffusional behavior of receptors is of particular interest to understand how the cell modulates receptor function i ...
Schizophrenia pathophysiology implies both abnormal redox control and dysconnectivity of the prefrontal cortex, partly related to oligodendrocyte and myelin impairments. As oligodendrocytes are highly vulnerable to altered redox state, we investigated the ...

Excitatory synaptic transmission is accompanied by a local surge in interstitial lactate that occurs despite adequate oxygen availability, a puzzling phenomenon termed aerobic glycolysis. In addition to its role as an energy substrate, recent studies have ...

Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene cause late-onset, autosomal dominant Parkinson's disease (PD). The clinical and neurochemical features of LRRK2-linked PD are similar to idiopathic disease although neuropathology is somewhat heter ...
