Why a given neuropathology does not impact all neurons of the same type to a similar level? This is a fascinating question in neurodegeneration research that remains unanswered.

In most neurodegenerative diseases certain neuronal subgroups degenerate fast while others, carrying the same mutations -if any-, subjected to theoretically analogous stress and displaying comparable functional properties remain unaffected, even at the latest stages of the disease. Motor neuron diseases are a group of disorders in which motor neurons (MNs) of the spinal cord and/or the motor cortex are the primary cell type affected where this perplexing feature can also be observed.

Using a variety of approaches ranging from cellular biology techniques and live imaging to genome editing and single cell genomics, and utilizing hiPSC together with transgenic animal models, we investigate the molecular mechanisms underlying such selective MN death. We devote a special focus at exploring the molecular basis of proteostasis failure -major causative event in neurodegeneration-, and at examining the contribution of cell autonomous and non-cell autonomous factors to the selective MN loss. Our ultimate goal is to understand the molecular cause of this distinctive neuronal vulnerability to design effective therapeutics targeting specific neuronal subtypes or phases of the disease.
