Empowering the NSC-34 cell line as a motor neuron model: cytosine arabinoside's action.

The NSC-34 cell line is a widely recognized motor neuron model and various neuronal differentiation protocols have been exploited. Under previously reported experimental conditions, only part of the cells resemble differentiated neurons; however, they do not exhibit extensive and time-prolonged neuritogenesis, and maintain their duplication capacity in culture. The aim of the present work was to facilitate long-term and more homogeneous neuronal differentiation in motor neuron-like NSC-34 cells.

Theater as a means of communicating research on climate change: The case of "Cambiare il clima".

Between 2018 and 2023, the Department of Environmental, Land and Infrastructure Engineering (DIATI) at the Polytechnic University of Turin (PoliTo) implemented a project to advance research and education on climate change monitoring, adaptation and mitigation solutions. As part of their communication efforts, DIATI partnered with Faber Teater to create the play "Cambiare il clima" (in Italian, this means "Change the Climate"). This involved a collaboration between DIATI researchers, communication officers, and Faber Teater.

A Closer Look at Histamine in .

The present work intends to provide a closer look at histamine in . This choice is motivated firstly because has proven over the years to be a very simple, but powerful, model organism abundantly assisting scientists in explaining not only normal functions, but also derangements that occur in higher organisms, not excluding humans. Secondly, because histamine has been demonstrated to be a pleiotropic master molecule in pharmacology and immunology, with increasingly recognized roles also in the nervous system.

Pan-neuronal expression of human mutant SOD1 in Drosophila impairs survival and motor performance, induces early neuroinflammation and chromosome aberrations.

Several mutations in the SOD1 gene encoding for the antioxidant enzyme Superoxide Dismutase 1, are associated with amyotrophic lateral sclerosis, a rare and devastating disease characterized by motor neuron degeneration and patients' death within 2-5 years from diagnosis. Motor neuron loss and related symptomatology manifest mostly in adult life and, to date, there is still a gap of knowledge on the precise cellular and molecular events preceding neurodegeneration. To deepen our awareness of the early phases of the disease, we leveraged two Drosophila melanogaster models pan-neuronally expressing either the mutation A4V or G85R of the human gene SOD1 (hSOD1 or hSOD1).

Frataxin deficiency shifts metabolism to promote reactive microglia via glucose catabolism.

Immunometabolism investigates the intricate relationship between the immune system and cellular metabolism. This study delves into the consequences of mitochondrial frataxin (FXN) depletion, the primary cause of Friedreich's ataxia (FRDA), a debilitating neurodegenerative condition characterized by impaired coordination and muscle control. By using single-cell RNA sequencing, we have identified distinct cellular clusters within the cerebellum of an FRDA mouse model, emphasizing a significant loss in the homeostatic response of microglial cells lacking FXN.
