Genetics as from the previous first level degree of the admitted students.

Good knowledge and education about anatomical and functional organization of the central nervous system is required.

Classroom lectures, seminars, laboratory findings discussion.

“NeuroGenetics and NeuroGenomics” (Prof. Giovannoni)

The “NeuroGenetics and NeuroGenomics” part of the “Neurogenomics” course will focus on the functional and molecular analyses of the genes' and genome's work with regards to those elements and technologies relevant for neuronal physiology and pathology.

The following topics will be discussed by means of classroom lectures and seminars as well as interpretation and discussion of laboratory findings with the students:

• Genetics and genomics in neuroscience: introduction, field of applications and perspectives in the context of neurology and neurosciences.
• Chromatin dynamics, transcriptional control, translational feedback loop and epigenetics in the circadian rhythm regulation (and viceversa)
• Gene networks at the basis of evolution of speech and language
• From the "monogenic disease" concept to the multi-gene and genome contribution in hereditary neurodegenerative disorders, the case of triplet repeat expansion diseases: molecular mechanism of mutation and its effects on the disease course; contribution of other genes in the genome in the disease onset and progression; molecular genetics of the “non-cell autonomous effect” in triplet repeat expansion disorders and the molecular role of glia in the pathogenesis and disease progression
• The molecular complexity of CNS cancer, how the genetics and the genomics contribute to the definition of cells, mutations heterogeneity, drug resistance and tumor evolution: cues from single cell genetic and genomics analyses in brain cancer
• Genetic tools for studying functions and dysfuctions of the central nervous From recombinase mediated genetic editing (i.e. BRAINBOW) to CRISPR/Cas9 technique (i.e. ORANGE technology). 

“Physiopathology and treatments of CNS genetic diseases” (Dr. Strettoi)

The “Physiopathology and treatments of CNS genetic diseases” part of the “Neurogenomics” course will focus on various diseases of the CNS with underlying genetic defects to illustrate genotype-phenotype correlations and experimental and clinical stage approaches to improve the disease outcome. The visual system will be often used as a paradigm to illustrate concepts and tools to which other genetic diseases of the CNS will be compared to obtain general notions. Lectures involving specific CNS areas (i.e. the callosal body; motor areas pertinent to the mirror system; etc.) will be introduced by summaries of the main anatomical organization, relevant morphological features, basic nomenclature and position in the brain as well as fundamentals of physiology. Indications for usage of web-based tools to navigate the brain will be provided. Various topics will comprise an experimental part illustrating modern methodological tools for the study of the CNS. Navigation and search of clinicaltrials.gov for the genetic diseases under study will be performed.

Specifically:

1. General anatomy of the Fundamental nomenclature. Inherited photoreceptor degenerations. From mutations to phenotype: known and (many) unknown cellular pathways to photoreceptor death starting from hundreds of mutations in 66 different genes. Retinitis Pigmentosa.

Examples of rare genetic patients of a given pathology (i.e. Parkinson’s disease) as guidance for the discovery of the mechanisms of these diseases.
6. Protein targeting in neurodegenerative diseases by antibody design and The case of Alzheimer, alpha-beta amyloid accumulation and employment of conformational specific antibodies. In vivo targeting of intracellular organelles. The immune response in the CNS as a limiting factor for drug (or viral vectors; or protein;) delivery.
