1_Prof. Lara Manganaro
Didactic Unit: Viral Vectors

This unit provides an in-depth exploration of viral gene transfer techniques and gene therapy. The main themes include:
Viral Replication and Gene Expression Strategies: Comprehensive study of in vivo and ex vivo gene therapy methodologies.
Characteristics and Applications of Vectors: Detailed examination of retroviral, lentiviral, adenoviral, and adeno-associated virus (AAV) vectors, highlighting their unique characteristics and uses.
Innate Immune Response: Analysis of the body's innate immune response to viral vectors.
Advanced Applications: Coverage of viral vector use in genetic editing, genetic vaccines, and oncolytic viruses.

2_Prof. Tommaso Pietro Fraccia
2 Didactic Unit: Physics

Inorganic nanoparticles (metallic, magnetic, semiconductors, quantum dots), physical properties as a function of scale, diffusion, and their use for imaging. Hyperthermia.
Physical principles for the description of the collective phase behavior of polymeric systems (phase separations, complex coacervation), self-assembly of molecules and biological macromolecules (lipids, nucleic acids, and peptides), and nanostructured biomaterials (DNA nanotechnology). Application examples for the development of organic nanoparticles for the transport and/or controlled release of drugs: liposomes, polymeric nanoparticles, polymeric micelles, polymersomes, dendrimers, polymer/lipid-nucleic acid complexes.
Techniques for the characterization of nanoparticles: electron microscopy (TEM, SEM), atomic force microscopy (AFM), dynamic light scattering (DLS), Z-potential, radiation scattering (neutrons, X-rays). Introduction to microfluidics and examples of lab-on-chip applications.
Nanoparticle-based biosensors (SPR, enhanced Raman scattering, fluorescence, light scattering).

3_Prof. Sergio Romeo
3 Didactic Unit: Chemistry of Nanoparticles

Introduction: properties of nanoparticles and pharmacokinetics, applications of nanoparticles in gene- and drug-delivery.
Inorganic particles: calcium sulfate, silica, gold, magnetic compounds, quantum dots. Carbon nanotubes, fullerenes, supramolecular systems.
Synthetic or natural biodegradable particles: cationic lipids, lipid nano emulsions, solid lipid nanoparticles, peptide-based nanoparticles.
Polymeric vectors: cationic polymers, natural proteins, peptides, polysaccharides, dendrimers, polyethylenimine (PEI).
Active and passive targeting: examples of site-specific release strategies, design of bioconjugates; vascular targeting; enzyme-mediated tissue selectivity; enzyme-prodrug therapies, central nervous system targeting.

Assessment methods and Criteria
The exam consists of 3 tests, one for each instructional unit. Viral Vectors Unit (3 CFU): written "multiple choice" test with one open-ended question. Physics Unit (2 CFU): oral exam. Chemistry Unit (2 CFU): oral exam.
The student should be able to present the acquired knowledge, as well as the ability to reason and integrate the topics covered in the lessons.
The final grade (out of thirty) will be calculated as the weighted average (based on the CFU) of the scores obtained in the individual instructional units.
