CELLULAR VESICULES AND MOLECULAR NANOBIOTECHNOLOGIES
Academic Year 2022/2023 - Teacher: NUNZIO IRACIExpected Learning Outcomes
The optional course "CELLULAR VESICLES AND MOLECULAR NANOTECHNOLOGIES" aims at providing the student with an integrated view of how organelles are organized in the cytoplasm and how they interact with each other from a structural and functional point of view. Another objective is to introduce the student to the most recent discoveries about the role of extracellular vesicles, in particular exosomes, in the context of cell-to-cell communication and nanotechnologies.
The student will learn the fundamental techniques for the study of membranes and organelles, such as lipidomics and fractionation by ultracentrifugation and sucrose gradient. Ultimately, the student will be able to acquire a '3D vision' of the cell, and of the molecular dynamics of vesicle-mediated signaling, both within the cell and with the microenvironment.
Course Structure
Lectures and exercises.
Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.
Learning assessment may also be carried out on line, should the conditions require it.
Information for students with disabilities and / or SLD: To guarantee equal opportunities and in compliance with the laws in force, interested students can ask for a personal interview in order to plan any compensatory and / or dispensatory measures, based on the teaching objectives and specifications needs. It is also possible to contact the CInAP contact person (Center for Active and Participatory Integration - Services for Disabilities and / or SLD) of the Department of Biomedical and Biotechonological Sciences.
