The "Cellular Physiopathology and Cancer" course aims to provide students with the knowledge necessary to follow the "Cancer Biology" program in M2. The course is organized in the form of a conference with an introductory section followed by a section on current research in laboratories. Students are required to give an oral presentation on a scientific article (usually in pairs).

The aim of the cellular pathophysiology and cancer teaching unit is to provide the scientific background necessary to follow the cancer biology M2 program. Each lecture is organized as a conference starting with a general introduction to the field and followed by a more specialized emphasis on research done in laboratories. Students have to prepare an oral presentation based on the analysis of a scientific article (generally in pairs).

Behaviors, whether determined by conscious or unconscious processes, are based on complex neurobiological substrates. They are underpinned by molecular and cellular changes within the nervous system that modulate the neural networks responsible for motor and emotional processes linked to an individual's memory. These processes are fundamental in enabling the organism to develop an integrated behavioral response in close interaction with its environment, thereby ensuring the adaptation and survival of the individual and their species.

The topics covered in the Behavioral Neurobiology course will be as follows:

-Gene–behavior

The relationship between genotype and phenotype -Impact of the environment –Attentional processes/Movement planning -Behavioral disorders (genetic and environmental aspects)

-Memory and synaptic plasticity

Methodological approaches to studying synaptic plasticity: electrophysiology, optogenetics, animal models, behavioral tests—Factors regulating synaptic plasticity, including genetic and epigenetic factors—The relationship between plasticity and memory—The neurobiology of memory, forgetting, and reconsolidation

The neuropsychopharmacology EU deals with the molecular, cellular, and integrated mechanisms underlying the mode of action of psychotropic drugs, using a few pathologies (depression, schizophrenia, anxiety, etc.) as examples. It aims to understand how the principles of pharmacology apply specifically to mental disorders (e.g., pharmacodynamics, tolerance, physical and psychological dependence, etc.). Based on advances in neurobiology research and their therapeutic applications in medication, the course aims to understand the concepts underlying the treatment of psychiatric disorders.

The EU will first address the main communication pathways between normal cells and intracellular transduction pathways encountered in physiological and neurophysiological mechanisms. Thus, G protein-coupled receptors (GPCRs) will be studied, namely their structure, function, and modulation by interaction proteins involved in particular in the phenomenon of desensitization. The main intracellular pathways activated by membrane GCRs will be addressed (MAP kinase pathways, PI3 kinase, etc.).

Next, a significant portion of the course will focus on calcium signaling and Ca2+ homeostasis, Ca2+ being a ubiquitous signal in cellular signaling. Calcium homeostasis will be studied in particular during the response of lymphocytes after antigen stimulation. Furthermore, the production of oxygen free radicals, which cause oxidative stress, is dependent on intracellular Ca2+. The physiological role of free radicals will be discussed, as well as their involvement in oxidative stress. In this context, the pathways of protection against oxidative stress will also be studied.The following chapter will address the endocannabinoid system, which will allow us to recap all the topics previously discussed in the course. The endocannabinoid system is responsible for multiple central and peripheral regulations.

Finally, two other topics will be addressed: the blood-brain barrier, which allows for highly integrated cellular communication between two environments, and the pancreatic β-cell, whose activity is crucial for regulating blood sugar levels through insulin secretion.

Teaching is carried out by lecturers and researchers from the medical, science, and pharmacy departments. It consists of 42 hours of lectures and supervised work divided into seven themes (see Syllabus), including two series of article presentations: the first series on articles proposed by the lecturers for each theme covered, and the second series on articles chosen by the students. Students organize a mini-symposium at the end of the course where the articles are presented. They write summaries of these articles for the journal Medecine-Sciences.
