The aim of this lecture if to understand how cells react to their environment and to stimuli sensed via receptors and how they adequately respond to each of them
The lecture describes the different aspects of cell activation and of the signal transduction from a receptor which senses the external stimulus to the regulation of gene transcription. Several signaling pathways are described in details: G protein-coupled receptors with protein kinase A or protein kinase C activation ; growth factor receptor and MAP kinase activation ; insulin receptor and glucose uptake. These signaling pathways and cell responses will be placed in the context of pathological conditions. The last part is aimed to described the different types of cell death, notably apoptosis, and how they are regulated.

Oral examination. The classification mark is taking into account the evaluation of the pratical courses (4 out of 20) for the first session, but it is no longer the case for the second session.
The participation to the practical courses is mandatory and required to be allowed to present the exam.
