This e-learning course will guide you through the essentials of optogenetics - an emerging field of research that provides novel resources to control a target protein’s function using light with high temporal and spatial precision. We will focus on applications of non-opsin derived proteins rather than classical methods used to control electrical activity in neurons.

Target audience

This course is for anyone who is interested in learning about concepts and applications of optogenetics, as well as practical guidance for your own experiments. An undergraduate level of understanding in biology would be an advantage.

Learning objectives

• Define what optogenetics is and how it can be used
• Evaluate some of the most widely-used optogenetics systems
• Apply the fundamental principles of setting up and running optogenetics experiments in your lab

Module 1: Principles and Approaches

This video will introduce you to the general concept of optogenetics and different strategies to optically regulate a target.

Duration: 5 mins

Module 2: Exploring Different Optogenetic Systems

We will introduce you to the most-commonly used optogenetic systems, based on light-induced dimerisation and photocaging. We will explain and compare different systems including the cryptochrome, phytochrome and LOV domain-based systems to reveal their specific advantages and limitations.

Get Started (Duration: 20 mins)

Module 3: Applications of Optogenetics at EMBL

We will take you through the steps and practical considerations when setting up an optogenetic experiment in your lab. As a case study, we will use the novel optogenetic system that the De Renzis lab at EMBL have developed to control cellular contractility in living fly embryos.
