Science Objectives for Everyone
Role of the Endocannabinoid System in human Lymphocytes Exposed to Microgravity (ROALD2) investigates the function of endocannabinoids, substances produced within the body to activate cell membrane receptors, in the regulation of the immune processes and cell cycle under microgravity conditions.

Previous ISS Missions
ROALD2 expands on the objectives of the ROALD experiment flown on ISS in 2008 (BIO-4 mission), using similar experiment protocol.
- Anandamide (AEA) is the main representative of a family of polyunsaturated fatty acid amides and esters, called endocannabinoids.
- This project aims at investigating gene expression of the proteins involved in the metabolic control of AEA tone, in order to determine the role of this lipid in the regulation of immune processes and in the cell cycle under microgravity conditions.
- In fact, AEA is a signal for the cells to make a choice between life and death and it might be a contributor responsible for the immune deficit observed in space.
