A group of research scientists have discovered how a protein molecule promotes the production of nitric oxide inside the immune cells which in turn aids in the prevention of the body from the microbial attack. The protein is found to act as a target for restricting the inflammatory response thereby helping the immune system to fight against infection without causing any damage to the tissues.
