Daylight helps the immune system fight infections

Scientists at the University of Oakland have found that the daylight can improve the ability to fight the immune system, the focus of the fact. The study was published in the magazine of Science Immunology (Sciim).

Scientists have focused on neutrophils, the largest number of immune cells, which are the first to respond to inflammation and destroys harmful bacteria and other pathogens. In order to observe their behavior, researchers have used a model organism, a transparent type of freshwater fish called the zebruk. Thanks to the possibility of imagining their genetic resemblance and biological processes with people in real time, these animals have become ideal tests.

According to the General Author of the study, Associate Professor Christopher Hall has been observed that the immune response is peaked in the morning at the beginning of the active phase of the body's life. According to the scientist, this may be due to an evolutionary mechanism. In the daytime, the probability of meeting with the pathogens is higher, and the body must be ready for it.

The new job has helped to identify that neutrophiles have their own policcase clock, an internal biological mechanism that is sensitive to day and night change. They activate cells with the effect of daylight and improve their ability to destroy bacteria.

"Because neutrophils are the first cells arriving in inflammation, our discovery can be of great importance to the treatment of inflammatory diseases," Hall said. Scientists hope that in the future these discoveries will help develop new treatments, which will be aimed at lifting immune protection through the regulation of zircut rhythms.
