scientists from China and USA discovered the molecular mechanism responsible for the death of bees in winter, opening up new possibilities for improving the health of this planet’s most important species.
The key is in sirtuin (SIRT1), a type of protein needed to regulate energy and immune system metabolism, whose function is altered by cold, the state-run Xinhua news agency reported today.
The study, published in the Journal of Advanced Research, is a collaborative effort between the Institute of Zoology of the Canton Academy of Sciences and the Belttsville Bee Research Laboratory, Maryland, in conjunction with the Agricultural Research Service, Department of Agriculture. USA.
scientists confirmed that sirtuin showed significant difficulty in regulation in bees exposed to low temperatures, for which, according to the study, they associated cold stress with a genetic change in said protein.
According to the study, in winter, bees increase their energy intake to keep the hive warm, thereby reducing the energy destined for their immune system.
This makes the bees more susceptible to disease during the cold months of the year, which leads to high mortality bee family in this age.
As a possible solution, the researchers point to the substance SRT1720, which, after genetic activation, will enhance the functioning of sirtuin and improve the human immune system. bees and, thereby, increase their life expectancy in the months of low temperatures.
“This discovery represents a promising approach to developing therapeutic strategies to facilitate the disappearance of colonies. bees” adds the article.
The scientific community has been warning for years of the serious consequences for the planet of global population decline. beesone of the largest pollinators with over 20,000 species.
