The researchers assessed the impact of mosquito bites on the human immune system
Scientists from Baylor College of medicine (USA) found that mosquito bites cause in humans a number of unusual immune reactions. The study is published in the journal PLOS Neglected Tropical Diseases.
The experiment was conducted on laboratory mice. Animals transplanted human stem cells, which later developed into the separate components of the human immune system. Then staff at the College has allowed four mosquitoes to bite freely a few rodents.
After that, in mice took blood samples and other tissues, six hours, day and one week after the experiment.
The researchers compared samples of indicators from intact rodents and found that the animals have bitten, the saliva of the mosquito has caused diverse and complicated reactions.
So, there was an intensification of cytokines — molecules responsible for the immune response. In addition, affected T-helper cells involved in antiviral and allergic reactions.
However, the consequences of mosquito bites were preserved to seven days and involves various body tissues, including blood, skin and bone marrow.
According to American experts, the survey may help to prevent the spread of various diseases.
Earlier, the French scientists were able to establish the exact date of the death of the leader of Nazi Germany of Adolf Hitler. Experts have found out that he died 30 April 1945.
