Stress would wake up the dormant virus ofherpesaccording to the results of a study published in the medical journal PLOS Pathogens.
Herpes is an infection caused by two types of virus, both highly contagious. Cold sores are related to the Herpes simplex virus type 1 (HSV-1). It is transmitted mainly through contact with the oral mucous membranes and causes cold sores.
Genital herpes is caused by the Herpes simplex virus type 2 (HSV-2). Incurable this virus is caught for the whole of his life. It is often asymptomatic and only detectable by a blood test.
Herpes risk factor stress
Researchers at the University of Helsinki (Finland) sought to understand the mechanisms of herpes activation. Scientists have observed a direct link between the cellular stress response, cell cycle regulation and virus reactivation.herpes.
Using advanced microscopy and genetic manipulation technologies, scientists have detected a wide variety of chemical compounds that cause the activation of a set of cellular stress sensor proteins that would reactivate the herpes virus.
“Deleting the infamous cellular stress sensor proteins restores cell division in cells and reduces viral gene expression. This suggests that the replication of the virus depends on the inhibition of cell division,” explain the researchers.
A virus that affects the whole world
The figures from the World Health Organization speak for themselves. This evil infects the whole world. More than 3.7 billion people under the age of 50, or 67% of the population, are infected with the herpes virus type 1 (HSV-1). 140 million people aged 15 to 49 have already had cold sores, according to WHO figures.
