Moderate alcohol use increases immunity

Medical science has long known that people who consume moderate amounts of alcohol have a reduced risk of mortality. They are not only healthy, but also note an improvement in the state of the cardiovascular system, compared to people who do not drink at all.

A new study conducted at Oregon Health & Science University showed that moderate drinking can actually strengthen our immune system and help it fight the infection.

The study, published in the journal Vaccine, not only reveals something new in the scientific understanding of the functioning of the immune system, but will also help scientists discover new improved ways of the human body's ability to respond to vaccination and infection.

Scientists conducted their studies on macaques, in which the immune system is very similar to the human. To conduct the study, the scientists trained a group of 12 macaques to voluntarily consume alcohol, which contains 4 percent of ethanol.

Scientists in the framework of the study carried out vaccination of monkeys against

smallpox. Then they divided the animals into two groups. The first group had access to 4 percent ethanol, the second - to sweet water. All animals had access to clean water and food.

Then the researchers observed daily how much ethanol was consumed by animals for 14 months. Seven months after the start of the experiment, primates were vaccinated again.

"Like people, macaques showed different behavior when drinking alcohol said Ilhememessaudi, the lead author of the article, a former associate professor of the Institute of Vaccination and Gene Therapy at OHSU. "Some animals drank large amounts of ethanol, while others - in moderation."

Volunteer ethanol monkeys were divided into two groups. One group consisted of strongly drinking monkeys that had an average ethanol concentration in the blood more, 8 ppm - the maximum permissible level for people, under which it is allowed to drive a vehicle (USA). The other group consisted of moderately drinkers, with an average concentration of ethanol in the blood from, 2 to, 4.

Moderate alcohol use increases immunity

Prior to drinking, all primates had relatively similar responses to vaccination. But after drinking alcohol, these two groups of monkeys had different responses to vaccination.

The scientists made an unexpected conclusion: monkeys who consumed a moderate amount of alcohol, noted an expanded response to vaccination, compared with the control group. They have strengthened the immune system, and the response to vaccination has decreased compared to the control group of monkeys, who drank sugar water.

Researchers stressed thatexcessive consumption of alcohol was harmful to the immune systemmonkeys, as well as for humans.
