In the study, mice who took water containing 10% alcohol had a decreased risk of rheumatoid arthritis.
Although, the team said they could not determine what amount of alcohol would have the same effect on humans.
It has been shown that low or moderate intake of alcohol can give various benefits including the risk of heart disease.
The researchers say alcohol could increase the male hormone testosterone and restrict a key part of the mechanism that releases the proteins cytokines which causes inflammation.
Professor Andrzej Tarkowski, who led the research, said: "We can't translate these results to find out the therapeutic dose in humans."
"The mice were given a dose of 10% of alcohol in their water, but we don't know if it would be the same for humans. It would probably be lower."
