Since the earliest space missions, scientists have known that microgravity affects the immune system, putting astronauts at risk of infections and skin conditions.
They even had a theory about why those changes occur, although not how they could reverse them – until now.
The discovery, researchers say, has “huge implications” for our understanding of ageing, because the changes seen to cells in space are also observed as we get older.
“Our work provides a resource to better understand how and why the immune system changes in simulated microgravity and spaceflight,” said Prof Richard Furman, of Weill Cornell Medical College in New York.
“We also provide a way to develop countermeasures to maintain normal immunity under these harsh conditions.”
Researchers led by two scientists from the Buck Institute for Research on Ageing in California wanted to know more about why the changes occur.
They used blood immune cells which had been exposed to a process which simulates the space environment on Earth, combining them with data from space flight from astronauts and mice on the International Space Station.
“We show how simulated microgravity shapes immune cells and how the changes in force alter the cells’ function at the single cell level,” said author Dr Daniel Winer, from the Buck Institute.
“This level of resolution is new and exciting in understanding the effects of microgravity on cells.”
That helped researchers build a picture of how immune system cells like lymphocytes and monocytes are changed by reduced gravity – discovering effects that are also observed during the normal ageing process.
They also wanted to see if they could isolate any drugs or supplements that could protect the cells.
Using artificial intelligence to study more than two million interactions between genes, drugs and foods, the researchers identified dozens of possible compounds, pinpointing one with potential – a plant pigment called quercetin.
The compound, which is found in red onions, grapes, berries, apples and citrus fruits, among other foods, is known to have antioxidant properties.
Researchers tested it on the cells which had been exposed to the space environment, discovering that quercetin reversed approximately 70 per cent of the changes caused by lack of gravity.
“This is the first comprehensive study that provides the scientific community worldwide with an atlas to understand human biology in this extreme condition,” Dr Winer said.
“The implications are huge, beyond humans in space.”
Astronauts’ vulnerability to illness was first noticed in the Apollo missions in the 1960s and 1970s, when just over half of them became sick with colds or other illnesses within a week of their return.
Some of them even experienced the reactivation of dormant viruses, such as chickenpox, prompting researchers to start looking into why that might be.
Space studies
Saudi Arabia's Rayyanah Barnawi, a research scientist, conducted an investigation into human immune cells during a stint onboard the International Space Station last year.
She studied the inflammatory response of the cells in microgravity, including the changes in mRNA decay, a process that regulates gene expression changes in cells and can influence the effects of inflammation.
The ISS tests, which were carried out with the help of Emirati astronaut Sultan Al Neyadi, who is now Minister of State for Youth Affairs, and in parallel with experiments on the ground, to help scientists measure the difference in results.
Researchers hoped the results would better understand the immune system and develop potential therapies for inflammatory diseases in space and on Earth.
Last year, the European Space Agency started an experiment to understand how the body’s immune system was affected by the space environment.
Scientists took samples of astronaut Andreas Mogensen’s blood and saliva before, during and after his mission, which ended on his return to Earth on March 12 after more than 199 days in space.

Key figures in the life of the fort
Sheikh Dhiyab bin Isa (ruled 1761-1793) Built Qasr Al Hosn as a watchtower to guard over the only freshwater well on Abu Dhabi island.
Sheikh Shakhbut bin Dhiyab (ruled 1793-1816) Expanded the tower into a small fort and transferred his ruling place of residence from Liwa Oasis to the fort on the island.
Sheikh Tahnoon bin Shakhbut (ruled 1818-1833) Expanded Qasr Al Hosn further as Abu Dhabi grew from a small village of palm huts to a town of more than 5,000 inhabitants.
Sheikh Khalifa bin Shakhbut (ruled 1833-1845) Repaired and fortified the fort.
Sheikh Saeed bin Tahnoon (ruled 1845-1855) Turned Qasr Al Hosn into a strong two-storied structure.
Sheikh Zayed bin Khalifa (ruled 1855-1909) Expanded Qasr Al Hosn further to reflect the emirate's increasing prominence.
Sheikh Shakhbut bin Sultan (ruled 1928-1966) Renovated and enlarged Qasr Al Hosn, adding a decorative arch and two new villas.
Sheikh Zayed bin Sultan (ruled 1966-2004) Moved the royal residence to Al Manhal palace and kept his diwan at Qasr Al Hosn.

Anxiety and work stress major factors
Anxiety, work stress and social isolation are all factors in the recogised rise in mental health problems.
A study UAE Ministry of Health researchers published in the summer also cited struggles with weight and illnesses as major contributors.
Its authors analysed a dozen separate UAE studies between 2007 and 2017. Prevalence was often higher in university students, women and in people on low incomes.
One showed 28 per cent of female students at a Dubai university reported symptoms linked to depression. Another in Al Ain found 22.2 per cent of students had depressive symptoms - five times the global average.
It said the country has made strides to address mental health problems but said: “Our review highlights the overall prevalence of depressive symptoms and depression, which may long have been overlooked."
Prof Samir Al Adawi, of the department of behavioural medicine at Sultan Qaboos University in Oman, who was not involved in the study but is a recognised expert in the Gulf, said how mental health is discussed varies significantly between cultures and nationalities.
“The problem we have in the Gulf is the cross-cultural differences and how people articulate emotional distress," said Prof Al Adawi.
“Someone will say that I have physical complaints rather than emotional complaints. This is the major problem with any discussion around depression."

Which honey takes your fancy?
Al Ghaf Honey
The Al Ghaf tree is a local desert tree which bears the harsh summers with drought and high temperatures. From the rich flowers, bees that pollinate this tree can produce delicious red colour honey in June and July each year
Sidr Honey
The Sidr tree is an evergreen tree with long and strong forked branches. The blossom from this tree is called Yabyab, which provides rich food for bees to produce honey in October and November. This honey is the most expensive, but tastiest
Samar Honey
The Samar tree trunk, leaves and blossom contains Barm which is the secret of healing. You can enjoy the best types of honey from this tree every year in May and June. It is an historical witness to the life of the Emirati nation which represents the harsh desert and mountain environments

Tearful appearance
Chancellor Rachel Reeves set markets on edge as she appeared visibly distraught in parliament on Wednesday.
Legislative setbacks for the government have blown a new hole in the budgetary calculations at a time when the deficit is stubbornly large and the economy is struggling to grow.
She appeared with Keir Starmer on Thursday and the pair embraced, but he had failed to give her his backing as she cried a day earlier.
A spokesman said her upset demeanour was due to a personal matter.

Evacuations to France hit by controversy
- Over 500 Gazans have been evacuated to France since November 2023
- Evacuations were paused after a student already in France posted anti-Semitic content and was subsequently expelled to Qatar
- The Foreign Ministry launched a review to determine how authorities failed to detect the posts before her entry
- Artists and researchers fall under a programme called Pause that began in 2017
- It has benefited more than 700 people from 44 countries, including Syria, Turkey, Iran, and Sudan
- Since the start of the Gaza war, it has also included 45 Gazan beneficiaries
- Unlike students, they are allowed to bring their families to France
