Can the human body get rid and/or control its own immune system?
Can we all get rid, or control our own immune systems?
The answer to those questions and more is a little bit of a hiccup.
A new study, which will be published in the March issue of The Lancet Neurology, will answer these questions.
The researchers examined how different levels of oxygen, a key component of the respiratory and immune systems, were affected by the different oxygen concentrations.
The oxygen-deficient subjects were unable to produce sufficient amounts of CO 2 and could only breathe air with lower levels of CO2.
The CO 2-defective subjects had more oxygen in their bodies, but the level was much lower than that of the oxygen-deprived.
The results of the study, published in PLOS ONE, showed that oxygen deprivation led to lower levels and lower levels higher levels of respiratory distress.
The study was carried out by researchers at the University of Exeter, the University Hospital of Salford and the University Hospitals of Manchester.
The authors are now working on a study to find out whether oxygen deprivation affects the levels of cytokines, molecules that are produced in the body, and the effects of that cytokine on the human immune system.
“There is a lot of confusion about how oxygen is produced in humans and how it affects the immune system,” said lead author Dr. Jeroen De Meijers, professor of psychiatry at the university.
“What we were looking at was how oxygen affects the level of cytokine production in the lungs and the level in the blood.
In other words, what cytokines do the body produce?”
“We wanted to understand if oxygen deprivation could cause the immune cells in the lung to be more sensitive to cytokines,” Dr. De Meijners added.
The research team recruited 30 healthy volunteers who were either exposed to a low-oxygen environment, or in the absence of oxygen.
The volunteers were randomly assigned to a control group or a high-oxymedialogic group.
The control group was given a standard dose of oxygen and the high- oxygen group received a low dose.
They then took blood samples over a two-week period, one week after the first sample.
Then the volunteers took a blood sample for two days, followed by a blood test for cytokine levels.
After the blood samples were taken, the subjects were divided into groups of six and six were allowed to remain oxygen-fed.
The team also looked at how oxygen deprivation affected the cytokine-producing immune cells.
After a week of oxygen deprivation, the cytokines levels were found to be lower in the high oxygen group than in the low oxygen group.
“We were very surprised by this,” said Dr. Keirsen.
The participants who had been air-fed had a significantly lower number of cytokINE-producing cells in their blood, compared to the control group. “
So we had no idea what was happening,” he said.
The participants who had been air-fed had a significantly lower number of cytokINE-producing cells in their blood, compared to the control group.
But, the group of subjects that had not been oxygen fed had the same cytokine level in their body.
This meant that they were producing more cytokines.
The cytokine response to oxygen deprivation also differed among the groups.
The high oxygen groups had a lower cytokine concentration in their bloodstream than the low- oxygen groups.
This suggests that the high levels of the cytokin-producing blood cells in oxygen-free conditions may have been a result of the reduced oxygen supply in the oxygen deprivation group.
And, the results of these blood samples indicated that the cytokined cells were not affected by oxygen deprivation.
Dr. Robert Schumacher, a professor at the Medical University of South Africa who has worked with Dr. Reijnen, said that the study could help scientists understand the mechanisms behind the effects oxygen deprivation has on the immune systems.
“It shows that a group of people who have never been exposed to oxygen are having a more severe immune response,” he told The Associated Press.
“That suggests that they may have a genetic predisposition that predisposes them to an allergic reaction to oxygen.”
“This is something we will probably never understand completely,” Dr Schumachers added.
“But I think it provides some evidence of the immune response to hypoxia in humans, in this case a relatively small group of individuals.”
Dr. Schumakers group has been studying the immune responses to hypoxic conditions, but he said the new study provides a better understanding of the mechanisms underlying how oxygen and inflammation can cause different kinds of immune response.
He added that the new results should be of interest to anyone interested in the immune-mediated response to infection, which may involve an imbalance in the levels
