The latest research finds that the human immune system is completely open to defense in space.
Release date: 2017-09-29 In order to clarify the impact of the space environment on the human body, scientists have recently conducted a study to analyze the protein components of blood samples from 18 Russian astronauts who have performed long-term missions on the International Space Station. Previous studies have long found that the space environment affects the body's metabolism, heat regulation, heart rhythm, muscle tone, respiratory system and other physiological indicators, but the mechanism at the microscopic level is still unclear. The Kelly brothers in the United States are identical twins and are all astronauts in order to observe the impact of the space environment on the human body. One of them flew to space and stayed for 340 days. After returning, he compared with his brother to observe the changes in the human body in the space environment. On September 28th, it is not surprising that long-term space travel may have an impact on the human body. But what is the mechanism of this effect at the molecular level? This has long been unclear. In order to clarify the answer to this question, scientists recently conducted a study on the protein components of 18 Russian astronaut blood samples that have been on the International Space Station for a long time. . The results show that the long-term space environment makes the body's immune system "open all possible defense mechanisms" in the face of unfamiliar threats, which leads to many changes in the human body, from organs to tissues to cells. Studies beginning in the middle of the 20th century have long found that the space environment affects the body's metabolism, heat regulation, heart rhythm, muscle tone, respiratory system and other physiological indicators, but the mechanism at the microscopic level is still unclear. Researchers in Russia and Canada have decided to analyze the protein components in astronauts' blood samples because proteins play an important role in the body's environmental adaptation mechanisms. With the help of the mass spectrometer, the research team collected the concentration of 125 proteins in the blood samples of 18 Russian astronauts. The blood samples were collected by taking blood 30 days before they were launched, and immediately after returning to Earth. After the last 7 days of repair, the blood was finally collected. This approach allowed them to observe fluctuations in the protein content of the astronauts' blood during this period and to observe how long it takes for the body to re-adjust the indicators back to their original levels. Professor Evgeny Nikolaev, who is a member of the Skolkovo Institute of Technology in Russia and the Moscow Institute of Physics and Technology, said: "For this study, we collected a series of proteins - non-infectious diseases. Biomarkers. The results of the analysis show that in the weightless environment, the human immune system responds similarly to the human body's post-infection response, because the human body is not sure how to face this unfamiliar environment, thus opening up all possibilities. Defense system." The researchers found that certain types of proteins remained stable throughout the process, while other protein levels changed, but quickly returned to normal, but some protein levels were slower to recover. At present, the major space agencies in the world are actively planning for a longer-term deep-space manned flight plan. At this moment, it is crucial to deepen the possible impact on long-term space travel to the human body. The results of this study show that the human body does not seem to There is a corresponding mechanism to deal with space flight, so we must try our best to adapt. Next, the research team intends to continue to conduct in-depth analysis and conduct research on more specific proteins in order to understand the deeper mechanisms behind it. Professor Nikolaev pointed out: "In this study, we used quantitative proteomics to analyze astronaut blood samples, so we can not only detect the presence of proteins, but also their concentrations." He said: "We will use this method to analyze more different types of proteins in the future and observe their correspondence with the human body's adaptation to the space environment. In order to better carry out research, the future plans to let astronauts Blood sampling analysis during space missions."
