Scientists Examine How the Immune System Responds to the Corona Virus


Scientists in Australia have identified and explained how the immune system is fighting against the corona virus. In the study, the development of white blood cells from a woman was monitored.

Researchers from the Peter Doherty Institute of Infection and Immunity, located in Melbourne, Australia, analyzed blood samples of a woman in her 40s at different times, showing mild to moderate corona virus symptoms.

The article, published in the journal Nature Medicine, said that the focus was on a 47-year-old woman who returned to Australia by visiting Wuhan 11 days before showing her virus symptoms. The woman complained of weakness, sore throat, dry cough, chest pain, shortness of breath and high fever.

The woman did not smoke and did not use any medication. The woman under observation was given fluid support through serums. Antibiotics, steroids or antiviral drugs were not added to the serum used.

The blood samples of the woman treated in this way could be used to map the immune system’s response to the virus. Dr. Oan Nguyen, one of the researchers of the study, said that the immune response to the corona virus was followed for the first time in this way.

Nguyen explained that they used the immune system responses information developed against the previously identified flu to track the patient’s immune system. The researcher stated that they saw an increase in the population of immune system cells developed against seasonal flu three days after the patient was admitted by the hospital.

Working with Professor Katherine Kedzierska, the University of Melbourne’s leading influenza immunology researcher, the researchers say that the immune responses to the virus should be examined to develop a vaccine against the corona virus.

Now scientists want to examine the immune responses of more serious cases of corona virus that result in death. Following these immune responses will reveal what is missing in the immune system against the virus.
