The Dhaka Times Desk Not just a day or two, but for millions of years, there are remnants of an ancient virus lying dormant in the DNA of the human body, which scientists believe helps the body fight cancer.
According to a study by the Francis Crick Institute, dormant remnants of this old virus are waking up just as cancer cells are spreading in the body. - BBC news.
It also helps the body's immune system to subconsciously target and attack tumors.
The research team also wants to use this invention in the development of vaccines for current cancer treatment or prevention.
In the study, they also found a link between recovery from lung cancer and a part of the immune system called B-cells that cluster around tumors.
B-cells are a part of the body that make antibodies. It is particularly known for its role in fighting infections like Covid.
Basically what they do in lung cancer is a mystery. However, many tests on human and animal samples have shown that they are still ready to fight the virus.
These latent retroviruses also help reduce the levels of virus that antibodies are recognizing,”
Retroviruses also have a trick to keep copies of their own genetic instructions inside them.
More than 8 percent of what we think of as human DNA is actually the source of such viruses.
Professor Julian Downward, Associate Research Director of the Francis Crick Institute, said, "Some retroviruses became fixtures of the genetic code billions of years ago and contain things related to our evolution."
He also says that other retroviruses may have entered our DNA thousands of years ago.
He also said that over time external instructions have been co-opted and acted upon within the cells of the body. But others have strongly restricted its spread.
Cancer cells can go haywire when they get out of control and when old viruses are completely out of control.
Ancient genetic instructions also cannot regenerate new viruses, but they can fragment viruses. That is thought to be sufficient for the immune system to identify viral threats or disease threats within the body.
Things to do to prevent Corona virus
# try to stay at home all the time.
# Follow the rules and use mask when going out for emergency.
# three-layer cloth mask can be washed if desired.
# wash clothes after coming home from outside. Or hang it without shaking for at least four hours.
# Wash hands thoroughly (for at least 20 seconds) with soap or liquid before coming outside.
# plastic PPE or eyes, face, head must be washed thoroughly with detergent and dried after one use.
# Wear PPE made of cloth or clean as described.
# Use a head cap that completely covers the hair.
# Those who have sneeze cough should follow all the rules promulgated by the government. Also, wash hands as directed before and after handling food items, keys, switches, mice, remote controls, mobiles, watches, computer desks, TVs, etc. and after using the bathroom. Those who have dry hands use Moisture after washing their hands. Soap or hand liquid can be used. Why can this virus remain in the crackle (cracked part) of dry hands? Avoid using highly alkaline soaps or detergents.
