A recent study has identified microRNAs, which are part of the body’s in-cell defense mechanism against viruses, that target SARS-CoV-2.
The researchers also say that these decrease with age and certain health conditions. New research has identified the microRNAs that play a key role in combating SARS-CoV-2.
Scientists first discovered microRNAs in the mid-1990s. MicroRNAs are tiny fragments of RNA genetic sequence produced within the cells.
They play a role in fine-tuning how the body reads genetic code and turns it into protein. They usually switch off parts of the genetic code, but sometimes, they amplify it.
