    Studies have shown that the level of a protein called "chitinase 3-like protein 1" increases with age, as well as comorbidities and infections


    The corresponding author of the study, Dr.


    Chitinase 3-like protein 1 is a molecule that occurs naturally in the blood


    Researchers say that levels of chitinase 3-like protein 1 also show an increasing trend during normal aging


    In the experiment, the researchers used genetically modified model mice to study the relationship between chitinase 3-like protein 1 and ACE2, a key receptor for the new coronavirus to enter human cells


    Driven by this discovery, the researchers developed a humanized monoclonal antibody called FRG, which can attack a specific region of chitinase 3-like protein 1


    Researchers say the discovery paves the way for the development of treatments that protect people from infection


    At present, the research team is observing the response of these antibodies and small molecules to variants of the new coronavirus, including the recently popular delta variant
