BanLec - a lectin represents a protein which is able to bind to sugars. Banana lectin is able to suppress HIV infection, preventing the penetration of the virus into the body. According to scientists, BanLec affects the protein shell that surrounds the genetic material of the HIV virus.
However, the main problem of HIV consists in virus mutation making HIV virus resistant to drugs. According to the study the presence of lectins makes difficult for the viruses to mutate.
