People who have had dengue fever may develop some immunity to covid-19. This was announced by Reuters, citing a previously unpublished study by Professor Duke University Miguel Nicolelis.
The US researcher found that in regions where dengue epidemics have been reported in recent years, the spread of coronavirus is slower.
“This amazing discovery demonstrates an interesting potential for immunological cross-reactivity between the flavengirus dengue and SARS-CoV-2 serotypes,”
According to Nicolelis, if his assumption is confirmed, people will be able to get a certain level of immunity to covid-19 through vaccination against dengue fever.
In early September, we reported that researchers had discovered nanotypes that could effectively block the penetration of coronavirus Sars-CoV-2 into cells.
The results of the study were published in the journal Nature Communications.
Experts from the University of Carolina in Sweden applied an arrow-shaped protein to alpacalama, with the help of which coronavirus penetrates the body’s cells, and in 60 days her blood tests showed a strong immune response.
The researchers then cloned and examined the sequence of nanobodies from the animal’s B lymphocytes that were involved in antibody production.
The researchers discovered a type of Ty1 nanocouple that attaches to the parts of the arrow protein that bind to the ACE-2 receptor and, with increased efficiency, prevent the virus from entering the body’s cells.
The researchers said that the nanocrops discovered are much smaller than ordinary antibodies, easier and more cost-effective to produce, and that they can also be adapted by humans.
