Research. Lama’s antibodies, a new avenue in the fight against the coronavirus

The llamas’ immune system could neutralize the virus that causes Covid-19. The antibody, isolated by American and Belgian researchers, may be able to protect humans from the deadly disease.

Specifically, they can serve as an “anchor” for the virus, by attaching to another protein on the outside of a cell which it will then infect. Several recent studies demonstrate that in the case of Sars-CoV-2, these S proteins bind to human cell receptors with a force at least ten times greater than that of the S protein of Sras. “Data-reactid =” 21 ” > How does it work?

A very specific action

This is where the llamas’ antibodies come in. Indeed, the llamas’ immune system – and that of other camelids like alpacas – produces two types of antibodies when it detects pathogens, one that resembles human antibodies and another, more (…)
