For more than two years since the coronavirus appeared and with the massive spread in the world, there is a doubt that more than one person has asked: “Why are there some who, regardless of whether they take care of themselves or not, have not infected?”
It is an issue that has attracted attention. Well, on more than one occasion, in neighborhoods or neighborhoods, there have been situations of individuals who have not paid attention to the COVID-19 pandemic and continued to lead their lives as if there were no health crisis.
They did not suffer the consequences of the disease, while other people who followed the advice of the authorities and specialists, such as a healthy distance, staying at home as much as possible, applying antibacterial gel and wearing masks, ended up getting infected and, in the worst of cases, cases, they lost their lives.
Now, a study by the Humanitas Institute and the San Raffaele Hospital in Milan revealed that there is innate immunity to SARS-CoV-2, responsible for COVID-19.
The discovery of this mechanism of the organism might clear up doubts regarding the contagion of some people repeatedly, while others are not affected by the virus.
In addition, it can help prevent and combat the disease, which has turned humanity upside down for more than two years.
The work “Recognition and inhibition of SARS-CoV-2 by humoral innate immunity pattern recognition molecules”, which was published in the journal Nature Immunology, maintains that innate immunity includes various molecules with functions similar to those of antibodies, of which some serve as biomarkers of the severity of coronavirus disease.
The Mannose Binding Lectin (MBL) molecule, which has functions similar to those of antibodies, binds to the “spike” or “spicule” protein of the coronavirus and blocks its entry into the body; that is, it neutralizes it.
According to the creators of the analysis, this molecule is part of the “predecessors” of the antibodies and in its interaction with SARS-CoV-2 it is capable of blocking it, regardless of the variant in question, be it Omicron or Delta.
Now it’s time to study if it can be an indicator that helps specialists to treat or prevent the disease.
