While we have developed vaccines that provide a level of protection against SARS-CoV-2, the virus that leads to Covid 19, more recent strains such as Omicron have proved harder to stop, reported DW. Our immune systems produce antibodies naturally when they identify a virus in the body. Scientists used a “humanized” mouse model to search for new antibodies. The mice are “humanized” by injecting them with a solution that contains human gene segments, which cause their immune systems to work like ours do, and produce human-like antibodies. That is the theory, reported DW.
After “humanizing” the mice, the scientists exposed them to Covid. The mouse immune systems produced antibodies in response to the virus, and scientists were surprised to discover that one of the antibodies produced was able to neutralize (that is, stop) all known Covid strains, alpha, beta, gamma, delta and all subvariants of omicron, including BA.5. The new antibody, known as SP1-77, is different from other antibodies in that it stops a later step in infection, a point at which the virus “fuses” with cell membranes. “SP1-77 binds the spike protein at a site that so far has not been mutated in any variant,” said Dr. Tom Kirchhausen, one of the study authors, in a statement, reported DW. “These properties may contribute to its broad and potent activity.” The team of scientists said they had sought patents for the mouse model and SP1-77 to develop a vaccine. “More experiments are now needed to determine whether this monoclonal antibody can neutralize or kill different SARS-CoV-2 coronavirus variants and importantly, whether they also protect animals or humans against infection,” as reported by DW.
Watch against contagion
To this date and since September 8 251 new cases of contagion and 1 death caused by Covid 19 were reported by State and Health Authorities. Contagion is being watched in Guanajuato and cases of contagion reported are over 250 in the last 6 days, while there was 1 death reported. Authorities maintain the color of activities in the GREEN easing restrictions on activities, both leisure and work.
State Health Authorities insist that Guanajuato should maintain health protection.
