News Picture: Could a COVID Infection Help You Ward Off the Common Cold?

MONDAY, Might 9, 2022 (HealthDay Information)

In the event you get contaminated with COVID-19, there could also be a sliver of a silver lining: COVID could assist shield you in opposition to the common cold, researchers say.

The SARS-CoV-2 virus that causes COVID-19 belongs to a big and numerous household of coronaviruses that embody common cold viruses.

As a result of viruses on this household have comparatively comparable spike proteins, immune system antibodies in opposition to one coronavirus spike protein may doubtlessly additionally acknowledge comparable spike proteins in different coronaviruses. This implies that earlier publicity to SARS-CoV-2 may assist shield in opposition to different coronaviruses, together with people who trigger colds, in line with scientists on the Scripps Analysis Institute in La Jolla, Calif.

To seek out out if that is true, they took blood samples from 11 folks to search for serum antibodies — proteins that assist battle off an infection. Eight of the samples have been collected earlier than the COVID-19 pandemic whereas three have been from individuals who just lately had COVID.

“The tip objective of this could be to rationally design vaccines that may acknowledge many alternative coronaviruses,” stated examine co-author Sandhya Bangaru, a postdoctoral analysis affiliate.

The researchers examined how the samples reacted to remoted spike proteins from totally different coronaviruses: OC43 and HKU1, each related to frequent colds; SARS-CoV-2; SARS-CoV-1, which causes severe acute respiratory syndrome (SARS); and MERS-CoV, which causes Middle East respiratory syndrome (MERS).

Solely serum antibodies from COVID-19 sufferers reacted to the SARS-CoV-2 spike proteins, and so they additionally reacted extra strongly than pre-pandemic samples of antibodies to the spike proteins of the common cold viruses and the opposite coronaviruses, in line with the examine. The outcomes have been revealed on-line within the journal Science Advances.

“Most individuals have this baseline immunity to frequent coronaviruses, and publicity to SARS-CoV-2 will increase the degrees of those antibodies,” Bangaru stated in an institute information launch.

Research co-author Andrew Ward, a professor of integrative structural and computational biology, stated this examine may assist result in higher vaccines.

“Getting a greater understanding of how immunity in opposition to this broad household of coronaviruses modifications with COVID-19 an infection is a vital step towards creating higher coronavirus vaccines, each for COVID-19 and for future, associated pathogens,” Ward stated within the launch.
