The following is a summary of some recent studies on COVID-19. They include research that warrants further study to corroborate the findings and that has yet to be certified by peer review.
Summary
- Once the body learns to recognize SARS-CoV-2, either after infection or vaccination, B cells generate fresh antibodies against the virus if there are not already enough antibodies circulating in the blood that can neutralize it.
- Memory B cells’ robust ability to proliferate and produce antibodies might compensate “in less than two days” for those antibodies’ reduced effectiveness, they speculate.
- Orf9b in turn disables a protein called TOM70 that cells use to send signals to the immune system.
- With higher levels of Orf9B disabling TOM70, the immune system does not respond as well and the virus can better evade detection, the researchers said.
- The same mutation was identified on Delta, “and sure enough, almost the same mutation is on Omicron,” he said, which suggests they may have similar effects on the immune system.
