- Findings of a new study suggested that the immune systems of CovidD-19 positive people may rely on antibodies created during infections from earlier coronaviruses.
- The results suggest that the Covid-19 virus may awaken an antibody response that existed in humans prior to current pandemic, meaning that we might already have some degree of pre-existing immunity to this virus.
- The understanding of coronaviruses triggered immunity responses may help scientists design new diagnostics and future vaccines that may help in protecting people from mutations.
- The researchers employed a tool called PepSeq to map antibody responses to all human-infecting coronaviruses.
- PepSeq is a novel technology being developed at TGen and NAU that allows for the construction of highly diverse pools of peptides (short chains of amino acids) bound to DNA tags.
