Researchers discovered why some people never get Covid-19 through a novel immune response analysis

The study was led by the Wellcome Sanger Institute and University College London in the UK

Researchers analyzed genetic activity in nasal tissues and blood of people with unsuccessful SARS-CoV-2 infections

Sixteen unvaccinated volunteers were intentionally infected with a pre-Alpha strain under strict laboratory conditions

Single-cell RNA sequencing provided detailed timelines on hundreds of thousands of individual cells' activity

Three infection categories were identified: transient, sustained, and abortive, revealing the body's secret weapon

Volunteers with abortive infections showed faster immune reactions in nasal tissues, clearing the virus quickly

Elevated expression of the gene HLA-DQA2 in nasal cells was linked to mild infections

These findings highlight crucial early immune responses that either clear the virus or allow infection

Understanding these responses could help develop treatments and vaccines mimicking these natural protective mechanisms
