New research shows leftover fragments from SARS-CoV-2 form protein pieces that bind to curved membranes on immune cells, suppressing dendritic cells and T cells and potentially driving long-COVID; Omicron fragments appear less damaging to these cells, highlighting variant differences while underscoring ongoing COVID risks and the value of vaccination.
Fragments of SARS-CoV-2 left behind after the immune system fights off infection may continue to trigger immune responses, leading to dangerous inflammation affecting various tissues and cell types. Researchers found that certain SARS-CoV-2 fragments, dubbed "xenoAMPs," resemble molecules that can bind to double-stranded RNA and trigger inflammation, potentially explaining the unusual aspects of COVID-19. These findings could lead to new strategies for treating severe cases of COVID-19 and shed light on how viruses can continue to affect the host even after being destroyed by the immune system.
