Researchers at ETH Zurich have identified a proteomic signature that could recognize long COVID six months after acute infection. Biologically, the signature indicated that the complement system remained active in patients with long COVID six months after infection. Translationally, it could lead to a diagnostic test for long COVID, and suggests that targeting the complement system could be a therapeutic approach to prevent or treat the disorder.
In a study published in Antiviral Research, researchers from the Max Planck Institute for Multidisciplinary Sciences and collaborators have presented optimized nanobodies targeting the receptor binding domain (RBD) of the SARS-CoV-2 spike protein.
The Nobel Prize-winning modification that prevents the innate immune system from recognizing injected mRNA as foreign and blocking transcription of the protein it encodes has been found on some occasions to cause ribosomal frameshifting.
