Glucocorticoids, TNFis, and abatacept treatments negatively affect the longevity of humoral responses to SARS-CoV-2, including Omicron, after two vaccine doses. These findings may inform the timing of additional vaccination for AIRD patients.
Diabodies see the unseeable RAS oncogene mutations are common in various cancers, controlling their growth and survival. Targeting mutant RAS proteins with antibodies has been unsuccessful due to low surface expression, even when targeting mutant RAS peptides presented via HLA on the surface of cancer cells. Douglass et al. used phage display to generate single-chain variable fragments (scFvs) specific for mutant RAS peptide-HLA complexes. The authors tested various bispecific, T cell–engaging antibody formulations, finding that single-chain diabodies (scDbs) combining the aforementioned s...
