NewsResearchers develop lysosomal TRAP for clearance of viruses and variants
Researchers have developed a novel lysosomal strategy for clearing viruses and their variants. This lysosomal ‘TRAP’ (lysoTRAP) shows potential for inhibiting infection by viruses and variants in cell, mouse, hamster, and human lung organoid models.

NewsSeemingly ‘broken’ genes in coronaviruses may be essential for viral survival
Some coronaviruses, including Covid-19 have extra ‘accessory’ genes in addition to the usual minimal viral set and researchers have found that some of these viral genes have stuck around even though they don’t produce a working protein.
