A new study led by scientists at UCSF's Quantitative Biosciences Institute and University College London found that the Alpha variant of SARS-CoV-2 ramped up production of a protein that it uses to stifle infected cells’ immune-stimulating signals, helping it evade immune detection and accelerate its transmission.
