Scientists at Boston University and the University of Pennsylvania have used patient-specific induced pluripotent stem cells (iPSCs) to model functional abnormalities of the highly specialized cells, called type-2 alveolar epithelial cells, that line the delicate air sacs of the lungs. The findings published in a Cell Reports paper, “Patient-specific iPSCs carrying an SFTPC mutation reveal the

The role of pre-existing immunity, specifically pre-existing T cells, in the course of a SARS-CoV-2 infection, remains unclear. New work adds clarity to this intensely debated area. The research shows that T-cell responses derived from immune system memory against the “common cold” coronaviruses enhanced SARS-CoV-2 immune responses after infection with SARS-CoV-2 and after vaccination with
