A new perspectives piece co-authored by Carnegie Mellon University and […]
How CD4+ T cells respond to SARS-CoV-2 in COVID-19 recovered patients
An international team of researchers from the Institute for Research in Biomedicine, affiliated to the Università della Svizzera italiana, has deciphered the T cell responses occurring during COVID-19 infection at single-cell resolution. This study, which was performed at the Center of Medical Immunology under the leadership of Prof. Federica Sallusto, included collaborations with clinical institutions […]
