Severe coronavirus disease 2019 (COVID-19) is characterized by pneumonia, lymphopenia, exhausted lymphocytes and a cytokine storm. Significant antibody production is observed; however, whether this is protective or pathogenic remains to be determined. Defining the immunopathological changes in patients with COVID-19 provides potential targets for drug discovery and is important for clinical management. In the short time since SARS-CoV2 emerged, much has been learned about the immunopathology of the infection. Here, Xuetao Cao discusses what these early insights imply for drug discovery and clinical management.
