Hyperactivation of the complement system has been implicated in the pathology of COVID-19. Here the authors bring together the latest information on the role of complement in COVID-19 and progress in targeting complement components for treatment of severe disease.
Individuals with asymptomatic COVID-19 can transmit the virus and may be at risk of long-term disease. In this Progress article, Boyton and Altman present current insights into immune responses in asymptomatic SARS-CoV-2 infection and discuss the relevance of asymptomatic disease for public health strategies.
This Progress article provides an update on the COVID-19 vaccine effort in the light of ongoing vaccine efficacy studies and real-world data on vaccine effectiveness, including the impact of virus variants of concern and challenges for global deployment.
This Progress article brings us up to date on the role of inflammasomes in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and COVID-19, describing how they may be activated during infection and contribute to the overexuberant inflammatory response in severe disease, and the efforts being taken to target them therapeutically.
This Progress article summarizes our current understanding of the immune mechanisms of protection induced by the available COVID-19 vaccines. The authors compare vaccine-induced antibody responses following one or two doses of different vaccines and consider the relative importance of neutralizing antibodies for vaccine-mediated protection against SARS-CoV-2.
