Reviews

  • Review Article |

    The evolution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been characterized by the emergence of mutations and so-called variants of concern that impact virus characteristics, including transmissibility and antigenicity. In this Review, members of the COVID-19 Genomics UK (COG-UK) Consortium and colleagues summarize mutations of the SARS-CoV-2 spike protein, focusing on their impacts on antigenicity and contextualizing them in the protein structure, and discuss them in the context of observed mutation frequencies in global sequence datasets.

  • Review Article |

    In this Review, Schultz-Cherry, Thomas and colleagues discuss the pathogenesis of influenza virus and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the human respiratory tract, the contribution of the host response to severe disease, epithelial repair mechanisms following infection, and current and potential future therapies for influenza virus and SARS-CoV-2 infections.

    Cryptococcosis is a serious fungal infection for which treatment options are limited. In this Review, Cowen and colleagues discuss the current antifungal treatments available for cryptococcal infections, the challenges in developing new treatments, and ongoing efforts to identify novel therapies.

    Toxoplasmosis caused by the parasite Toxoplasma gondii is a common opportunistic infection with high mortality in individuals who are immunocompromised, most commonly due to reactivation of infection in the central nervous system (CNS). In this Review, Sibley and colleagues explore the interaction between host immune defences and parasite virulence factors with emphasis on bradyzoite differentiation and survival of T. gondii within the CNS.
