Specialized Pro-Resolving Mediators (SPMs) as Potential Covid-19 Therapeutic

April 21, 2022 Introduction  Our last Perspective described how the timing of the type 1 interferon (IFN) response is a critical early point in determining whether infection with SARS-CoV2 will lead to severe disease or not. IFN activity later in infection, when disease has already developed, is apparently ineffective, and is instead detrimental. Indeed, an…

Cell-Mediated and Innate Immunity Against SARS-CoV-2: What is Known

Cell-Mediated and Innate Immunity Against SARS-CoV-2: What is Known January 26, 2022 Titers of neutralizing antibodies (nAbs) against SARS-CoV-2 have proven a reasonable predictor of protection against infection and disease. However, T cell responses (CD8+ and CD4+), innate immune mechanisms, and Fc-mediated cellular cytotoxicity can also provide protective immunity against the virus. T cells The…
