    Divergent adaptive immune responses define two types of Long COVID, 2023, Chakrabarti et al

    The role of adaptive immune responses in long COVID remains poorly understood, with contrasting hypotheses suggesting either an insufficient antiviral response or an excessive immune response associated with inflammatory damage. To address this issue, we set to characterize humoral and CD4+ T...

    Long COVID manifests with T cell dysregulation, inflammation, and an uncoordinated adaptive immune response to SARS-CoV-2 2023 Yin et al

    Abstract Long COVID (LC), a type of post-acute sequelae of SARS-CoV-2 infection (PASC), occurs after at least 10% of SARS-CoV-2 infections, yet its etiology remains poorly understood. Here, we used multiple omics assays (CyTOF, RNAseq, Olink) and serology to deeply characterize both global and...

    Evidence of previous SARS-CoV-2 infection in seronegative patients with long COVID, 2022, Krishna et al

    Summary Background There is currently no consensus on the diagnosis, definition, symptoms, or duration of COVID-19 illness. The diagnostic complexity of Long COVID is compounded in many patients who were or might have been infected with SARS-CoV-2 but not tested during the acute illness and/or...

    Pre-existing polymerase-specific T cells expand in abortive seronegative SARS-CoV-2, 2021, Leo Swadling et al

    Pre-existing polymerase-specific T cells expand in abortive seronegative SARS-CoV-2 Leo Swadling, et al. Individuals with potential exposure to SARS-CoV-2 do not necessarily develop PCR or antibody positivity, suggesting some may clear sub-clinical infection before seroconversion. T-cells...
