Abstract: The present disclosure, in part, relates to novel, relates to novel, prognostic tools for severe COVID-19 disease, including identification of a set of clinical parameters that can be used to generate a clinical risk score of COVID-19 complications. The present disclosure also relates to proteomic panel-profiling of patients with severe COVID-19 complications versus mild-moderate symptoms to characterize biological processes and pathways associated with disease severity. Also disclosed are identified molecular changes associated with the clinical findings that can be used to generate a molecular severity score. In addition, the methods disclosed here relate to identifying effective methods of treatments based on the patient analysis.

Abstract: The present invention relates to variable domains of camelid heavy-chain antibodies (VHH domains) directed against the human CD3? component of the T cell receptor and specifically to methods of use of said polypeptides for delivering prophylactic, therapeutic or diagnostic compounds to human T lymphocytes. It further describes a novel one-step method for the identification of phage displayed camel monoclonal antibodies.
