Immune response pattern across the asymptomatic, symptomatic and convalescent periods of COVID-19

ABSTRACT: We present an integrated analysis of urine and serum proteomics and clinical measurements in asymptomatic, mild/moderate, severe and convalescent cases of COVID-19. We identify the pattern of variation of immune response proteins during COVID-19 infection. The immune response is activated in asymptomatic infection, but is dysregulated in mild and severe COVID-19 patients. Our data suggest that the turning point depends on the function of myeloid cells and neutrophils. In addition, immune defects persist into the recovery stage, until 12 months after diagnosis. Moreover, disorders of cholesterol metabolism span the entire progression of the disease, starting from asymptomatic infection and lasting to recovery. Our data suggest that prolonged dysregulation of the immune response and cholesterol metabolism might be the pivotal causative agent of long-lasting disorders in blood coagulation and cardiopathy. Our study provides a comprehensive understanding of COVID-19 pathogenesis, which is instructive for the development of early intervention strategies to ameliorate complex disease sequelae.
