Systemic evaluation of immune cells and cytokines in patients with different clinical severity of Omicron infection
Abstract Immune cells and inflammatory cytokines play pivotal roles in immune response against viral infections. Herein, we performed a comprehensive immunocyte profiling to delineate the variations in immunocyte populations and cytokine levels among patients infected with Omicron presenting different clinical severities. Whole blood samples were collected from a cohort of 109 participants who sought medical assistance at Peking Union Medical College Hospital between December 2022 and February 2023 in China. Study …
