Cytokine Signatures and Immune Dysregulation in COVID-19 Patients: Transcriptomic and Serum Analysis.
COVID-19, caused by the SARS-CoV-2 virus, has caused a global health crisis, necessitating a deeper understanding of its pathophysiology. In this study, we explored the immune and hematological dynamics in COVID-19 patients to gain insights into disease severity and prognosis. Our findings revealed distinct cytokine profiles in moderate and severe cases. IL12A was significantly upregulated in peripheral blood mononuclear cells from moderate cases, suggesting a potential role in initiating an effective immune response. Conversely, severe cases exhibited downregulation of key pro-inflammatory cytokines (IL23A, TNFalpha, IL1B, and IFNG) alongside an upregulation of the immunosuppressive IL10, indicative of a dysregulated immune environment. Serum analysis showed elevated IL6 and IL10 levels in both moderate and severe cases, emphasizing their potential as markers for disease severity. Notably, no significant differences in serum cytokines were found between recovery and lethal cases. In lethal cases of COVID-19, elevated D-dimer, urea, and creatinine correlated with IL6 and IL10. This study contributes valuable information to the ongoing efforts to understand and manage the dysregulated immune responses underlying COVID-19 pathology.
期刊介绍:
Journal of Interferon & Cytokine Research (JICR) provides the latest groundbreaking research on all aspects of IFNs and cytokines. The Journal delivers current findings on emerging topics in this niche community, including the role of IFNs in the therapy of diseases such as multiple sclerosis, the understanding of the third class of IFNs, and the identification and function of IFN-inducible genes.
