Background: The pathogenesis of Severe SARS-CoV-2 is closely linked to severe immune responses and inflammation caused by the SARS-CoV-2 virus. In this context, the suppressor of cytokine signaling 1 (SOCS1) has a crucial role in inhibiting cytokine-induced immune responses. On the other hand, interleukin-29 (IL-29) and lysosomal trafficking regulator (LYST) are important molecules involved in inducing immune responses. Objectives: This study aimed to assess the mRNA levels of SOCS1, IL-29, and LYST in the SARS-CoV-2-infected patients with severe symptoms. Methods: In this cross-sectional study, 70 SARS-CoV-2 infected patients with severe symptoms and 70 healthy controls were evaluated. RNA was extracted from peripheral blood and after cDNA synthesis, the mRNA levels of SOCS1, IL-29, and LYST were assessed by Real-Time PCR technique Results: The study revealed that severe COVID-19 patients exhibited a significant increase in mRNA levels of IL-29 compared to healthy individuals. However, there were no observed alterations in the mRNA levels of SOCS1 and LYST in the patient group. Conclusions: The results emphasize the importance of IL-29 as a potential biomarker or therapeutic target for severe COVID-19 cases. Further research is needed to investigate the specific mechanisms through which IL-29 influences immune responses and contributes to the development of severe disease. Additionally, exploring other factors that may regulate SOCS1 and LYST expression could provide a more comprehensive understanding of their roles in COVID-19 pathogenesis.
