1COVID-19-activated SREBP2 disturbs cholesterol biosynthesis and leads to cytokine storm显示文摘Sterol regulatory element binding protein-2(SREBP-2)is activated by cytokines or pathogen,such as virus or bacteria,but its association with diminished cholesterol levels in COVID-19 patients is unknown.Here,we evaluated SREBP-2 activation in peripheral blood mononuclear cells of COVID-19 patients and verified the function of SREBP-2 in COVID-19.Intriguingly,we report the first observation of SREBP-2 C-terminal fragment in COVID-19 patients’blood and propose SREBP-2 C-terminal fragment as an indicator for determining severity.We confirmed that SREBP-2-induced cholesterol biosynthesis was suppressed by Sestrin-1 and PCSK9 expression,while the SREBP-2-induced inflammatory responses was upregulated in COVID-19 ICU patients.Using an infectious disease mouse model,inhibitors of SREBP-2 and NF-κB suppressed cytokine storms caused by viral infection and prevented pulmonary damages.These results collectively suggest that SREBP-2 can serve as an indicator for severity diagnosis and therapeutic target for preventing cytokine storm and lung damage in severe COVID-19 patients.Wonhwa Lee June Hong Ahn Hee Ho Park Hong Nam Kim Hyelim Kim Youngbum Yoo Hyosoo Shin Kyung Soo Hong Jong Geol Jang Chun Gwon Park Eun Young Choi Jong-Sup Bae Young-Kyo Seo 2020Signal Transduction and Targeted Therapy2020,5,1:0
