Abstract
根據GINA 2024指南,嚴重氣喘是使用高劑量ICS-LABA治療後仍無法控制病情的氣喘。因此,需要新的治療方法。先前研究顯示,凝血酶誘導的IL-8/CXCL8表現與嚴重氣喘的肺上皮細胞有關。Serine/threonine kinase 33 (STK33) 隸屬於Calcium/calmodulin-dependent kinase (CAMK) 家族,在特發性肺纖維化病人的表現增加,推測其在呼吸道相關疾病扮演角色。此外,STK33可被ERK磷酸化,且能增加c-Myc的轉錄活性。本論文旨在探討Serine/Threonine Kinase 33 (STK33)在嚴重氣喘中Thrombin誘導趨化因子IL-8/CXCL8表現之角色。成果發現,STK33高度表現嚴重氣喘患者和Ovalbumin (OVA) 誘導氣喘的小鼠模型的呼吸道組織,並且在後者看到c-Myc的磷酸化增加情形。另外,STK33/c-Myc參與凝血酶刺激A549和BEAS-2B上皮細胞導致IL-8/CXCL8釋放,且STK33在A549細胞中與ERK產生交互作用、調控c-Myc磷酸化表現,並使c-Myc與細胞核中的IL-8/CXCL8啟動子結合,增強肺上皮細胞釋放IL-8/CXCL8。綜合以上結果,突顯了STK33是一個有潛力治療嚴重氣喘的治療標的。
