摘要：

慢性胰腺炎是一種常見的疾病，其中胰腺星狀細(xì)胞起著重要的作用。這些細(xì)胞可以活化并產(chǎn)生炎癥介質(zhì)，進(jìn)而促進(jìn)慢性胰腺炎的進(jìn)展。此外，瓦博格效應(yīng)也是胰腺炎發(fā)生和惡變的關(guān)鍵因素。本文研究顯示，活化的胰腺星狀細(xì)胞可以增強(qiáng)瓦博格效應(yīng)，從而進(jìn)一步引起慢性胰腺炎的惡變。具體而言，活化的星狀細(xì)胞可以促進(jìn)纖維化和局部免疫失調(diào)，導(dǎo)致腫瘤的發(fā)生和轉(zhuǎn)移。此外，本文還討論了一些可能的治療方案，包括瓦博格效應(yīng)抑制劑和脅迫素治療。
