研究目的: |
1. 揭示PICS在脓毒症患者中的发生率,明确其对患者预后的影响。构建脓毒症PICS预测模型,辅助脓毒症晚期患者的临床决策。 2. 解析脾脏免疫细胞亚群在脓毒症晚期免疫抑制中的变化规律及作用,阐明脾脏EV在体内外的分布和生物学功能。 3. 挖掘PICS-sEV高度亲和于肺的分子机制,明确PICS-sEV发挥免疫抑制功能的生物学组分,找寻脓毒症免疫抑制潜在的治疗靶点。 4. 验证脓毒症患者临床样本中sEV及其效应成分的表达水平,评估其作为预测脓毒症免疫抑制严重程度及患者预后生物标记物的可行性。 总而言之,本项目旨在揭示“脓毒症晚期肿大的脾脏如何通过释放sEV,递送促免疫抑制相关组分,实现‘脾—肺’轴互作,影响肺内固有免疫的作用及机制”,为靶向调控这些EV或其效应成分,治疗脓毒症免疫抑制,提供新策略、新方法;为后续阐明脓毒症免疫抑制的发病机制提供新思路、新方向。 |

Objectives of Study: |
1. To reveal the incidence of PICS in patients with sepsis and clarify its impact on patient prognosis. To construct a sepsis PICS prediction model to assist clinical decision-making for patients in the late stage of sepsis. 2. Analyze the changes and roles of spleen immune cell subsets in immunosuppression during the late stage of sepsis, and elucidate the distribution and biological functions of spleen EV both in vivo and in vitro. 3. Explore the molecular mechanism behind the high affinity of PICS-sEV for the lungs, identify the biological components responsible for the immunosuppressive function of PICS-sEV, and seek potential therapeutic targets for sepsis-induced immunosuppression. 4. Verify the expression levels of sEV and its effector components in clinical samples from sepsis patients, and assess the feasibility of using them as biomarkers for predicting the severity of immunosuppression and patient prognosis in sepsis. In summary, this project aims to reveal "how the enlarged spleen in late sepsis releases sEVs to deliver immunosuppression-promoting components, achieving 'spleen-lung' axis interaction and influencing the role and mechanism of intrinsic immunity in the lungs". It provides new strategies and methods for targeting and regulating these EVs or their effector components to treat sepsis-induced immunosuppression, and offers new ideas and directions for further elucidating the pathogenesis of sepsis-induced immunosuppression. |
