阻断化学素受体可能有助于治疗2型糖尿病患者的结核病. 这种方法可以减少与这种复杂疾病相关的肺炎.
科学领域:
- 免疫学
- 内分泌学
- 传染性疾病
背景情况:
- 在肥胖和2型糖尿病中,素含量升高.
- 二型糖尿病增加了结核病 (TB) 的风险,严重程度和耐药性.
- 糖尿病结核病患者表现出免疫反应受损和微生物杀伤能力下降.
研究的目的:
- 调查化学素对巨细胞的炎症作用.
- 在高血糖小鼠中确定基梅林在肺部感染的作用.
主要方法:
- 用高血糖介质和M.结核病治疗的骨髓衍生巨细胞 (BMDM).
- 在化学剂治疗后分析炎症性细胞因子分泌物 (IL-6,IL-10).
- 使用肥胖 (HFD) 和糖尿病 (db/db) 感染M.结核病的小鼠.
- 给受感染的db/ db小鼠使用化学素受体抗剂 (CCX832).
主要成果:
- 在感染M. tuberculosis的高血糖BMDM患者中,用Chemerin治疗增加了IL-6和降低了IL-10.
- 肥胖患者和非糖尿病患者的BMDM具有炎症性;肥胖患者和糖尿病患者的BMDM与对照组没有差异.
- 在体内,db/db小鼠的细菌负载和肺炎较高.
- 在db/ db小鼠中,抗原治疗减少了肺炎,但没有影响细菌负载.
结论:
- 在结核病期间,化学信号会加剧2型糖尿病的肺炎.
- 阻断化学素受体 (ChemR23) 可能会减轻糖尿病患者的结核相关肺病态.
- 这表明可能是治疗复杂结核病的辅助疗法.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
Primary Symptoms of COPD:
Chronic Obstructive Pulmonary Disease-II: Pathophysiology
Chronic Inflammation

Pulmonary Tuberculosis III
The first classification is based on the development of the disease, and it includes the following categories:
Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
