- CTD-ILDの既存の管理ガイドラインと治療法は,サブタイプ特有の疾患メカニズムの理解が不十分であり,異なるCTD-ILD病理に合わせた治療法を使用していないため,しばしば無効です.
- パーソナライズされた治療戦略を容易にするために,異なるCTD-ILDサブタイプの異質性と特定の病原性メカニズムを正確に反映する改善された臨床前モデルの必要性があります.
研究 の 目的:
- CTD-ILDの研究に使用されている現在の動物モデルをレビューし,批判的に評価する.

- 既存のモデルとヒトCTD-ILDの格差を特定する.
- CRISPR/Cas9などの新興技術の探索,人間化されたマウス,およびオルガノイドシステム.
主要な成果:
- 現在のCTD-ILD動物モデルでは,ヒト患者で観察された多様なサブタイプと特定の病原性メカニズムを完全に複製することができません.
- 確立された動物モデルとそれに対応するヒトCTD-ILDの間で大きな差異があり,その翻訳的価値を制限しています.
- 新興技術はより正確で予測可能な 臨床前モデルの構築に 有望な可能性を秘めています

01:20COPD: Pathogenesis and Clinical Features
2.1K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

906
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

01:20Chronic Obstructive Pulmonary Disease-I: Introduction
4.0K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:

4.7K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

01:23Chronic Obstructive Pulmonary Disease I: Introduction

Chronic obstructive pulmonary disease is a common, preventable, and treatable respiratory disorder characterized by persistent symptoms and progressive airflow limitation. This limitation results from a combination of small-airway disease (obstructive bronchiolitis) and parenchymal destruction (emphysema), both driven by chronic inflammation from exposure to harmful particles or gases.The disease includes two main pathological entities: emphysema, marked by destruction of alveolar walls and...
