Experimental Models of Acute Lung Injury to Study Inflammation and Pathophysiology: A Narrative Review

Area of Science:

• Pulmonary Medicine
• Inflammation Research
• Preclinical Drug Development

Background:

• Acute lung injury (ALI) is a critical respiratory condition with high mortality, characterized by respiratory insufficiency and alveolar damage.
• Histopathological features of ALI include neutrophilic alveolitis and microvascular thrombi, often leading to multiple organ dysfunction.
• Existing animal models like LPS-induced ALI, hyperoxia-induced ALI, and ventilator-induced lung injury (VILI) are crucial for studying ALI mechanisms.

Purpose of the Study:

• To present selected preclinical mouse models for acute lung injury (ALI).
• To demonstrate the utility of these models as a proof of concept for evaluating novel anti-inflammatory drugs.
• To discuss the specific characteristics and appropriate applications of each model.

Main Methods:

• Review of established preclinical mouse models for inducing acute lung injury.
• Focus on models suitable for in vivo drug testing.
• Discussion of model particularities and their relevance for anti-inflammatory drug screening.

Main Results:

• Selected mouse models serve as effective proof-of-concept systems for anti-inflammatory drug efficacy in ALI.
• The choice of model is critical and depends on the specific research question and drug properties.
• These models facilitate the investigation of therapeutic interventions for ALI.

Conclusions:

• Preclinical mouse models are essential for advancing the understanding and treatment of acute lung injury.
• These models provide a framework for testing novel anti-inflammatory agents in a controlled in vivo setting.
• Further research utilizing these models can lead to the development of effective therapies for ALI.
