Experimental models of lung transplantation

Area of Science:

• Transplantation immunology
• Surgical innovation
• Pulmonary medicine

Background:

• Lung transplantation is a life-saving treatment for end-stage pulmonary diseases.
• The clinical success of lung transplantation relies heavily on advancements made through animal research.
• Various animal models have played pivotal roles in overcoming surgical and immunological challenges.

Purpose of the Study:

• To review the critical contributions of diverse animal models to the development of lung transplantation.
• To highlight how different species have facilitated key breakthroughs in surgical techniques and immunosuppression.
• To emphasize the ongoing importance of animal models in understanding and overcoming lung graft failure.

Main Methods:

• Review of historical and contemporary animal models used in lung transplantation research.
• Analysis of canine models for initial surgical and immunosuppressive advancements.
• Examination of rat and mouse models for detailed immunological and genetic studies.

Main Results:

• Canine models were instrumental in early surgical techniques and immunosuppression, enabling the first human lung transplants.
• Rat models facilitated in-depth investigations of immune responses to lung allografts.
• Mouse models, particularly for tracheal and orthotopic vascularized lung transplants, have enabled genetic and molecular studies of graft failure.

Conclusions:

• Animal models have been indispensable throughout the history of lung transplantation development.
• Each model, from dogs to rodents, has provided unique insights and capabilities for research.
• Continued use of animal models is vital for future progress in lung transplantation and improving patient outcomes.
