Pharmacological postconditioning: a molecular aspect in ischemic injury

Area of Science:

• Cardiovascular Research
• Cellular Biology
• Medical Science

Background:

• Ischaemia/reperfusion (I/R) injury results from blood flow restoration after a period of oxygen deprivation.
• Current protective agents for I/R injury face limitations such as monotargeting, low potency, delayed delivery, and poor tolerability, hindering clinical application.

Purpose of the Study:

• To review the mechanisms of pharmacological postconditioning (pPoCo) in mitigating I/R injury.
• To explore the role of various receptors and signaling pathways in pPoCo's protective effects.
• To identify the need for optimized clinical protocols for pPoCo translation.

Main Methods:

• Systematic review of preclinical studies on pharmacological postconditioning (pPoCo).
• Analysis of various animal models investigating pPoCo mechanisms.
• Examination of different receptors and signaling pathways involved in pPoCo.

Main Results:

• Postconditioning (PoCo), particularly pharmacological pPoCo, presents a viable strategy to address I/R injury.
• pPoCo can be induced rapidly or in a delayed manner, offering clinical flexibility, especially for unannounced ischaemic events.
• Preclinical studies demonstrate the efficacy of various pPoCo mechanisms across different animal models.

Conclusions:

• pPoCo holds significant therapeutic potential for managing I/R injury.
• Optimization of clinical protocols is crucial for accelerating the translation of pPoCo into clinical practice.
• Further research is needed to fully elucidate the complex receptor and signaling pathways underlying pPoCo's protective effects.
