Restraint stress in biomedical research: an update

Area of Science:

• Neuroscience
• Pharmacology
• Gastroenterology

Background:

• Restraint stress has been widely used since 1986 to induce stress responses in animals.
• Its primary application is investigating drug effects on stress-related pathologies, including gastrointestinal, neuroendocrine, and immunological systems.

Purpose of the Study:

• To provide an updated review of restraint stress research.
• To highlight the increasing focus on central nervous system (CNS) mechanisms in peripheral diseases, particularly gastrointestinal disorders.
• To consolidate findings on CNS-active agents and their impact on the brain-gut axis.

Main Methods:

• Review of studies employing restraint stress as a research tool.
• Analysis of investigations into drug effects on stress-induced pathology.
• Examination of central nervous system mechanisms influencing peripheral disease models.

Main Results:

• Significant research continues to utilize restraint stress for pharmacological and physiological studies.
• An increasing emphasis is observed on CNS mechanisms, especially concerning gastrointestinal disease.
• CNS-active agents demonstrate effects on gastric lesion formation and secretion, supporting the brain-gut axis concept.

Conclusions:

• Restraint stress remains a valuable model for studying stress-related pathology and drug effects.
• The brain-gut axis is increasingly recognized, with CNS-active agents showing promise in treating gastrointestinal issues.
• This update provides a comprehensive overview and bibliography of restraint stress research.
