Nutraceuticals in joint health: animal models as instrumental tools

Area of Science:

• Biomedical Science
• Pharmacology
• Nutraceutical Research

Background:

• Osteoarthritis (OA) is a prevalent degenerative joint disease lacking definitive cures.
• Nutraceuticals are increasingly investigated for their potential to mitigate OA progression.
• Evaluating nutraceutical efficacy requires robust preclinical models.

Purpose of the Study:

• To review animal models used in studying nutraceutical effects on osteoarthritis.
• To provide guidance on selecting appropriate OA models for nutraceutical research.
• To highlight the diversity of available animal models for OA research.

Main Methods:

• Systematic review of existing literature on animal models for OA and nutraceutical intervention.
• Analysis of different types of OA induction methods in animal studies.
• Categorization of animal models based on relevance to OA pathophysiology.

Main Results:

• A wide array of animal models are currently employed to study OA.
• Each model possesses unique advantages and limitations for evaluating nutraceuticals.
• Model selection significantly impacts the interpretation of nutraceutical efficacy.

Conclusions:

• Standardized guidelines for selecting animal models in nutraceutical OA research are needed.
• Appropriate model selection is crucial for validating the therapeutic potential of nutraceuticals.
• Further research should focus on aligning specific OA models with desired nutraceutical outcomes.
