Mechanism of Action
Protecting intestinal barrier: Bifidobacteria can increase the expression of mucin and tight junction proteins, thus protecting the intestinal barrier function, reducing intestinal permeability, preventing pathogens and harmful substances from entering the body, and thus reducing inflammatory reactions.
Regulate intestinal flora: Bifidobacteria can increase the abundance of beneficial bacteria and decrease the abundance of harmful bacteria, thus maintaining the balance of intestinal flora and reducing inflammatory reactions.
Inhibit inflammatory response: Bifidobacteria can inhibit the expression of inflammatory factors in the intestine, thus inhibiting the production of osteoclasts and reducing bone loss.
Research Implications
Reveals the relationship between intestinal immunity and bone health: This study reveals the relationship between intestinal immunity and bone health, providing new ideas for osteoporosis prevention and treatment.
Provides a theoretical basis for the treatment of osteoporosis by probiotics: This study provides a theoretical basis for the treatment of osteoporosis by probiotics, and provides a new direction for the development of new therapeutic drugs for osteoporosis.
Future Research Directions

Study Details
Animal model: The researchers used a de-ovulated mouse model to simulate the physiological state of postmenopausal women.
Intervention: The researchers administered Bifidobacterium bifidum strains by gavage to ovariectomised mice, and set up ovariectomised and sham-operated groups as controls.
Measurements: The researcher measured the bone density, bone volume, number of bone trabeculae, number of osteoclasts, bone turnover, intestinal inflammation, and intestinal flora structure of the mice.
Data analysis: The researchers used statistical methods to analyse the experimental data and explored the mechanism of action of bifidobacteria.
Summary
The results of this study suggest that Bifidobacterium bifidum can ameliorate estrogen deficiency-induced osteoporosis by regulating intestinal immunity and intestinal flora. This study provides new ideas for the prevention and treatment of osteoporosis and provides a new direction for the development of new therapeutic drugs for osteoporosis.
