What this means
This review pulls together earlier studies on gut bacteria, nerves, and bone marrow immune cells. It suggests these may link to bone loss, but it does not prove cause and effect.

Abstract
Age-related osteoporosis arises from the interplay between impaired bone remodeling, immune remodeling, and chronic low-grade inflammation during aging. Beyond local degeneration in bone tissue, alterations in the gut microbiota, mucosal barrier, and autonomic nervous regulation may reshape the bone marrow immune environment and amplify osteoclastogenic responses. This review integrates evidence linking the gut, neural regulation, and the bone marrow immune microenvironment. It summarizes their potential contributions to age-related bone loss and provides a conceptual framework for understanding disease mechanisms, improving risk stratification, and optimizing intervention strategies.
