•Cistanche deserticola polysaccharide ameliorated the inflammation of postmenopausal osteoporosis development.•Cistanche deserticola polysaccharide regulates the proportion of Th17/Treg.•Cistanche deserticola polysaccharide restored the profiles of gut flora and short-chain fatty acids.•SCFAs modified by Cistanche deserticola polysaccharide were negatively related to postmenopausal osteoporosis.
Chronic inflammation plays a critical role in the pathogenesis of postmenopausal osteoporosis (PMO). Short-chain fatty acids (SCFAs) produced by the gut microbiota (GM) have emerged as key regulators of the inflammatory response. Cistanche deserticola polysaccharide (CDP), derived from the traditional Chinese medicine Cistanche deserticola, possesses potent anti-inflammatory properties. However, the precise mechanism by which CDP modulates inflammation in PMO via the gut-bone axis remains elusive. In this study, we elucidated that CDP could effectively restore GM composition, ameliorate intestinal mucosal damage, elevate SCFA levels, rebalance the Th17/Treg cells equilibrium, attenuate the accumulation of proinflammatory cytokines, potentially facilitate osteoblast differentiation, potentially suppress osteoclastogenesis, and enhance bone microarchitecture in PMO mice. Collectively, our findings provided compelling evidence that CDP alleviated PMO-associated inflammation, potentially mediated through the intricate interplay between GM-derived SCFAs and the Th17/Treg cells. |
