Stronger bones thanks to heat and microbiota

Stronger bones thanks to heat and microbiota - تاثیر آب و هوا بر پوکی استخوان
Osteoporosis, a bone disease linked to ageing, is characterised by a loss of bone density, micro-architectural deterioration of the bones and an increased risk of fractures. With one third of postmenopausal women affected, it is a major public health problem. Through epidemiological analyses, laboratory experiments and state-of-the-art metagenomic and metabolomics tools, a research team has observed that exposure to warmer ambient temperatures (34 °C) increases bone strength, while preventing the loss of bone density typical of osteoporosis. Moreover, this phenomenon, linked to a change in the composition of gut microbiota triggered by heat, could be replicated by transplanting the microbiota of mice living in a warm environment to mice suffering from osteoporosis. Indeed, after the transplant, their bones were stronger and denser. These results, to be discovered in Cell Metabolism, make it possible to imagine effective and innovative interventions for prevention and treatment of osteoporosis.
