Pathways of SCFA affecting bone homeostasis. 1) SCFA reduces intestinal pH and increases calcium absorption. 2) SCFA inhibits the differentiation of osteoclasts by increasing the occurrence of intracellular glycolysis. 3) SCFA inhibits the activity of HDAC, thus increasing the differentiation of Treg cells. 4) SCFA can induce the increase of IGF-I.
