WebA reduction in Tc REG numbers may lead to an increase in bone resorption, and the subsequent increase in HPC mobilization. More studies are needed to explore the consequences of this bidirectional regulation for both the bone and autoimmune regulations and to identify the sensors that mediate this regulation. WebBone resorption is the process of breaking down the bones into its mineral and collagenous constituents through a cellular mechanism. The process may be part of the normal regulation of minerals such as calcium in the blood or it could also be due to a pathological or disease process, which accelerates the rate of bony breakdown.
