What is it about?
Osteoporosis is a condition where bones become weak and brittle, and not all patients respond well to the usual treatments, like bisphosphonates. But why some patients don't improve with these treatments has been unclear. Our research, for the first time, reveals the diversity observed in immune cells of osteoporosis patients and those who fail to respond to treatment.

Why is it important?
Through years of follow-up investigation, we recruited patients and collected blood samples to perform single-cell RNA sequencing. Surprisingly, we observed an increase in the proportion of natural killer cells in patients who failed bisphosphonate treatment. We also identified specific gene expressions and cell signaling networks unique to treatment failure patients. Furthermore, we observed differences in gene expression and cell signaling between healthy individuals and osteoporotic patients. These findings can be utilized as biomarkers to improve osteoporosis diagnosis and may serve as targets for new drugs and adjunct therapies in various research applications.
