In more detail, we reported that SCI-ECP and SCI-LCP patients seemed to present increased proportions of CD4+ CD25+/low Foxp3+ Tregs in comparison to HC, whereas a decreased number of these cells expressing CCR5 was observed in SCI-SP, SCI-ECP, and SCI-LCP patients. The gene discussed is FOXP3; the disease is Legg-Calve-Perthes disease.
