Cystinosis metabolic bone disease: inflammatory profile in human peripheral blood mononuclear cells and derived osteoclasts.

ABSTRACT: Cystinosis metabolic bone disease (CMBD) is an emerging concept in infantile nephropathic cystinosis, patients presenting with bone pains, fractures, and deformations during teenage or early adulthood. The underlying mechanisms remain unclear. Our aim was to explore the pro-inflammatory profile of osteoclastic lineage in cystinotic patients. We obtained blood samples from 14 cystinotic patients and 10 pediatric healthy controls. Peripheral blood mononuclear cells (PBMCs) were isolated and used to explore by RT-qPCR the transcript expression of 8 inflammatory markers (Il-6, Il-8, Il-1β, CXCL1, CCL2/MCP-1, CXCR3, Il-1 Receptor, Il-6 Receptor). In addition, when possible, PBMCs were differentiated into osteoclasts for further experiments. The expression of Il-6, IL-8, CXCR3, and CCL2/MCP-1 wa
