CCL5 and frontotemporal dementia: In a recent study on FTD patients, out of the measured factors (monocyte chemoattractant protein-1 (MCP-1), regulated upon activation, normal T-cell expressed and secreted protein (RANTES), IL-10, IL-17A, IL-12p, IFN-γ, IL-8, IL-1β, leukocytes, and C-reactive protein (CRP)), only serum IL-10 was different between C9orf72 FTD and non-C9orf72 FTD patients (carriers had higher levels), which negatively correlated to a more rapid disease progression [185].
