CXCL8 and frontotemporal dementia: The analysis showed that the greatest component of variance in FTD brain consisted of β -NGF, eotaxin, G-CSF, granulocyte–macrophage colony stimulating factor (GM-CSF), IFN-α2, IFN-γ, IL-10, IL-12 (p40), IL-12 (p70), IL-13, IL-15, IL-16, IL-17A, IL-1α, IL-2Rα, IL-3, IL-4, IL-6, IL-7, IL-8, IL-9, LIF, MCP-3, monocyte induced by gamma interferon (MIG/ CXCL9), MIP-1α, MIP-1β, PDGF-BB, stem cell factor (SCF), stromal cell derived factor-1 alpha (SDF1α), TNF-α, TNF-β and VEGF (loading score > 0.7, accounting for 51% of variance) (Table 4).
