MIF and vasculitis: Monocyte chemoattractant proteins (MCP), monocyte inhibitory factor (MIF), C-X-C motif ligand 13 (CXCL13), and C-C motif ligand 23 (CCL23), have been implicated in intraparenchymal leukocyte migration, vasculitis and, in the case of CCL23, MIF, and MCP-1, are linked to the progression of dementia by supporting chronic neuroinflammation [68,69,70,71,72,73,74].
