A??-stimulated human monocytes generate chemokines such as IL-8, monocyte chemoattractant protein- (MCP)-1, macrophage inflammatory protein- (MIP)-1?? and MIP-1?? in vitro, and microglia cultured from rapid autopsies of AD and nondemented patients reveal an increased expression of IL-8, MCP-1, and MIP-1?? after experimental exposure to A??.
