The spots for macrophage chemoattractant protein (MCP)–1, interferon-, TGF-2, interleukin-8, and IGFBP-1 showed a marked density increase as compared with the CSF control. (B–I) Profile of expression (fold increase) of cytokines that were found markedly increased in autistic patients as compared with controls. p
