TGFB1 and autism: Other studied areas with probably less incidence in autism are the fine motor skills (down-regulated IL-5, up-regulated MCP-1, RANTES, and eotaxin), visual reception (up-regulated IL-8, MCP-1, RANTES, and eotaxin) [138,205,216], and adaptive and cognitive functions (highMCP-1, RANTES, and eotaxin, low TGF-β1, and GM-CSF) [66,134].
