Crawling Paths of Larvae (IMAGE) University at Buffalo Caption Colored lines show the paths of crawling fruit fly larvae. Larvae with a mutant form of the human huntingtin protein that causes Huntington's disease crawled poorly (center) compared with normal larvae (left). But when larvae carrying the Huntington's disease protein also produced extra quantities of the Rab4 protein, crawling improved, though not completely (right).
