We have recently found delayed maturation of NeuN and other neuronal protein markers in ganglion cells, as well as sparse synaptophysin reactivity in the myenteric plexi in a series of small bowel segmental resections and at autopsy in preterm infants with intestinal dysmotility syndrome, which explains poor peristalsis [Yu W, Pinto-Rojas A, Sarnat HB, in preparation]. Here, SYP is linked to intestinal dysmotility syndrome.
