  • Title: Sex-related differences in the concentration of Met-enkephalin-like immunoreactivity in the nervous system of an insect, Schistocerca gregaria, revealed by radioimmunoassay.
    Author: Davenport AP, Evans PD.
    Journal: Brain Res; 1986 Sep 24; 383(1-2):319-22. PubMed ID: 3768696.
    Abstract:
    A radioimmunoassay has been used to measure Met-enkephalin-like immunoreactivity in tissue from male and female locusts, Schistocerca gregaria. The pattern of distribution within the two sexes was similar with about equal amounts present in the suboesophageal and 3 thoracic ganglia and a lower concentration in the cerebral ganglion. Female nervous tissue contained more than twice the amount of Met-enkephalin-like immunoreactivity than did that of males. No consistent immunoreactivity could be detected in the abdominal ganglia or non-neural tissues. The results are discussed in relation to recent evidence that peptides related or identical to enkephalins are present in invertebrates as well as higher organisms.
