Leucokinin VIII is an diuretic octapeptide isolated form head extracts of the cockroach.
Leucokinin VIII is an octapeptide, increases the rates of transepithelial NaC1, KC1 and water secretion, increases the Cl conductance of the epithelial shunt via a receptor located at the basolateral side of the epithelium[1]. Leucokinin VIII also activates Ca2+-dependent signal pathway in principal cells of Aedes aegyptiMalpighian tubules[2].

Localization of Leucokinin VIII in the cockroach, Leucophaea maderae, using an antiserum directed against an achetakinin-I analog
Neurochem Res 1994 Jul;19(7):805-14.PMID:7969749DOI:10.1007/BF00967448.
An antiserum against an achetakinin analog selectively localized Leucokinin VIII (LKVIII) in the CNS of Leucophaea maderae. Preabsorption studies of the achetakinin antiserum with either preimmune serum or LKVIII prevented a positive reaction in both ELISA and immunocytochemical procedures. LKVIII immunoreactive neurons were found in the brain, frontal, and subesophageal ganglion, all 3 thoracic ganglia and the terminal ganglion. Nerves originating from the thoracic and terminal abdominal ganglia contain LKVIII material. Lateral and medial neurosecretory cells synthesizing LKVIII-like products contribute axons to the nervi corporis cardiaci that terminate in neurohemal sites in the corpora cardiaca and nervi corporis allati. Thus, Leucokinin VIII, like leucokinin I (LKI) and leucomyosuppressin (LMS), appears to have both a neurohemal and neurotransmitter mode of regulating target cells in L. maderae.
