Antisera were raised against leucokinin IV, a member of the leucokinin peptide
family. Immunohistochemical localization of leucokinin immunoreactivity in the
brain of the cockroach Nauphoeta cinerea revealed neurosecretory cells in the
pars intercerebralis and pars lateralis, several bilateral pairs of interneurons
in the protocerebrum, and a group of interneurons in the optic lobe. Several
immunoreactive interneurons were found in the thoracic ganglia, while the
abdominal ganglia contained prominent immunoreactive neurosecretory cells, which
projected to the lateral cardiac nerve. The presence of leucokinins in the
abdominal nerve cord was confirmed by HPLC combined with ELISA.
Leucokinin-immunoreactive neurosecretory cells were also found in the pars
intercerebralis of the cricket Acheta domesticus and the mosquito Aedes aegypti,
but not in the locust Schistocerca americana or the honey bee Apis mellifera.
However, all these species have leucokinin-immunoreactive neurosecretory cells in
the abdominal ganglia. The neurohemal organs innervated by abdominal
leucokinin-immunoreactive cells were different in each species.
