Immunocytochemical localization of leptin hormone in the neurosecretory cells of brain–suboesophageal ganglion complex of tropical tasar silkworm, Antheraea mylitta (D.) eco-race Bhandara
Leptin is a peripheral agent known for its function in feeding behaviour in vertebrates. In this study, we demonstrated leptin immunoreactivity in the brain and suboesophageal ganglion (SOG) of tropical tasar silkworm, Antheraea mylitta (D.) by immunohistochemistry using polyclonal antibody against mammalian leptin. Leptin immunoreactivity was not observed in the adult brain, whereas, intense reactivity was detected in the single neuronal group of cells in SOG. This study provides an essential groundwork to further elucidate the involvement of leptin in insect development and appetite regulatory systems of tropical tasar silkworm, Antheraea mylitta (D.) as well as in other insects.
Keywords
