Localization of SNARE proteins in the brain and corpus allatum of Bombyx mori

open access: yesHistochemistry and Cell Biology, 2022
Abstract Soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs) comprise the core machinery that mediates membrane fusion. SNAREs, syntaxin, synaptosome-associated protein (SNAP), and synaptobrevin form a tight SNARE complex that brings the vesicle and plasma membranes together and is essential for membrane fusion.

Fura-2 measurement of cytosolic free Ca2+ concentration in corpus allatum cells of larval Manduca sexta [PDF]

open access: yes, 1992
Cytosolic free Ca2+ has been implicated in the regulation of the larval corpus allatum (CA) of the tobacco hornworm Manduca sexta since agents presumed to cause changes in intracellular Ca2+ concentrations affect both basal and neuropeptide-modulated ...

Structure Determination of a Natural Juvenile Hormone Isolated from a Heteropteran Insect

open access: yesPsyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
Juvenile hormone (JH), which occurs in several forms in different insects, is one of the most important insect hormones. The structure of JH in Heteroptera has not been elucidated until recently, although insects in this suborder have long been used as experimental animals for JH research.
