Further Studies of Lipid Droplets in the Bombykol‐Producing Pheromone Gland of Bombyx mori

Lipid droplets are abundant in the pheromone-producing cells of B. mori at adult eclosion, followed by daily fluctuations in both their size and number. Their dynamics are related to PBAN-stimulated de novo bombykol production. To elucidate associated events, we performed the following: (1) extraction, purification, and partial characterization of lipid droplet-associated proteins found on their surface since their function could possibly be to transport and/or dock putative lipases that are responsible for the lipolysis of triglycerides in them; (2) separation, purification, and initial analysis of lipids carried by lipophorins and lipid transfer particles originating from pupal and adult hemolymph because of their role in the formation and accumulation of lipid droplets.
