Transport of cholesterol in the hemolymph of the mollusc Diplodon delodontus

Blood lipids of the small octopus, Octopus tehuelchus (mollusca, cephalopoda) at different stages of sexual maturation

“…This leads us to suggest that cholesterol is partly carried by hemocytes. This hypothesis is supported by a recent demonstration of cholesterol transport by hematic cells in bivalve molluscs (Pollero, 1987). The qualitative composition of plasmatic fatty acids is the same as the one we initially found in tissue analyses of O. tehuelchus (results not published).…”

“…It can, therefore, be speculated that this finding indicates some role played by hemocytes in the lipid transport. Uptake and transport of certain lipid classes by hematic cells, has also been previously reported in other aquatic molluscs following in vivo and in vitro labelling experiments (Pollero et al, 1985;Pollero, 1987). However, the relative proportion of lipids in O. tehuelchus plasma and hemocytes, strongly indicates that most of the lipids are carried in association with plasma.…”

Lipid circulation in spiders. Transport of phospholipids, free acids and triacylglycerols as the major lipid classes by a high-density lipoprotein fraction isolated from plasma of Polybetes pythagoricus

“…The mechanisms of lipid circulation are wellknown in many arthropods; they are transported by means of high-(HDL) or very high-density lipoproteins (VHDL) in insects (Beenakkers et al, 1985) or only by HDLs in crustaceans (Lee, 1989). Plasma lipid circulation in molluscs is comparatively less known, although it has been studied in our laboratory, firstly in bivalves (Pollero, 1987), then in cephalopods (Heras and Pollero, 1990), and recently in gastropods (Pollero et al, 1992).…”
