Plasma lipid transfer proteins include plasma cholesteryl ester transfer protein (CETP) and phospholipid transfer protein (PLTP). Plasma CETP facilitates the transfer of cholesteryl ester (CE) from high-density lipoprotein (HDL) to apolipoprotein (apo) B-containing lipoproteins, and is a key protein in reverse cholesterol transport which protects vessel walls from atherosclerosis. The importanc...
The transfer of material from phospholipid-coated microbubbles to cell membranes has been hypothesized to play a role in ultrasound-mediated drug delivery. In this study, we employed quantitative fluorescence microscopy techniques to investigate this phenomenon in both artificial and biological membrane bilayers in an acoustofluidic system. The results of the present study provide strong eviden...
The lipid substrate specificity of Manduca sexta lipid transfer particle (LTP) was examined in in vitro lipid transfer assays employing high density lipophorin and human low density lipoprotein (LDL) as donor/acceptor substrates. Unesterified cholesterol was found to exchange spontaneously between these substrate lipoproteins, and the extent of transfer/exchange was not affected by LTP. By cont...
Glycolipids are synthesized in and on various organelles throughout the cell. Their trafficking inside the cell is complex and involves both vesicular and protein-mediated machineries. Most important for the bulk lipid transport is the vesicular system, however, lipids moved by transfer proteins are also becoming more characterized. Here we review the latest advances in the glycolipid transfer ...
OBJECTIVE SAR1b plays a significant role in the assembly, organization, and function of the coat protein complex II, a critical complex for the transport of proteins from the endoplasmic reticulum to the Golgi. Recently, mutations in SARA2 have been associated with lipid absorption disorders. However, functional studies on Sar1b-mediated lipid synthesis pathways and lipoprotein packaging have n...
Background & aims: Metabolic Syndrome (MetS) is a potential threatening factor for cardiovascular disorders and atherosclerosis which is accompanied by increase in plasma triglyceride, cholesterol, low density lipoproteins (LDL-c), fasting blood sugar (FBS) and low high density lipoproteins (HDL-c). Cholesteryl ester transfer protein (CETP) catalysis transfer of lipids and phospholipids betw...
Rheumatoid arthritis (RA) is a chronic inflammatory rheumatic disease with modification of lipids profile and an increased risk of cardiovascular events related to inflammation. Plasma phospholipid transfer protein (PLTP) exerts a lipid transfer activity through its active form. PLTP can also bind to receptors such as ATP-binding cassette transporter A1 (ABCA1). In addition to its role in lipop...
We have recently purified a protein (cryoprotectin) from the leaves of cold-acclimated cabbage (Brassica oleracea) to electrophoretic homogeneity, which protects thylakoids isolated from the leaves of nonacclimated spinach (Spinacia oleracea) from freeze-thaw damage. Sequencing of cryoprotectin showed the presence of at least three isoforms of WAX9 proteins, which belong to the class of nonspec...
The microsomal triglyceride transfer protein (MTP) catalyzes the transfer of triglyceride, cholesteryl ester, and phosphatidylcholine between phospholipid surfaces. The 97-kD subunit imparts lipid transfer activity and thus plays a role in the assembly of apolipoprotein B (apoB)-containing lipoproteins. We tested whether polymorphisms in the promoter region of the large subunit of the MTP gene ...
BACKGROUND Only 2 allergenic proteins have been described in lettuce allergy: a 16-kDa protein (putative profilin) and a lipid transfer protein (LTP) named Lac s 1. OBJECTIVE Our aim was to identify the allergens involved in the anaphylactic reactions of 2 patients who had eaten lettuce. METHODS The study was performed by Ig (immunoglobulin)-E immunodetection and immunodetection-inhibition ...
