Differential incorporation of precursor moieties into cerebral cortex and cerebellum glycerophospholipids during aging
(Springer/Plenum Publishers, 2000-06)
The incorporation of polar and non-polar moieties into cerebral cortex (CC) and cerebellum (CRBL) phospholipids of adult (3.5-month-old) and aged (21.5-month-old) rats was studied in a minced tissue suspension. The ...
StarD7 behaves as a fusogenic protein in model and cell membrane bilayers
(Elsevier Science, 2012-03-03)
StarD7 is a surface active protein, structurally related with the START lipid transport family. So, the present work was aimed at elucidating a potential mechanism of action for StarD7 that could be related to its interaction ...
Identification and Characterization of the Lipid Transport System in the Tarantula Grammostola rosea
(Scientific Research Publishing, 2015-01)
Lipids due to its hydrophobic nature are transported in the hemolymph mainly by lipoproteic fractions. In the present work we studied the lipoproteic fractions present in the hemolymph of the spider Grammostola rosea. ...
Influence of temperature, anions and size distribution on the zeta potential of DMPC, DPPC and DMPE lipid vesicles
(Elsevier Science, 2015-03)
The purpose of the work is to compare the influence of the multilamellarity, phase state, lipid head groups and ionic media on the origin of the surface potential of lipid membranes. With this aim, we present a new ...
High lipid content of irradiated human melanoma cells does not affect cytokine-matured dendritic cell function
(Springer, 2013-01)
Gamma irradiation is one of the methods used to sterilize melanoma cells prior to coculturing them with monocyte-derived immature dendritic cells in order to develop antitumor vaccines. However, the changes taking place ...
Characterization of Cell Wall Lipids from the Pathogenic Phase of Paracoccidioides brasiliensis Cultivated in the Presence or Absence of Human Plasma
(Public Library Science, 2013-05-17)
Background: the fungal cell wall is a complex and dynamic outer structure. in pathogenic fungi its components interact with the host, determining the infection fate. the present work aimed to characterize cell wall lipids ...
Headgroup specificity for the interaction of the antimicrobial peptide tritrpticin with phospholipid Langmuir monolayers
(Elsevier B.V., 2012-12-01)
We examined the interaction of the cationic antimicrobial peptide (AMP) tritrpticin (VRRFPWWWPFLRR, TRP3) with Langmuir monolayers of zwitterionic (dipalmitoyl phosphatidylcholine, DPPC, and dipalmitoyl phosphatidylethanolamine, ...
Impact of age on reproductive outcome in women with recurrent spontaneous abortions and infertility of immune etiology
The objective of this paper is to determine whether age has any impact on conception rate, pregnancy outcome, or autoimmune status in women with recurrent spontaneous abortions (RSA) and infertility of immune etiology. One ...
The inhibition of microtubule dynamics instability alters lipid homeostasis in TM4 Sertoli cells
(Academic Press Inc Elsevier Science, 2021-09-02)
Sertoli cells (SC) structurally support and transport nutrients to germ cells during spermatogenesis facilitated by an active cytoskeleton. Chemical perturbation of SC microtubule (MT) dynamics instability leads to premature ...
Dietary fat saturation produces lipid modifications in peritoneal macrophages of mouse
(Elsevier Science Inc, 2003-07)
We investigated the effects of a saturated fat diet on mice lipid metabolism in resident peritoneal macrophages. Male C57BL/6 mice were weaned at 21 days of age and assigned to either the experimental diet, containing ...
