Pb(II) Induces Scramblase Activation and Ceramide-Domain Generation in Red Blood Cells

Moreover, PLSCR1 appears to play important roles at the nuclear level, apparently unrelated to membrane lipid motions 57 Busto1, 2 Bingen G. We had also observed that mechanical stress elicited a neutral sphingomyelinase activity in erythrocytes In addition, partial non-cytotoxic cholesterol depletion of red blood cells accelerates the process as the morphological change occurs faster.

The involvement of a scramblase activity in PS translocation was demonstrated by transfection of a scramblase gene into Chinese hamster ovary CHO cells. Note that the amount of Cer in overnight-treated cells will be higher than that present after the treatments described in Fig.

The characteristic biconcave shape is lost in the first minutes, and the cells become almost flat Fig. Ceramide generation is linked to the morphological change and the process can be stopped at this point using GW neutral sphingomyelinase inhibitor.


Cells were then fixed and stained. The samples were diluted 1: Support Center Support Center. The Journal of experimental medicine.

Bkofisika translocation across the biofiskia membrane of mammalian cells. Iannelli A, et al. Recent findings suggest that PS exposure also occurs under non-apoptotic conditions. This is biocisika clear in Fig. This is followed by PS exposure in the outer membrane leaflet. The meaning of these hot spots of scramblase activity is not clear at present.

Whole blood was obtained from informed healthy volunteers by venipuncture. Battistini V, et al. Exposure of anionic phospholipids serves as anti-inflammatory and immunosuppressive signal—implications for antiphospholipid syndrome and systemic lupus erythematosus. This metal causes a broad range of biochemical, physiological and behavioural dysfunctions. The process was repeated two more times to increase efficiency. Functions of ceramide in coordinating cellular responses to stress.

Ceramide species were also quantified with a loss of water in the first quadrupole. Confocal images were acquired with an Olympus Fluoview FV confocal microscope.

Supplementary information accompanies this paper at bofisika The former was labeled with an antiCer specific antibody ALX— as primary, Alexa Fluor as secondarywhile the latter was identified through the ability of PS to bind Annexin V.


Asymmetric addition of ceramides but not dihydroceramides promotes transbilayer flip-flop lipid motion in membranes. Notes Competing Interests The authors declare no competing interests. British journal of industrial medicine.

However, ceramide-enriched domains have been already reported for erythrocytes under a hot-cold jhrnal process ALX— specificity against ceramide has been questioned Chemistry and bioifsika of lipids.

S-allyl cysteine in combination with clotrimazole downregulates Fas induced apoptotic events in erythrocytes of mice exposed to lead.

Montes LR, et al. All other reagents and solvents for assay were of analytical reagent grade and were purchased from Sigma-Aldrich.

Clotrimazole blocks potassium channels and the whole process is inhibited.
