Interaction of erythrocyte membranes with particulates.

چکیده
Chrysotile fibers promoted the fusion of human erythrocyte membranes and the hemolysis and fusion of fowl erythrocytes. Amosite and glass fibers did not show the same effect. These findings provide a model for the internalization of the fibers by animal cells.

P Nmr Studies of the Effect of Methemoglobin on Erythrocyte and Model Membranes
The importance of protein-lipid interactions [1] in modulating biological activity is becoming increasingly recognized. Among the many facets of this broad area of study, the interaction of different forms of hemoglobin with artificial lipid membranes [2] has been reported to influence both structure and dynamics of membranes C31*] • In the light of the above studies we have used P NMR to inves...
متن کاملBryszewska: Binding of normal and glycated haemoglobin to erythrocyte membranes from diabetics
The interaction between normal or glycated haemoglobin and the cytoplasmic surface of human erythrocyte ghost membranes from normal and diabetic individuals was studied at low pH and low ionic strength. Haemoglobin binding to the membrane was monitored by quenching of a fluorescent probe, 12-(9anthroyl) stearic acid, embedded in the membrane. The quenching occurs by energy transfer from the pro...
متن کاملInteraction of bovine erythrocyte spectrin with aminophospholipid liposomes.
Interaction of bovine erythrocyte spectrin with aminophospholipid (phosphatidylethanolamine, phosphatidylserine and their mixture) vesicles was studied by means of intrinsic fluorescence quenching and fluorescence polarization of 1,6-diphenyl-1,3,5-hexatriene. Similarly as human and pig erythrocyte spectrin, bovine red blood cell spectrin interacts with vesicles prepared from these phospholipid...
متن کاملErythrocyte membranes inhibit respiratory burst and protein nitration during phagocytosis by macrophages.
Phagocytosis is associated with respiratory burst producing reactive oxygen and nitrogen species. Several studies imply that erythrocytes can inhibit the respiratory burst during erythrophagocytosis. In this work we studied the mechanisms of this effect using control and in vitro peroxidized erythrocyte membranes. We demonstrated that autofluorescence of peroxidation products can be used for vi...
متن کاملCytosolic protein binding to band-3 protein inhibits endocytosis of isolated human erythrocyte membranes.
Recent studies of haemoglobin binding to the cytoplasmic side of the erythrocyte membrane have shown that the predominant high-affinity interaction occurs with the major integral membrane protein known as band-3 protein and that this interaction may occur within the intact erythrocyte in a manner regulated by cell pH. We report here that haemoglobin and glyceraldehyde 3-phosphate dehydrogenase ...
