The polyphosphoinositide phosphodiesterase of erythrocyte membranes [PDF]

Biochemical Journal, 1981
1. A new assay procedure has been devised for measurement of the Ca2+-activated polyphosphoinositide phosphodiesterase (phosphatidylinositol polyphosphate phosphodiesterase) activity of erythrocyte ghosts. The ghosts are prepared from cells previously incubated with [32P]Pi.

Imaging morphological details and pathological differences of red blood cells using tapping-mode AFM [PDF]

, 2004
The surface topography of red blood cells (RBCs) was investigated under nearphysiological conditions using atomic force microscopy (AFM). An immobilization protocol was established where RBCs are coupled via molecular bonds of the membrane glycoproteins ...

The C-terminal portion of the cleaved HT motif is necessary and sufficient to mediate export of proteins from the malaria parasite into its host cell [PDF]

, 2013
The malaria parasite exports proteins across its plasma membrane and a surrounding parasitophorous vacuole membrane, into its host erythrocyte. Most exported proteins contain a Host Targeting motif (HT motif) that targets them for export. In the parasite

Estimating the sensitivity of mechanosensitive ion channels to membrane strain and tension [PDF]

, 2004
Bone adapts to its environment by a process in which osteoblasts and osteocytes sense applied mechanical strain. One possible pathway for the detection of strain involves mechanosensitive channels and we sought to determine their sensitivity to membrane ...

Erythrocyte membranes in metabolic syndrome

Problems of Endocrinology, 2009
The authors discuss results of investigations into the structure and functional status of erythrocyte membranes in patients with metabolic syndrome. It is shown that the pathological process involves not only well known changes in serum lipid metabolism but also highly specialized cells, such as erythrocytes.

Membrane proteins in senescent erythrocytes [PDF]

Biochemical Journal, 1989
The examination of erythrocyte senescence has been facilitated by recent advances in techniques for the isolation of aged red cells. One of these methods, which uses biotinylated rabbit erythrocytes, has been used to examine the state of membrane proteins in effete cells.

Erythrocyte Membrane Biophysical Changes Mediated by Pooled Immunoglobulin G and Hematin: Electrokinetic and Lipid Peroxidation Studies

, 2023
Pooled Immunoglobulin G (IgG), hematin and the membrane-disruptive amphipathic peptide melittin have received attention as powerful biomacromolecules for biomedical and pharmacology applications.

Sub-grouping of Plasmodium falciparum 3D7 var genes based on sequence analysis of coding and non-coding regions [PDF]

, 2003
Background The variant surface antigen family Plasmodium falciparum erythrocyte membrane protein-1 (PfEMP1) is an important target for protective immunity and is implicated in the pathology of malaria through its ability to adhere to host endothelial ...

Oxidative Stress and Erythrocyte Membrane Alterations in Children with Autism: Correlation with Clinical Features.

PLoS ONE, 2013
It has been suggested that oxidative stress may play a role in the pathogenesis of Autism Spectrum Disorders (ASD), but the literature reports somewhat contradictory results.

Participation of reactive oxygen species in regulation of Са2+ - activated К + channels of erythrocytes

Бюллетень сибирской медицины, 2009
In this study, we investigated the effects of preincubation with the reactive oxygen species-generating system xanthine oxidase/xanthine on Ca2+-dependent potassium permeability of erythrocyte membrane. The increase of intracellular calcium concentration
