Human erythrocytes: cytoskeleton and its origin
(Springer, 2020-05)
In the last few years, erythrocytes have emerged as the main determinant of blood rheology. In mammals, these cells are devoid of nuclei and are, therefore, unable to divide. Consequently, all circulating erythrocytes come ...
Differential Effects of G- and F-Actin on the Plasma Membrane Calcium Pump Activity
(Humana Press, 2012-11)
We have previously shown that plasma membrane calcium ATPase (PMCA) pump activity is affected by the membrane protein concentration (Vanagas et al., Biochim Biophys Acta 1768:1641-1644, 2007). The results of this study ...
Neuroprotective effects of hypothermia on synaptic actin cytoskeletal changes induced by perinatal asphyxia
(Elsevier Science, 2014-05)
Cerebral hypoxia–ischemia damages synaptic proteins, resulting in cytoskeletal alterations, protein aggregation and neuronal death. In the previous works, we have shown neuronal and synaptic changes in rat neostriatum ...
Actin filaments modulate electrical activity of brain microtubule protein two-dimensional sheets.
(Wiley Online Library, 2020-01)
The cytoskeleton of eukaryotic cells contains networks of actin filaments and microtubules (MTs) that are jointly implicated in various cell functions, including cell division, morphogenesis, and migration. In neurons, ...
The actin cytoskeleton of the mouse sperm flagellum is organized in a helical structure
(Company of Biologists, 2018-06-11)
Conception in mammals is determined by the fusion of a sperm cell with an oocyte during fertilization. Motility is one of the features of sperm that allows them to succeed in fertilization, and their flagellum is essential ...
The actin cytoskeleton participates in the early events of autophagosome formation upon starvation induced autophagy
(Landes Bioscience, 2012-08-06)
Autophagy is a process by which cytoplasmic material is sequestered in a double-membrane vesicle destined for degradation. Nutrient deprivation stimulates the pathway and the number of autophagosomes in the cell increases ...
Extracellular Galectin-3 Induces Accelerated Oligodendroglial Differentiation Through Changes in Signaling Pathways and Cytoskeleton Dynamics
(Humana Press, 2019-01)
Galectin-3 (Gal-3) is a chimeric protein structurally composed of unusual tandem repeats of proline and short glycine-rich segments fused onto a carbohydrate recognition domain. Our studies have previously demonstrated ...
Proteomic analysis of the parasitic Cnidarian Ceratonova shasta (Cnidaria: Myxozoa) reveals diverse roles of actin in motility and spore formation
(Frontiers Media, 2021-04)
Myxozoans are widely distributed aquatic obligate endoparasites that were recently recognized as belonging within the phylum Cnidaria. They have complex life cycles with waterborne transmission stages: resistant, infectious ...
The metalloprotease Mpl supports Listeria monocytogenes dissemination through resolution of membrane protrusions into vacuoles
(American Society for Microbiology, 2016-06)
Listeria monocytogenes is an intracellular pathogen that disseminates within the intestinal epithelium through acquisition of actin-based motility and formation of plasma membrane protrusions that project into adjacent ...
