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 ...
Plasma membrane calcium ATPase activity is regulated by actin oligomers through direct interaction
(American Society for Biochemistry and Molecular Biology, 2013-08)
As recently described by our group, plasma membrane calcium ATPase (PMCA) activity can be regulated by the actin cytoskeleton. In this study, we characterize the interaction of purified G-actin with isolated PMCA and examine ...
Morphology and histochemistry of glandular trichomes in Hyptis villosa Pohl ex Benth. (Lamiaceae) and differential labeling of cytoskeletal elements
(Soc Botanica Brasil, 2017-07-01)
Lamiaceae contains many species known for their aromatic properties that are produced by the production of essential oils in glandular trichomes. Hyptis is one of the most common genera of Lamiaceae in the Brazilian flora, ...
Regulation of cytoskeletal dynamics by redox signaling and oxidative stress: implications for neuronal development and trafficking
(Frontiers Media, 2015)
A proper balance between chemical reduction and oxidation (known as redox balance)
is essential for normal cellular physiology. Deregulation in the production of oxidative
species leads to DNA damage, lipid peroxidation ...
The actin/spectrin membrane-associated periodic skeleton in neurons
(Frontiers Research Foundation, 2018-05)
Neurons are the most asymmetric cell types, with their axons commonly extending over lengths that are thousand times longer than the diameter of the cell soma. Fluorescence nanoscopy has recently unveiled that actin, ...
Actin filaments-A target for redox regulation
(John Wiley and Sons Inc., 2016-10)
Actin and its ability to polymerize into dynamic filaments is critical for the form and function of cells throughout the body. While multiple proteins have been characterized as affecting actin dynamics through noncovalent ...
Pouterin, a novel potential cytotoxic lectin-like protein with apoptosis-inducing activity in tumorigenic mammalian cells
(Pergamon-elsevier Science LtdOxfordInglaterra, 2008)
Actin cytoskeleton-dependent and -independent host cell invasion by Trypanosoma cruzi is mediated by distinct parasite surface molecules
(Amer Soc Microbiology, 2006-10-01)
The disassembly of host cell actin cytoskeleton as a facilitator of Trypanosoma cruzi invasion has been reported by some authors, while other workers claim that it instead inhibits internalization of the parasite. in this ...
Super-resolution imaging of live sperm reveals dynamic changes of the actin cytoskeleton during acrosomal exocytosis
(Company of Biologists, 2018-11)
Filamentous actin (F-actin) is a key factor in exocytosis in many cell types. In mammalian sperm, acrosomal exocytosis (denoted the acrosome reaction or AR), a special type of controlled secretion, is regulated by multiple ...
