Although it is widely recognized that disruption of ALS3 reduces the invasion of Candida albicans germ tubes into mammalian oral epithelial cells, the mechanism of this interaction was unexplored. C.

On the dynamics of the microfilament system in HeLa cells [PDF]
We measured the pools of unpolymerized and filamentous actin in homogenates of HeLa cells made in several different lysis buffers, as well as after treatment of cells with a variety of chemicals or trypsin, and after adenovirus (type 2) infection.

Comparison of whole blood versus red blood cells and plasma to correct trauma-induced coagulopathy ex vivo. [PDF]
Abstract Background Early resuscitation is based on platelet‐poor components such as red blood cells and plasma (RBC + P), contributing to platelet dilution and worsening of trauma‐induced coagulopathy (TIC). We aimed to compare the ability of cold‐stored whole blood (WB) versus RBC + P as a single component to correct TIC.

The kinetics of cytochalasin D binding to monomeric actin. [PDF]
It has been shown previously, using G-actin labeled with N-iodoacetyl-N'-(5-sulfo-1-naphthyl)ethylene-diamine, that Mg2+ induces a conformational change in monomeric G-actin as a consequence of binding to a tight divalent cation binding site (Frieden, C. (1982) J. Biol. Chem. 257, 2882-2886).

α1A-adrenergic receptor induces activation of extracellular signal-regulated kinase 1/2 through endocytic pathway. [PDF]
G protein-coupled receptors (GPCRs) activate mitogen-activated protein kinases through a number of distinct pathways in cells. Increasing evidence has suggested that endosomal signaling has an important role in receptor signal transduction.

The Human Fungal Pathogen Cryptococcus neoformans Escapes Macrophages by a Phagosome Emptying Mechanism That Is Inhibited by Arp2/3 Complex-Mediated Actin Polymerisation [PDF]
The lysis of infected cells by disease-causing microorganisms is an efficient but risky strategy for disseminated infection, as it exposes the pathogen to the full repertoire of the host's immune system.

TGFβ is a potent regulator of several biological functions in many cell types, but its role in the differentiation of human bone marrow-derived skeletal stem cells (hMSCs) is currently poorly understood. In the present study, we demonstrate that a single

Examination of actin and microtubule dependent APC localisations in living mammalian cells [PDF]
(provisional) Background The trafficking of the adenomatous polyposis coli (APC) tumour suppressor protein in mammalian cells is a perennially controversial topic. Immunostaining evidence for an actin-associated APC localisation at intercellular

Continuous, label-free, 96-well-based determination of cell migration using confluence measurement
Cellular migration is essential in diverse physiological and pathophysiological processes. Here, we present a protocol for quantitative analysis of migration using confluence detection allowing continuous, non-endpoint measurement with minimal hands-on ...

Trogocytosis by Entamoeba histolytica Mediates Acquisition and Display of Human Cell Membrane Proteins and Evasion of Lysis by Human Serum. [PDF]
We previously showed that Entamoeba histolytica kills human cells through a mechanism that we termed trogocytosis ("trogo-" means "nibble"), due to its resemblance to trogocytosis in other organisms. In microbial eukaryotes like E.
