DHA-phospholipids control membrane fusion and transcellular tunnel dynamics

J Cell Sci jcs.259119. | 08 DECEMBER 2021 Metabolic studies and animal knockout models point to the critical role of polyunsaturated docosahexaenoic acid (22:6, DHA)-containing phospholipids (PLs) in physiology. Here, we investigated the impact of DHA-PLs on the dynamics of transendothelial cell macroapertures (TEMs) triggered by RhoA inhibition-associated cell spreading. Lipidomic analyses show that human Read more about DHA-phospholipids control membrane fusion and transcellular tunnel dynamics[…]

Interactions of hydrophilic quantum dots with defect-free and defect containing supported lipid membranes

Colloids and Surfaces B: Biointerfaces Volume 210, February 2022, 112239 Quantum dots (QDs) are semiconductor nanoparticles with unique optical and electronic properties, whose interest as potential nano-theranostic platforms for imaging and sensing is increasing. The design and use of QDs requires the understanding of cell-nanoparticle interactions at a microscopic and nanoscale level. Model systems such Read more about Interactions of hydrophilic quantum dots with defect-free and defect containing supported lipid membranes[…]

Cell monolayers sense curvature by exploiting active mechanics and nuclear mechanoadaptation

Nature Physics (2021) The early development of many organisms involves the folding of cell monolayers, but this behaviour is difficult to reproduce in vitro; therefore, both mechanistic causes and effects of local curvature remain unclear. Here we study epithelial cell monolayers on corrugated hydrogels engineered into wavy patterns, examining how concave and convex curvatures affect Read more about Cell monolayers sense curvature by exploiting active mechanics and nuclear mechanoadaptation[…]

Adherent-Invasive and Non-Invasive Escherichia coli Isolates Differ in Their Effects on Caenorhabditis elegans’ Lifespan

Microorganisms 2021, 9(9), 1823 The adherent-invasive Escherichia coli (AIEC) pathotype has been implicated in the pathogenesis of inflammatory bowel diseases in general and in Crohn’s disease (CD) in particular. AIEC strains are primarily characterized by their ability to adhere to and invade intestinal epithelial cells. However, the genetic and phenotypic features of AIEC isolates vary Read more about Adherent-Invasive and Non-Invasive Escherichia coli Isolates Differ in Their Effects on Caenorhabditis elegans’ Lifespan[…]
