Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Determination of cellular strains by combined atomic force microscopy and finite element modeling [PDF]

open access: yes, 2002
Many organs adapt to their mechanical environment as a result of physiological change or disease. Cells are both the detectors and effectors of this process.

Pectin Nanostructure Visualization by Atomic Force Microscopy

open access: yesBio-Protocol, 2015
Pectins, complex polysaccharides rich in galacturonic acid, are a major component of primary plant cell walls. These macromolecules regulate cell wall porosity and intercellular adhesion, being important in the control of cell expansion and ...

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Analysis of Human Fibroblasts by Atomic Force Microscopy [PDF]

open access: yes, 2004
The force-sensing members of the large family of scanning probe microscopies have become important tools during the past decade for visualizing, characterizing, and manipulating objects and processes on the meso- and nanoscale level.

SNAREs: Could They be the Answer to an Energy Landscape Riddle in Exocytosis?

open access: yesThe Scientific World Journal, 2010
During exocytosis, chemical transmitters stored in secretory vesicles can be released upon fusion of these intracellular organelles to the plasma membrane. In this process, SNARE proteins that form a ternary core complex play a central role. This complex

High-precision atomic force microscopy with atomically-characterized tips

open access: yesNew Journal of Physics, 2020
Traditionally, atomic force microscopy (AFM) experiments are conducted at tip–sample distances where the tip strongly interacts with the surface. This increases the signal-to-noise ratio, but poses the problem of relaxations in both tip and sample that ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Functional analysis of biological matter across dimensions by atomic force microscopy (AFM): from tissues to molecules and, ultimately, atoms [PDF]

open access: yes, 2004
For a detailed understanding of biological tissues and proteins and their dynamical processes the 3D structures of the components involved must be known.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
