The Mechanics of (Poro-)Elastic Contractile Actomyosin Networks As a Model System of the Cell Cytoskeleton08:50

The Mechanics of (Poro-)Elastic Contractile Actomyosin Networks As a Model System of the Cell Cytoskeleton

1.1K
In this work, an in vitro reconstitution approach is employed to study the poroelasticity of actomyosin gels under controlled conditions. The dynamics of the actomyosin gel and the embedded solvent are quantified, through which the network poroelasticity is demonstrated. We also discuss the experimental challenges, common pitfalls, and relevance to cell cytoskeleton...

Macro-Rheology Characterization of Gill Raker Mucus in the Silver Carp, Hypophthalmichthys molitrix

3.5K
This protocol presents a method to perform rheology characterization of mucus that resides on gill rakers (GRs) of the silver carp. Viscoelastic characteristics of GR-mucus, obtained by measuring viscosity, storage and loss moduli, are evaluated for the apparent yield stress to understand the filter feeding mechanism in...

An Analog Macroscopic Technique for Studying Molecular Hydrodynamic Processes in Dense Gases and Liquids

9.0K
An experimentally accessible analog method for studying molecular hydrodynamic processes in dense fluids is presented. The technique uses particle image velocimetry of vibrated, high-restitution grain piles and allows direct, macroscopic observation of dynamical processes known and predicted to exist in strongly interacting, high density gases and...

Confocal Imaging of Confined Quiescent and Flowing Colloid-polymer Mixtures

12.5K
Confocal microscopy is used to image quiescent and flowing colloid-polymer mixtures, which are studied as model systems for attractive suspensions. Image analysis algorithms are used to calculate structural and dynamic metrics for the colloidal particles that measure changes due to geometric...

Resumen
Este resumen es generado por máquina.

Se ha reexaminado la entrada del virus de la inmunodeficiencia humana (VIH) en las células huésped. Los nuevos hallazgos sugieren que el VIH utiliza principalmente la endocitosis, desafiando el modelo de fusión directa de larga data.

Área de la Ciencia:

  • Virología Virología.
  • Biología celular Biología celular.
  • Inmunología Inmunología.

Sus antecedentes:

  • El virus de la inmunodeficiencia humana (VIH) se ha estudiado tradicionalmente como un virus que entra en las células huésped a través de la fusión directa con la membrana plasmática.
  • Este modelo de entrada viral ha sido ampliamente aceptado y aplicado a otros virus envueltos.

Objetivo del estudio:

  • Para investigar el mecanismo primario de la entrada del VIH en las células huésped.
  • Desafiar el modelo establecido de fusión directa de la membrana plasmática para la entrada del VIH.

Principales métodos:

  • El estudio realizado por Miyauchi et al. (2009) utilizó imágenes avanzadas y ensayos celulares para observar las interacciones entre las células huésped y el VIH.
  • Se emplearon inhibidores específicos y manipulaciones genéticas para diseccionar la vía de entrada viral.

Principales resultados:

  • La evidencia convincente indica que el VIH entra en las células predominantemente a través de la endocitosis.
  • Los hallazgos sugieren que la fusión directa en la membrana plasmática no es la ruta principal para la infección por el VIH.

Conclusiones:

  • El modelo prevaleciente de entrada del VIH requiere una revisión.
  • Comprender la vía endocítica del VIH es crucial para desarrollar nuevas estrategias antivirales.
