Actin Filament Depolymerization01:19

Actin Filament Depolymerization

3.0K
Actin filaments (F-actin) are composed of actin subunits. The dissociation of actin monomers can occur from either end of F-actin. The rate of dissociation is faster from the minus-end or the pointed end, where the actin subunits exist with a bound ADP, together known as ADP-actin. The depolymerization of F-actin is aided by proteins, including the actin-depolymerizing factor (ADF) and cofilin family of proteins, gelsolin, and glia maturation factor (GMF).
In F-actin, the ADF/cofilin proteins...

Mechanism of Filopodia Formation

2.4K
Filopodia are thin, actin-rich cellular protrusions that play an important role in many fundamental cellular functions. They vary in their occurrence, length, and positioning in different cell types, suggesting their diverse roles.
Their main function is to guide migrating cells during normal tissue morphogenesis or cancer metastasis by recognizing and making initial contacts with the extracellular matrix. However, they can also act as stationary cell anchors or help to establish communication...

Area of Science:

  • Soft Matter Physics
  • Materials Science
  • Liquid Crystal Physics

Background:

  • Ferroelectric nematic liquid crystals (FNLCs) are emerging functional soft materials.
  • They combine nematic liquid crystal orientational order with spontaneous electrical polarization.
  • Unlike conventional nonpolar nematics, FNLCs form thinning liquid filaments.

Purpose of the Study:

  • To investigate the thinning dynamics of freely suspended ferroelectric nematic liquid crystal filaments.
  • To understand the mechanical properties and rheological behavior of FNLCs.
  • To explore the contribution of polar order to the mechanical response of nematic phases.

Main Methods:

  • Utilized videomicroscopy to observe filament thinning.
  • Performed rheological measurements to characterize material properties.
  • Analyzed the two-stage thinning dynamics (elastocapillary and visco-elastocapillary regimes).

Main Results:

  • FNLC filaments exhibit a distinct two-stage thinning process before rupture.
  • The FNLC material behaves as an elastic liquid with a significant extensional relaxation time.
  • Mechanical response is strongly influenced by long-range polar order.

Conclusions:

  • FNLCs display unique mechanical behavior distinct from conventional liquid crystals.
  • Findings provide fundamental insights into the mechanics of polar nematic phases.
  • Electrically tunable control of flow and morphology in FNLCs is a promising avenue.
