Gating properties and surface trafficking of AMPA receptors (AMPARs) are modulated by auxiliary subunits. Here we studied the function of coexpressed auxiliary subunits belonging to two different classes. We focused on TARP γ-8 and CKAMP44 in dentate gyrus (DG) granule cells, since both subunits are highly expressed in this cell type. TARP γ-8 and CKAMP44 decrease the rate of deactivation but h...

This review covers areas where our understanding of the mechanisms underlying nanoindentation has been increased by atomistic studies of the nanoindentation process. While such studies have been performed now for more than 20 years, recent investigations have demonstrated that the peculiar features of nanoplasticity generated during indentation can be analyzed in considerable detail by this tec...

We identified cell surface markers associated with repression of p16(INK4a)/cyclin-dependent kinase inhibitor 2A(CDKN2A), a critical determinant in the acquisition of a plastic state. These cell surface markers allowed direct isolation of rare cells from healthy human breast tissue that exhibit extensive lineage plasticity. This subpopulation is poised to transcribe plasticity markers, OCT3/4, ...

Different cues present in the cellular environment control basic biological processes. A previously established 3D microwell array was used to study dimensionality-related effects on osteogenic differentiation and plasticity of marrow stromal cells. To enable long-term culture of single cells in the array a novel surface functionalization technique was developed, using the principle of subtract...

A gradient-extended two-surface damage-plasticity model based on a von Mises yield criterion has been proposed by [1, 2], which can be flexibly adapted to (quasi-)brittle-like, ductile-like, or various material behaviors in between. However, the does not take into account effect of hydrostatic pressure, therefore it hardly failure behavior pressure-sensitive materials such as geomaterials and s...
