Characterization of the Pore Environments in Covalent Organic Frameworks by Dynamic Spin Probe Exchange

open access: yesSmall, EarlyView.
Covalent organic frameworks (COFs) with alkyl or triethylene glycol pore linings are probed with water‐dissolved nitroxide radicals using CW EPR spectroscopy. Adsorption affinity, local polarity, and radical concentration inside the pores are quantified, revealing hydrogen bonding, dipolar, and π‐π interactions that govern guest binding, which ...

Ezh2 Inhibits the Differentiation of Short‐Lived Effector CD8+ T Cells and Promotes T Cell‐Dependent Antitumor Immunity

open access: yesCancer Science, EarlyView.
The antitumor immune response is attenuated in T cell‐specific Ezh2 knockout mice. ABSTRACT Appropriate regulation of the differentiation balance between effector CD8+ T cells and memory CD8+ T cells is crucial for an appropriate immune response. We previously reported that the tumor suppressor menin suppresses the differentiation of CD8+ T cells into ...

Extracellular fluid viscosity influences the mechanics and migration of MDA‐MB‐231 cells in a macromolecule‐dependent manner

open access: yesThe FEBS Journal, EarlyView.
Macromolecule‐dependent increases in extracellular fluid viscosity alter cell phenotype. These distinct macromolecules create different extracellular environments that modulate cell morphology and mechanoprotein expression, migration and invasion capacity, and cellular mechanical properties.
