Scalable carbon dioxide electroreduction coupled to carbonylation chemistry

open access: yesNature Communications, 2017
Electroreduction of CO2 to CO is a potential valorisation pathway of carbon dioxide for fine chemicals production. Here, the authors show a user-friendly device that couples CO2 electroreduction with carbonylation chemistry for up to gram scale synthesis

Myosin IIa Promotes Antibody Responses by Regulating B Cell Activation, Acquisition of Antigen, and Proliferation

open access: yesCell Reports, 2018
Summary: B cell responses are regulated by antigen acquisition, processing, and presentation to helper T cells. These functions are thought to depend on contractile activity of non-muscle myosin IIa.

Inherited immunodeficiencies associated with proximal and distal defects in T cell receptor signaling and co-signaling

open access: yesBiomedical Journal, 2022
T lymphocytes are central cells of adaptive immunity. Activation of T lymphocytes by the antigen receptor of T cells (TCR) and co-stimulatory molecules involve specific signaling components and cascades.

Deep evolutionary conservation of an intramolecular protein kinase activation mechanism [PDF]

open access: yes, 2012
DYRK-family kinases employ an intramolecular mechanism to autophosphorylate a critical tyrosine residue in the activation loop. Once phosphorylated, DYRKs lose tyrosine kinase activity and function as serine/threonine kinases.

Development of a novel light-up probe for detection of G-quadruplexes in stress granules

open access: yesScientific Reports, 2022
G-quadruplexes (G4s) regulate various biological processes in cells. However, cellular imaging of dynamically forming G4s in biomolecular condensates using small molecules has been poorly investigated. Herein, we present a fluorescent light-up probe with

CD95 co-stimulation blocks activation of naive T cells by inhibiting T cell receptor signaling [PDF]

open access: yes, 2009
CD95 is a multifunctional receptor that induces cell death or proliferation depending on the signal, cell type, and cellular context. Here, we describe a thus far unknown function of CD95 as a silencer of T cell activation.

Cooperative redox activation for carbon dioxide conversion

open access: yesNature Communications, 2016
While CO2 can be converted to CO for further reactivity, typically this involves the generation of large amounts of waste. Here the authors report the conversion of CO2to CO, with the siloxane by-product being further used in a carbonylative Hiyama ...

Voluntary activation of human knee extensors measured using transcranial magnetic stimulation [PDF]

open access: yes, 2009
The aim of this study was to determine the applicability and reliability of a transcranial magnetic stimulation twitch interpolation technique for measuring voluntary activation of a lower limb muscle group.

Tethering of vesicles to the Golgi by GMAP210 controls LAT delivery to the immune synapse

open access: yesNature Communications, 2019
The immune synapse at the interface between T cells and antigen-presenting cells manifests intense vesicular trafficking, but how the vesicles are sorted is still unclear.

Not All Immune Checkpoints Are Created Equal

open access: yesFrontiers in Immunology, 2018
Antibodies that block T cell inhibition via the immune checkpoints CTLA-4 and PD-1 have revolutionized cancer therapy during the last 15 years. T cells express additional inhibitory surface receptors that are considered to have potential as targets in ...
