TLR3 forms a highly organized cluster when bound to a poly(I:C) RNA ligand

Nature Communications, 2022
TLR3 plays a crucial role in anti-viral immune response by recognizing RNAs produced during virus infection. Here, the authors determine a high resolution structure of the activated cluster of TLR3.

Leveraging current insights on IL‐10‐producing dendritic cells for developing effective immunotherapeutic approaches

FEBS Letters, EarlyView.
In vivo IL‐10 produced by tissue‐resident tolDC is involved in maintaining/inducing tolerance. Depending on the agent used for ex vivo tolDC generation, cells acquire common features but prime T cells towards anergy, FOXP3+ Tregs, or Tr1 cells according to the levels of IL‐10 produced. Ex vivo‐induced tolDC were administered to patients to re‐establish/

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia

FEBS Letters, EarlyView.
This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

CLEC-2 Prevents Accumulation and Retention of Inflammatory Macrophages During Murine Peritonitis

Frontiers in Immunology, 2021
Platelets play a key role in the development, progression and resolution of the inflammatory response during sterile inflammation and infection, although the mechanism is not well understood.

Diphthamide synthesis is linked to the eEF2‐client chaperone machinery

FEBS Letters, EarlyView.
The diphthamide modification of eukaryotic translation elongation factor 2 (eEF2) is important for accurate protein synthesis. We addressed the potential coordination of de novo eEF2 synthesis with simultaneous or subsequent diphthamide modification. Our work reveals that the co‐chaperones Hgh1 and Cpr7, which are known to support folding of nascent ...

A novel and selective fluorescent ligand for the study of adenosine A2B receptors

Pharmacology Research & Perspectives
Fluorescent ligands have proved to be powerful tools in the study of G protein‐coupled receptors in living cells. Here we have characterized a new fluorescent ligand PSB603‐BY630 that has high selectivity for the human adenosine A2B receptor (A2BR).

Protein-induced membrane curvature changes membrane tension [PDF]

, 2014
Adsorption of proteins onto membranes can alter the local membrane curvature. This phenomenon has been observed in biological processes such as endocytosis, tubulation and vesiculation. However, it is not clear how the local surface properties of the membrane, such as membrane tension, change in response to protein adsorption.

A histidine‐rich extension of the mitochondrial F0 subunit ATP6 from the ice worm Mesenchytraeus solifugus increases ATP synthase activity in bacteria

FEBS Letters, EarlyView.
The glacier ice worm Mesenchytraeus solifugus survives year‐round at 0 °C. Its ATP6 subunit, which forms a regulatory component of the proton pore in mitochondrial ATP synthase, has a carboxy‐terminal extension not found in any other organism examined to date. Here, we show that fusion of this extension to the homologous AtpB protein in E. coli results

Mapping membrane biophysical nano-environments

Nature Communications
The mammalian plasma membrane is known to contain domains with varying lipid composition and biophysical properties. However, studying these membrane lipid domains presents challenges due to their predicted morphological similarity to the bulk membrane ...

Agonist efficacy at the β2AR is driven by the faster association rate of the Gs protein

Frontiers in Pharmacology
IntroductionThe β2-adrenoceptor (β2AR) is a class A G protein-coupled receptor (GPCR). It is therapeutically relevant in asthma and chronic obstructive pulmonary disease (COPD), where β2AR agonists relieve bronchoconstriction.
