Exploring Ligand Binding to Calcitonin Gene-Related Peptide Receptors

Frontiers in Molecular Biosciences, 2021
Class B1 G protein-coupled receptors (GPCRs) are important targets for many diseases, including cancer, diabetes, and heart disease. All the approved drugs for this receptor family are peptides that mimic the endogenous activating hormones.

Diffusion of Integral Membrane Proteins in Protein-Rich Membranes

The Journal of Physical Chemistry Letters, 2017
The lateral diffusion of embedded proteins along lipid membranes in protein-poor conditions has been successfully described in terms of the Saffman-Delbrück (SD) model, which predicts that the protein diffusion coefficient D is weakly dependent on its radius R as D ∝ ln(1/R).

The Role of Chemotherapy in Pediatric Myoepithelial Carcinoma: A Systematic Review of the Literature

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Myoepithelial carcinoma (MEC) in pediatric patients is a rare and aggressive malignancy characterized by heterogeneous morphology and variable molecular features. The optimal role of chemotherapy remains unclear. We conducted a systematic review according to PRISMA 2020 guidelines to evaluate chemotherapy in pediatric and young‐adult patients ...

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).

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.

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.

Tracking Membrane Protein Association in Model Membranes

PLoS ONE, 2009
Membrane proteins are essential in the exchange processes of cells. In spite of great breakthrough in soluble proteins studies, membrane proteins structures, functions and interactions are still a challenge because of the difficulties related to their hydrophobic properties.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

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 ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
