Molecular determinants of signal transduction in tropomyosin receptor kinases

open access: yesFEBS Open Bio, EarlyView.
Tropomyosin receptor kinases control critical neuronal functions, but how do the same receptors produce diverse cellular responses? This review explores the structural mechanisms behind Trk signaling diversity, focusing on allosteric modulation and ligand bias.

RIG-I agonist SLR10 promotes macrophage M1 polarization during influenza virus infection

open access: yesFrontiers in Immunology, 2023
RationaleA family of short synthetic, triphosphorylated stem-loop RNAs (SLRs) have been designed to activate the retinoic-acid-inducible gene I (RIG-I) pathway and induce a potent interferon (IFN) response, which may have therapeutic potential.

Calcium‐sensing receptor induces the apoptosis of chondrocytes in cooperation with phosphate transporter

open access: yesFEBS Open Bio, EarlyView.
Excess Ca2+ ions activate the Calcium‐Sensing Receptor (CaSR), which subsequently drives the uptake of excess inorganic phosphate (Pi) via the Pi transporter (Pit−1) in chondrocytes. This mechanism causes a toxic increase in intracellular Pi concentration, ultimately leading to chondrocyte apoptosis and pathological mineralization. Excess extracellular

cGAS–STING, an important signaling pathway in diseases and their therapy

open access: yesMedComm
Since cyclic guanosine monophosphate‐adenosine monophosphate synthase (cGAS)–stimulator of interferon genes (STING) signaling pathway was discovered in 2013, great progress has been made to elucidate the origin, function, and regulating mechanism of cGAS–

Towards an Understanding of the Mode of Action of Human Aromatase Activity for Azoles through Quantum Chemical Descriptors-Based Regression and Structure Activity Relationship Modeling Analysis

open access: yesMolecules, 2020
Aromatase is an enzyme member of the cytochrome P450 superfamily coded by the CYP19A1 gene. Its main action is the conversion of androgens into estrogens, transforming androstenedione into estrone and testosterone into estradiol.

Molecular basis for high-affinity agonist binding in GPCRs

open access: yesScience, 2018
A GPCR seen in the active state G protein–coupled receptors (GPCRs) are exceptionally good targets for drug development. Warne et al. describe four crystal structures of complexes of a GPCR—the β1-adrenergic receptor—in its active state.

Inverse Modelling to Obtain Head Movement Controller Signal [PDF]

open access: yes, 1984
Experimentally obtained dynamics of time-optimal, horizontal head rotations have previously been simulated by a sixth order, nonlinear model driven by rectangular control signals.

Oxygenation inhibits the physiological tissue-protecting mechanism and thereby exacerbates acute inflammatory lung injury [PDF]

open access: yes, 2005
Acute respiratory distress syndrome (ARDS) usually requires symptomatic supportive therapy by intubation and mechanical ventilation with the supplemental use of high oxygen concentrations.

The photoswitchable cannabinoid azo‐HU308 enables optical control of Ca2+ dynamics in INS‐1 β‐cells via off‐target effects on TRPC channels

open access: yesFEBS Open Bio, EarlyView.
Light activation of the photoswitchable cannabinoid ligand azo‐HU308 triggers Ca2+ influx in pancreatic β‐cells through TRPC channels, independent of CB2 cannabinoid receptors. This reveals a non‐GPCR pathway for cannabinoid modulation of β‐cell Ca2+ dynamics and establishes azo‐HU308 as an optical tool to study cannabinoid signaling through TRP ...
