The mechanisms of calcium homeostasis and signalling in the lens [PDF]

open access: yes, 2008
Excessive Ca2+ can be detrimental to cells and raised levels of Ca2+ in human lenses with cortical cataract have been found to play a major role in the opacification process.

Integrative Roles of Pro‐Inflammatory Cytokines on Airway Smooth Muscle Structure and Function in Asthma

open access: yesImmunological Reviews, Volume 330, Issue 1, March 2025.
ABSTRACT Asthma has become more appreciated for its heterogeneity with studies identifying type 2 and non‐type 2 phenotypes/endotypes that ultimately lead to airflow obstruction, airway hyperresponsiveness, and remodeling. The pro‐inflammatory environment in asthma influences airway smooth muscle (ASM) structure and function.

Hippocampal Inhibitory Interneuron‐Specific DREADDs Treatment Alters mTORC1‐4E‐BP Signaling and Impairs Memory Formation

open access: yesJournal of Neurochemistry, Volume 169, Issue 3, March 2025.
We used advanced tools called DREADDs (Designer Receptors Exclusively Activated by Designer Drugs) to control the activity of inhibitory neurons versus excitatory neurons in the hippocampus, a region of the brain critical for learning and memory. By activating or inactivating these neurons after training, we found that disrupting their normal activity ...

Neurocardiology: translational advancements and potential

open access: yesThe Journal of Physiology, Volume 603, Issue 7, Page 1729-1779, 31 March 2025.
Abstract figure legend Afferent signalling pathways of the autonomic nervous system and their efferent targets in the heart, kidneys and vasculature. Abstract In our original white paper published in the The Journal of Physiology in 2016, we set out our knowledge of the structural and functional organization of cardiac autonomic control, how it ...

Boundary lipids of the nicotinic acetylcholine receptor: spontaneous partitioning via coarse-grained molecular dynamics simulation [PDF]

open access: yesarXiv, 2018
Reconstituted nicotinic acetylcholine receptors (nAChRs) exhibit significant gain-of-function upon addition of cholesterol to reconstitution mixtures, and cholesterol affects organization of nAChRs within domain-forming membranes, but whether nAChR partitions to cholesterol-rich liquid-ordered ("raft" or $l_o$) domains or cholesterol-poor liquid ...

Opening a hydrophobic gate: the nicotinic acetylcholine receptor as an example [PDF]

open access: yesarXiv, 2009
To what extent must a hydrophobic gate expand for the channel to count as open? We address this question using the nicotinic acetylcholine receptor (nAChR) as the exemplar. The nAChR is an integral membrane protein which forms a cation selective channel gated by neurotransmitter binding to its extracellular domain.

Characterization of a new muscarinic toxin from the venom of the Brazilian coral snake Micrurus lemniscatus in rat hippocampus [PDF]

open access: yes, 2011
AimsWe have isolated a new muscarinic protein (MT-Mlα) from the venom of the Brazilian coral snake Micrurus lemniscatus.Main methodsThis small protein, which had a molecular mass of 7,048Da, shared high sequence homology with three-finger proteins that ...

M3 muscarinic acetylcholine receptors regulate epithelial–mesenchymal transition, perineural invasion, and migration/metastasis in cholangiocarcinoma through the AKT pathway

open access: yesCancer Cell International, 2018
Background Cholangiocarcinoma is a highly malignant tumor type that is not sensitive to radiotherapy or chemotherapy due to aggressive perineural invasion and metastasis.

Using molecular dynamics for the refinement of atomistic models of GPCRs by homology modeling [PDF]

open access: yes, 2017
Despite GPCRs sharing a common seven helix bundle, analysis of the diverse crystallographic structures available reveal specific features that might be relevant for ligand design.
