Glutamate Receptor Signaling in Retina Müller Cells: Plausible Role in Neurodegeneration

Receptors
The retinal network relies on glutamate, the primary excitatory neurotransmitter involved in the visual cycle. Glutamate transactions are carried out by an array of distinct receptors and transporters distributed across both pre- and post-synaptic ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

A Robust and Rapid Method of Producing Soluble, Stable, and Functional G-Protein Coupled Receptors [PDF]

, 2011
Membrane proteins, particularly G-protein coupled receptors (GPCRs), are notoriously difficult to express. Using commercial E.coli cell-free systems with the detergent Brij-35, we could rapidly produce milligram quantities of 13 unique GPCRs ...

Short‐chain mono‐carboxylates as negative modulators of allosteric transitions in Gloeobacter violaceus ligand‐gated ion channel, and impact of a pre‐β5 strand (Loop Ω) double mutation on crotonate, not butyrate effect

Physiological Reports
Using the bacterial proton‐activated pentameric receptor‐channel Gloeobacter violaceus ligand‐gated ion channel (GLIC): (1) We characterize saturated, mono‐carboxylates as negative modulators of GLIC (as previously shown for crotonate; Alqazzaz et al ...

Evaluation of [¹²⁵I]α-Bungarotoxin Binding to α7 Nicotinic Acetylcholinergic Receptors in Hippocampus–Subiculum of Postmortem Human Alzheimer’s Disease Brain

Receptors
Background/Objectives: Alzheimer’s disease (AD) severely hinders cognitive function in the hippocampus (HP) and subiculum (SUB), impacting the expression of nicotinic acetylcholine receptors (nAChRs) such as the α7-subtype.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Nuclear Hormone Receptors and Their Ligands: Metabolites in Control of Transcription

, 2020
Nuclear hormone receptors are a family of transcription factors regulated by small molecules derived from the endogenous metabolism or diet. There are forty-eight nuclear hormone receptors in the human genome, twenty of which are still orphans.

Somatic loss of estrogen receptor beta and p53 synergize to induce breast tumorigenesis

Breast Cancer Research, 2017
Background Upregulation of estrogen receptor beta (ERβ) in breast cancer cells is associated with epithelial maintenance, decreased proliferation and invasion, and a reduction in the expression of the receptor has been observed in invasive breast tumors.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
