Hippocampal‐Specific Insulin Resistance Elicits Synaptic Effects on Glutamate Neurotransmission

open access: yesJournal of Neurochemistry, Volume 169, Issue 6, June 2025.
In animals with hippocampal‐specific insulin resistance, reduced vGluT2 and synaptophysin expression resulted in lowered synaptic glutamate concentrations. These animals also exhibited reduced serine phosphorylation of GluA1 (green postsynaptic receptor) and reduced expression of GluN2B (purple postsynaptic receptor).

Altered Vesicular Acetylcholine Transporter Expression Regulates Acetylcholine Abundance in the Brain of Drosophila melanogaster

open access: yesJournal of Neurochemistry, Volume 169, Issue 6, June 2025.
The vesicular acetylcholine transporter (VAChT) packages and transports the neurotransmitter acetylcholine (ACh) into synaptic vesicles for exocytosis, and its activity is necessary for essential life functions such as locomotion and cognition. Yet, the mechanism through which this important protein mediates ACh release is not fully understood. Here we

Loss of Pathogenicity and Evidence of Horizontal Gene Transfer in Colletotrichum gloeosporioides From a Medicinal Plant

open access: yesMolecular Plant Pathology, Volume 26, Issue 6, June 2025.
A Colletotrichum gloeosporioides strain from Huperzia serrata lacks key pathogenicity genes CgDN3 and cap20 and has fewer pelB, pnl and pg genes. pksIII, for synthesis of huperzine A, was probably acquired by the host plant from the fungus. ABSTRACT Colletotrichum gloeosporioides is a major agricultural pathogen of crops that has also been identified ...

Elucidating the enzyme network driving Amaryllidaceae alkaloids biosynthesis in Leucojum aestivum

open access: yesPlant Biotechnology Journal, Volume 23, Issue 6, Page 1988-2005, June 2025.
Schematic representation of Amaryllidaceae alkaloid biosynthesis in Leucojum aestivum. Norbelladine synthase (LaNBS) and noroxomaritidine/norcraugsodine reductase (LaNRII) catalyze the condensation of tyramine and 3,4‐dihydroxybenzaldehyde to form norbelladine, which is subsequently O‐methylated by norbelladine‐4′‐O‐methyltransferase (LaN4′OMT ...

Chemoenzymatic Total Synthesis of Lansai B

open access: yesChemistry – A European Journal, Volume 31, Issue 26, May 8, 2025.
Lansai B was obtained in a chemoenzymatic approach from the small building block 5‐bromoindole utilizing two enzymes. Applying a tryptophan synthase and a further characterized C3‐methyltransferase the sterically demanding framework is constructed within just six steps. After late‐stage Suzuki‐coupling and n‐methylation the natural product was isolated.
