Uncovering the Lipid Interface in Neurotransmission: Single Molecule Measurements of Neurotransmitters Interacting with Membranes Reveal Species Dependent Membrane Binding

open access: yesAdvanced Science, EarlyView.
Using single‐molecule whispering gallery mode sensors, neurotransmitter‐specific membrane binding signatures are measured that reveal intrinsically distinct interaction kinetics and orientations on a lipid membrane. Abstract Neurotransmitters (NTs) have traditionally been understood to act via aqueous‐phase receptor binding, but growing evidence ...

Astrocytes are mainly responsible for the polyunsaturated fatty acid enrichment in blood–brain barrier endothelial cells in vitro

open access: yesJournal of Lipid Research, 1998
To determine the respective roles of endothelial cells from brain capillaries and astrocytes in the conversion of circulating 18:2n–6 and 18:3n–3 into 20:4n–6 and 22:6n–3, respectively, a coculture of the two cell types mimicking the in vivo blood–brain ...

Pirin Transcriptionally Regulates PLA2G4A To Inhibit Ferroptosis in Colorectal Cancer via Lipid Profile Remodeling

open access: yesAdvanced Science, EarlyView.
This study identifies Pirin (PIR), an iron‐binding protein, as a critical ferroptosis suppressor in colorectal cancer through lipid membrane remodeling. PIR, induced by NRF2 during ferroptotic stress, transcriptionally regulates PLA2G4A to shift cellular lipid composition away from ferroptosis‐permissive polyunsaturated phospholipids.

Boron Nitride Nanomaterials Trigger Immunomodulatory Effects in Human Broncho‐Epithelial Cells by Modulating Eicosanoid Lipid Signaling

open access: yesAdvanced Science, EarlyView.
This study demonstrates that BNNT exposure disrupts lipid homeostasis in bronchial epithelial cell cultures and activates eicosanoid lipid biosynthesis, producing inflammatory lipid mediators like leukotrienes. These effects are more pronounced in asthmatic cell cultures compared to healthy ones.

Alternative Pathway for Methyl Supply through the Coupling of SHMT1 and PEMT to Maintain Astrocytic Homeostasis in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
In Parkinson's disease, SHMT1 downregulation disrupts its interaction with PEMT in astrocytes, reducing SAM levels. This leads to H3K4me1 hypomethylation and decreased Slc1a2/Glul expression, ultimately exacerbating neuroexcitotoxicity and dopaminergic neuron loss.

Metabolism‐Regulating Nanomedicines for Cancer Therapy

open access: yesAdvanced NanoBiomed Research, EarlyView.
This review highlights metabolism‐regulating nanomedicines designed to target glycolytic, lipid, amino acid, and nucleotide pathways in tumors. By incorporating metabolism‐regulating agents into versatile nanocarriers such as liposomes, micelles, dendrimers, and engineered bacteria, these platforms achieve targeted delivery, controlled release ...

Insufficient glucose supply is linked to hypothermia upon cold exposure in high-fat diet-fed mice lacking PEMT[S]

open access: yesJournal of Lipid Research, 2015
Mice that lack phosphatidylethanolamine N-methyltransferase (Pemt−/− mice) are protected from high-fat (HF) diet-induced obesity. HF-fed Pemt−/− mice show higher oxygen consumption and heat production, indicating that more energy might be utilized for ...
