Ampk regulates IgD expression but not energy stress with B cell activation. [PDF]

open access: yes, 2019
Ampk is an energy gatekeeper that responds to decreases in ATP by inhibiting energy-consuming anabolic processes and promoting energy-generating catabolic processes.

Lactylation‐Driven YTHDC1 Alleviates MASLD by Suppressing PTPN22‐Mediated Dephosphorylation of NLRP3

open access: yesAdvanced Science, EarlyView.
In MASLD, YTHDC1 undergoes increased lactylation and ubiquitination, reducing its expression. AARS1 mediates lactylation at lysine 565, while disrupted binding to LDHA further promotes lactylation, suppressing YTHDC1. This downregulation enhances PTPN22 mRNA stability, leading to NLRP3 dephosphorylation and activation, which exacerbates inflammation ...

Aromatic Monomer Analysis by UHPLC-MS/MS v1

open access: yes, 2023
An analysis method was developed to allow for quantitation of aromatic compounds by ultra high pressure liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) detection. This was achieved by using reverse phase chromatography and multiple reaction monitoring (MRM) in negative ion mode using electrospray ionization (ESI).

Desorption electrospray ionization-high resolution mass spectrometry for the screening of veterinary drugs in cross contaminated feddstuffs [PDF]

open access: yes, 2016
In this study, a desorption electrospray ionization-high resolution mass spectrometry (DESI-HRMS) screening method was developed for fast identification of veterinary drugs in cross-contaminated feedstuffs. The reliable detection was performed working at

Alkyltriphenylphosphonium Binding to Cardiolipin Triggers Oncosis in Cancer Cells

open access: yesAdvanced Science, EarlyView.
Alkyltriphenylphosphonium, exemplified by TPP+‐C14, preferentially accumulates in mitochondria and selectively binds to cardiolipin, a key phospholipid of the inner mitochondrial membrane, causing loss of mitochondrial membrane potential, severe cellular ATP depletion, and calcium imbalance.

Extracellular Vesicles of Streptococcus anginosus Mediate Gastritis via Epithelial Barrier Disruption and Macrophage‐driven Inflammation

open access: yesAdvanced Science, EarlyView.
Streptococcus anginosus extracellular vesicles (SA‐EVs) accumulate in gastric tissue, disrupt epithelial tight junctions, and induce gastritis characterized by neutrophil infiltration and elevated cytokines (TNF‐α, IL‐6, IL‐17A). Proteomics identifies TMPC and FBP62 as key SA‐EVs virulence factors; their genetic deletion attenuates inflammation ...

Initial B Cell Activation Induces Metabolic Reprogramming and Mitochondrial Remodeling. [PDF]

open access: yes, 2018
B lymphocytes provide adaptive immunity by generating antigen-specific antibodies and supporting the activation of T cells. Little is known about how global metabolism supports naive B cell activation to enable an effective immune response.
