UCP2 Upregulates ACSL3 to Enhance Lipid Droplet Release from Acinar Cells and Modulates the Sirt1/Smad3 Pathway to Promote Macrophage‐to‐Myofibroblast Transition in Chronic Pancreatitis

open access: yesAdvanced Science, EarlyView.
These findings suggest that UCP2 promotes LD formation and release in acinar cells by upregulating ACSL3 expression. This alteration in the local lipid metabolic environment indirectly drives the MMT process. Additionally, UCP2 may regulate the acetylation of Smad3 through Sirt1, enhancing its nuclear activity and activating the TGF‐β/ Smad3 signaling ...

Targeting Cystine Metabolism in the Lung Cancer Environment Enhances the Efficacy of Immune Checkpoint Inhibition

open access: yesAdvanced Science, EarlyView.
The tumor‐associated macrophages (TAMs) in lung cancer tissues exhibit active cystine metabolism. Restricting cystine concentration in macrophages induces M1 phenotypic polarization and upregulation of PD‐L1 expression through the GSH‐NF‐κB signaling pathway.

MCT1‐mediated Lactate Shuttle to Mitochondria Governs Macrophage Polarization and Modulates Glucose Homeostasis by Affecting β Cells

open access: yesAdvanced Science, EarlyView.
This study demonstrates that the transport of lactate to the mitochondria is of critical importance in determining the functions of macrophages by altering mitochondrial respiration. In macrophages, this lactate transport mechanism regulates glucose homeostasis by influencing the functions of insulin‐secreting cells in the pancreatic islets.

Dynein‐Dependent Endo‐Lysosomal Degradation Drives Lewy Body Disorders Accompanied by Aβ Pathology

open access: yesAdvanced Science, EarlyView.
This study investigates the impact of Aβ plaques on α‐synuclein (αSyn) pathologies in dementia with Lewy bodies (DLB). Co‐culturing primary neurons with AD mouse brain slices reveals impaired dynein‐dependent organelle trafficking, affecting αSyn degradation. Activating Rab7 restores this process, reducing αSyn inclusions.

An Allele of Glutamate Formiminotransferase Triggers 5‐Methyl‐Tetrahydrofolate‐to‐MeFox Conversion and Facilitates Folate Biofortification in Maize

open access: yesAdvanced Science, EarlyView.
This work demonstrates the distinct roles of the glutamate formiminotransferase (GFT) enzyme in plants. The GFT triggers the conversion of 5‐methyl‐tetrahydrofolate to MeFox in plants, a process distinct from its role as a formiminotransferase in mammals.
