Sustainable Hydrogel‐Forming Microneedle‐Reservoir Patches for Transdermal Delivery of Hydrophilic Macromolecules: Biopolymers, Green Manufacturing and Translation

open access: yesAdvanced Science, EarlyView.
Hydrogel‐forming microneedle (HFMN)‐reservoir patches provide a modular route for controlled transdermal delivery of hydrophilic biomacromolecules. The platform integrates skin‐barrier penetration, sustainable biopolymers, scalable green manufacturing, hydration‐driven transport, model‐cargo validation, and translational quality requirements.

Astrocyte‐Associated ABCA1/APOE Responses Accompany Hippocampal Lipid Remodeling and Ectopic Neuronal Accumulation During Epileptogenesis

open access: yesAdvanced Science, EarlyView.
During kainic acid‐induced epileptogenesis, astrocyte‐associated ATP‐binding cassette transporter A1 (ABCA1) and apolipoprotein E (APOE) responses accompany ectopic neurons and exploratory lipid alterations. In separate cohorts, bexarotene pretreatment and treatment on days 14–21 are associated with fewer ectopic hilar neurons and lower chronic seizure

Gut Microbiota‐Derived Indole‐3‐Acetaldehyde Contributes to the Disease‐Alleviating Effects of Kurarinone in Experimental Autoimmune Encephalomyelitis

open access: yesAdvanced Science, EarlyView.
Kurarinone ameliorates EAE via the gut microbiota‐indole‐3‐acetaldehyde‐AhR axis. Kurarinone reshapes gut microbiota and increases Akkermansia muciniphila, which promotes intestinal indole‐3‐acetaldehyde production. Indole‐3‐acetaldehyde crosses the intestinal barrier, activates AhR in CD4+ T cells, upregulates SOCS1/3, inhibits JAK2 and STAT3/4 ...

The VCPIP1‐UBE3A Deubiquitination‐Ubiquitination Cascade Contributes to Castration‐Resistant Prostate Cancer Progression

open access: yesAdvanced Science, EarlyView.
VCIPIP1 emerges as a molecular link between protein stability and prostate cancer progression. By deubiquitinating and stabilizing UBE3A, VCIPIP1 promotes p53 degradation and progression to castration‐resistant prostate cancer. Elevated VCIPIP1 expression is associated with shorter castration‐resistant prostate cancer–free survival, highlighting the ...
