AI Designed Conformation Locking Peptides Target STING to Restore Diabetic Wound Healing

Advanced Science, EarlyView.
A generative AI pipeline identifies SCP‐1, a conformation‐locking peptide that stabilizes inactive STING. Incorporated into a dual‐responsive hydrogel for localized, MMP‐9‐triggered release, SCP‐1 suppresses inflammation, promotes reparative macrophage polarization, and accelerates diabetic wound healing.

Local Translation and Retrograde Axonal Transport of CREB Regulates IL-6-Induced Nociceptive Plasticity

Molecular Pain, 2014
Transcriptional regulation of genes by cyclic AMP response element binding protein (CREB) is essential for the maintenance of long-term memory. Moreover, retrograde axonal trafficking of CREB in response to nerve growth factor (NGF) is critical for the ...

GABAB receptors negatively regulate transcription in cerebellar granular neurons through cyclic AMP responsive element binding protein-dependent mechanisms.

, 1996
GABAB receptors affect short-term signalling in various cell types. However, nothing is known about possible long-term effects on transcription. To analyse such effects in the CNS, we studied GABAB receptor-mediated gene regulation in primary cultures of

Magneto‐NIR‐II‐Programmed Cascade Nanozymes Unlocking Blood–Brain Barrier Translocation and Autophagic Resistance in Glioblastoma

Advanced Science, EarlyView.
Magneto‐NIR‐II‐programmed NFSH nanozymes integrate magnetic blood–brain barrier (BBB) translocation, CD44 targeting, multimodal imaging, and cascade catalytic therapy for glioblastoma. Alternating magnetic fields and NIR‐II irradiation amplify ferroptosis, release H2S, suppress autophagic and mitophagic repair, and reshape the immune microenvironment ...

Control of PKA stability and signalling by RING ligase praja2 [PDF]

, 2010
Ligand-mediated activation of G-Protein Coupled Receptors (GPCRs) mobilises compartmentalised pulses of second messengers like cAMP. The main cellular effector of cAMP is Protein Kinase A (PKA) which is assembled as inactive holoenzyme consisting of two ...

Targeting C-terminal binding proteins (CtBPs) using genetic selection

, 2011
There are many protein-protein interactions that are vital for cellular processes such as signal transduction, structural organisation and apoptosis. In this study we decipher the role of the protein-protein interaction of C terminal Binding Proteins ...

SPTLC3 regulates plasma membrane sphingolipid composition to facilitate hepatic gluconeogenesis

Cell Reports
Summary: SPTLC3, an inducible subunit of the serine palmitoyltransferase (SPT) complex, causes production of alternative sphingoid bases, including a 16-carbon dihydrosphingosine, whose biological function is only beginning to emerge.

Senkyunolide I Inhibits mtDNA‐cGAS‐STING Signaling in Macrophages via Targeting VDAC1 Oligomerization to Attenuate Ulcerative Colitis

Advanced Science, EarlyView.
In macrophages, senkyunolide I (SEI) directly targets the K12 residue of VDAC1 to inhibit its stress‐induced oligomerization, a critical upstream event that effectively prevents mitochondrial DNA release and subsequent cGAS‐STING pathway activation.

Blood Cell‐Camouflaged Liquid Metal Nanoconjugates Orchestrate Treg Depletion and STING‐Amplified Photothermal Immunity for Metastatic Triple‐Negative Breast Cancer Therapy

Advanced Science, EarlyView.
Whole‐blood biomimetic engineering transforms liquid metal nanoparticles into a tripartite immunotherapeutic platform that orchestrates regulatory T‐cell depletion, photothermal‐induced immunogenic cell death, and activation of the stimulator of interferon genes pathway.
