ACAT1‐Mediated SP1‐K694 Lactylation Promotes M1 Macrophage Polarization via TREM1 Transcription in COPD

Advanced Science, EarlyView.
Upon cigarette smoke exposure(CSE), LDHA expression is increased in lung macrophages, promoting the conversion of pyruvate to lactate and elevating the lactylation level of SP1 at the K694 site. This, in turn, enhances SP1 enrichment at the TREM1 promoter, increases TREM1 expression, promoted M1 macrophage polarization, and triggers the secretion of ...

Immunomodulatory and wound-healing effects of the host defence peptide LL-37 and related innate defence regulators

, 2012
LL-37, the only known human cathelicidin peptide, possesses a variety of immunomodulatory properties that extend its role in host defence far beyond its original classification as an antimicrobial peptide.

Solution Structures of Human LL-37 Fragments and NMR-Based Identification of a Minimal Membrane-Targeting Antimicrobial and Anticancer Region

, 2016
To understand the structure and activity relationship of human LL-37, a series of peptide fragments was designed. The N-terminal fragment, LL-37(1−12), was not active, while the C-terminal fragment, LL-37(13−37), killed Escherichia coli, as well as drug ...

EphB1 Receptor Blockade Augments Morphine Antinociception via Inhibiting GRK2‐Mediated µ‐Opioid Receptor Internalization

Advanced Science, EarlyView.
Administration of opioids activates ephrinB2‐EphB1 receptor signaling. Activated EphB1 receptors induce GRK2‐mediated phosphorylation of MOR at Ser375, which initiates the internalization of MOR and reduces opioid antinociception at the behavioral level. ABSTRACT Opioids are the primary treatment for severe pain in clinical practice.

Supramolecular Assembly of an Antimicrobial Peptide Into a Pore

Angewandte Chemie, EarlyView.
Supramolecular assembly of an AMP is linked to transport across the Staphylococcus aureus membrane. ABSTRACT Antimicrobial peptides (AMPs) have long been ascribed the ability to form pores. These structures, some observed, others inferred, vary in their mechanisms of action, though most are associated with lysis.

Targeting Nupr1‐Mediated p53 Mitochondrial Sequestration Alleviates Aortic Dissection by Restoring the Gadd45b‐Dependent Survival Program

Advanced Science, EarlyView.
This study identifies Nupr1 as a crucial stress‐responsive orchestrator driving AD. Under severe stress, Nupr1 massively accumulates within mitochondria to sequester p53, triggering apoptosis and concurrently repressing the Gadd45b‐mediated survival program.

Downsizing Electrophilic MAX‐Derived Helical Zipper Peptides to Covalently Bind and Degrade Oncogenic MYC

Angewandte Chemie, EarlyView.
Oncogenic MYC is a transcription factor that is difficult to inhibit. However, precise positioning of an acrylamide electrophile in MAX to covalently bond to the unique Cys438 in MYC, enabled shortening and optimizing of MAX‐derived, helix‐constrained peptides with high‐affinity and selectivity.

Elevated LL-37/FPR2 Axis and its Regulatory Role for Gingival Fibroblasts in Periodontitis

International Dental Journal
Introduction and aims: LL-37, an antimicrobial peptide with dual pro-/anti-inflammatory roles, has been implicated in the pathogenesis of periodontitis, yet its specific action through its receptor Formyl peptide receptor 2 (FPR2) remains unclear.

Targeting Macrophage STING O‐GlcNAcylation via Small‐Molecule Allosteric Modulation for Psoriasis Therapy

Advanced Science, EarlyView.
Paeoniflorin allosterically targets the STING cyclic dinucleotide‐binding domain, stabilizes an inactive open conformation, and disrupts STING–OGT interaction to reduce Thr229 O‐GlcNAcylation and downstream signaling. This mechanism restrains myeloid STING activation, alleviates psoriasis‐like inflammation, and is supported by analyses of patient ...
