Machine Learning-Designed Cell-Penetrating Peptide Boosts Antibody-Drug Conjugate Cancer Killing by Enhancing Lysosomal Delivery

NCR peptide delivered >4x more EGFP into cells than TAT peptide and accumulated in lysosomes. Domain Z-NCR vector non-covalently bound T-DM1 and significantly enhanced its cytotoxicity against HER2-positive tumor cells (MTT assay) while maintaining drug specificity for HER2-expressing cells.

Cell-Penetrating Peptides TAT and 8R Enhance Virus-Like Particle Delivery With Distinct Tissue Targeting — TAT to Lungs, 8R to Brain

Both TAT and 8R CPPs significantly enhanced P22 VLP cellular uptake in vitro and tissue accumulation in vivo. At 24 hours post-injection, TAT-conjugated VLPs showed superior lung distribution and retention, while 8R-conjugated VLPs showed better brain accumulation. TAT was overall superior for cellular uptake and tissue accumulation.

Antimicrobial Peptide Microneedle Patches Eradicate Wound Biofilms — Including in Diabetic Wounds

W379 + anti-PBP2a co-loaded microneedle patches reduced bacteria from ~3.31×10⁷ to 1.28×10² CFU/mL in 2 hours in vitro. Ex vivo: ~7.18 log CFU reduction after one application within 48 hours. In vivo (diabetic mouse): bacterial colonies undetectable after two treatments within 48 hours. No evident cytotoxicity.

Systematic Review: GLP-1 Drugs May Reduce Alcohol Consumption, But High-Quality Evidence Is Limited

Exenatide RCT: no significant reduction in heavy drinking days vs placebo overall (95% CI -7.4 to 19.4, p=0.37), but fMRI showed reduced brain reward center cue reactivity in obese subgroup. Dulaglutide secondary analysis: 29% more likely to reduce alcohol intake (relative effect 0.71, CI 0.52-0.97, p=0.04). Observational studies showed fewer alcohol-related healthcare events with GLP-1 RAs.

How Peptides Could Transform Treatment of Genetic Disorders

Peptides are emerging as versatile tools for treating genetic disorders through multiple mechanisms beyond just acting as drugs. The review identifies three key roles for peptides in this space: 1. **Direct therapeutics**: A limited but growing number of peptide-based drugs treat genetic disorders, with several more in clinical trials. Most current therapies provide symptomatic relief rather than addressing the underlying genetic defect. 2. **Gene delivery carriers**: Peptides can serve as vehicles to deliver gene therapy payloads (corrective DNA or RNA) to target cells, overcoming delivery challenges that have limited gene therapy. 3. **Diagnostic tools**: Peptide-based biomarkers can detect specific mutations, and peptide vaccines are being explored as treatments for certain genetic conditions. The review maps the mechanistic underpinnings of various genetic disorders and identifies where peptide-based approaches could be most beneficial.

Substance P Neuropeptide Enhances Collagen Production in Corneal Wound Healing via TGF-β Signaling

Substance P had no independent effect on corneal fibroblast collagen synthesis or MMP-1 expression. However, it significantly enhanced TGF-β-induced collagen type I synthesis. This effect was mediated by p38 MAPK activation and was blocked by neurokinin-1 receptor inhibition. SP did not affect IL-1β-stimulated MMP-1 expression.

Bacteriocins: Why Bacteria's Own Antimicrobial Peptides Haven't Reached the Clinic Yet

Bacteriocins are a diverse class of antimicrobial peptides produced by bacteria that show strong potential as alternatives to conventional antibiotics. Despite nearly a century of research, no bacteriocin has been approved for therapeutic use in humans — they remain limited to food preservation applications like nisin. The review catalogs the broad structural diversity of bacteriocins, from simple linear peptides to extensively post-translationally modified structures. Their mechanisms of action include membrane disruption, pore formation, and inhibition of cell wall synthesis. Crucially, many bacteriocins have narrow-spectrum activity, meaning they can target specific pathogens while leaving beneficial gut bacteria intact — a major advantage over broad-spectrum antibiotics. Modern tools including metagenomic mining and bioengineering are accelerating the discovery and optimization of novel bacteriocins, but translation from lab to clinic has been stalled by challenges in formulation, stability, and regulatory pathways.

Real-World PRRT in 104 NET Patients: Small Bowel Tumors Respond Best, But Serious Toxicities Include Liver Failure and Nephrotic Syndrome

74% completed all 4 PRRT cycles; 18% objective response rate. Small bowel NETs: median TTF 37.3 months vs pancreatic NETs 13.2 months (p=0.001). Independent predictors of TTF: Ki-67, primary site, liver tumor burden ≥50%. ~40% had grade ≥3 AEs. 10% discontinued for treatment-related AEs. 2 delayed nephrotic syndrome cases. 6 patients had rapid liver failure progression.

Switching Between CGRP Antibody Classes May Help Migraine Patients Who Don't Respond to Their First CGRP Drug

53 migraine patients switched between CGRP mAb classes (CGRP/R to CGRP/L or CGRP/L to CGRP/R). Both switch cohorts showed some clinical improvements. Safety was maintained — adverse events from the first antibody did not recur or worsen after switching classes. Fremanezumab was not included due to UAE unavailability.

GLP-1 Drugs Treat Colitis by Reshaping Gut Bacteria and Boosting Immune Cell IL-22 Production

GLP-1RAs ameliorated DSS-induced colitis in both wild-type and T/B-cell-deficient mice via ILC3-dependent IL-22 production. Effect abolished in ILC3-deficient mice. GLP-1RAs increased Firmicutes/Proteobacteria (especially L. reuteri) and decreased pathogenic Staphylococcus. The metabolite DMS was enriched and independently ameliorated colitis while promoting IL-22+ILC3s.

GLP-1 Peptide Exendin-4 Excites Memory-Related Brain Neurons Through a Newly Identified Ion Channel Mechanism

Exendin-4 significantly increased spontaneous firing rate of hippocampal CA1 neurons. The GLP-1 receptor antagonist exendin(9-39) decreased baseline firing, indicating endogenous GLP-1 modulation. The excitatory effect was mediated through TRPC4/TRPC5 ion channels — the first demonstration of this mechanism for GLP-1 in the hippocampus.

Liraglutide Protects Kidneys From Ischemia Injury by Blocking Macrophage Traps and Ferroptosis via STAT3/6 Pathway

Liraglutide relieved renal ischemia-reperfusion injury and ferroptosis in vivo. It inhibited macrophage extracellular trap (MET) formation both in vivo and in vitro. Liraglutide decreased STAT1 phosphorylation and increased STAT3/6 phosphorylation, promoting M2 macrophage polarization. STAT3/6 inhibition reversed all liraglutide protective effects.

Review: Next-Generation Peptide Drugs for Obesity and Diabetes — From GLP-1 to Triple Agonists

GLP-1 RAs may face efficacy plateaus due to receptor desensitization. Tirzepatide's dual GLP-1/GIP agonism offers superior weight loss and glycemic control. Triple agonists (GLP-1/GIP/glucagon) represent the next frontier. Oral GLP-1 formulations are expanding access. Understanding intercellular signaling and inflammatory pathways is key to developing next-generation agents.

GLP-1/Estrogen Combo Outperforms Other Multi-Agonists for PCOS in Mice

GLP-1/Estrogen showed superior efficacy versus GLP-1/GIP, GLP-1/GIP/Glucagon, and metformin for metabolic complications of PCOS in mice. GLP-1/E also improved ovarian cyclicity in an ovulatory PCOS model without direct estrogenic effects on the uterus (no uterotrophic effects). Proteomics revealed GLP-1/E changes hypothalamic pathways differently between the two PCOS models, explaining variable effectiveness.

Review: The Four Families of Endogenous Opioid Peptides and Their Receptor System

Four endogenous opioid peptide families (beta-endorphin, enkephalin, dynorphin, endomorphin) act through multiple receptor types (mu, delta, kappa, ORL1). The EOS mediates pain modulation, reward behaviors, stress response, immune function, and social bonding. These systems have extensive cross-talk with other neurotransmitter and hormonal systems.

Review: How Tirzepatide's Dual GLP-1/GIP Agonism May Provide Cardiovascular Benefits Beyond Glucose Control

Tirzepatide's dual mechanism may provide cardiovascular protection through: (1) anti-inflammatory effects, (2) anti-apoptotic activity, (3) autophagy promotion, (4) atherosclerosis reduction, (5) indirect benefits via blood pressure, weight, and lipid improvements. GIP receptor activation adds mechanisms beyond GLP-1 alone. Heart failure trials are underway.
