This review provides a comprehensive overview of recent advances in bioactive peptide development for cosmetic applications. It summarizes peptide classification, biological mechanisms, production strategies, stabilization technologies, and emerging discovery platforms. By integrating synthetic biology, high-throughput screening, and artificial intelligence-driven design, this work highlights new opportunities for developing multifunctional, efficient, and next-generation peptide-based cosmetic ingredients.

A study published in Systems Microbiology and Biomanufacturing reports a significant breakthrough in the microbial production of γ-aminobutyric acid (GABA). Researchers successfully engineered a high-producing strain of Enterococcus faecalis, designated EM05, achieving a GABA titer of 64.2 g/L in a 3 L bioreactor. This was accomplished through a combinatorial strategy involving atmospheric and room temperature plasma (ARTP) mutagenesis, microdroplet cultivation (MMC) based adaptive evolution, and systematic fermentation medium optimization.

Researchers in China have designed an exploratory randomized controlled trial protocol to evaluate the safety, feasibility, and preliminary effects of a 12-month home-based strength training program delivered at three different intensities in boys with Duchenne muscular dystrophy (DMD). The findings are expected to provide critical data to guide future larger-scale trials and evidence-based exercise prescriptions.

A new mechanism based on Nuciferine, a bioactive alkaloid from lotus leaf, to ameliorate Type 2 Diabetes Mellitus-induced Cognitive Impairment (T2DM-CI) by directly targeting the Insulin Receptor (IR) and activating the PI3K/AKT signaling pathway to reduce Tau hyperphosphorylation and oxidative stress is provided, and a new strategy for metabolic-targeted neuroprotection in diabetes is opened.
