Galacto-Oligosaccharides : production, properties, applications, and significance as prebiotics [PDF]

open access: yes, 2010
Galacto-oligosaccharides (GOS) have now been definitely established as prebiotic ingredients after in vitro and animal and human in vivo studies. Currently, GOS are produced by glycoside hydrolases (GH) using lactose as substrate.

A Dual‐Targeting T6SS DNase Drives Bacterial Antagonism and Eukaryotic Apoptosis via the cGAS‐STING‐TNF Axis

open access: yesAdvanced Science, EarlyView.
The bacterial Type VI secretion system (T6SS) emerges as a sophisticated virulence mechanism, leveraging the dual‐function effector TkeA from Yersinia pseudotuberculosis. TkeA concurrently damages rival bacteria and host cell DNA, triggering the host's cGAS‐STING‐TNF pathway and inducing apoptosis.

Comparative transcriptomics reveals key differences in the response to milk oligosaccharides of infant gut-associated bifidobacteria. [PDF]

open access: yes, 2015
Breast milk enhances the predominance of Bifidobacterium species in the infant gut, probably due to its large concentration of human milk oligosaccharides (HMO). Here we screened infant-gut isolates of Bifidobacterium longum subsp.

Tβ4‐Engineered ADSC Extracellular Vesicles Rescue Cell Senescence Through Separable Microneedle Patches for Diabetic Wound Healing

open access: yesAdvanced Science, EarlyView.
A separable microneedle patch is designed for Tβ4–modified ADSC‐derived extracellular vesicles delivery. The overexpressed Tβ4 released from the microneedles can mitigate cellular senescence and promote wound healing via the PTEN/PI3K/AKT pathway, offering a promising approach for diabetic wound treatment. This bioengineered therapeutic system serve as

EGFR‐TKIs Induced DPP4 Drives Metabolic Reprogramming of Persister Cells in Lung Cancer

open access: yesAdvanced Science, EarlyView.
Drug‐tolerant persister (DTP) cells emerge early during EGFR‐TKI treatment, preceding the development of acquired resistance. Elevated DPP4 in DTP cells drives metabolic reprogramming and antioxidant adaptation, promoting cell survival under drug pressure.
