Mechanisms of Baicalin Alleviates Intestinal Inflammation: Role of M1 Macrophage Polarization and Lactobacillus amylovorus

open access: yesAdvanced Science, EarlyView.
Baicalin alleviates E. coli‐induced intestinal inflammation through dual mechanisms: direct inhibition of the TLR4/IRF/STAT signaling pathway to modulate macrophage polarization and antigen presentation, thereby regulating Th17/Treg cell differentiation; and microbiota‐mediated indirect effects via increasing Lactobacillus amylovorus abundance and ...

Virtual Gram staining of label-free bacteria using darkfield microscopy and deep learning [PDF]

open access: yesScience Advances (2025)
Gram staining has been one of the most frequently used staining protocols in microbiology for over a century, utilized across various fields, including diagnostics, food safety, and environmental monitoring. Its manual procedures make it vulnerable to staining errors and artifacts due to, e.g., operator inexperience and chemical variations.

Small RNA Toxin‐Assisted Evolution of GC‐Preferred ErCas12a for Enhanced Genome Targeting Range

open access: yesAdvanced Science, EarlyView.
ErCas12a is engineered to target GC‐rich PAMs using a small RNA toxin‐aided positive screening system. The resulting variant, enErCas12a, exhibits an expanded PAM profile and facilitates efficient gene editing in both bacterial and mammalian cells, while preserving high targeting specificity for both canonical and non‐canonical PAM targets.

Shiga Toxin Detection Methods : A Short Review [PDF]

open access: yesarXiv, 2013
The Shiga toxins comprise a family of related protein toxins secreted by certain types of bacteria. Shigella dysenteriae, some strain of Escherichia coli and other bacterias can express toxins which caused serious complication during the infection. Shiga toxin and the closely related Shiga-like toxins represent a group of very similar cytotoxins that ...
