Using a syringe-like device, Shigella delivers an array of virulence factors into host cells to facilitate bacterial colonization and disable the host's innate immune defense. In this issue of Cell Host & Microbe, Konradt and colleagues (Konradt et al., 2011) show that Shigella also subverts adaptive immunity by targeting T cells through a mechanism involving PIP(2) breakdown.

A novel interplay between bacteria and metabolites in different early-stage lung cancer: an integrated microbiome and metabolome analysis.
Front Oncol
January 2025
Lung Cancer Center, West China Hospital, Sichuan University, Chengdu, Sichuan, China.
Background: The carcinogenesis mechanism of early-stage lung cancer (ESLC) remains unclear. Microbial dysbiosis is closely related to tumor development. This study aimed to analyze the relationship between microbiota dysbiosis in ESLC.

Objective: To establish a rapid detection method for canine using recombinase-aided amplification (RAA) technology.
Methods: The outer membrane protein 25 gene fragment (Omp25) of canis was targeted. Primers and fluorescent probes were designed and synthesized, and recombinant plasmids were constructed as standards.
Disruption of intestinal barrier and dysbiosis of gut microbiota in an experimental rhesus macaque model with 6-year diabetes mellitus.

Department of Endocrinology and Metabolism, Center for Diabetes and Metabolism Research, West China Hospital, Sichuan University.
This study aims to clarify the disruption of gut barrier and dysbiosis of the microbiota in an experimental macaque model with 6-year diabetes mellitus (DM), and provide evidence for the application of therapeutic strategies targeting the human microbiota in the future. A single intravenous injection of high-dose streptozotocin was used to induce the type 1 diabetes (T1D) macaque model. Hematoxylin-Eosin (HE) and Periodic Acid Schiff (PAS) staining were conducted to observe colon morphological changes.

Kenya Medical Research Institute- Center for Global Health Research (KEMRI-CGHR), P.O Box 1578-40100, Kisumu, Kenya.
Background: Despite the adverse health outcomes associated with longer duration diarrhea (LDD), there are currently no clinical decision tools for timely identification and better management of children with increased risk. This study utilizes machine learning (ML) to derive and validate a predictive model for LDD among children presenting with diarrhea to health facilities.
Methods: LDD was defined as a diarrhea episode lasting ≥ 7 days.
The Type III Secretion System (T3SS) of Escherichia Coli Promotes Atherosclerosis in Type 2 Diabetes Mellitus.

Large-scale studies indicate a strong relationship between the gut microbiome, type 2 diabetes mellitus (T2DM), and atherosclerotic cardiovascular disease (ASCVD). Here, a higher abundance of the type III secretion system (T3SS) virulence factors of Enterobacteriaceae/Escherichia-Shigella in patients with T2DM-related-ASCVD, which correlates with their atherosclerotic stenosis is reported. Overexpression of T3SS via Citrobacter rodentium (CR) infection in Apoe-/- T2DM mice exacerbated atherosclerotic lesion formation and increased gut permeability.
