An important puzzle for tea consumers is which type of tea is effective in treating metabolic syndrome (MS). In this study, the effects of six types of tea extracts (TEs) on high-fat diet (HFD)-induced MS, as well as chemical components of six TEs, were investigated and compared. Each TE consisted of representative tea originated from different places in China to avoid one-sidedness of sampling. All six TEs were found to attenuate MS and ameliorate intestinal barrier function in HFD-fed rats. Further, white tea performed better in body weight control, while dark tea had more advantages in protecting intestinal barrier. Moreover, all six TEs alleviated the gut microbiota dysbiosis, which was manifested by decreased Firmicutes/Bacteroidetes ratio and enriched beneficial bacteria, such as Akkermansia, Bacteroides, and Bifidobacterium. Together, all six TEs attenuate HFD-induced MS although their efficiency varies, and this therapeutic effect is related to the modulation of gut microbiota.

Necrotizing Enterocolitis (NEC) is a severe, life-threatening inflammatory condition of the gastrointestinal tract, especially affecting preterm infants. This review consolidates evidence from various biomedical disciplines to elucidate the complex pathogenesis of NEC, integrating insights from clinical, microbial, and molecular perspectives. It emphasizes the modulation of NEC-associated inflammatory pathways by probiotics and novel biologics, highlighting their therapeutic potential.

Introduction: Colorectal cancer (CRC) is the second most common cause of cancer-related deaths globally. The gut microbiota, along with adenomatous polyps (AP), has emerged as a plausible contributor to CRC progression. This study aimed to scrutinize the impact of the FadA antigen derived from Fusobacterium nucleatum on the expression levels of the ANXA2 ceRNA network and assess its relevance to CRC advancement.

Introduction/objectives: Sjogren's syndrome (SS) is a chronic inflammatory and difficult-to-treat autoimmune disease. Timosaponin AIII (TAIII), a plant-derived steroidal saponin, effectively inhibits cell proliferation, induces apoptosis, and exhibits anti-inflammatory properties. This study explored the mechanisms of action of TAIII in SS treatment by studying gut microbiota and short-chain fatty acids (SCFAs) using fecal metabolomics.

Gut mucosal immunity of teleost is mainly governed by mucosa-associated lymphoid tissues (MALT) and indigenous microbiota on mucosal surfaces of gut tract, which can confer protection against pathogenic invasion. However, the probiotic features of bacterial isolates from gut tract of triploid cyprinid fish (TCF) were largely unclear. In this study, Lysinibacillus and Enterobacter strains were isolated for probiotic identification.

The widespread use of antibiotics has led to the emergence of multidrug-resistant bacteria, which pose significant threats to animal health and food safety. Host defense peptides (HDPs) have emerged as promising alternatives because of their unique antimicrobial properties and minimal resistance induction. However, the high costs associated with HDP production and incorporation into animal management practices hinder their widespread application.
