Mechanisms of Action of Probiotics.

Advances in Nutrition, 2019
Probiotics are living microorganisms that confer health benefits to the host when administered in adequate amounts; however, dead bacteria and their components can also exhibit probiotic properties. Bifidobacterium and strains of lactic acid bacteria are

Neuroactive probiotics

BioEssays, 2011
Microbial biofilms constitute a major reason for infections to occur and persist at various sites in the human body, especially in association with medical devices. The organisms invariably form these biofilms on surfaces which have host proteins and other substances coating them.

Gemella morbillorum Promotes Colorectal Carcinogenesis: LPBDCP‐Mediated Invasion Activates Ras Signaling and Destabilizes p53

Advanced Science, EarlyView.
ABSTRACT Gut microbiota dysbiosis promotes colorectal cancer (CRC) tumorigenesis. A global fecal metagenomic analysis identified Gemella morbillorum as a key contributor to the CRC‐associated microbiota. Fluorescence in situ hybridization revealed that Gemella morbillorum is enriched in CRC tumor tissues compared to adjacent normal tissues.

A pilot study on the effects of probiotic supplementation on neuropsychological performance and microRNA-29a-c levels in antiretroviral-treated HIV-1-infected patients [PDF]

, 2017
The gut microbiota is involved in the regulation of cognition, mood, anxiety, and pain, and can impact cognitive functions by producing neuroactive substances or releasing bacterial by-products and metabolites.

Surface components and metabolites of probiotics for regulation of intestinal epithelial barrier

Microbial Cell Factories, 2020
The gut microbiota can significantly affect the function of the intestinal barrier. Some intestinal probiotics (such as Lactobacillus , Bifidobacteria , a few Escherichia coli strains, and a new generation of probiotics including Bacteroides ...

Bifidobacterium Pseudolongum‐Derived Acetate Attenuates Acute Pancreatitis Through GPR43‐Mediated Suppression of M1 Macrophage Polarization

Advanced Science, EarlyView.
The severity of acute pancreatitis (AP) is linked to reduced abundance of Bifidobacterium pseudolongum (B. pseudolongum). Administration of B. pseudolongum or its key metabolite acetate alleviates pancreatic and systemic inflammation by suppressing M1 macrophage polarization.

The potential of novel gut microbiota supplement in mitigating gut inflammation, alleviating oxidative stress linked to aging, and improving cognitive function in aged mice

BMC Complementary Medicine and Therapies
Background Aging is a physiological process that impacts multiple systems of organs. Alzheimer’s disease (AD) is the most common form of dementia in the elderly, and it is a major problem in aging societies.

A three-plasmid-containing CRISPR-Cas9 platform to engineer Bacillus velezensis 916 as an efficient biocontrol agent

Applied and Environmental Microbiology
Bacillus velezensis (Bv) is a widely used biocontrol agent against plant diseases, mainly because its genome contains numerous non-ribosomal peptide synthetases (NRPS) gene clusters for the synthesis of various cyclic lipopeptides (CLPs).

Multicohort Validation of Gut Microbiome Signatures for Cholangiocarcinoma Diagnosis and Functional Characterization of Bifidobacterium Pseudocatenulatum

Advanced Science, EarlyView.
This study analyzes gut bacteria in cholangiocarcinoma patients, revealing distinct microbial signatures that enable accurate disease detection. Species‐based diagnostic models achieved over 98% accuracy in identifying cholangiocarcinoma and distinguished it from other liver diseases. The research demonstrates that specific beneficial bacteria suppress
