Special Issue Information

Dear Colleagues,

Microbiome-engineered therapeutics hold considerable promise to target a variety of diseases through beneficial modulation of the gut microbiota composition and function. The use of probiotics to manipulate the microbiome and gastrointestinal (GI) environment is an attractive option to restore microbial homeostasis and host health. Although numerous probiotic formulations are still early in development or pre-clinical testing, some have proven clinically significant by promoting the abundance of beneficial microbes and metabolites, reducing inflammation, and improving systemic health while acting as a safe alternative to pharmacotherapies. Their suitability for therapeutic applications is attributed to strain-specific bioactivities, prolonged GI transit colonization, formulation preparation, probiotic form, and dosage, among several other factors.

This Special Issue will explore the latest progress in the use of probiotics to modulate the microbiome for therapeutic indications and the underlying mechanisms. You are invited to contribute to this Special Issue of the International Journal of Molecular Sciences, titled “Microbiome Modulation Through Probiotics: Molecular Insights and Therapeutic Applications.” This Special Issue will focus on the utility of microbiome-engineered therapies in the prevention, treatment, or management of disease, and their requirements for clinical translation.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Idiopathic male infertility is characterized by increased mortality or reduced motility and vitality of sperm. There are several reports on probiotics in the male reproductive tract, but the effects of these probiotics on sperm motility remain to be elucidated. In this study, we investigated the impact and mechanism of probiotics on the vitality and motility of mouse sperm. We collected mature sperm from the caudal vas deferens of mice and prepared three probiotics donated by HEM Pharma Inc.: Lacticaseibacillus rhamnosus, Limosilactobacillus fermentum, and Lacticaseibacillus paracasei. We analyzed the vitality and motility of sperm according to the concentration and duration of probiotic treatment. The probiotics increased the motility and vitality of sperm. Specifically, they enhanced sperm motility by 30–40% compared with untreated sperms. The probiotics enhanced mitochondrial activity in sperm through specific factors like AMPK and SIRT1. All three probiotics enhanced the activities of mitochondrial function-related proteins in sperm. In conclusion, we found that the probiotics improved the vitality and motility of mouse sperm and increased mitochondrial function in mature sperm. These findings suggest that probiotics can be utilized to enhance sperm motility and treat male infertility. Full article
