Special Issue Information
Dear Colleagues,
The microbiome, which consists of a diverse group of bacteria, viruses, archaea, and other microbes present in different regions of the body—primarily in the gut, oral cavity, and skin—forms a symbiotic relationship with its host, playing a significant role in overall health. The composition and interactions of the microbiome are shaped by an individual’s lifestyle and environmental, genetic, and sociodemographic factors throughout life, highlighting its dynamic nature. While aging is a universal process, its impact on physical and intellectual functions varies widely and is influenced by these factors. The microbiome emerges as a crucial element in the progression of age-related health decline and the development of various non-communicable diseases during aging. Chronic low-grade inflammation, often associated with aging and age-related diseases, is frequently triggered by dysregulation of the microflora. This microbiome dysregulation, especially within the gut microbiome, exposes the host to metabolites that influence the inflammatory system, leading to harmful crosstalk between the gut barrier, oral mucosal barrier, and the immune system. This interaction contributes to chronic low-grade inflammation and overall health deterioration. The intricate connection between microbiome dysbiosis and age-related diseases lies in the communication between the microbiome, mucosal barriers, and the systemic immune system, which are closely interconnected.
In this Special Issue, we invite studies that explore the microbiome’s connections with various age-related diseases, including cardiovascular disease, inflammatory bowel disease, obesity, diabetes, musculoskeletal disorders, Alzheimer’s, and dementia. Additionally, we seek to address the potential of restoring microorganisms through lifestyle and dietary interventions to enhance life expectancy and promote healthy aging. This collection of studies aims to uncover the mechanisms by which the microbiome influences aging and to identify strategies to improve health outcomes in older populations.

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.
