Special Issue Information

Dear Colleagues,

Oxidative stress and inflammation are two interconnected processes, playing a crucial role in physiological and pathological conditions, such as aging and cancer. Oxidative stress is generated by an imbalance between the production of reactive oxygen species (ROS) and antioxidant defenses, leading to damaged cells, proteins and DNA. This damage accelerates the aging process and increases the risk of developing cancer. In turn, chronic inflammation appears when the activation of the immune system is maintained over time. This state promotes the growth and spread of cancer cells, as well as contributes to age-related impairments. Moreover, oxidative stress can trigger inflammation, and chronic inflammation can lead to the establishment of the redox imbalance. Both processes can further exacerbate the aging-related manifestations and cancer development. Based on that, growing interest in developing therapeutic strategies targeting oxidative stress and inflammation against aging consequences and cancer are being reported. Antioxidant and anti-inflammatory drugs, as well as natural interventions, such as lifestyle modifications (diet and exercise) have shown promising results in reducing oxidative stress and inflammation, thereby exhibiting the potential of slowing down the aging process and reducing the risk of cancer.

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. Biomolecules is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). 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.

There is evidence of the effect of probiotic intake on the immune system. However, the effect probiotics may have on the rate of aging is unknown. The aim of this study is to determine the effect of a probiotic blend on immunity, redox state, inflammation, and the rate of aging or biological age. A group of 10 men and 14 women took, daily for 2 months, a sachet with three probiotics (Bifidobacterium animalis subsp. lactis BSO1, Lactobacillus reuteri LRE02, Lactobacillus plantarum LP14) and vitamin D. Before starting the treatment and after 2 months, peripheral blood was collected. Immune functions were assessed in isolated immune cells, and cytokine concentrations were also measured both in mononuclear cell cultures and plasma. Redox state parameters were also analyzed in whole blood cells. Finally, the Immunity Clock was applied to determine the biological age. Results show that the intake of this probiotic blend in general, in both men and women, improves immunity and decreases the oxidative and inflammatory state. In addition, it rejuvenates the biological age by 10 years on average. It can be concluded that this probiotic blend could be proposed as a good strategy to slow down the aging process, and to achieve healthy aging. Full article
