Obesity and Immunosenescence

Edited by:
Daniela Frasca: University of Miami, USA

Submission Status: Open   |   Submission Deadline: 30 June 2024


Immunity & Ageing is calling for submissions to our collection on Obesity and Immunosenescence. Aging and obesity are high risk factors for multiple conditions and diseases. The term “adipaging” recently introduced indicates that they are both associated with inflammaging, and ameliorated by a healthy life style, clearly indicating that they may have several cellular and molecular pathways and underlying mechanisms in common.

CD1d is involved in the presentation of lipids and lipoproteins to immune cells.

About the collection

Immunity & Ageing is calling for submissions to our collection on Obesity and Immunosenescence. Aging and obesity are high risk factors for multiple conditions and diseases. The term “adipaging” recently introduced indicates that they are both associated with inflammaging, and ameliorated by a healthy life style, clearly indicating that they may have several cellular and molecular pathways and underlying mechanisms in common. A close relationship between aging and obesity is also supported by the observation that aging and obesity share other features, including oxidative stress, telomere erosion, changes in microbiota composition and epigenetic changes, all associated with health issues, and recent findings have identified dietary factors as crucial modifiers of biological age.

Obesity has also been suggested to accelerate inflammaging and immunosenescence. This seems to occur through metabolic, physiologic and functional changes in immune cells leading to dysfunctional immunity. The understanding of obesity-driven dysregulated immune cell metabolism as a cause of age-associated diseases is in the spotlight because of its pivotal role already described in inflammatory-based diseases such as cancer and autoimmune diseases. However, it is still not completely understood how metabolic alterations accumulate during aging in the different immune cells.

This Immunity & Ageing collection welcomes submissions on the following topics:

◉ Obesity-driven metabolic regulation of immunosenescence  
◉ Mechanisms underpinning the crosstalk between immunity and metabolism in obesity and aging
◉ Metabolic dysregulation of immune cell homeostasis leading to obesity-associated inflammaging
◉ Nutritional and healthy life-style interventions to prevent or delay obesity-associated inflammaging

Note: all contributions must be within the scope of the collection. The journal reserves the right to reject without review out-of-scope manuscripts.

This Collection welcomes submission of Research Articles, Data Notes, Case Reports, Study Protocols, and Database Articles.

Before submitting your manuscript, please ensure you have read our submission guidelines. Articles for this collection should be submitted via our submission system, Snapp. During the submission process you will be asked whether you are submitting to a Collection, please select "Obesity and Immunosenescence" from the dropdown menu.

Articles will undergo the journal’s standard peer-review process and are subject to all of the journal’s standard policies. Articles will be added to the collection as they are published.

The Editors have no competing interests with the submissions which they handle through the peer review process. The peer review of any submissions for which the Editors have competing interests is handled by another Editorial Board Member who has no competing interests.
