Special Issue Information

Dear Colleagues,

General and abdominal obesity can directly affect the immune system, and these changes can contribute to an increased susceptibility to autoimmune rheumatic diseases. Adipose tissue can become severely dysfunctional with excess increases in body weight, causing the accumulation of myeloid and lymphoid cells and changes in the extracellular matrix. Furthermore, there is an imbalance in the secretion of adipokines, increased levels of oxidative stress, and changes in the inflammatory state of immune cells infiltrating the adipose tissue itself—a situation that can be independently worsened by an unhealthy diet and sedentary lifestyle. Furthermore, the accumulation of excessive body fat can make it difficult to resolve disease-induced inflammation by increasing Th17 cell differentiation, decreasing T cells, and reducing the synthesis of TGF-beta, favoring the development of autoimmune diseases and contributing to their progression. This Special Issue of Cells invites researchers to contribute with original studies and review articles covering the state-of-art regarding experimental (in vitro and in vivo), preclinical, and translational research that enrich our understanding of the pathological role of dysfunctional adipocytes in the development and the progression of autoimmune diseases. Research fields include any aspect involving key cells, molecular pathways, and molecular interactions, including strategies for the prevention and treatment of adiposity-targeted autoimmune rheumatic diseases.

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. Cells is an international peer-reviewed open access semimonthly 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.

Adipose tissue has functions beyond its principal functions in energy storage, including endocrine and immune functions. When faced with a surplus of energy, the functions of adipose tissue expand by mechanisms that can be both adaptive and detrimental. These detrimental adipose tissue functions can alter normal hormonal signaling and promote local and systemic inflammation with wide-ranging consequences. Although the mechanisms by which adipose tissue triggers metabolic dysfunction and local inflammation have been well described, little is known about the relationship between adiposity and the pathogenesis of chronic lung conditions, such as interstitial lung disease (ILD). In this review, we detail the conditions and mechanisms by which adipose tissue becomes dysfunctional and relate this dysfunction to inflammatory changes observed in various forms of ILD. Finally, we review the existing basic and clinical science literature linking adiposity to ILD, highlighting the need for additional research on the mechanisms of adipocyte-mediated inflammation in ILD and its clinical implications.
