Special Issue Information

Dear Colleagues,  

Brown adipose tissue (BAT) is a thermogenic organ specialized in dissipating energy through uncoupled respiration to produce heat. In addition to this classical role, recent studies have revealed that BAT also functions as an endocrine organ, releasing signaling molecules that mediate crosstalk with other metabolically active tissues, such as the liver, skeletal muscle, and heart. These interactions have been identified in both human and animal studies, which report significant correlations between BAT activity and systemic metabolic regulation. Emerging therapeutic strategies targeting BAT—particularly those focusing on its secreted factors, functional heterogeneity, and regulatory mechanisms—offer promising avenues for advancing our understanding of adipose tissue biology and for developing novel interventions for metabolic disorders. This Special Issue of the International Journal of Molecular Sciences, titled “Regulation of Brown Adipose Function,” invites original research articles and comprehensive reviews that provide novel insights into the molecular mechanisms, physiological roles, and therapeutic potential of BAT. Articles on comparisons of BAT with white adipose tissue and the beiging of white adipose tissue are also invited. Additional topics include the role of BAT in mediating healthful longevity, enhancing exercise performance, and protecting against obesity and diabetes, hypothermia, myocardial ischemia, heart failure, angiogenesis, hypertension, and cancer.  Submissions involving the use of cellular systems, animal models, or human subjects, including clinical studies, are all welcome.

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 250 words) can be sent to the Editorial Office for assessment.

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.

Brown adipose tissue (BAT) and beige adipocytes play a crucial role in adaptive thermogenesis, primarily via uncoupling protein 1 (UCP1)-driven heat production. Once considered physiologically irrelevant in adults, BAT is now recognized as an active tissue that contributes to energy expenditure and metabolic homeostasis and represents a potential therapeutic target for obesity and metabolic disorders. This review provides an integrated overview of the molecular regulation of thermogenic adipocytes, emphasizing both canonical UCP1-dependent as well as non-canonical UCP1-independent mechanisms of heat generation. Key transcriptional and epigenetic regulators are discussed in the context of mitochondrial biogenesis, substrate utilization, and thermogenic gene programs. Major upstream signaling routes are further summarized, encompassing classical β-adrenergic pathways, as well as alternative regulatory nodes including AMP-activated protein kinase (AMPK) and mechanistic target of rapamycin (mTOR) together with diverse nutrient- and hormone-responsive cues that converge to activate brown and beige adipocytes. Finally, the cross-talk among neuronal, endocrine, immune, and gut microbiota-derived signals is highlighted as a key determinant of thermogenic adipocyte function. Together, these multilayered regulatory inputs provide a comprehensive framework for understanding how thermogenic adipose tissue integrates environmental, metabolic, and microbial cues to regulate systemic energy balance—knowledge that is essential for developing targeted therapies to combat obesity and metabolic diseases.
