Special Issue Information

Dear Colleagues,

Cellular and molecular studies of the adrenal gland focus on understanding the structure, function, and development of the cortex and medulla, as well as the intricate signaling pathways that regulate hormone production and cell–cell communications. Recent studies highlight the importance of spatial transcriptomics, single-cell analysis, and developmental studies in unraveling the complexities of adrenal biology and physiology. 

Key areas of study in adrenal encompass adrenal zonation and differentiation, cellular heterogeneity and interactions, signaling pathways, development and differentiation, steroidogenesis, adrenal disorders, and adrenal research tools, methods, and innovations. These research areas highlight the vast and complex nature of the study of the adrenal gland, emphasizing its importance in understanding and treating endocrine and related metabolic disorders and development of new therapeutic agents.

Adrenal Physiology and Function

  1. Adrenal Zonation and Differentiation:

Studies are being conducted on how the adrenal cortex maintains its distinct functional zones, adrenal cortex (glomerulosa, fasciculata, and reticularis layers), and medulla and how cells differentiate within these zones. Spatial transcriptomics, which maps gene expression in specific locations within the gland, is providing valuable insights into these processes. 

  1. Cellular Heterogeneity and Interactions:

Studies are examining the diverse cell types within the adrenal gland and how they interact with each other via paracrine and autocrine signaling. This involves mechanistic understanding of the roles of different cell clusters and their responses to stress, hormones, and other stimuli. 

  1. Signaling Pathways:

In particular, the adrenal gland relies on various signaling pathways, including WntSHH, and cAMP/PKA, to regulate steroidogenesis and cell fate. Understanding how these pathways are activated and coordinated is crucial for understanding both normal adrenal function and disease development. 

  1. Development and Differentiation:

Studying the development of the adrenal gland, ranging from its embryonic origins to adult homeostasis, helps to identify the cellular and molecular mechanisms that underline its formation and regeneration. This includes understanding the roles of stem/progenitor cells and the signaling pathways involved in these processes. 

  1. Steroidogenesis:

A major focus is on the molecular mechanisms of steroid hormone synthesis, including the enzymes and regulatory factors involved in each step of the process. This knowledge is essential for understanding and treating disorders like congenital adrenal hyperplasia (CAH)

  1. Adrenal Disorders:

Research is also directed at understanding the cellular and molecular basis of adrenal diseases, such as adrenal insufficiency (Addison’s disease) primary hyperaldosteronism (Conn’s syndrome), Cushing's syndrome, adrenal cancer, pheochromocytomas and paragangliomas, and congenital adrenal hyperplasia. This includes identifying genetic mutations, aberrant signaling pathways, and abnormal cellular behavior that contribute to these conditions. 

  1. Adrenal Research Tools, Methods, and Innovations:

These approaches involve stem cell research, identifications of biomarkers, genetics of adrenal gland disorders, development of novel cell and animal models for adrenal research, and development of new therapeutic agents in the clinical management of adrenal-related disorders.

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. 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.
