Special Issue Information

Dear Colleagues,

Chronic kidney disease (CKD) is a global public health problem affecting people from all segments of society. The renal glomerulus (in particular, the filtration barrier) is the main target of these disorders. Its structure constitutes a special and unique microenvironment whose integrity is maintained by the molecular interaction between three central components: the endothelial cell, the basement membrane and the podocytes. This architecture must be finely preserved because its destabilization, through extraordinarily complex molecular mechanisms, can lead to the onset of severe proteinuria. This structural complexity limits the availability of reliable experimental models. Recent advances in regenerative medicine, organoids, as well as the design of microfluidic platforms or other devices, constitute promising models for the study of CKD.

This Special Issue is a continuation of a previous issue on this topic. It will serve as a report on the state of basic and translational research in the field of nephrotic syndrome pathogenesis: molecular mechanisms and new experimental models.

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. Biomedicines 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 2600 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.

Diabetic nephropathy (DN) is the leading cause of end-stage kidney disease. Increasing evidence has suggested that inflammation is a key microenvironment involved in the development and progression of DN. Studies have confirmed that macrophage accumulation is closely related to the progression to human DN. Macrophage phenotype is highly regulated by the surrounding microenvironment in the diabetic kidneys. M1 and M2 macrophages represent distinct and sometimes coexisting functional phenotypes of the same population, with their roles implicated in pathological changes, such as in inflammation and fibrosis associated with the stage of DN. Recent findings from single-cell RNA sequencing of macrophages in DN further confirmed the heterogeneity and plasticity of the macrophages. In addition, intrinsic renal cells interact with macrophages directly or through changes in the tissue microenvironment. Macrophage depletion, modification of its polarization, and autophagy could be potential new therapies for DN. Full article
