Special Issue Information

Dear Colleagues,

Discoveries of pathogenic mutations in ENG and ACVRL1 for hereditary hemorrhagic telangiectasia (HHT) were reported over a quarter of a century ago.  Since then, animal studies have demonstrated that a linear signaling defect in the BMP9/10-ENG-ALK1-SMAD pathway in endothelial cells is a central driver for the pathogenesis of HHT. Genetic studies in mouse models and HHT patients have also revealed that disease manifestation—i.e., formation of the arteriovenous malformations (AVMs)—requires secondary hits, most likely in the form of biallelic loss of the relevant HHT genes, as well as proangiogenic stimuli triggered by, for instance, inflammation or healing.  However, detailed mechanisms by which the defects in this signaling pathway elicit HHT pathogenesis remain elusive, and although some progress has been made with the possible repurposing of anti-angiogenic and anti-proliferative drugs, an effective cure is still out of reach. Specifically, the downstream signaling mediators and effector genes of this signaling associated with the disease have not been clearly defined. Key cellular and biological impacts caused by the signaling defect for the initiation, progression and maintenance of AVMs are also unclear. The molecular nature of the interactions of this signaling pathway with other pathways is poorly understood. Downstream targets identified from proteomics and transcriptomic studies provide insights for the development of therapeutic targets for this malady. Supplementations of physiological or synthetic ligands for ENG-ALK1 signaling are also considered for therapy. This Special Issue focuses on the research topic of molecular mechanisms underlying AVM development, progression and rupture in HHT patients, and we welcome both original research and review manuscripts.

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.
