Special Issue Information
Dear Colleagues,
Pulmonary hypertension (PH) comprises a group of severe clinical disorders, including pulmonary arterial hypertension (PAH), classified according to the World Health Organization (WHO) as Group 1 of PH. PAH is a chronic, progressive, and incurable disease of multifactorial pathobiology. PAH is characterized by vasoconstriction of the pulmonary vessels, an increase in pulmonary vascular resistance, and vascular tone. The remodeling in PAH is associated with endothelial cell dysfunction and intimal thickening, enhanced proliferation and a reduction in apoptosis of pulmonary smooth muscle cells, loss of pre-capillary arteries, perivascular inflammation, an increase in extracellular matrix deposition, and adventitial fibrosis. All of these processes cumulatively contribute to the progressive obliteration of the precapillary vessels, leading to an increase in pulmonary arterial pressure, right ventricular hypertrophy (RV), dysfunction, and death. The RV is the major determinant of functional state and prognosis in PAH. Plentiful molecular mechanisms contribute to the development of PAH and RV failure, including, in particular, an imbalance of vasoactive mediators, increased secretion of cytokines and chemokines, modulation of the activity of various growth factors, mitochondrial dysfunction, and changes in membrane receptors and ion channels. This Special Issue focuses on molecular mechanisms in PAH and RV hypertrophy and failure. We cordially welcome submissions, including original papers and reviews, on this broad topic.

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. 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.
