Special Issue Information

Dear Colleagues,

Microcirculation represents an entity that comprises the terminal vascular network including arterioles, capillaries, venules, and initial lymphatic vessels. Microcirculation maintains tissue health and function by regulating blood flow, oxygen delivery, and nutrient exchange. Pathological changes in the microcirculation, or microangiopathy, play a pivotal role in end-organ dysfunction and diseases previously thought to be caused by macrocirculatory abnormalities. Disturbances of microvascular function precede macrovascular damage. Microcirculatory dysfunction is recognized as the earliest manifestations of cardiovascular, metabolic, and neurodegenerative diseases. Despite its importance, microcirculatory dysfunction is often overlooked in clinical practice due to limitations in available diagnostic tools. However, recent advances in imaging and analytical techniques have shed new light on the structure and function of small vessels, revealing the key role of microcirculation in the pathogenesis of various diseases.

In this Special Issue, we aim to explore the molecular and cellular mechanisms underlying microcirculatory dysfunction and its contribution to the development and progression of cardiovascular, metabolic, and neurodegenerative diseases. We will also discuss the latest diagnostic modalities and potential therapeutic strategies aimed at improving microvascular function. By bringing together experts from diverse fields, we hope to provide novel insights into the complex interplay between microcirculation and disease, and stimulate further research in this exciting and rapidly evolving field.

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.

Abstract
Endothelial cells line at the most inner layer of blood vessels. They act to control hemostasis, arterial tone/reactivity, wound healing, tissue oxygen, and nutrient supply. With age, endothelial cells become senescent, characterized by reduced regeneration capacity, inflammation, and abnormal secretory profile. Endothelial senescence [...] Read more.
Endothelial cells line at the most inner layer of blood vessels. They act to control hemostasis, arterial tone/reactivity, wound healing, tissue oxygen, and nutrient supply. With age, endothelial cells become senescent, characterized by reduced regeneration capacity, inflammation, and abnormal secretory profile. Endothelial senescence represents one of the earliest features of arterial ageing and contributes to many age-related diseases. Compared to those in arteries and veins, endothelial cells of the microcirculation exhibit a greater extent of heterogeneity. Microcirculatory endothelial senescence leads to a declined capillary density, reduced angiogenic potentials, decreased blood flow, impaired barrier properties, and hypoperfusion in a tissue or organ-dependent manner. The heterogeneous phenotypes of microvascular endothelial cells in a particular vascular bed and across different tissues remain largely unknown. Accordingly, the mechanisms underlying macro- and micro-vascular endothelial senescence vary in different pathophysiological conditions, thus offering specific target(s) for therapeutic development of senolytic drugs.
