Special Issue Information

Dear Colleagues,

Vascular biology is crucial for understanding the mechanisms behind vascular diseases in the context of cardiovascular conditions, atherosclerosis, and cancer, as well as developing effective treatments and preventive strategies. Hyperhomocysteinemia is considered to be a major risk factor for multiple diseases. These include, but are not limited to, cardiovascular disease, stroke, diabetes, obesity, hypertension, renal failure, cancer, dementia, Alzheimer's, osteoporosis, and neurological disorders. The progression of vascular diseases is a multifactorial process, including endothelial dysfunction, vascular smooth muscle cell apoptosis, proliferation, and migration from the media to the intima. Under physiological conditions, cell proliferation and apoptosis are balanced since cell death triggers cell migration and proliferation. However, in pathogenic conditions, a selective increase in cell proliferation induces hyperplasia, and a selective elevation of apoptosis leads to atrophy. Autophagy has emerged in recent years as a critical cellular survival mechanism for cell homeostasis and may play a protective role in atherosclerosis. In lipid-rich atherosclerotic areas, angiogenesis is often associated with inflammatory cells that play a role in plaque instability and rupture. Furthermore, neovascularization is a prominent feature in advanced human atherosclerotic plaques and cancer.

The objective of this Special Issue is to spotlight recent discoveries related to autophagy, hyperhomocyteinemia, alcohols, and galectins in the progression of vascular diseases and the effective therapeutic targets.

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.

Abstract
Neurodegenerative diseases, such as Alzheimer’s disease (AD), Parkinson’s disease (PD), amyotrophic lateral sclerosis (ALS), Huntington’s disease (HD), stroke, and aneurysms, are characterized by the abnormal accumulation and aggregation of disease-causing proteins in the brain and spinal cord.

Neurodegenerative diseases, such as Alzheimer’s disease (AD), Parkinson’s disease (PD), amyotrophic lateral sclerosis (ALS), Huntington’s disease (HD), stroke, and aneurysms, are characterized by the abnormal accumulation and aggregation of disease-causing proteins in the brain and spinal cord. Recent research suggests that proteins linked to these conditions can be secreted and transferred among cells using exosomes. The transmission of abnormal protein buildup and the gradual degeneration in the brains of impacted individuals might be supported by these exosomes. Furthermore, it has been reported that neuroprotective functions can also be attributed to exosomes in neurodegenerative diseases. The potential neuroprotective functions may play a role in preventing the formation of aggregates and abnormal accumulation of proteins associated with the disease. The present review summarizes the roles of exosomes in neurodegenerative diseases as well as elucidating their therapeutic potential in AD, PD, ALS, HD, stroke, and aneurysms. By elucidating these two aspects of exosomes, valuable insights into potential therapeutic targets for treating neurodegenerative diseases may be provided. Full article
