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 papers will be 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. Viruses 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 1600 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.
The below list represents only planned manuscripts. Some of these manuscripts have not been received by the Editorial Office yet. Papers submitted to MDPI journals are subject to peer-review.

Abstract: Prion diseases, such as Creutzfeldt–Jakob disease, have been traditionally considered to be caused by a separate class of infectious agents. The pathologically misfolded prion protein can catalyze the conversion of its natively folded counterpart into the toxic form; therefore forming a recruiting seed for protein misfolding that may spread intercellularly until the entire tissue is infected. The transmission is thought to occur through an ongoing release and uptake of exosomes, small membranous vesicles used by both neurons and astrocytes for cell-to-cell communication. Recent discoveries expand the prion field, to include prion-like proteins implicated in other neurodegenerative diseases, including Alzheimer's, Parkinson's, Huntington's, amyotrophic lateral sclerosis, and the tauopathies. In addition to sustaining an intracellular recruitment, misfolding of prion-like proteins may also spread intercellularly, a process that is implied by the systematic spread of neurodegeneration. This pattern of infectivity suggests intercellular mechanisms of communications involving exosomes or continuous exchange of inclusions containing the disease specific infectious prion-like proteins. The goal of this review was twofold: to summarize the current state of knowledge of the prion-like proteins in neurodegenerative diseases and to examine their potential mechanisms of transmission.
