Special Issue Information

Dear Colleagues, 

Various nanoparticles have recently emerged and been widely applied in drug delivery, nanomedicine, advanced diagnostic imaging fields, and cancer therapy. Nanoparticles have several merits in terms of cell-specific targeting due to their applicable nanoscale sizes. The liver is one of the most important immune organs encountering several exogenous materials entering the human body system, which means that it is also one of main target organs for nanoparticle application for treatment or diagnosis. Cell-specific targeting through nanoparticle modification is a promising strategy to treat chronic liver disease, and various target cells can be effective depending on the liver disease stage. Therefore, cell-specific targeting strategies such as liver Kupffer cells, neutrophils, sinusoidal vessel endothelial cells, hepatic stellate cells, and hepatocytes are essential to modulate various therapeutic targets in chronic liver disease as well as in liver cancer. This Special Issue welcomes any original research and reviews related to various cell specific targeting strategies, modifications, characterizations of novel nanoparticles to target various liver cells as well as modulation of various therapeutic targets using nanoparticle-based delivery systems for chronic liver disease and liver cancer.

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.

Hepatocytes comprise the majority of the liver and largely exert metabolic functions, whereas non-parenchymal cells (NPCs)—comprising Kupffer cells, dendritic cells and liver sinusoidal endothelial cells—control the immunological state within this organ. Here, we compared the suitability of two isolation methods for murine liver NPCs. Liver perfusion (LP) with collagenase/DNase I applied via the portal vein leads to efficient liver digestion, whereas the modified liver dissociation (LD) method combines mechanical dissociation of the retrieved organ with enzymatic degradation of the extracellular matrix. In cases of both LP and LD, NPCs were enriched by subsequent gradient density centrifugation. Our results indicate that LP and LD are largely comparable with regards to the yield, purity, and composition of liver NPCs. However, LD-enriched liver NPCs displayed a higher degree of activation after overnight cultivation, and accordingly were less responsive towards stimulation with toll-like receptor ligands that are frequently used as adjuvants, e.g., in nano-vaccines. We conclude that LP is more suitable for obtaining liver NPCs for subsequent in vitro studies, whereas LD as the less laborious method, is more convenient for parallel isolation of larger numbers of samples for ex vivo analysis.
