Special Issue Information

Dear Colleagues,

Zebrafish are an attractive vertebrate model used in drug discovery. Due to their small size, external development, and transparency, zebrafish embryos are compatible with multi-well plates for high-throughput screening. Based on the availability of zebrafish genome sequences, the ease of creating transgenic and genetic mutants, and the conservation of signal transduction pathways, a variety of human diseases have been modeled using zebrafish. Moreover, biological pathways, such as physiological and molecular events, which control the development and function of most organ systems, including the cardiovascular, skeletal, nervous, digestive, and visual systems of zebrafish, are similar to those in mammals. The zebrafish reference genome published in 2013 has further accelerated the use of zebrafish in human disease modeling. In the last two decades, zebrafish have become popular in pharmaceutical and toxicological research. Consequently, several drugs that have been used to treat human diseases (including tuberculosis, neuronal, and auditory disorders, as well as several types of cancer) have been identified from zebrafish screens. Such advances in this area of research have established zebrafish as an invaluable human disease model. This Special Issue aims to cover current research and provide an overview of the advances made in the area of drug discovery and disease modeling using the zebrafish model.

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.

Experimental models have been widely used to study the mechanisms of inflammation due to their genetic and physiological relevance to humans. These models include rodents (rats and mice), zebrafish, and nematodes (C. elegans). Considering the similarities and divergences between experimental models and the human organism, this narrative review aimed to compare and discuss their applicability in inflammation studies. Rodents, in particular, share significant similarities with humans across approximately 85% of their genome, making them ideal for investigating complex diseases and inflammatory responses. Zebrafish also stand out for showing high conservation of the immune system compared to humans, being useful for studies of adaptive and innate inflammation. Despite not having adaptive immunity, Caenorhabditis elegans is a robust model for understanding innate immune responses, especially in studies involving host–pathogen interactions. These organisms allow us to efficiently investigate the acute and chronic phases of inflammation, offering an accessible platform to study complex biological processes that are unfeasible in humans due to ethical and financial constraints. Thus, the use of these models has been essential for inflammation research. However, the use of each one will depend on the research question and hypothesis raised. Full article
