In retrospect, many advantages can be named, but pitfalls must also be highlighted. Rapid and cost-effective in vivo assays to screen potential environmental neurodevelopmental toxicants are necessary to address the limitations of in vitro platforms, such as the inability to fully recapitulate the developmental and physiological processes of whole organisms. Here, we review several zebrafish models of movement disorders and discuss their translational value. Zebrafish, long a useful proxy for humans in drug development, just got an upgrade courtesy of BioTek’s Lionheart FX automated microscope and Gen5 microplate reader. Zebrafish embryos are permeable to drugs and can easily be manipulated using well‐established genetic and molecular approaches. 2013;4:2410 Recently published methods facilitate genetical engineering of zebrafish, allowing the study of targets of interest in an easily accessible vertebrate system: a multiorgan culture model. 2005 Jan;4(1):35-44. doi: 10.1038/nrd1606. For the zebrafish to become useful in drug development more broadly, key hurdles must be overcome, including a more comprehensive elucidation of the similarities and differences between human and zebrafish biology. Because of all the previously described advantages that the zebrafish animal model presents, it has recently stood out in the drug discovery process (i) to identify molecules that specifically ameliorate a disease phenotype and (ii) to perform detailed characterization studies around optimized compounds, focusing not only on efficacy (dose-response) but also on toxicity and/or mechanism. Additionally, zebrafish display a repertoire of inflammatory cells, mediators, and receptors that are similar to those in mammals, including humans. Zebrafish are often exposed to a drug by dissolving the drug in the water, which enables easy and fast drug administration. 2020 Nov 19;11:599244. doi: 10.3389/fphys.2020.599244. This animal model has advantages for the discovery of anti-inflammatory drugs, such as the potential for real-time assessment of cell migration mechanisms.

This model is powerful in its breadth of application and tractability for research. Accepted: 01/09/2014 Abstract The zebrafish ( Danio rerio) has become a widely used vertebrate model organism for drug discovery because of its hi gh fecundity, transparent embryos and larvae, morphological and p hysiological similarity to mammals, allowing in vivo analysis of embryogenesis and organogenesis combined with ease of use and low cost. Front Physiol. Rubel and Raible then teamed up with Julian Simon, a molecular pharmacologist at Fred Hutchinson Cancer Research Center. Zebrafish larvae have evolved into a very attractive model for drug discovery. The zebrafish (Danio rerio) is a vertebrate with many attractive characteristics for use in drug discovery, such as a small size, transparency, gene and protein similarity with mammals (80% or more), and ease of genetic modification to establish human disease models. Bringing a new drug to the market costs an average of US$2.6 billion and takes more than 10 years from discovery to regulatory approval. The creation of mutant strains reinforces zebrafish use in inflammation research. Popular in aquariums all over the world, the zebrafish is native to South Asia. Due to their small size and relevant disease features, drugs and drug-leads can be directly screened for those that prevent or cure the disease in zebrafish These drugs are often effective in mammalian models of the disease, and some drugs identified in the zebrafish are now in clinical trial. Potential approaches to overcoming the hurdles to drug discovery in the face of complex biology including in vivoscreening of zebrafish genetic disease models. Recent studies have begun to establish the capabilities and limitations of zebrafish for disease modelling, drug screening, target identification, pharmacology, and toxicology. We are excited to be the exclusive commercial partner in Denmark, Sweden, Norway, Finland and Poland for the innovative and successful CRO company, ZeClinics - specialised in usingzebrafish for Drug Discovery and BioMedical Research. Zebrafish is a small teleost (bony) fish used in many areas of pharmacology and toxicology. 2.1. Recently, zebrafish larvae were used for detecting retinal toxicity in pharmaceutical pipeline discovery compounds, replacing studies in mammalian models and demonstrating clear value from zebrafish for drug discovery toxicology (Figure 5).
