Why use mouse in science


Why use animal models?
In syndrome analysis, animal models offer a valuable tool to fill the gap in information regarding altered brain mechanisms that result in the manifestation of activity deficits characteristic of syndrome spectrum disorder (ASD).

Generation of animal models for ASD, depends on findings evolving from genetic and environmental studies, thatinform United States of America regarding the insults liable for the ASD constitution. Insults (e.g., genetic mutation) area unit mimicked within the species of option to model the deficits we tend to observe in people with ASD and to permit a organized investigation of altered mechanisms at the molecular, cellular, and brain level.
For example, studies in animal models will address questions on the biological effects of a particular modificationon (1) the strength of interaction between nerve cells (known as junction plasticity), (2) the integrity of communication between brain regions that employment along to control specific behavior (known as brain circuits) and (3) on psychological feature, motor and social behaviors. Answers to those queries offer the platform for future studies centered on drug discovery and development

Animal models are getting used for testing translatable biomarkers, that area unit measures that may be assessed comparably in each human and animal subjects. Once known, these biomarkers will function tools to look at the efficaciousness of potential medical specialty in animal models, predict their impact in human subjects, and inform clinical trials.

Research at the Seaver syndrome Center
At the Seaver syndrome Center for analysiswe tend to area unit characterizing mouse and rat models with mutations in many ASD risk genes, as well as within the SHANK3, resulting in Phelan McDermid Syndrome (PMS) and within the FMR1 sequenceresulting in Fragile X syndrome. By taking the approach represented on top ofwe tend to discovered that treatment with IGF-1 during a mouse model with a mutation within the Shank3 sequenceameliorates junction physical property and motor deficits.

These findings shaped the idea of clinical trials with IGF-1 in people with PMS, that established the feasiblenessof IGF-1 treatment in PMS, providing proof of idea to advance information regarding developing targeted treatments for the junction disfunction related to ASD.

Another example comes from our recent study on a rat model for ASD, the Shank3-deficient rat, that additionallyharbors a mutation within the Shank3 sequence. These rats exhibit social behavior and basic cognitive processdeficits, recapitulating the medical specialty options of PMS. the character of the model’s deficits junction rectifierUnited States of America to check the impact of the pro-social internal secretion, oxytocin, on the junction physical property and activity deficits.

We found endocrine considerably improved social memory, attention, and junction physical property deficits, suggesting that endocrine might have therapeutic potential for each social and non-social deficits in people with PMS, supporting our in progress clinical trials with endocrine in these people. At the middlewe tend to arevictimization this model to develop electroencephalogram-based (EEG) biomarkers that we are able to use in future studies to check the efficaciousness of novel medical specialty.

Stem Cells
The study of stem cells has additionally gained tons of attention in syndrome analysis. Stem cells will begenerated from blood or skin samples and be differentiated to nerve cells, that area unit examined within thelaboratory. Stem cells-derived nerve cells overcome the difficulty of restricted access to living neurons, alter the identification of altereted molecular and cellular mechanisms, and permits for testing of drug effciancy at the individual level.
