Induction of Experimental Autoimmune Encephalomyelitis in a Mouse Model

In this video, a mouse model of multiple sclerosis is established using experimental autoimmune encephalomyelitis (EAE). The mouse is injected with an emulsion containing a neuronal peptide and an adjuvant, triggering an immune response that activates autoreactive T cells. This is followed by an injection of pertussis toxin (PTX) to increase blood-brain barrier permeability, allowing the autoreactive T-cells to infiltrate the brain. This infiltration initiates a signaling cascade that...

The video demonstrates the induction of experimental autoimmune encephalomyelitis in a mouse model by injecting a combination of myelin oligodendrocyte glycoproteins and inactivated Mycobacterium tuberculosis. The model enables researchers to study disease mechanisms and test therapeutic interventions.

Many investigations performed in mice (Mus musculus) require the administration of an experimental agent to the animal. For example, it may be of interest to test the efficacy of a specific therapy, to induce a pathologic condition, or to administer anesthesia or palliative care. In order to ensure safe and efficient delivery, it is important to consider a variety of factors prior to the administration of the treatment. This video, which reviews agent administration in the mouse, begins by...

This video demonstrates the method of inducing experimental autoimmune encephalomyelitis (EAE) by injecting myelin-derived peptides with an adjuvant to activate autoreactive T cells, which migrate to the brain. Pertussis toxin is administered to increase blood-brain barrier permeability, allowing these T cells and other immune cells to enter the brain. These immune cells cause demyelination, leading to impaired nerve transmission and development of EAE.

Chemical-induced Two-stage Skin Carcinogenesis Model: An Experimental In Vivo Mouse Model of Skin Cancer

This video describes the procedure to induce two-stage skin carcinogenesis to study tumor initiation by topical application of chemicals. In the first step, a mutagen, DMBA, is applied onto the skin of a mouse model which initiates tumor formation by causing mutations in the stem cells, followed by the application of a growth stimulator, TPA, which accelerates skin papilloma formation.
FAQs
Researchers choose among genetic engineering, selective breeding, and controlled disease induction according to the human disease feature, biological process, or treatment response they need to reproduce. The selected approach determines how closely the model represents the intended experimental condition. Careful model selection therefore connects the research question to the phenotype and treatment response measured later.
Controlled genetics and environment reduce unwanted variation between experimental animals, helping researchers obtain more reproducible results. These controls make it easier to compare phenotypes, biomarkers, and treatment responses between groups. Appropriate control groups remain essential because they provide the reference needed to determine whether an observed change is associated with the modeled disease or the intervention.
Mouse and human biology are not identical, so a result observed in mice may not predict the same disease behavior or treatment response in people. Researchers must interpret findings cautiously and validate them in additional model systems. This limitation is especially important when using mouse data to support decisions about potential therapies or human studies.
A typical evaluation establishes the selected model, includes appropriate comparison controls, and measures relevant phenotypes, biomarkers, and responses after treatment. Researchers then compare the findings across groups to assess whether the intervention changes disease-related features or produces unwanted effects. This workflow links the model's biological behavior with evidence about efficacy and toxicity.
In medicine, these models allow researchers to examine whether a potential drug produces a desired response while also monitoring harmful effects under controlled conditions. Comparing treated animals with appropriate controls helps distinguish treatment-associated changes from baseline model features. The resulting evidence can inform whether a therapy merits further evaluation before studies in humans.
The models support investigations of disease mechanisms, measurable biomarkers, treatment responses, drug efficacy, and toxicity. Their controlled experimental setting allows several aspects of a disease or intervention to be examined within one research framework. However, findings should be integrated with evidence from additional model systems because mouse results alone may not capture human biology completely.
