Autistic Cre mice are genetically modified mice that express mutations or deletions of specific genes that have been associated with human autism. These mice are created by introducing a Cre recombinase gene under the control of a promoter specific to the gene of interest. The Cre recombinase then catalyzes the recombination of loxP sites, leading to the deletion or mutation of the targeted gene.
On the other hand, autism mouse models are created through a variety of methods, including genetic manipulation, exposure to environmental toxins, or maternal infection during pregnancy. These models aim to replicate some of the behavioral and neurobiological features of autism in humans, such as impaired social interaction and communication, repetitive behaviors, and altered brain development and function.
One of the main differences between the two is the level of specificity in targeting autism-related genes. Autistic Cre mice allow researchers to study the effects of specific gene mutations or deletions on behavior and brain function, whereas autism mouse models often involve a broader range of genetic or environmental factors that may contribute to the development of autism.
Additionally, autistic Cre mice are often used to study the cellular and molecular mechanisms underlying autism, such as changes in synaptic function or neurotransmitter signaling, whereas autism mouse models may focus more on behavioral and phenotypic characteristics of the disorder.
