Overview

Also Known As: Axl KO

These Axl KO mice may be useful in studies of innate immunity, autoimmunity, germ cell development and apoptosis. Axl is highly expressed by key cellular targets of ZIKA virus (ZIKV), and is proposed to promote viral entry in certain cell types (including non-Axl-expressing cells). Axl inhibition represents a potential approach for antiviral therapies.

Detailed Description

This targeted mutant was created and characterized by Deltagen, Inc. View phenotypic data developed by Deltagen.

Briefly, a bacterial beta-galactosidase gene (lacZ) was inserted into the Axl locus such that the endogenous gene promoter drives lacZ expression. RNA transcripts are detectable in all tissues analyzed. lacZ expression is detectable in all tissues or organs analyzed. There were no significant differences detected in the homozygous mutant mice when compared with age- and gender-matched wildtype control mice.

In combination with mutations in other receptor tyrosine kinases, this strain may be useful in studies of innate immunity, autoimmunity, germ cell development and apoptosis.

The TAM receptors (Tyro3, Axl, and Mertk) are a family of receptor tyrosine kinases whose ligands (Gas6 and Protein S) bind to phosphatidylserine on the surface of apoptotic cells and enveloped viruses. Axl is highly expressed by key cellular targets of ZIKA virus (ZIKV) - including human radial glial cells, astrocytes, endothelial cells and microglia in developing human cortex, and by progenitor cells in developing retina (Nowakowski et al. 2016 Cell Stem Cell 18:591), as well as in subtypes of trophoblasts (Tabata et al. 2016 Cell Host Microb. 20:155). Research in 2017 identifies a dual role of Axl during ZIKV infection of human glial cells (astrocytes and microglia) - promoting viral entry and modulating innate immune responses - and suggests Axl inhibition may represent a potential target for antiviral therapies (Meertens et al. 2017 Cell Rep. 18:324).

Development

This Axl KO allele has a Lac0-SA-IRES-lacZ-Neo555G/Kan cassette replacing exons 1-11 of the AXL receptor tyrosine kinase (Axl) gene. Upon arrival at The Jackson Laboratory, these mice had been backcrossed at least six generations to C57BL/6 mice.

Breeding Considerations

When maintaining a live colony, heterozygous mice may be bred together, to wildtype mice from the colony or to C57BL/6J inbred mice (Stock No. 000664). Alternatively, homozygous mice may be bred together.

We will fulfill your order by providing at least two carriers for each strain ordered. The total number, sex, and genotypes provided will vary, although typically 8 or more animals are provided. Please check genotypes which will be recovered. While the genotypes of all animals produced will be communicated to you prior to scheduling shipment, the genotypes of animals provided may not reflect the mating scheme and genotypes described in the strain description. Animals are typically ready to ship in 11-14 weeks. If a second recovery is required to produce the minimum number of animals, then delivery time would increase to approximately 25 weeks. If we fail to produce animals of the correct genotype, you will not be charged. We cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary.

Cryorecovery to establish a Dedicated Supply for greater quantities of mice. Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation.

Payment for services, products, shipping containers, and shipping costs that are rendered are expected within the payment terms indicated on the invoice or stated by contract. Invoices and account balances in arrears of stated terms may result in The Jackson Laboratory pursuing collection activities including but not limited to outside agencies and court filings.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
