Type JAX® GEMM® Strain - Mutant Strain Type JAX® GEMM® Strain - Transgenic Mating System Inbred x Hemizygote (Female x Male) Species laboratory mouse Donating Investigator Dan Littman, New York University Medical Center Generation N8+6F1N3 (08-JAN-08) Strain Description
Mice that are homozygous for the transgene are viable, normal in size and do not display any gross physical or behavioral abnormalities. Upon diphtheria toxin (DT) administration, mice harboring this transgene are transiently depleted of dendritic cell (DC) populations. All CD8+ and CD8- DC in the spleen express EGFP and are DT sensitive. Immunohistochemical and flow cytometric analysis reveals EGFP expression and DT-inducible depletion of CD11chigh DC in spleen, lymph node, lung, liver and lamina propria tissues, as well as the defined macrophage subpopulations of the alveolar, lamina propria, metallophillic and marginal zone. Rapid reduction of CD11c+ DC populations induced by intraperitoneal injection of DT persists for approximately 2 days, after which the cell population gradually recovers. While transient DC depletion was not associated with sign of illness or long-term defects, repeated DT induction is lethal to the mouse. Long term depletion of this cell population can be achieved by the generation of mixed irradiation chimeras. This mutant mouse strain may be useful in studies of mononuclear phagocyte origins and the specific role of dendritic cells in the immune response.In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. It should be noted that the phenotype could vary from that originally described. We will modify the strain description if necessary as published results become available.
Strain Development
A transgene was designed to place a simian Diphtheria Toxin Receptor (DTR)-Enhanced Green Fluorescent Protein (EGFP, Stratagene) fusion protein under the control of the Itgax (or CD11c) promoter. This transgene was introduced into fertilized FVB/N donor eggs. The resulting chimeric animals were crossed to BALB/c mice, and then backcrossed to BALB/c for 8 generations. This transgene has been mapped to mouse Chromosome 1 (~52 cM; 87395187bp position) via single nucleotide polymorphism (SNP) analysis by The Jackson Laboratory.

| Strain of Origin | FVB/N | ||
| Site of Expression | Expression of the transgene is specific to splenic dendritic cells. All CD8+ and CD8- dentritic cells in the spleen fluoresce and are DT sensititve. | ||
| Expressed Gene | GFP, Green Fluorescent Protein, jellyfish | ||
| Green Fluorescent Protein (GFP), derived from the jellyfish Aequorea victoria, is a versatile reporter molecule which has found use in many biological applications. The original molecule has been modified in order to enhance its fluorescence intensity (EGFP, enhanced GFP). When utilized in a transgenic construct, tissue expressing sufficient amounts of GFP will fluoresce when exposed to a 488 nm light source. | |||
| Expressed Gene | DTR, Simian Diphtheria Toxin Receptor, | ||
| Promoter | Itgax, integrin alpha X, mouse, laboratory | ||
| Molecular Note | The transgene contains sequence encoding DTR/GFP under the control of the mouse Itgax promoter. Two lines were creacted (line 11 and line 57) with 1 to 2 copies and 20 copies of the transgene, respectively. All CD8+ and CD8- dendritic cells in the spleen fluoresce and are DT sensitive. Immunohistochemical and flow cytometric analyses show that expression of the transgene is specific to splenic dendritic cells. [J:93488] | ||
