Detailed Description

Mice that are homozygous for the targeted mutation are viable, fertile and normal in size. No endogenous gene product (mRNA or protein) is detected in spleen or mesenteric lymph node. EGFP is not expressed. Severe, but incompletely penetrant, defects of the inguinal, iliac, axillary, brachial, popliteal, deep cervical, renal, sacral, and parathymic lymph nodes are observed. The lymphoid patch of the cecum is absent and Peyer's patches are severely reduced and typically malformed. This mutant has defective B cell organization, an absence of primary follicle follicular dendritic cells, and reduced B cell LTa1b2 expression in spleen and lymph nodes. This mutant may be useful in B cell, follicular dendritic cell, and/or lymph node development studies.

Development

A targeting vector was constructed in which base pairs 18-116 of exon 2 from the endogenous gene were replaced with an in-frame stop codon, a Mengo virus internal ribosome entry site, an enhanced green fluorescent protein gene (EGFP), and a loxP-flanked neomycin resistance gene. The construct was electroporated into 129X1/SvJ derived JM-1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6J blastocysts and the resulting chimeric males were backcrossed for germ-line transmission to C57BL/6J females. Offspring were mated with Cre-expressing C57BL/6J to remove the neomycin resistance gene. The neo-excised heterozygotes were backcrossed to C57BL/6J for ten generations before being made homozygous.

Cxcl13^tm1Cys

Allele Symbol: Cxcl13^tm1Cys

Allele Name	targeted mutation 1, Jason G Cyster
Allele Type	Targeted (Reporter, Null/Knockout)
Allele Synonym(s)	BLC^-; CXCL13^-
Gene Symbol and Name	Cxcl13, chemokine (C-X-C motif) ligand 13
Gene Synonym(s)
Strain of Origin	129X1/SvJ
Chromosome	5
Molecular Note	Base pairs 18 through 116 (exon 2) were replaced by a cassette containing a stop codon followed by an internal ribosome entry site, an enhanced green fluorescent protein gene, and a floxed neo gene. The deleted region encoded amino acids 27 through 60, including 3 of the 4 conserved Cys residues. The absence of transcript and protein in homozygous mutant mice was confirmed by Northern and Western blot analyses of homozygous mutant mice.

Mammalian Phenotype Terms by Genotype

The following phenotype information is associated with a similar, but not exact match to this JAX^® Mice strain

Genotype: Cxcl13^tm1Cys/Cxcl13^tm1Cys
involves: 129X1/SvJ * C57BL/6

immune system phenotype

abnormal spleen B cell follicle morphology
- boundary between B-cell rich areas and T zones are often poorly demarcated, with increased numbers of B cells and T cells in reciprocal areas
- B cells fail to organize into polarized follicular clusters and appear as a ring of cells at the perimeter of T-cell areas

abnormal spleen marginal zone morphology
- spleen shows a thickened ring of IgM^hiIgD^lo marginal zone B cells and the boundary between the B cells in this area and the inner ring of B cells is disrupted, with increased numbers of IgM^hiIgD^lo cells in the outer marginal zone
- outer marginal zone

absent axillary lymph nodes
- in most mice

absent follicular dendritic cells
- absence of primary follicular dendritic cells in spleen and lymph nodes

decreased spleen germinal center size
- germinal centers form in spleen after immunization with T-cell dependent antigen, however they are misplaced and smaller

decreased lymph node number
- most mice lack inguinal, iliac, sacral, brachial, and axillary lymph nodes
- Normal - however, a full set of mesenteric lymph nodes is observed
- a full set of mesenteric lymph nodes were observed

Breeding Considerations

When maintaining a live colony, these mice are maintained as homozygotes. Despite defective B cell function and lymph node development, the mutants live and breed normally in SPF vivaria.

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.

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. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
