What is TCR transgenic mice?

These P25 TCR-Tg transgenic mice contain CD4 + T cells expressing a T-cell antigen receptor that recognizes Mycobacterium tuberculosis antigen. These mice may be useful for studying the process of the adaptive immune response to M. tuberculosis infection in the lungs.

What are OT mice?

OT I Mouse Details These homozygous mice contain transgenic inserts for mouse Tcra-V2 and Tcrb-V5 genes. The transgenic T cell receptor was designed to recognize ovalbumin residues 257-264 in the context of H2Kb and used to study the role of peptides in positive selection and the response of CD8+ T cells to antigen.

How are TCR transgenic mice made?

The production of TCR Tg mice starts by generating genomic constructs for transformation. Genes encoding TCR α- or β-chains are extracted from T cell clones expressing antigen-specific TCRs. T cell clones are generated through several methods [10,11] that are followed by the selection of a specific T cell clone.

Do OT 1 mice have CD4 cells?

Most dramatically, ≈90% of Vα2+ T cells in OT-1+RAG+TAP−/− mice were CD4+ (Fig. 3B). The OT-1 TCRβ chain has been shown to pair with TCRα chains that differ only in the CDR3 region to generate both CD4+ and CD8+ T cells in mice (36, 37).

What is P14 mice?

Origin: The Transgenic LCMV-P14 T Cell Receptor transgenic mouse was made by Dr. Hanspeter Pircher and colleagues in 1989 at the Department of Experimental Pathology in Zurich, Switzerland. The transgenic line was created by coinjection of the P14 Tcrα and Tcrβ gene constructs into (C57BL/6 x DBA/2)F2 fertilized eggs.

What is a transgenic T cell?

TCR-transgenic T cells represent a specific and sensitive tool for antigen discovery through cDNA library screening. Importantly, the use of TCR-transgenic T cells facilitates screening procedures, as large amounts of antigen-specific T cells can be generated in several days.

What is OT II mice?

OT II Mouse Details These homozygous transgenic mice express the mouse alpha-chain and beta-chain T cell receptor that pairs with the CD4 coreceptor and is specific for chicken ovalbumin 323-339 in the context of I-A b. Homozygous mice are viable and fertile.

What is DO11 10?

The RRID Number allows for easier identification of JAX and MMRRC strains in research publications. Common Name: DO11.10. Mice carrying this MHC class II restricted rearranged T cell receptor transgene on a H2d background react to ovalbumin (OVA) peptide antigen.

What does the term transgenic refer to?

Transgenic refers to an organism or cell whose genome has been altered by the introduction of one or more foreign DNA sequences from another species by artificial means. Transgenic organisms are generated in the laboratory for research purposes.

What is Siinfekl peptide?

Ovalbumin peptide SIINFEKL (H-2 Kb) is a single peptide for stimulation of T cells. The peptide from Ovalbumin is synthesized as it is presented by the MHC class I H-2 Kb allele and can be used for targeted in vitro generation and expansion of antigen-specific CD8+ T cells.

What is Lcmv?

Lymphocytic Choriomeningitis Virus (LCMV) is a virus carried by rodents such as hamsters, guinea pigs or mice. LCMV rarely infects humans and most people with normal immune systems who are exposed to the virus do not become ill.

How does TCR therapy work?

T Cell Receptor Engineering (TCR) Like CAR T-cell therapy, engineered T cell receptor therapy involves treating cancer with activated T lymphocytes from the body. Both strategies attach new receptors to the cells’ surfaces, enabling them to attack different forms of cancer.

How does TCR T work?

TCR-T cells are genetically engineered TCR products that can recognize specific antigens. The core goal behind TCR-T cell technology is to directly modify TCR binding to tumor antigens. The affinity of human TCRs to these antigens is relatively low, which makes it impossible to recognize and kill tumors effectively.

What are DO11 10 cells?

The DO11. 10 T cell hybridoma is a popular model system used to study CD4+ T cell responses, originally elicited by vaccination of Balb/c mice (H-2d haplotype) with hen egg white ovalbumin (OVA).

What is OVA peptide?

Definition. OVA Peptide is a class I (Kb)-restricted peptide epitope of ovalbumin presented by the class I MHC (major histocompatibility complex) molecule, H-2Kb (class I genes of the mouse MHC).

What is the purpose of transgenic animals?

Transgenic animals provide a chance to produce animals that are a source of useful human therapeutic proteins like growth hormone, insulin, human lactoferrin, etc. Transgenic animals can be easily produced by transforming stem cells, growing in vitro, with the desired gene constructed by homologous recombination.

What are the examples of transgenic animals?

Examples of CRISPR-generated Transgenic Animals

• Salmon. The larger salmon in the background is a sister to the smaller one in the foreground.
• Chicken.
• Goats.
• Cows.
• Pigs.
• Mammoths.
• Humans.

What is ovalbumin peptide?

What is h2kb?

Abstract. The peptide-binding site of the murine MHC class I molecule H-2Kb contains a deep C pocket, that is critical for peptide binding, as it accepts the anchor phenylalanine or tyrosine residue located in the middle (position 5, P5F/Y) of H-2Kb binding peptides. H-2Kb predominantly binds octameric peptides.

What are the applications of transgenic cyt5cc7 mice?

Applications include studies of inflammation, tolerance, and T cell development. The Transgenic Cyt5CC7 T Cell Receptor mice were made by Dr. Barbara Fazekis de St. Groth and colleagues in 1992 at Stanford University using B10B6F1 donor embryos.

What are the applications of CD4+ T cell mice?

These mice are useful for in vitro studies of CD4+ T cell differentiation into TH1 and TH2 populations and as a source of donor cells for adoptive transfer into B10.A mice for in vivo studies of inflammation and tolerance. Applications include studies of inflammation, tolerance, and T cell development.

What is RAG2 knockout/transgenic cyt5cc7?

The Rag2 Knockout/Transgenic Cyt5CC7 T Cell Receptor line is homozygous for a transgene that encodes a T cell receptor that is specific for a pigeon cytochrome c peptide, amino acids 81-104, presented by the MHC class II molecule I-Ea/k.

Is there a model available for immediate cryorecovery of pigeon cytochrome c?

This model is available for immediate cryorecovery. The Rag2 Knockout/Transgenic Cyt5CC7 T Cell Receptor line is homozygous for a transgene that encodes a T cell receptor that is specific for a pigeon cytochrome c peptide, amino acids 81-104, presented by the MHC class II molecule I-Ea/k.
