B6-hIL31RA
Product ID:
C001917
Strain:
C57BL/6NCya
Status:
Description:
The IL31RA gene encodes the interleukin-31 receptor subunit alpha, a type I cytokine receptor that serves as a critical mediator in neuroimmune communication. The protein typically functions as a heterodimer by associating with the oncostatin M receptor (OSMRβ) to form the functional IL-31 receptor complex, which triggers intracellular signaling through the JAK/STAT (primarily STAT3), PI3K/AKT, and MAPK pathways [1]. While the gene is expressed at low levels across various tissues, including the testis, thymus, and bone marrow, it is highly localized and functionally significant in CD14+ monocytes, macrophages, keratinocytes, and a specific subset of dorsal root ganglia (DRG) neurons. In these tissues, IL31RA plays a pivotal role in mediating pruritus (itching) and regulating skin immunity and inflammation [2]. Genetically, dysregulation of the IL31RA pathway is heavily implicated in the pathogenesis of inflammatory and pruritic diseases such as atopic dermatitis, prurigo nodularis, allergic asthma, and certain cutaneous T-cell lymphomas, making it a major therapeutic target for monoclonal antibodies like nemolizumab [3].
The B6-hIL31RA mouse is a humanized model constructed through gene-editing technology, in which the sequences from aa.19 to partial intron 4 of mouse Il31ra were deleted, and the human IL31RA extracellular domain-mouse Il31ra transmembrane-cytoplasmic domain-3’UTR of mouse Il31ra WPRE-BGH pA cassette was inserted downstream of mouse Il31ra signal peptide. This model can be used for research on inflammatory and pruritic diseases such as atopic dermatitis, prurigo nodularis, allergic asthma, and certain cutaneous T-cell lymphomas, as well as for screening, development, and preclinical evaluation of IL31RA-targeted therapeutics.

B6-hTL1A/hIL23A
Product ID:
C001837
Strain:
C57BL/6N;6JCya
Status:
Description:
TNF-like ligand 1A (TL1A), also known as TNF superfamily member 15 (TNFSF15), is a member of the tumor necrosis factor (TNF) family encoded by the TNFSF15 gene in humans. TL1A acts as a ligand for death receptor 3 (DR3) and decoy receptor 3 (DcR3), providing a stimulatory signal for downstream pathways. It regulates the proliferation, activation, and apoptosis of effector cells, as well as cytokine and chemokine production. TL1A is expressed in various immune cells, including monocytes, macrophages, dendritic cells, and T cells, as well as in non-immune cells such as synovial fibroblasts and endothelial cells. It plays a crucial role in modulating immune responses by promoting the differentiation and survival of T cells, particularly Th17 cells involved in inflammatory processes [1]. TL1A enhances IL-2 responses in anti-CD3/CD28-stimulated T cells and synergizes with IL-12 and IL-18 to augment IFN-γ release in human T and NK cells, biasing T cell differentiation toward a Th1 phenotype [2]. Dysregulation of TL1A expression is implicated in autoimmune diseases, including inflammatory bowel disease (IBD), rheumatoid arthritis (RA), primary biliary cholangitis (PBC), systemic lupus erythematosus (SLE), and ankylosing spondylitis (AS) [1]. TL1A has emerged as a promising therapeutic target, with ongoing research focused on developing monoclonal antibodies and other biologics to neutralize TL1A and reduce inflammation in autoimmune disorders. Clinical trial results suggest that TL1A inhibition can be used in the treatment of various autoimmune diseases, particularly IBD [3-5].
The IL23A gene encodes the p19 subunit, a component of interleukin-23 (IL-23), which forms a heterodimer with the p40 subunit (encoded by IL12B) to generate the functional IL-23 cytokine [1]. Primarily expressed by activated dendritic cells, macrophages, and monocytes, IL-23 signals through the IL-23 receptor (IL-23R) complex, activating the JAK-STAT pathway to promote Th17 cell differentiation and maintain IL-17 production. This process drives inflammatory responses and mucosal immunity against extracellular pathogens [6-7]. Genetic polymorphisms within IL23A are strongly associated with autoimmune and inflammatory diseases, including psoriasis, Crohn's disease, and inflammatory bowel disease, due to dysregulated Th17 activity and chronic inflammation [6-7]. Monoclonal antibodies targeting IL-23, such as risankizumab and guselkumab, selectively block the p19 subunit, demonstrating therapeutic efficacy in psoriasis and inflammatory bowel diseases by suppressing pathogenic IL-17/Th17 pathways [8]. While IL-23 plays a role in protective immunity, its overactivation contributes to tissue damage in autoimmune settings, highlighting its dual function in immune regulation and disease pathogenesis [6-9].
B6-hTL1A/hIL23A mice are humanized models generated by crossing B6-hTL1A (TNFSF15) mice (Catalog No.: C001603) with B6-hIL23A mice (Catalog No.: C001618). These mice are suitable for studying the pathological mechanisms and therapeutic strategies of allergic and inflammatory diseases, immune-related disorders, and cancer, as well as for the screening, development, and preclinical evaluation of TL1A/IL23A-targeted drugs.

B6-hCLEC4C
Product ID:
C001726
Strain:
C57BL/6NCya
Status:
Description:
The CLEC4C gene, also known as BDCA-2 or CD303, encodes a type II transmembrane C-type lectin receptor predominantly expressed by plasmacytoid dendritic cells (pDCs) [1]. This receptor plays a critical role in pDC biology and serves as a key marker for this cell type [2]. The CLEC4C protein, featuring a carbohydrate recognition domain, is implicated in the capture and subsequent processing of antigens, potentially through the recognition of specific glycans and immunoglobulin G [1]. Functionally, CLEC4C acts as a signaling receptor within pDCs, and its engagement can negatively regulate the production of type I interferons, thereby modulating immune responses [2]. Notably, dysregulation of CLEC4C expression and pDC function has been associated with the pathogenesis of autoimmune disorders, including systemic lupus erythematosus (SLE), as well as in the context of certain hematological malignancies [3]. Litifilimab is a monoclonal antibody that targets CLEC4C and is under investigation for the treatment of SLE and other interferonopathies [4]. CLEC4C is a human gene, while Clec4b1 is its orthologous gene in mice.
The B6-hCLEC4C mouse is a humanized model constructed by replacing the mouse Clec4b1 endogenous extracellular domain with the human CLEC4C extracellular domain. This model can be used to study the pathological mechanisms and therapeutic methods of autoimmune disorders and hematological malignancies, as well as the screening and development of CLEC4C-targeted drugs, and preclinical efficacy and safety evaluations.

B6-hBCMA (hTNFRSF17)
Product ID:
C001630
Strain:
C57BL/6NCya
Status:
Description:
The TNFRSF17 gene, also known as BCMA, encodes a protein belonging to the tumor necrosis factor receptor superfamily. This protein is predominantly expressed in mature B lymphocytes, particularly plasma cells, with lower expression in early B cells and non-B cells [1-2]. As a type III transmembrane glycoprotein, TNFRSF17 plays a critical role in B cell survival and differentiation, acting as a key regulator of B cell maturation [2]. Functionally, TNFRSF17 primarily acts as a receptor for the B cell-activating factor (BAFF). Upon BAFF binding, it activates both the classical NF-κB pathway and the non-classical MAPK8/JNK pathway, subsequently regulating downstream gene expression to promote B cell survival, proliferation, and antibody secretion. Furthermore, TNFRSF17 can interact with TNFR-associated factors (TRAFs) 1, 2, and 3, further mediating physiological processes related to cell differentiation and growth [1-2]. Multiple studies have demonstrated that the TNFRSF17 gene and its protein are associated with various B cell-related diseases. Notably, this gene exhibits abnormally high expression in diseases such as multiple myeloma and systemic lupus erythematosus, rendering it a potential therapeutic target for these conditions [3-4].
The B6-hBCMA (TNFRSF17) mouse is a humanized model constructed using gene editing technology, where the mouse BCMA endogenous extracellular domain was replaced with the human BCMA extracellular domain. Homozygous B6-hBCMA (TNFRSF17) mice are viable and fertile. This model can be used for studying the pathological mechanisms and therapeutic approaches of multiple myeloma, systemic lupus erythematosus, and various B cell-related diseases and for the development of BCMA-targeted drugs.

B6-hIL4RA
Product ID:
C001629
Strain:
C57BL/6NCya
Status:
Description:
Interleukin-4 (IL-4) and its receptor, IL-4R, are pivotal regulators of immune responses and inflammation. The IL4 gene encodes the IL-4 cytokine, a multifunctional protein predominantly secreted by Th2 cells, mast cells, and eosinophils, while the IL4R gene encodes the IL-4 receptor, which is expressed on a variety of immune cells, including B cells, T cells, macrophages, and endothelial cells. IL-4 binds to IL-4R, which exists in two distinct forms: Type I (comprising IL-4Rα and the common γ-chain) and Type II (comprising IL-4Rα and IL-13Rα1) [1]. This interaction activates the JAK-STAT signaling pathway, driving Th2 cell differentiation, B cell class switching to IgE, and anti-inflammatory responses. The IL-4/IL-4R signaling axis is critically implicated in allergic diseases such as asthma, atopic dermatitis, and allergic rhinitis, as well as in parasitic infections and certain cancers [2-5]. Dysregulation of this pathway underlies various pathological conditions, positioning IL-4R as a promising therapeutic target. For instance, dupilumab, a monoclonal antibody targeting IL-4Rα, has been approved for the treatment of atopic dermatitis, asthma, and chronic rhinosinusitis with nasal polyps, underscoring the therapeutic potential of modulating this pathway [6-7].
B6-hIL4RA mice are humanized models generated using gene editing technology by replacing the extracellular domain of the mouse Il4ra with the corresponding human IL4R extracellular domain, while retaining the murine signal peptide. Homozygous B6-hIL4RA mice are viable and fertile. This model is an invaluable tool for studying allergic diseases (e.g., asthma and atopic dermatitis), Th2 immune responses, parasitic infections, tumor immunology, and chronic inflammation. Furthermore, it is a robust preclinical platform for evaluating the efficacy and mechanisms of therapeutic agents targeting the IL-4Rα.

B6-hSCN9A
Product ID:
I001216
Strain:
C57BL/6NCya
Status:
Description:
The SCN9A gene encodes the Nav1.7 sodium channel protein, which is primarily expressed in the sensory and sympathetic nerves of the peripheral nervous system and is highly expressed in the dorsal root ganglia. Nav1.7 sodium channels play a crucial role in transmitting positively charged sodium ions within cells, which are essential for generating and transmitting electrical signals. When a person experiences pain, this protein releases sodium ion currents that amplify and stimulate nerve cells, sending electrical signals to the brain, thereby causing the sensation of pain. The SCN9A gene guides the entry of sodium ions into cells and facilitates communication between neurons. Mutations in the SCN9A gene can alter the function of sodium channels in the brain, disrupting neuronal communication and leading to various pain, olfactory, and neurological disorders such as erythromelalgia, paroxysmal extreme pain disorder, Dravet syndrome, small fiber neuropathy, and congenital insensitivity to pain. The abnormal protein function and symptoms resulting from gene mutations are directly related to the severity of the mutations, and different mutation types may lead to completely different conditions.
SCN9A is an excellent target for analgesic drug development. Downregulation of SCN9A expression can alleviate acute pain as well as certain types of inflammatory and neuropathic pain [1]. OliPass Corporation, a South Korean biotechnology company, has developed an antisense peptide nucleic acid (PNA) analgesic targeting SCN9A (OLP-1002), which has entered Phase 2a clinical trials. Antisense PNA is an artificially synthesized DNA/RNA mimic that inhibits RNA/DNA transcription and translation by complementary pairing with RNA/DNA sequences. The drug has shown strong analgesic effects and prolonged therapeutic duration in Australian patients with moderate to severe chronic osteoarthritis pain. It is estimated that due to its potent efficacy, excellent safety profile, and broad therapeutic scope, OLP-1002 could generate over $50 billion in market potential annually [2-4].
The B6-hSCN9A mouse is a mouse Scn9a humanized model, generated by replacing the mouse Scn9a gene (including the 5' UTR and 3' UTR) with the corresponding human SCN9A gene sequence using gene editing technology. Internal research revealed that during the generation of B6-hSCN9A mice, the murine Scn9a gene was inserted unexpectedly, and its precise genomic insertion site remains undetermined*. This strain is suitable for studying the pathogenic mechanisms of neurological diseases such as erythromelalgia, Dravet syndrome, small fiber neuropathy, and congenital insensitivity to pain, as well as for screening analgesic drug candidates. In addition, based on the independently developed TurboKnockout fusion BAC recombination technology, Cyagen can also provide customized services.

Description:
The IL23A gene encodes the p19 subunit, a component of interleukin-23 (IL-23), which forms a heterodimer with the p40 subunit (encoded by IL12B) to generate the functional IL-23 cytokine [1]. Primarily expressed by activated dendritic cells, macrophages, and monocytes, IL-23 signals through the IL-23 receptor (IL-23R) complex, activating the JAK-STAT pathway to promote Th17 cell differentiation and maintain IL-17 production. This process drives inflammatory responses and mucosal immunity against extracellular pathogens [1-2]. . Genetic polymorphisms within IL23A are strongly associated with autoimmune and inflammatory diseases, including psoriasis, Crohn's disease, and inflammatory bowel disease, due to dysregulated Th17 activity and chronic inflammation [1-2]. Monoclonal antibodies targeting IL-23, such as risankizumab and guselkumab, selectively block the p19 subunit, demonstrating therapeutic efficacy in psoriasis and inflammatory bowel diseases by suppressing pathogenic IL-17/Th17 pathways [3]. Also, monoclonal antibodies targeting IL-12B, such as ustekinumab, are clinically utilized for the treatment of moderate to severe psoriasis and Crohn's disease [4]. While IL-23 plays a role in protective immunity, its overactivation contributes to tissue damage in autoimmune settings, highlighting its dual function in immune regulation and disease pathogenesis [1-5].

C57BL/6NCya
Status:
Description:
The SLC16A1 gene encodes the Monocarboxylate Transporter 1 (MCT1) protein, a vital proton-coupled symporter that facilitates the rapid transmembrane movement of metabolic substrates, including lactate, pyruvate, and ketone bodies (acetoacetate and β-hydroxybutyrate). This gene is ubiquitously expressed across nearly all human tissues to maintain energy balance and pH homeostasis, with notably high levels labeled in the heart, oxidative skeletal muscle fibers, erythrocytes (red blood cells), and the brain (specifically in oligodendrocytes and the blood-brain barrier), while being uniquely "disallowed" or suppressed in normal pancreatic beta-cells to prevent inappropriate insulin release [1]. Functionally, MCT1 is central to the "lactate shuttle" mechanism, allowing tissues to coordinate metabolic fuel exchange by facilitating either the influx or efflux of substrates depending on the concentration gradient and proton motive force [2]. Mutations in SLC16A1 are clinically linked to Erythrocyte Lactate Transporter Defect, which causes exercise-induced muscle cramping and fatigue, and Monocarboxylate Transporter 1 Deficiency, a rare disorder characterized by recurrent episodes of severe ketoacidosis and vomiting triggered by fasting or infection [3]. Conversely, gain-of-function mutations in the gene's promoter lead to familial hyperinsulinemia type 7 (HHF7), where exercise triggers excessive insulin secretion, while its widespread overexpression in various cancers (such as melanoma and lung cancer) supports the Warburg effect by managing lactate efflux to prevent intracellular acidification and fueling tumor progression [4].
The B6-huSLC16A1 mouse is a humanized model constructed through gene-editing technology, in which the sequences from the ATG start codon to the TGA stop codon of the endogenous mouse Slc16a1 gene are replaced with the sequences from the ATG start codon to the TGA stop codon of the human SLC16A1 gene. This model can be used for research on diseases such as Erythrocyte Lactate Transporter Defect, Monocarboxylate Transporter 1 Deficiency, familial hyperinsulinemia type 7 (HHF7), and various cancers, as well as for screening, development, and preclinical evaluation of SLC16A1-targeted therapeutics.
