説明:
Calcitonin-related polypeptide alpha (CALCA) is a protein-encoded gene, also known as CALC1, CGRP, or CGRP-α. Multiple genetic factors and epigenetic modifications regulate CALCA gene expression, and it forms peptide hormones calcitonin (CT), α-isoform of calcitonin gene-related peptide (CGRP), and katacalcin through tissue-specific RNA alternative splicing and non-active precursor protein cleavage in transcription and translation. Calcitonin is synthesized and secreted by thyroid parafollicular cells, mainly involved in regulating calcium levels and phosphorus metabolism in bones and kidneys. It can reduce the concentration of calcium and phosphorus in the plasma and inhibit the absorption of calcium and phosphorus. CGRP mainly acts as a vasodilator and antimicrobial peptide, which can cause dilatation of coronary arteries, cerebral vessels, and systemic vessels, and help to regulate blood pressure. CGRP is also widely distributed in the pain pathways of the peripheral and central nervous system (CNS) of the human body, and its receptors are also expressed in the pain pathways. CGRP participates in the transmission of pain signals from the periphery to the CNS and plays a key role in pain regulation, which is related to the pathogenesis of a variety of pain diseases and related syndromes, including somatic pain, visceral pain, neuropathic pain, inflammatory pain, and migraine. Katacalcin mainly exists as a peptide that can effectively lower plasma calcium, and its effect of lowering serum calcium levels is almost the same as that of calcitonin. CALCA gene polymorphism is associated with a variety of diseases, including reflex sympathetic dystrophy syndrome, complex regional pain syndrome, ischemic stroke, Parkinson's disease, ovarian cancer, bone mineral density, migraine, schizophrenia, bipolar disorder, and primary hypertension [1-5]. CALCA is a potential target for new therapies for a variety of diseases. Currently, various CALCA antagonists are being developed for the treatment of migraine and primary hypertension, and research on targeting CALCA for diseases such as Alzheimer's disease and Parkinson's disease is also ongoing [6-7].
This strain is a humanized mouse model of the Calca gene. Using gene editing technology, the base sequence of the mouse Calca gene from the start codon to the 3’UTR region was replaced by the corresponding sequence in the human CALCA gene, while the 5’UTR region of the mouse Calca gene was retained. Homozygous B6-hCALCA mice are viable and fertile and can be used to study the mechanisms of various physiological and pathological processes such as blood pressure regulation, cell proliferation, cell apoptosis, vascular biology, physiological bone marrow production, inflammation, tumor growth, and research on CALCA-targeted migraine drugs and therapies.

B6-hIL23A/hIL12B/hTL1A

説明:
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].
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 [6]. 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 [7]. 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) [6]. 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 [8-10].
