Raynaud's Syndrome
Raynaud's syndrome is a complex condition characterized by vasospastic attacks and impaired blood flow. Our company, as a leader in the field of autoimmune disease research, is dedicated to advancing the therapy development of RS and helping to improve the R&D efficiency of global pharmaceutical companies.
Overview of Raynaud's Syndrome
Raynaud's syndrome (RS), also known as Raynaud's phenomenon, is a disorder characterized by vasospastic attacks primarily affecting the fingers and toes, triggered by exposure to cold temperatures or emotional stress. These episodes lead to a temporary reduction in blood flow to the affected areas, resulting in color changes (pallor, cyanosis), numbness, and pain. RS can occur in two forms: primary (idiopathic) and secondary to an underlying condition such as connective tissue diseases, autoimmune disorders, or vascular diseases.
- Pathogenesis of Raynaud's Syndrome
The pathogenesis of Raynaud's syndrome involves a complex interplay between vascular dysfunction, sympathetic nerve hyperactivity, and abnormalities in the microcirculation. Endothelial dysfunction, characterized by impaired production of nitric oxide and increased vasoconstrictor mediators, plays a significant role in the initiation and perpetuation of vasospastic episodes. Additionally, abnormalities in the autonomic nervous system, particularly sympathetic overactivity, contribute to excessive vasoconstriction.

Drug Discovery and Development for Raynaud's Syndrome
Calcium-channel blockers, such as nifedipine, amlodipine, and nicardipine, are considered first-line therapy for Raynaud's syndrome. These medications act by blocking calcium influx into vascular smooth muscle cells, leading to vasodilation and improved blood flow. There are also some other targeted drugs and therapies such as alpha 1-adrenergic blockers, renin-angiotensin system modulators, serotonin reuptake inhibitors, and phosphodiesterase inhibitors, which are also used in the therapeutics strategy of Raynaud's syndrome.

Our Services
With our comprehensive therapeutic development platform, we offer a wide range of diagnostics and therapy development services specifically for Raynaud's syndrome. In addition, our dedicated team of experts has extensive experience and can provide you with customized solutions. Our preclinical research services encompass a wide range of methodologies, including in vitro studies, animal studies, and mechanistic investigations, to support the development of RS therapeutics.
Induced Disease Models
Through meticulous induction protocols and rigorous characterization, we create reliable models that enable the study of various aspects of Raynaud's Syndrome.
One approach involves the induction of thermoregulatory tissue ischemia in murine models using anti-RNP antibodies.
Genetic Engineering Models
Our company excels in developing genetically modified animal models that harbor specific gene mutations associated with the disease, such as K10 knockout mice.
By manipulating the genome of these animals, we can investigate the functional consequences of these mutations and their impact on disease progression.
Our company provides cutting-edge cell-based in vitro model development services, utilizing primary cells, immortalized cell lines, or patient-derived cells to recreate the disease phenotype.
In Raynaud's syndrome, vascularized organoids derived from endothelial and smooth-muscle cells can be provided to mimic the microvascular dysfunction seen in this condition.
By utilizing our expertise in Raynaud's syndrome (RS) model development, we contribute to the advancement of RS research and the discovery of effective therapies. In addition to the aforementioned services and models, we also provide customized solutions and develop disease models that cater specifically to your unique needs. If our services have piqued your interest, please do not hesitate to contact us.
