Autoimmune Addison's Disease
Autoimmune Addison's disease (AAD) is a rare and chronic autoimmune endocrine disorder characterized by the destruction of the adrenal cortex, leading to deficient production of cortisol and aldosterone. Our company, a leading player in the research and development of autoimmune disease and inflammatory drugs, is committed to providing professional AAD therapy development solutions.
Introduction to Autoimmune Addison's Disease
Autoimmune Addison's disease is a complex disorder that arises from the immune system mistakenly attacking the adrenal glands, leading to their destruction. The primary cause of AAD is the presence of autoantibodies targeting key enzymes involved in the synthesis of adrenal hormones, particularly 21-hydroxylase. This autoimmune response disrupts the normal functioning of the adrenal cortex, resulting in the diminished production of cortisol and aldosterone.
The pathogenesis of AAD involves a complex interplay between genetic predisposition and environmental triggers. Genetic susceptibility is conferred by specific HLA haplotypes, such as HLA-DR3 and HLA-DR4, which are commonly found in AAD cases. Environmental factors, including infections (such as viral and bacterial), contribute to the initiation and progression of the autoimmune response.

Drug Discovery and Development for Autoimmune Addison's Disease
Currently, the mainstay of therapeutics for AAD is lifelong hormone replacement therapy with glucocorticoids (such as hydrocortisone) and mineralocorticoids (such as fludrocortisone). These medications aim to replace the deficient cortisol and aldosterone, respectively, and help manage the symptoms and prevent adrenal crises.
In recent years, there has been growing interest in the development of targeted immunotherapies for AAD. These therapies focus on modulating the immune response to prevent further destruction of the adrenal cortex. Approaches under investigation include the use of biologics targeting specific immune cells or cytokines involved in the autoimmune process and the exploration of immune tolerance induction strategies.

Our Services
At our company, we are dedicated to advancing the field of AAD diagnostics. We offer comprehensive diagnostic panels that include the assessment of autoantibodies against key adrenal antigens, genetic testing for HLA haplotypes associated with AAD, and other relevant biomarkers. At the same time, our company has a dedicated research team that is developing and characterizing disease models of AAD to support the development of therapies.
Induced Animal Models
Induced animal models of AAD involve the experimental induction of adrenal autoimmunity through immunization or other means. Our company has expertise in developing induced animal models, wherein animals are immunized with adrenal cortex suspensions or specific adrenal autoantigens.
Our company specializes in developing co-culture models that mimic the autoimmune microenvironment observed in AAD. For example, immune cells, such as T cells and B cells, can be isolated from AAD cases or animal models and co-cultured with adrenal cell lines.
We utilize cutting-edge techniques to differentiate pluripotent stem cells or adult stem cells into adrenal organoids. These organoids consist of multiple cell types, including adrenocortical cells, immune cells, and endothelial cells, closely resembling the native adrenal tissue.
We conduct in vitro and in vivo studies to evaluate the safety, efficacy, and pharmacokinetic properties of potential therapeutics. 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.
