Autoimmune Diseases

Autoimmune diseases pose a major challenge to health systems around the world, impacting the lives of millions. These chronic diseases usually cause the immune system of the body to inflict damage on the body. Additionally, autoimmune diseases cause chronic and acute inflammation and damage to the systems within the body. Protheragen is at the forefront of developing innovative therapies and compounds targeting MyD88 pathways to address the critical unmet needs in autoimmune disease research and development.
Introduction to Autoimmune Diseases
Autoimmune diseases are a distinct and the most difficult chronic diseases of the modern world. The body's immune system, which is in charge of offering defense and protection, instead chooses to battles with the body's healthier cells and tissues. The consequence of this reaction is severe damage to healthy tissues and inflammation of parts of the body. The body and environment play a role in determining the start and development of this disease.
MyD88 in Autoimmune Pathogenesis
In autoimmune diseases, the failure of the immune system to maintain tolerance results in chronic inflammation, activation of specific lymph nodes, and synthesis of autoantibodies. Myeloid Differentiation Primary Response 88 (MyD88) plays a role in the immune system's response and inflammation's MyD88. MyD88 is an adaptor protein that is essential for TLRs and IL-1R family receptors downstream signaling.

(Chen, Zou, et al., 2025)In the chronic stage of autoimmune diseases, it is believed that the MyD88-mediated TLR-IL-1R signaling is an essential factor in maintaining inflammation and tissue damage. For example, MyD88 signaling dysregulation will lead to excess production of TNF-α, IL-1β, and IL-6, which fuels inflammation in the arthritis and systemic lupus. MyD88 blocking is believed to provide a good opportunity to control autoimmune overdrive and inflammation damage to tissues.
Targeting MyD88 for the Therapeutic Development in Autoimmune Diseases
| Therapeutic Strategy | Drug | Indication | Key Progress | Development Stage |
| TIR dimerization inhibitor | c(MyD 4-4) | Multiple sclerosis (MS) | Improved neurological scores in EAE models; oral bioavailability optimization | Phase I |
| MyD88 allosteric modulator | TJ-M2010-5 | Rheumatoid arthritis (RA) | Reduced joint swelling in CIA models; localized hydrogel delivery | Preclinical |
| MyD88/BTK dual blockade | ST2825 + Ibrutinib | Systemic lupus erythematosus (SLE) | Suppressed TLR9-BCR crosstalk; decreased autoantibodies | Preclinical |
