Mozart Therapeutics Showcases Revolutionary Preclinical Outcomes at Immunology 2025™

Mozart Therapeutics, a pioneer in immune modulation therapies, recently presented groundbreaking research at the annual meeting of the American Association of Immunologists (Immunology 2025™) held in Honolulu, Hawaii, from May 3-7. The company revealed pivotal advancements related to the functionality of CD8 regulatory T cells (Tregs) and their potential in treating autoimmune diseases, particularly Type 1 diabetes (T1D).

Key Discoveries Presented

Two significant presentations were unveiled:

1. Understanding CD8 Treg Functionality: The first presentation shed light on the role of CD8 Tregs as a distinct subset of cytolytic T cells. They selectively target self-reactive pathogenic T cells, potentially offering a pathway to prevent the destruction of pancreatic beta (β) cells in T1D. The preclinical data suggests that restoring the functionalities of CD8 Tregs in pancreatic organoid models could halt the detrimental T cell-mediated damage, making a strong case for therapeutic modulation in the context of T1D and other autoimmune disorders.

2. Targeting IL-15 for Expansion of CD8 Tregs: The second focus was on a targeted IL-15 mutein that facilitates the selective activation and expansion of these beneficial Tregs. This approach showed promising outcomes in improving survival rates in xenograft models of acute graft-versus-host disease and exhibited protective effects against tissue damage induced by autoantigens. The findings indicate significant potential for this method in patients suffering from autoimmune conditions characterized by low populations of CD8 Tregs.

Insights from Company Leadership

Courtney Crane, Senior Vice President of Translational Medicine at Mozart, expressed excitement about sharing these innovative findings with the scientific community. She emphasized the importance of understanding CD8 Treg functionalities for the rational design of novel therapeutic molecules. These advancements could significantly enhance therapeutic options for patients afflicted by autoimmune diseases, offering a pathway toward enduring disease management and improvement in quality of life.

Research Details

The presentations included the following abstracts:

• - Abstract 4194: "Despite Expression of Exhaustion Markers, CD8 Treg Are a Cytolytic Population that Targets Pathogenic CD4 Cells to Prevent Beta Cell Destruction by Type 1 Diabetes Peripheral Blood Mononuclear Cells."
• - Abstract 4856: "Targeting IL-15 to CD8 Treg Results in Their Selective Expansion and Activation, Presenting a Potential Therapeutic Approach to Ameliorate Autoimmune Diseases in Patients with Deficient CD8 Treg Populations."

Future Directions and Company Overview

Mozart Therapeutics remains at the forefront of developing first-in-class disease-modifying therapies aimed at managing autoimmune and inflammatory diseases efficiently. By reprioritizing therapeutic strategies that restore immune system balance through the CD8 Treg network, the company is positioning itself to change the landscape of treatment options available for patients with debilitating autoimmune conditions.
