Using Antibodies to Block IL-26 for Treating Inflammatory Diseases

A patent for specific antibodies that block the protein IL-26 to help treat inflammatory conditions like psoriasis and Crohn's disease.

What it covers

This patent describes a specific monoclonal antibody designed to bind to and neutralize a protein called Interleukin-26 (IL-26). IL-26 is a signaling molecule that can trigger inflammation in the body. By using these antibodies to block IL-26, the treatment aims to stop the inflammatory response, specifically by preventing IL-26 from causing damage independently of its usual receptor. The patent details the exact amino acid sequences (the building blocks of the antibody) required for this specific binding, ensuring the antibody targets IL-26 effectively. This could be used in patients to reduce symptoms of inflammatory diseases, such as skin thickening in psoriasis or the overproduction of other inflammatory markers like IL-6 and TNF.

What it doesn't cover

• —Does not cover any antibody that binds to IL-26 using different amino acid sequences than those specified in the claims.
• —Does not cover treatments that use small molecule drugs instead of monoclonal antibodies or their fragments.
• —Does not cover antibodies that bind to IL-26 but fail to inhibit its receptor-independent inflammatory function.
• —Does not cover general methods of treating inflammation that do not involve the specific IL-26 inhibition described.

The clever bit

The innovation lies in targeting the receptor-independent inflammatory function of IL-26, meaning the antibody stops the protein from causing trouble even if it is not using its standard cellular doorway to signal.

Why it matters

Inflammatory diseases like psoriasis and Crohn's are often treated with broad-spectrum immunosuppressants that can have significant side effects. By targeting a specific protein like IL-26, this approach offers a more precise way to calm the immune system. This patent provides the intellectual property foundation for developing a targeted therapy that could potentially offer better outcomes for patients with chronic autoimmune conditions.
