[Hinews] Nexmoss, a South Korean biotech company specializing in DNA aptamers, highlighted new data on its patented compound Aptamin C at the International Union of Immunological Societies (IUIS) 2025 Congress in Vienna. The company presented findings on the compound’s immune-enhancing properties, positioning it as a potential next-generation antioxidant and immunomodulatory therapy.

The IUIS Congress, a triennial gathering of the global immunology community, drew approximately 6,000 attendees from 120 countries. At the event, Professor Jae Seung Kang of Seoul National University College of Medicine delivered a highly anticipated presentation titled “Effects of Aptamin C on NK Cell Activation and Cytotoxicity,” which attracted considerable interest from the scientific community.

Professor Kang presented research showing that Aptamin C overcomes the inherent instability of conventional vitamin C in the body and enhances natural killer (NK) cell activity and cytotoxicity. “Aptamin C shows remarkable promise in boosting NK cell function and antioxidant capabilities,” Kang stated, underscoring its potential as a breakthrough in immunotherapy.

Aptamin C combines DNA aptamer technology to inhibit vitamin C oxidation, improving its stability and antioxidant effects. The compound has drawn attention from experts in immuno-oncology and cell therapy as a potential candidate for next-generation antioxidant and immune-modulating treatments.
Jung-Wook Shim, CEO of Nexmoss, noted, “Following our European patent approval, this presentation at IUIS 2025 is an important opportunity to demonstrate Aptamin C’s potential and build a presence in international markets."

The announcement reflects Nexmoss’s efforts to strengthen its global presence and expand into overseas markets.
