The science

IFN-α: a key regulator of immune balance

Interferon-α is central to antiviral immunity. Yet chronic or dysregulated signaling may contribute to persistent activation and immune dysfunction.

01

Chronic viral infection

Persistent antigenic pressure may sustain immune activation.

02

IFN-α modulation

An investigational intervention point designed to address dysregulated signaling.

03

Immune balance

The intended biological direction is a more functional immune equilibrium.
