Nanoparticles designed to remove excess immune molecules from blood
Overactive immune system? Nanoparticles selectively capture harmful proteins and genetic fragments.
Deep Dive
Nanoparticles could remove harmful immune molecules from blood. When the immune system becomes too active, it can produce too many immune mediators—fragments of genetic material or proteins that regulate immune responses.
Key Points
- Nanoparticles are coated with receptors that bind specifically to excess immune mediators like cytokines and autoantibodies.
- The approach selectively removes harmful molecules without suppressing the entire immune system, reducing infection risk.
- Integration with dialysis-like filtration could allow continuous, real-time treatment of immune overreactions such as cytokine storms.
Why It Matters
Offers a precise way to treat autoimmune diseases and sepsis without broadly suppressing immunity.
