Does cold atmospheric plasma help with wound healing and immune signaling?
Cold atmospheric plasma (CAP) is a technology that uses a mixture of reactive oxygen and nitrogen species (RONS), charged particles, and electric fields to interact with biological tissues. Research suggests that CAP can act as a tool to regulate immune responses and promote the healing of skin wounds.
What the research says
CAP is considered a promising tool for wound healing and tissue regeneration because it can modulate the immune microenvironment and reduce inflammation 7. It works by influencing specific signaling pathways, such as NF-κB, Nrf2-Keap1, and MAPK, which are involved in how cells respond to external signals 1.
Studies show that CAP can promote tissue proliferation and has been shown to be effective in treating various inflammatory skin conditions 8. Specifically, when delivered through a controlled-release system, CAP can encourage macrophages—cells that play a key role in the immune system—to shift toward a state that supports healing (M2 polarization) while increasing the secretion of growth factors that help cells multiply and move to repair tissue 7. Additionally, CAP has been identified as a redox regulatory tool that can stimulate antioxidant responses in skin conditions 6.
What to ask your doctor
- Can cold atmospheric plasma (CAP) be used as a treatment for my specific type of wound?
- How does CAP affect the immune response and inflammation in skin tissue?
- Are there specific delivery methods, such as scaffolds, that help control the dosage of plasma to prevent tissue damage?
- What are the current clinical applications of CAP for skin regeneration and inflammatory skin diseases?
