What are the potential mechanisms behind the beneficial effects of plasma treatment on wound healing and tissue regeneration? How can we optimize ...?

Plasma treatment, also known as plasma medicine or cold atmospheric plasma (CAP) treatment, is an emerging field in medicine that shows promise for various applications, including wound healing and tissue regeneration. Plasma is the fourth state of matter, consisting of ionized gas with high-energy electrons and various reactive species.

The beneficial effects of plasma treatment on wound healing and tissue regeneration are thought to arise from several mechanisms:

Antimicrobial effects: Plasma can generate reactive oxygen and nitrogen species, such as hydrogen peroxide, ozone, and nitric oxide, which possess antimicrobial properties. These species can effectively kill bacteria, fungi, and viruses present in the wound, reducing the risk of infection and promoting healing.

Stimulation of cell proliferation and migration: Plasma treatment has been shown to stimulate the proliferation and migration of various cell types involved in wound healing, including fibroblasts, keratinocytes, and endothelial cells. This enhanced cellular activity can accelerate the formation of granulation tissue and re-epithelialization, leading to faster wound closure.

Modulation of inflammatory response: Plasma treatment has been observed to modulate the inflammatory response in wounds. It can suppress excessive inflammation while promoting a controlled and balanced immune response, which is crucial for proper wound healing. This modulation can help reduce chronic inflammation and prevent excessive scar formation.

Induction of angiogenesis: Plasma treatment has the potential to induce angiogenesis, the formation of new blood vessels. This is essential for supplying oxygen and nutrients to healing tissues. The reactive species generated by plasma can stimulate the release of pro-angiogenic factors and promote endothelial cell proliferation and migration, facilitating the growth of new blood vessels.

To optimize plasma treatment for wound healing and tissue regeneration, several factors can be considered:

Plasma device parameters: The choice of plasma device and the parameters used, such as gas composition, treatment time, power, and frequency, can influence the effects on wound healing. Optimizing these parameters through research and experimentation can help determine the most effective conditions for promoting tissue regeneration.

Patient-specific considerations: Each patient's wound characteristics and medical history may influence the optimal approach to plasma treatment. Factors such as wound size, location, depth, and the presence of underlying conditions should be taken into account to tailor the treatment accordingly.

Combination therapies: Plasma treatment can be used in combination with other wound healing modalities, such as growth factors, dressings, or scaffolds, to enhance the overall regenerative effects. Synergistic interactions between plasma and these adjunctive therapies may lead to improved outcomes.

Safety and standardization: It's important to ensure the safety of plasma treatment by thoroughly evaluating its potential side effects and risks. Standardization of treatment protocols and guidelines can help establish best practices and promote consistent and reproducible results.

I guess partial decay of lymphocytes in blood sample (in vitro) makes plasma more effective. Cortisone or radiation are useful tools to provoke a decay. Thanks for question. See attachment, please.
