L-threonine involved in wound healing

L-Threonine plays a significant role in wound healing, with its key applications outlined as follows:

I. Promoting Collagen Synthesis  

Collagen is a crucial component in the formation of scar tissue during wound healing and is essential for the strength and elasticity of the wound. L-Threonine is one of the key building blocks required for collagen synthesis. It contributes to the amino acid sequence of collagen, providing the necessary material foundation for its production. When the body is deficient in L-Threonine, collagen synthesis is limited, which can slow down wound healing and lead to poor scar quality.  

During the proliferative phase of wound healing, fibroblasts synthesize collagen in large quantities. Adequate L-Threonine supply ensures that fibroblasts can efficiently synthesize and secrete collagen, accelerating the formation of granulation tissue at the wound site and promoting wound healing and repair.

II. Enhancing Immune Function  

A strong immune system is essential for fighting off pathogens and preventing infection, thus creating a favorable environment for wound healing. L-Threonine plays a critical role in maintaining normal immune system function. It promotes the proliferation and differentiation of immune cells, enhances the phagocytic capacity of macrophages, and strengthens the immune response of lymphocytes, thereby improving overall immunity.  

When the body receives enough L-Threonine, immune cells are better activated, leading to the production of more immune factors and antibodies. This helps eliminate bacteria and viruses around the wound, reducing the risk of infection and enabling the wound to heal in a relatively sterile environment. Conversely, a deficiency in L-Threonine can impair immune function, increasing the risk of infection and delaying the healing process.

III. Regulating the Inflammatory Response  

Wound healing is a complex physiological process, and inflammation is an important part of this process. However, excessive inflammation can damage wound tissue and hinder healing. L-Threonine helps maintain a balance in the inflammatory response by regulating the production and release of inflammation-related cytokines.  

In the early stages of wound healing, L-Threonine promotes the release of appropriate amounts of inflammatory factors, attracting immune cells to the wound site to clear pathogens and necrotic tissue. In the later stages of inflammation, it suppresses the overproduction of inflammatory factors, reducing damage to surrounding tissues and facilitating the resolution of inflammation. This allows the wound to progress to the next phase of healing.

IV. Providing Energy Support  

Wound healing requires significant energy, as cellular proliferation, migration, and collagen synthesis all demand energy. L-Threonine can participate in energy production through metabolic pathways, providing the necessary energy for wound healing.  

When the body’s energy supply is insufficient, L-Threonine can be converted into glucose through gluconeogenesis, providing energy for the cellular activities involved in wound healing. This ensures that the physiological processes related to wound healing can continue as normal. Without sufficient energy, various stages of wound healing may be impaired, leading to delays in the healing process.

V. Improving Nitrogen Balance  

During wound healing, the body is in a high metabolic state, with increased protein catabolism that can lead to a negative nitrogen balance, which is unfavorable for wound healing and tissue repair. As an essential amino acid, L-Threonine participates in protein synthesis and helps regulate nitrogen balance.  

Adequate intake of L-Threonine increases protein synthesis within the body and reduces protein breakdown, helping maintain a positive nitrogen balance. This provides the necessary protein resources for wound healing and promotes the repair and regeneration of wound tissue.
