Skin health depends on a balanced immune response. Dysregulated or excessive inflammatory signaling can contribute to sensitive, reactive and inflammation-prone skin and is also a central feature of inflammatory skin conditions such as atopic dermatitis and psoriasis.
Semaphorin 3A (Sema3A) is a naturally occurring immune-regulatory protein involved in controlling inflammatory responses and supporting regulatory immune-cell function. Sema3A has been associated with immune regulation across multiple inflammatory and autoimmune conditions, including atopic dermatitis.
A proprietary modified form of Sema3A (T-Sema3A) was engineered to retain the immune-regulatory properties of the natural protein while selectively altering its receptor interactions. T-Sema3A retains signaling through the immune-regulatory CD72 pathway while avoiding neuropilin-1-mediated activity, which is associated with additional biological functions of native Sema3A. The modified protein promotes regulatory immune activity, including IL-10 expression, and is smaller than the native protein, potentially facilitating production and formulation.
These properties provide an opportunity to explore T-Sema3A as a novel bioactive for topical skin applications aimed at supporting immune balance and controlling excessive inflammatory responses, with potential relevance to sensitive and inflammation-prone skin.
