Cholesta-3,5-diene is an inflammatory modulator that targets immune cells such as neutrophils and accelerates wound healing by promoting neutrophil chemotaxis and fibroblast migration. Cholesta-3,5-diene enhances immune cell recruitment and extracellular matrix deposition by activating chemokine receptor-mediated signaling pathways such as PI3K/Akt. Cholesta-3,5-diene can be applied topically to wound repair and has potential therapeutic value in chronic ulcers or skin lesions[1][2].
