Abstract
Chronic skin conditions, such as atopic dermatitis, are characterized by a weakened skin barrier and persistent inflammation. Traditional treatments can frequently cause substantial side effects, emphasizing the need for safer alternatives. This study investigated the anti-inflammatory properties of goat meat extract and its effects on improving skin function. We conducted wound healing assays using HaCaT cells and analyzed the expression of key skin barrier-related genes. Additionally, the anti-inflammatory effects of goat meat extract were assessed in HaCaT cells stimulated with TNFα and IFNγ, as well as in LPS-treated RAW264.7 cells. Mechanistic studies focused on the activation of mitogen-activated protein kinase (MAPK) pathways. The results showed that goat meat extract significantly promoted wound closure in HaCaT cells and upregulated the expression of filaggrin, loricrin, and involucrin. The extract also reduced the production of pro-inflammatory cytokines and chemokines in both HaCaT and RAW264.7 cells. Furthermore, it inhibited the activation of the JNK, p38, and ERK pathways in TNFα/IFNγ-stimulated HaCaT cells. These findings suggest that goat meat extract improves skin barrier function and exhibits anti-inflammatory effects, indicating its potential as a therapeutic agent for chronic skin. Further research is required to investigate the in vivo effects of goat meat extract and validate its therapeutic potential.
