IL-17 expression is often associated with a specific subset of CD4+ T cells and CD8+ T cells (40), CD4+T cells and CD8+T cells under particular conditions acquire the expression of Inflammatory factors (41), To delve deeper into the involvement of immune cells in BD, we utilized the CIBERSORT deconvolution method to analyze gene expression differences between BD patients and healthy controls. This evidence concerns the gene CD8A and Behcet disease.
