NCAM1 and uveitis: T cell (TC: CD3D, IL7R), natural killer cell (NK: NCAM1), B cell (BC: CD79A, MS4A1), monocyte (MC: CD14, LYZ), and dendritic cell (DC: CLEC10A, CD1C) were annotated based on the expression of canonical lineage markers and other genes specifically upregulated in each cluster (Figure2A; Figure S1C,D, Supporting Information), as our previous paper pertaining to uveitis diseases.[26, 27, 28] We used samples from six patients with BU and samples from six HCs as two groups (referred to as the BU group and HC group) for comparative analysis.
