CD3D and primary biliary cholangitis: As shown in Fig. 7A, correlation analyses across PBC, PSC, and OC datasets revealed significant positive relationships between hepatic UBD expression and multiple T cell-associated chemokines (CCL18, CCL20, CCL22, CXCL10, CXCL16) as well as chemokine receptors (CCR7, CXCR4), in addition to T cell receptor subunits (CD3D, CD3E, CD3G).
