Expression of TIGIT in T cells elevated in chronic HBV infection. Cryopreserved PBMCs from 50 patients diagnosed with chronic HBV infection and 20 healthy donors were thawed and surface phenotypes were tested for TIGIT expression. (A) Representative flow cytometry flow plots showing TIGIT expression on CD4⁺ and CD8⁺T cells. Graphs show compiled data of TIGIT expression on (B) CD4⁺ and (C) CD8⁺T cells in the HBV-uninfected healthy donors group (HD, black diamond; n=20) and chronic HBV infection group (open diamond; n=50).
