Collagenous Gastritis in Primary Selective IgM Deficiency: Transition to EBV+ Gastric Adenocarcinoma

<div>TFH cells: in PBMCs, CD4+ gated cells and various TFH subsets were characterized by different makers: cTFH-CXCR5+CD45RA- and TFH subsets TFH1 (CXCR3+CCR6-), THF1+THF17 (CXCR3+CCR6+), TFH2 (CXCR3-CCR6), and TFH17 (CXCR3-CCR6+). Abnormal values are circled in red. (a) CD4+T-cell subsets. (b) CD8+T-cell subsets.</div>
