To determine the chemokine receptor expression profile in gastric mucosa-associated lymphoid tissue (MALT) lymphoma, we performed an expression analysis of 19 chemokine receptors at mRNA levels by using real-time RT-PCR, as well as of five chemokine receptors--CCR8, CCR9, CXCR4, CXCR6 and CXCR7--by immunohistochemistry on human tissue samples of Helicobacter pylori-associated gastritis, gastric MALT lymphoma and gastric extranodal diffuse large B-cell lymphoma originating from MALT lymphoma (transformed MALT lymphoma).
