Type IV secretion systems are common bacterial macromolecule transporters that have been adapted to various functions, such as effector protein translocation to eukaryotic cells, nucleoprotein transfer to bacterial or eukaryotic cells, and DNA transport into and out of bacterial cells. Helicobacter pylori, the causative agent of bacterial gastritis, peptic ulcers, gastric adenocarcinoma and mucosa-associated lymphoid tissue (MALT) lymphoma, uses the Cag type IV secretion system to inject the… CONTINUE READING
