Cloning the CagA gene of Helicobacter pylori for the production of recombinant CagA protein

open access: yes, 2021
H. pylori infection can lead to the development of peptic ulcer and gastric cancer. Several virulence factors were shown to play a role in the clinical outcome. Among these the cagA gene is one of the major factors involved in pathogenesis. The possession of cagA by certain strains appears to affect the clinical outcome.
