Helicobacter pylori-infected human neutrophils exhibit impaired chemotaxis and a uropod retraction defect

Frontiers in Immunology, 2022
Helicobacter pylori is a major human pathogen that colonizes the gastric mucosa and plays a causative role in development of peptic ulcers and gastric cancer. Neutrophils are heavily infected with this organism in vivo and play a prominent role in tissue
