Immunohistochemical Study of Lymphocyte Populations Infiltrating the Gastric Mucosa of Beagle Dogs Experimentally Infected with Helicobacter pylori

Experimental infection of beagle dogs with Helicobacter pylori induces recruitment to the gastric mucosae of neutrophils at early stages and later of mononuclear cells that organize into lymphoid follicles. These structures become macroscopically evident and consist of peripheral CD4(+) T lymphocyte...

Descrição
Resumo:Experimental infection of beagle dogs with Helicobacter pylori induces recruitment to the gastric mucosae of neutrophils at early stages and later of mononuclear cells that organize into lymphoid follicles. These structures become macroscopically evident and consist of peripheral CD4(+) T lymphocytes and central CD21(+) B lymphocytes. Furthermore, transient expression of interleukin-8 (IL-8) parallels the presence of neutrophils in the gastric mucosae, whereas expression of IL-6 tends to persist chronically.
