Gastric mucosal alpha(4)beta(7)-integrin-positive CD4 T lymphocytes and immune protection against helicobacter infection in mice.

abstract：:Interleukin 2, a soluble product of activated T lymphocytes, is of central importance in the development of an appropriate T-cell immune response. Defects in the production of or response to this lymphokine have been described in a variety of immune deficiency and autoimmune states, thus suggesting a role in the patho...
