 AB    The intestine is largely colonized by bacteria and further exposed to an
       immense array of ingested and shed immunogenic material. Therefore, the
       gut associated lymphoid tissue plays a major role in the human immune
       system. It may even constitute a unique immune system of its own, since
       it has been demonstrated to differ anatomically, phenotypically,
       functionally and on a molecular basis from its systemic counterpart and
       other peripheral lymphoid tissue. This is ultimately reflected by the
       observation in (transgenic) mice that intraepithelial T cells can
       develop independently of the thymus. Along the same lines, a rapidly
       growing body of evidences suggests that human bone marrow precursors can
       home to the gut epithelium, rearrange their T cell receptor genes and
       further differentiate in the mucosal micro environment. This, and other
       features that characterize the 'diffuse' mucosal T cell infiltrate will
       be discussed.
