title: Lymphocyte migration through the walls of the post-capillary venules.
abstract: The results of morphological analyses of the direction of the lymphocyte traffic through the walls of the HE-venules are conflicting. The aim of this paper is to provide a short analytical review of the evidence available for the bi-directional hypothesis and for the uni-directional hypothesis.
