Interaction and Immunological Effect of Very Late Antigen-4, 5, and Fibronectin in Tonsillar Lymphocytes and Their Relation to Age

We examined the expressions of a-subunits of very late antigen (VLA)-4 (oc4) and VLA-5 (a5) on tonsillar lymphocytes and the interaction between these integrin receptors and their ligand, fibronectin (FN). Immunohistological and flow cytometric analyses showed that a 4 and a 5 were expressed in the...
