    The diffusely-infiltrated lymphoid tissue of the bursa of fabricius of Sturnus unicolor. Histological organization and functional significance
    (Murcia : F. Hernández, 1994) Fonfría Díaz, José; Moreno, J.; Gomez del Moral, M.; Alonso, L.M.; Zapata, A.G.
    In the present study we confirm and extend previous reports about the existence of a T-dependent area in the bursa of Fabricius of some birds, analyzing ultrastructurally the cell content of the so-called diffusely-infiltrated lymphoid tissue of the bursa of the spotless starling, Sturnus unicolor. I t consists of lymphocytes, plasma cells, macrophages (MW) and interdigitating cells (IDCs) in a supporting reticular stroma which, apart from blood capillaries, contains postcapillary high-endothelial venules (HEVs). The presence of both IDCs and HEVs confirms the T-celldependent nature of this area, as previously claimed for other avian species, and emphasizes other functions. apart from its role in B-cell maturation, for the bursa of Fabricius specially in adult birds.
