Description
Abstract
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.
