Cutting Edge: A possible role for CD4+ thymic macrophages as professional scavengers of apoptotic thymocytes.
A vast majority of thymocytes are eliminated during T cell development by apoptosis. However, apoptotic thymocytes are not usually found in the thymus, indicating that apoptotic thymocytes must be eliminated rapidly by scavengers. Although macrophages and dendritic cells are believed to play such role, little is known about scavengers in the thymus. We found that CD4(+)/CD11b(+)/CD11c(-) cells ...
متن کاملIn vitro evidence for participation of DEC-205 expressed by thymic cortical epithelial cells in clearance of apoptotic thymocytes.
Binding of apoptotic cells was compared after incubation of thymocytes with two clones of murine thymic stromal cells to which CD4(+)/CD8(+) thymocytes attach. With the BA/10, but not the BA/2, clone, thymocytes with apoptotic morphology were bound irreversibly. These tightly bound thymocytes were further identified as apoptotic in terms of active caspase-3 and DNA fragmentation assayed in situ...

15 صفحه اولPurification and properties of DNase γ from apoptotic rat thymocytes
We previously identified three distinct DNA endonucleases, DNases α, β and γ, present in rat thymocyte nuclei. On the basis of their enzymic and biochemical properties, γ-type DNase was regarded as a candidate for the apoptotic endonuclease. Here we purified DNase γ to apparent homogeneity from apoptotic rat thymocyte nuclei induced by X-irradiation and characterized its properties in detail. T...
