abstractText | We have identified three distinct populations of mouse lymph node dendritic cells (DC) that differ in their capacity to uptake Ag delivered by different routes, and in their dynamics. The I-DCs are large cells that resemble the interdigitating cells and have a mature phenotype and a slow turnover. They derive from the regional tissues. The sm-DCs and sI-DCs are smaller (hence s-DC), have a more immature phenotype and a rapid turnover. The sI-DC phenotype, including CD8alpha expression suggests a lymphoid-related origin. The sI-DC population is expanded 100-fold after an in vivo flt3 ligand treatment. The sm-DC phenotype suggests a myeloid-related origin. Interestingly, sm-DCs can acquire i.v. injected macromolecules in less than 30 min after injection. They may, therefore, play an important role in the immune response against blood Ags. |
