Splenic migration of xid and non-xid splenic B cells.
The X-linked immune deficiency gene (xid) has been viewed as inducing either a deficiency in a B-cell subset or in B-cell maturation. The present experiments were performed in an attempt to better understand whether (a) xid B cells migrate differently from mature and immature non-xid B cells, and (b) whether the failure of mature B cells to be found in xid spleen, but not Peyer's patches, is secondary to migratory differences, especially the possible inability of xid spleens to receive mature B cells. We employed the technique of internally fluorescein labeling donor cells and subsequent injection into recipients. Double labeling permitted analysis of B or T cells by two-color flow microfluorometry. Functional studies revealed that labeled cells appropriately responded to TI-1 and TI-2 antigens after migration. We found that (a) adult xid splenic B cells do not migrate to spleen as well as adult non-xid splenic B cells, (b) the migration of adult xid splenic B cells to spleen resembles that of neonatal (xid and non-xid) B cells, (c) equal masses of xid and non-xid spleens have an equal capacity to receive either xid or non-xid splenic B cells, and (d) the migration of xid and non-xid T cells is similar. These results suggest that xid B cells do not migrate normally, but that migratory differences cannot account for the failure of mature B cells to be found in xid spleens.
