Abstract excerpt
Surrogate light chains (lambda 5/VpreB) are selectively expressed in early precursors of B cells. B-cell defects in X-linked agammaglobulinemia (XLA) are caused by mutations in the gene for Bruton's tyrosine kinase. To elucidate the nature of early B-lineage cells in bone marrow (BM), samples from 13 XLA patients and 24 healthy controls of different ages were comparatively analyzed using an antihuman VpreB...
