In Lutzner cells, there is a mutation in the T-cell receptor that inhibits antigens like CD8 and CD7, but stimulates the over production of other antigens like CD4. This mutation is a clonal gene rearrangement at the TCR-γ gene. Clonal gene rearrangements create novel or new surface antibodies during early differentiation. [2]
