TRANSGENIC NON-HUMAN ANIMALS DEPLETED IN A MATURE LYMPHOCYTIC CELL-TYPE

摘要

Transgenic mice having a phenotype characterized by the substantial absence of mature T lymphocytes otherwise naturally occurring in said mice. The phenotype is conferred in the transgenic mouse by a transgene contained in at least the precursor stem cell of the T lymphocyte which is depleted. The transgene comprises a DNA sequence encoding a T cell receptor polypeptide variant which inhibits maturation of the T lymphocyte.
