• Genetic Background: involves: 129P2/OlaHsd * C57BL/6J * DBA/2J

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

immune system

decreased thymocyte number ( J:131357 )

• thymocyte numbers are reduced by about 3-fold

abnormal T cell differentiation ( J:131357 )

• the presence of HY TCR alleviates the beta-selection block in Ptcra^tm1Vbo homozygotes with higher T cell numbers being found in the thymus and the spleen

• despite the increased numbers of thymocytes, the CD25⁺ thymocyte sub-population still remains very low

hematopoietic system

decreased thymocyte number ( J:131357 )

• thymocyte numbers are reduced by about 3-fold
