The effects of CTX damage or inhibition of bone marrow hematopoiesis and GM-CSF stimulation of bone marrow hematopoiesis on the peripheral blood TCR β CDR3 repertoire of BALB/c mice.

Conclusions: These data reveal that CTX significantly reduced the number of WBCs and ratio of high-frequency TCR CDR3 sequences, and indirectly increased the diversity of the TCR CDR3 repertoire. GM-CSF quickly restored the number of WBCs, and partially restored changes in the TCR CDR3 repertoire induced by CTX. Results from monitoring the dynamic changes of the TCR CDR3 repertoire can be used to assess the effects of CTX and GM-CSF on the function of peripheral blood T cells and to explore the possible underlying mechanisms.
