PROBLEM:  In contrast , attempts to correlate glucocorticoid receptor levels in acute lymphocytic leukemia to in vivo steroid responsiveness and immunological type using the whole - cell - binding assay for receptor determination and selecting the patients according to age and immunological criteria have been more successful .

SOLUTION: glucocorticoid receptor

PROBLEM:  Although many of these transcription factors have putative roles based on murine knockout experiments , their function in human lymphoid development is less known and was studied further .

SOLUTION: transcription factors

PROBLEM:  These data suggest that the IL - 2 and CD3 signaling pathways provide a necessary and co - operative stimulus promoting phosphorylation of CREB following receptor cross - linking .

SOLUTION:
IL - 2
