Design outcomes

Primary

MeasureTime frame
This study is initially hypothesis-generating and exploratory in nature. It is conceivable that immune cells from female donors, which may be more effective due to genetic factors, elicit stronger immune responses when exposed to the hormonal environment of male recipients. Conversely, immune cells from male donors may induce weaker immune responses in female patients.

Secondary

MeasureTime frame
Generation of new hypotheses for more detailed analyses of specific cell populations or proteins
