Is the imbalanced mixed lymphocyte reaction between maternal and fetal lymphocytes as well as between the lymphocytes of adult children and their parents mediated by activated CD8+ T cells?
The imbalanced MLR between maternal and fetal lymphocytes and lymphocytes of adult children against their parents is mediated by a specific imbalance of the activation of CD8(+) but not of CD4(+) T cells.
A case is made that the interpretation of RT data may be confounded when expressed in threshold units. Stimulus energy or contrast is the only metric common to the response characteristics of the cells underlying speeded responses. The use of threshold metrics for RT can confuse the interpretation of an underlying physiological process.
