Restricted expression of p55 interleukin 2 receptor (CD25) on normal T cells.
Using a phycoerythrin-conjugated antibody to the p55 chain of the interleukin 2 receptor, normal blood lymphocytes were found to be on average 30% positive for this marker. Two-thirds of these cells are in the CD4 subset and most are within the CD45RA negative fraction associated with activated or memory T cells.
