title: Determination of soluble interleukin-2 receptor in human seminal plasma.
abstract: Following lymphocyte activation a soluble form of TAC antigen is released. This soluble molecule (soluble interleukin-2 receptor, SIL-2R) seems to corresponds to a truncated extracellular part of the membrane-bound TAC antigen, being smaller than its cellular counterpart. SIL-2R was determined and correlated with PMN elastase levels in the seminal plasma of 79 adult men having different concentrations of PMN elastase (0-700 micrograms/L). The normal level of SIL-2R was detected in the seminal plasma of 15 healthy men. The mean +/- SEM was 101 +/- 29 units/mL. The relation between PMN elastase in human seminal plasma as an index for the state of lymphocyte activity and the sperm motility is also investigated.
