  sub:assertion dcterms:description "[Here we show the existence of a soluble form of CD137 (sCD137) of 16 kDa. sCD137 is released by activated lymphocytes, and in contrast to membrane-bound CD137, expression of sCD137 seems to be restricted to lymphocytes. sCD137 is generated by alternative splicing and two splice variants were identified. sCD137 is present at low levels in sera of some healthy donors (5/12; mean = 0.18 ng/ml) and is significantly enhanced in sera of patients with rheumatoid arthritis (12/12; mean = 3.58 ng/ml).].
