title: An elevation in the concentration of HLA class I molecules in human blood due to ageing.
abstract: The quantification of plasmatic HLA class-I molecules (sHLA-I) was realized by a sandwich ELISA using a monomorphic mAb (W6/32). sHLA-I concentration is significantly increased in the elderly group (>50 years, 0.429+/-0.301 microg ml(-1)) as compared to the young group (<50 years, 0.126+/-0.085 microg ml(-1)). The variation of sHLA-I content could contribute to the unresponsiveness of ageing immune system.
