    Sammanfattning : In the present thesis, the influence of the immunosuppressive drug FK506 on mitogen-induced changes in the expression of subunits a and ß of the IL-2 receptor by isolated human peripheral blood mononuclear cells has been studied. Up-regulation and release of the a-chain were potently depressed by FK506, even in the presence of exogenous IL-2. LÄS MER

  7. 5. There and Back Again - nocturnal migratory behaviour of birds during spring and autumn

    Författare :Håkan Karlsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; migration; seasons; flight; orientation; navigation; behaviour; strategies; birds; nocturnal;

    Sammanfattning : This dissertation explores the migratory behaviour of nocturnally migrating passerines and common swifts (Apus apus). Birds passing Lund (southern Sweden) and Abisko (northernmost Scandinavia) where sampled using tracking radar. The aim has been to investigate potential diverging strategies between spring and autumn migration. LÄS MER
