Initiation of contact system activation in plasma is dependent on factor XII autoactivation and not on enhanced susceptibility of factor XII for kallikrein cleavage
Various mechanisms have been hypothesized to explain the initiation of contact system activation in plasma. We investigated the capability of dextran sulphate (DS) of different molecular weights to initiate contact system activation in normal human plasma, and compared this with their capability to...

| description | Various mechanisms have been hypothesized to explain the initiation of contact system activation in plasma. We investigated the capability of dextran sulphate (DS) of different molecular weights to initiate contact system activation in normal human plasma, and compared this with their capability to support factor XII autoactivation and to enhance factor XII susceptibility for cleavage by kallikrein.
Dextran sulphate of Mr 500 000 (DS500) and 50 000 (DS50) was able to initiate contact system activation in plasma (determined by measuring the amount of factor XIIa–C1‐inhibitor, kallikrein–C1‐inhibitor and factor XIa–C1‐inhibitor complexes generated) as well as to support factor XII autoactivation and to enhance factor XII susceptibility for cleavage by kallikrein (as measured with amidolytic assays using purified proteins). In contrast, dextran sulphate of Mr 15 000 (DS15) and 5000 (DS5) neither induced contact system activation in plasma, nor supported autoactivation of factor XII, although both of these DS species enhanced the rate of activation of factor XII by kallikrein in the purified system. Based on these properties (i.e. binding of factor XII without inducing autoactivation), DS15 and DS5 were predicted to be inhibitors of contact system activation induced in plasma by DS500, which indeed was observed.
We conclude that enhanced factor XII susceptibility for kallikrein activation and factor XII autoactivation are distinct phenomena, the latter being necessary to support activation of the contact system in plasma. |
