xénoréactif

santé - iate.europa.eu
Si les cellules du donneur n'expriment pas B7, ou si B7 est bloqué, les lymphocytes T du receveur xénoréactif deviennent anergiques.

The donor cells are thus able to present xenoantigens to a recipient T-cell in the context of self-MHC class II. If the donor cells do not express B7, or if B7 is blocked, the xenoreactive recipient T-cell becomes anergic.

Modulation of eicosanoid metabolism in endothelial cells in a xenograft model. role of cyclooxygenase-2.... To evaluate how complement might influence eicosanoid metabolism, we investigated endothelial cells exposed to xenoreactive antibodies and complement, as might occur in rejecting xenografts where severe vascular injury is a typical feature....
