Pivotal Advance: Up-regulation of acetylcholine synthesis and paracrine cholinergic signaling in intravascular transplant leukocytes during rejection…
2009
Abstract A new role and source of the old mediator acetylcholine is described, which is produced by graft monocytes and attenuates monocytic ATP-signaling. During acute rejection, large numbers of leukocytes accumulate in the blood vessels of experimental renal allografts. About 70% of them are activated, cytotoxic monocytes that appear to be involved in allograft destruction. ACh exerts anti-inflammatory effects upon monocytes/macrophages and has been proposed to be a key player in neuroimmunological interactions. Its short half-life, however, makes it unlikely that neuronal ACh affects blood leukocytes. Renal transplantation was performed in the allogeneic DA to LEW and in the isogeneic L…
Trägt leukozytäres Acetylcholin zur chronischen Abstoßung von Nierentransplantaten bei?
2010
Einleitung: Akute Abstoßungsepisoden prädisponieren für die chronische Abstoßung von Nierentransplantaten. Für die fatale akute Abstoßung haben wir experimentell gezeigt, dass Monozyten, die sich in Transplantatgefäßen massiv ansammeln, Acetylcholin (ACh) produzieren.[for full text, please go to the a.m. URL]
