Patterns of Monocyte Differentiation and Activation in a Non-Human Primate Model of Brain Death.
P. Chlebeck, J. Danobeitia, L. Zitur, T. Zens, X. Xu, S. Odorico, A. D'Alessandro, L. Fernandez.
Surgery - Division of Transplantation, University of Wisconsin-Madison, Madison, WI
Brain-death (BD) induces a systemic inflammatory response known to impair tissue perfusion and promote graft immunogenicity. Monocytes play a significant role in the regulation of…
