Immunohistochemical and Molecular Detection of NK Cells in Kidney Allografts with Antibody Mediated Rejection
E. Farkash, J. Barnes, S. Anand
Pathology, University of Michigan, Ann Arbor, MI
*Purpose: Molecular signatures specific to Natural Killer (NK) cells are closely associated with antibody mediated rejection (AMR) in transplant biopsies. We have developed an immunohistochemical…
