Abstract:La presencia de anticuerpos dirigidos contra los antígenos leucocitarios humanos (Human Leukocyte Antigens, HLA) que se expresan en las células del donante, es uno de los factores de riesgo más importantes asociados con las complicaciones clínicas después del trasplante. La prueba cruzada es una de las pruebas de histocompatibilidad más eficaces para la detección de anticuerpos específicos contra el donante en los receptores de injertos. En los primeros métodos de la prueba cruzada, se utilizaba la citotoxicid… Show more
“…The existence of anti-donor antibodies is usually demonstrated in vitro by incubating serum of a prospective recipient with cells from a prospective donor (cross-matching). Antibody binding to donor cells can be visualized by flow cytometry or by antibody-induced complement activation resulting in cytotoxicity 40,41 . An assessment of the level of anti-pig antibodies by previous cross-match studies has been performed in recent pig-to-human heart and kidney xenotransplantations in deceased human recipients 42,43 .…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
