Descriptor English: Cross-Priming
Descriptor Spanish: Reactividad Cruzada
Descriptor sensibilización cruzada
Entry term(s) presentación cruzada
Scope note: Activación, restringida a la clase I, de los LINFOCITOS CD8-POSITIVOS como resultado de la PRESENTACIÓN ANTIGÉNICA de ANTÍGENOS exógenos (presentación cruzada). Contrasta con la activación normal de estos linfocitos (sensibilización directa) como resultado de la presentación de antígenos endógenos.

Scope note: Class I-restricted activation of CD8-POSITIVE LYMPHOCYTES resulting from ANTIGEN PRESENTATION of exogenous ANTIGENS (cross-presentation). This is in contrast to normal activation of these lymphocytes (direct-priming) which results from presentation of endogenous antigens.
Annotation: note category, an immunologic process; do not confuse with cross-modality priming (= probably ASSOCIATION LEARNING or other psychology terms)
Allowable Qualifiers: DE drug effects
