Detección de antígenos del virus dengue en tejidos post mortem

Abstract: El panorama epidemiológico del dengue ha empeorado durante la última década. Las dificultades para prevenir su transmisión, así como la ausencia de una vacuna o tratamiento específico, lo convierten en un riesgo que desafía las medidas de salud pública y desborda la capacidad de los centros de salud y los sistemas de investigación a muchos niveles. Actualmente, la mayoría de los estudios sobre la patogenia de la infección centran su atención en la respuesta inmunitaria de las células T casi exclusivamente en i… Show more

“…DENV-2 antigens in infected BALB/c mice have been previously shown in liver, a susceptible viral replication site, specifically in hepatocytes, endothelial cells and in hyperplasic Kupffer cells [16,17,87]. In humans, the detection of the DENV-3 NS3 protein has been shown in liver (in hepatocytes, endothelial cells and Kupffer cells), in lung (in alveolar macrophages, type II pneumocytes and endothelium) and in heart (in cardiac fibers, endothelium and monocytes) [8,88]. In this study, the NS3 viral protein was detected in hepatocytes, pneumocytes and cardiomyocytes, demonstrating the presence of the virus in liver, lung and heart and suggesting viral replication, which would only be possible in the presence of the NS3 protein [15].…”

“…Fueron identificados antígenos virales en hígado, tejido linfoide, cerebro, bazo, riñón, pulmón, miocardio, sistema nervioso central, médula osea, páncreas y corazón y proteínas no estructurales (NS) del virus NS3 y NS1 y de la envoltura (E) fueron observadas en hígado, pulmón, corazón, bazo y nódulos linfáticos (9,10, 12,14,15,17,18,[20][21][22][23][24]26). …”

“…En el bazo los hallazgos más comunes son congestión, hemorragias y atrofia de folículos linfoides, infiltrados de mononucleares, necrosis y esplenitis aguda (10, 13,14,19,20,22,24,28). Hay presencia de antígeno viral en macrófagos circulantes de la pulpa roja, células multinucleadas y linfoides (22).…”
