Reina, Ramsés Luján, Lluís Ministerio de Economía y Competitividad (España) Ministerio de Educación, Cultura y Deporte (España) Resumen del trabajo presentado en el XXX Keele Meeting on Aluminium, celebrado en Yucatán (México), del 23 al 27 de marzo de 2019 Aluminium (Al)-containing adjuvants promote an effective immune response but in sheep, they also induce local granulomatous reactions and accumulate in regional lymph nodes1. 21 lambs, divided into 3 groups (n=7 each) were inoculated during 15 months with 19 doses of different substances: A) Vaccines containing Al hydroxide; B) Al hydroxide only; C) PBS. Lumbar spinal cord and frontal lobe of the brain were studied by fluorescence microscopy with lumogallion, Graphite Furnace Atomic Absorption Spectroscopy and immunohistochemistry against glial fibrillary acidic protein (GFAP). Groups A and B showed higher Al concentration in spinal cord than group C (p=0.001). Yellowish fluorescence emission (590 nm), typical of Al, was detected as small aggregates associated to myelin sheets. The highest individual measurements were obtained in group B. GFAP was overexpressed in group B compared to group C (p=0.047). In sheep, Al from adjuvants may translocate from subcutaneous tissue to the CNS, inducing astrocyte activation. This work was funded by grants from the Spanish Ministry of Economy and Industry (AGL2013-49137-C3-1-R and AGL2013-49137-C3-2-R). Asín J is a PhD student funded by the Spanish Ministry of Education, Culture and Sports. 2020-04-16T13:15:46Z 2020-04-16T13:15:46Z 2019-03-23 2020-04-16T13:15:46Z comunicación de congreso http://purl.org/coar/resource_type/c_5794 XXX Keele Meeting on Aluminium (2019) http://hdl.handle.net/10261/207913 http://dx.doi.org/10.13039/501100003329 http://dx.doi.org/10.13039/501100003176 #PLACEHOLDER_PARENT_METADATA_VALUE# #PLACEHOLDER_PARENT_METADATA_VALUE# info:eu-repo/grantAgreement/MINECO/Plan Estatal de Investigación Científica y Técnica y de Innovación 2013-2016/AGL2013-49137-C3-1-R info:eu-repo/grantAgreement/MINECO/Plan Estatal de Investigación Científica y Técnica y de Innovación 2013-2016/AGL2013-49137-C3-2-R Sí open |
