Fecha de publicación: | ago-2020 | Editor: | Elsevier | Citación: | Developmental and Comparative Immunology 109: e103692 (2020) | Resumen: | Dendritic cells are professional antigen-presenting cells that play a critical role in the development of immune responses. DCs express a variety of Siglecs on their surface, which play a regulatory role modulating their activation through interaction with sialylated structures expressed by cells or pathogens. Here, we characterized the phenotype of porcine conventional dendritic cells subsets from blood, spleen and lymph nodes, emphasizing the analysis of the expression of Siglecs. Siglec-1 was detected in type 1 cDC and, at lower levels, in type 2 cDC in the spleen, being low to negative in blood and lymph node cDC. Siglec-3 and Siglec-5 were expressed in cDC1 at lower levels than in cDC2. Porcine cDCs did not express Siglec-10. cDC2 showed a higher capacity to phagocytose microspheres and to process DQ™-OVA than cDC1, but none of these functions was affected by engagement of Siglec-3 and -5 with antibodies on blood cDC. | Descripción: | 8 Pág. | Versión del editor: | https://doi.org/10.1016/j.dci.2020.103692 | URI: | http://hdl.handle.net/10261/339462 | DOI: | 10.1016/j.dci.2020.103692 | ISSN: | 0145-305X |
