Bono Merino, María Rosa; Reyes, Lilian I.; Rosemblatt Silber, Mario César (1999)We present a simple non-radioactive cytometry-based assay that permits the simultaneous quantitation of cell adhesion of distinct subsets of cells contained in a mixture without any previous fractionation. The procedure ...

Sauma Mahaluf, Daniela; Crisóstomo, Natalia; Fuentes, Camila; Gleisner, María Alejandra; Hidalgo, Yessia; Fuenzalida, María José; Rosemblatt Silber, Mario César; Bono Merino, María Rosa (Springer, 2017)Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by increased autoantibody production that leads to multiple tissue injuries. Dendritic cells (DCs) are important orchestrators of immune responses ...

Rosemblatt Silber, Mario César; Fellous, A.; Mazie, J. C.; Delacourte, A.; Defossez, A. (1989)In Alzheimer's disease, the most characteristic neuropathological changes are the formation of neurofibrillary tangles (NFT) and neuritic plaques (NP) characterized by the presence of bundles of paired helical filaments ...

Pino Lagos, Karina; Michea, Paula; Sauma Mahaluf, Daniela; Alba, Andrea; Morales, Jorge; Bono Merino, María Rosa; Fierro, Alberto; Rosemblatt Silber, Mario César (Society of Biology of Chile, 2010)One of the mechanisms for generation of tolerance involves immature dendritic cells (DCs) and a subpopulation of regulatory CD4+ CD25+ T lymphocytes (TREG). The purpose of this work was to analyze how Cyclosporine A (CsA), ...

Gleisner, M. A.; Rosemblatt Silber, Mario César; Fierro, J. A.; Bono Merino, María Rosa (2011)Background: Dendritic cells (DCs) are professional antigen-presenting cells able to induce immunity or tolerance. The interactions of immature DCs with naive T lymphocytes induce peripheral tolerance through mechanisms ...

Moore, C.; Sauma Mahaluf, Daniela; Reyes Pérez, P. A.; Morales Peña, José; Rosemblatt Silber, Mario César; Bono Merino, María Rosa; Fierro, J. A. (ELSEVIER, 2010)Background. CD4 CD25 Foxp3 regulatory T cells (Treg) play an essential role in immune tolerance, suppressing responses against self-antigens. Additionally, Treg play an important role in maintaining immunosuppression ...

Salas Cortés, Laura; Jaubert, Francis; Bono Merino, María Rosa; Fellous, Marc; Rosemblatt Silber, Mario César (2001)Sex determination in mammals is controlled by the SRY gene located on the Y chromosome. It encodes a protein containing a DNA-binding and DNA-bending domain. In spite of recent advances in the identification of the mechanisms ...

Castro, Andrea; Bono Merino, María Rosa; Simon, Valeska; Rosemblatt Silber, Mario César (Elsevier GmbH, 1996)The development of an efficient immune response depends on the capacity of antigen-specific lymphocytes to migrate into secondary lymphoid organs. The first step in the process of lymphocyte extravasation involves lymphocyte ...

Naves, Rodrigo; Reyes, Lilian I.; Rosemblatt Silber, Mario César; Jacobelli, Sergio; González, Alfonso; Bono Merino, María Rosa (2006)Immune surveillance depends on still poorly understood lymphocyte-endothelium interactions required for lymphocyte transendothelial migration into secondary lymphoid organs. The nuclear factor κB (NF-κB) regulatory system ...
