Functional characterization of molecular contacts between hantavirus spikes that control virus particle assembly and spike stability; identification of a temperature-dependent dynamic behavior of the spikes at neutral pH, alternating between ‘open’ and ‘closed’ forms.


Cellular and Molecular Immunology (Mario Rosemblatt, PhD)

Y. Hidalgo, S. Núñez, M.J. Fuenzalida, F. Flores-Santibáñez, P.J. Sáez, J. Dorner, A.M. Lennon-Dumenil, V. Martínez, E. Zorn, M. Rosemblatt, D. Sauma and M.R. Bono. Thymic B cells promote germinal center-like structures and the expansion of follicular helper T cells in lupus-prone mice. Frontiers Immunology, Vol. 11, Article 696, April 2020. doi: 10.3389/fimmu.2020.00696

We found that in the thymus of Lupic mice there is an increased population of B cell that form ectopic germinal centers and produce anti-dsDNA autoantibodies. Thus, the thymus emerges as an important niche that supports the pathogenic humoral response in the development of murine Lupus.


Microbial Ecophysiology (Raquel Quatrini, PhD)

Moya-Beltrán A., Rojas-Villalobos C., Díaz M., Guiliani N., Quatrini R., Castro M. Nucleotide second messenger-based signaling in extreme acidophiles of the Acidithiobacillus species complex: partition between the core and variable gene complements. Front. Microbiol. 10: 381. DOI:10.3389/fmicb.2019.00381 (2019)

In this publication we address the challenge of disentangling the nucleotide-driven signal transduction pathways in the acidophilic bacterial genus Acidithiobacillus, using pangenome-based comparative genomic strategies. Molecular elements of c-di-GMP metabolism and transduction were mostly found scattered along the flexible genome of the acidithiobacilli, allowing the identification of probable control modules that could be critical for substrate colonization, biofilm development and intercellular interactions. Findings presented open new ways to explore molecular circuits to control biomining microorganism behaviours.


Neuroimmunology (Rodrigo Pacheco, PhD)

Ugalde V., Contreras F., Prado C., Chovar O., Espinoza A., Pacheco R. Dopaminergic signalling limits suppressive activity and gut homing of regulatory T cells upon intestinal inflammation. Mucosal Immunol. In press. doi: 10.1038/s41385-020-00354-7 (2020).

Here we provide genetic and pharmacologic evidence indicating how dopaminergic signalling impairs the suppressive activity and the recruitment of Treg into the gut mucosa upon intestinal inflammation.

Growing evidence has revealed a contribution of stress responses in aging. Here, we review the possible interplay between amino acid sensing and redox balance maintenance mediated by the nutritional sensor general control nonderepressive 2 (GCN2).
