Journal ArticleDOI

Rita Reynoso,Natalia Laufer,Matthias Hackl,Susanna Skalicky,Rossella Monteforte,Gabriela Turk,Mauricio Carobene,Jorge Quarleri,Pedro Cahn,Roland Werner,Heribert Stoiber,Regina Grillari-Voglauer,Johannes Grillari +12 more
TL;DR: Levels of circulating miRNAs might be of diagnostic and/or prognostic value for HIV infection, and hsa-miR-29b-3p and miR-33a-5p may contribute to the design of new anti-HIV drugs.
Journal ArticleDOI

TL;DR: In this article, the authors evaluated SARS-CoV-2-specific antibody responses after Sputnik V vaccination of healthcare workers in Argentina, measuring IgG anti-spike titers and neutralizing capacity after one and two doses in a cohort of naive or previously infected volunteers.
Journal ArticleDOI
Early Gag Immunodominance of the HIV-Specific T-Cell Response during Acute/Early Infection Is Associated with Higher CD8+ T-Cell Antiviral Activity and Correlates with Preservation of the CD4+ T-Cell Compartment
Gabriela Turk,Yanina Alexandra Ghiglione,Juliana Falivene,María Eugenia Socías,Natalia Laufer,Romina Soledad Coloccini,Ana M. Rodríguez,María Julia Ruiz,María A. Pando,Luis D. Giavedoni,Pedro Cahn,Omar Sued,Horacio Salomón,María Magdalena Gherardi +13 more
TL;DR: The importance of CD8+ T-cell specificity in the improved control of disease progression was related to the capacity of Gag-specific cells to mediate both lytic and nonlytic antiviral mechanisms at early time points postinfection.
Journal ArticleDOI
Acute retroviral syndrome and high baseline viral load are predictors of rapid HIV progression among untreated Argentinean seroconverters
M. Eugenia Socías,Omar Sued,Natalia Laufer,María Esther Lázaro,Horacio Mingrone,Daniel Pryluka,Carlos Remondegui,María Inés Figueroa,Carina Cesar,Ana Gun,Gabriela Turk,María Belén Bouzas,Ravi Kavasery,Alejandro J. Krolewiecki,Héctor Pérez,Horacio Salomón,Pedro Cahn +16 more
TL;DR: In Argentina, PHI is associated with significant morbidity and HAART should be considered in PHI patients with ARS and high baseline VL to prevent disease progression, according to a multicentre registry of patients diagnosed between 1997 and 2008.
Journal ArticleDOI
Th17 and Th17/Treg ratio at early HIV infection associate with protective HIV-specific CD8 + T-cell responses and disease progression
Juliana Falivene,Yanina Alexandra Ghiglione,Natalia Laufer,María Eugenia Socías,María Pía Holgado,María Julia Ruiz,Cynthia Maeto,María Inés Figueroa,Luis D. Giavedoni,Pedro Cahn,Horacio Salomón,Omar Sued,Gabriela Turk,María Magdalena Gherardi +13 more
TL;DR: Positive correlations between Th17 at baseline and anti-HIV CD8+ T-cell functionality: viral inhibitory activity (VIA) and key polyfunctions (IFN-γ+/CD107A/B+) at both early and later times p.i are found, highlighting the prognostic value of Th17 cells to preserve an effective HIV T- cell immunity.
