Human Plasmacytoid Dendritic Cells Elicited Different Responses after Infection with Pathogenic and Nonpathogenic Junin Virus Strains

Abstract

The Junín virus (JUNV) arenavirus is the etiologic agent of Argentina Haemorrhagic Fever (AHF). We characterised the JUNV infection of human peripheral blood-derived plasmacytoid dendritic cells (hpDC), demonstrating that hpDC are susceptible to infection by the C#1 strain (attenuated), and even more, by the P (virulent) JUNV strain. However, hpDC elicited different responses in terms of viability, activation, maturation, and cytokine expressions after infection with both JUNV strains.
