Mixed viral and bacterial infections are widely described in community-acquired
pneumonia; however, the clinical implications of co-infection on the associated
immunopathology remain poorly studied. In this study, microRNA, mRNA and
cytokine/chemokine secretion profiling were investigated for human
monocyte-derived macrophages infected in-vitro with Influenza virus A/H1N1 and/or
Streptococcus pneumoniae. We observed that the in-vitro co-infection
synergistically increased interferon-?-induced protein-10 (CXCL10, IP-10)
expression compared to the singly-infected cells conditions. We demonstrated that
endogenous miRNA-200a-3p, whose expression was synergistically induced following
co-infection, indirectly regulates CXCL10 expression by targeting suppressor of
cytokine signaling-6 (SOCS-6), a well-known regulator of the JAK-STAT signaling
pathway. Additionally, in a subsequent clinical pilot study, immunomodulators
levels were evaluated in samples from 74 children (?5 years-old) hospitalized
with viral and/or bacterial community-acquired pneumonia. Clinically, among the
74 cases of pneumonia, patients with identified mixed-detection had significantly
higher (3.6-fold) serum IP-10 levels than those with a single detection
(P?=?0.03), and were significantly associated with severe pneumonia (P?0.01).
This study demonstrates that viral and bacterial co-infection modulates the
JAK-STAT signaling pathway and leads to exacerbated IP-10 expression, which could
play a major role in the pathogenesis of pneumonia.
