The CARDS toxin of Mycoplasma pneumoniae induces a positive feedback loop of type 1 immune response
ConclusionsOur findings suggest that CARDS toxin induces a type 1 immune response positive feedback loop during M. pneumoniae infection; this putative mechanism may be useful in future investigations of immune intervention approaches for M. pneumoniae pneumonia.

Immune-Modulation by the Human Respiratory Syncytial Virus: Focus on Dendritic Cells
This study is complemented by another report that found that hRSV infection induces significant expression of three miRNAs, namely hsa-miR-4448, hsa-miR-30a-5p, and hsa-miR-4634 in human DCs (104). Interestingly, this latter study also performed comparative analyses of miRNA profiles between DCs infected with hRSV and a related virus, namely the human metapneumovirus, and found that both viruses induced the expression of elevated levels of hsa-miR-4634. Elucidating the contribution of these miRNAs in DCs in response to hRSV remains to be determined. Dendritic Cell Phenotype and Migration Upon hRSV Infection in vivo Altho...
