Abstract
Dear Editor,
There are several reports about the modulatory effects of intracellular pathogens, such as Leishmania spp., to help survival and replication inside host cells. They alter host cells' defense and offence mechanisms, and in case of leishmaniasis, the pathogen creates a hostile environment inside macrophages. We performed an RNA sequencing analysis of transcriptome changes in Leishmania major-infected human macrophages at four hour post infection. In this study, we investigated gene expression pattern of the infected macrophages against microbead (4.16 µm) polystyrene particles phagocytized and non-polarized macrophages as controls. Monocytes with high purity were isolated from healthy donors by magnetic-activated cell sorting and then differentiated into macrophages after 6-9 days of incubation at 37 ˚C.
In this study, we focused on some key interaction events between host cell and the pathogen; so some feature steps resulting from dictation strategies of the pathogen are presented below.
