English Abstract
Cutaneous Leishmaniasis, caused by Leishmania mexicana complex is associated with unpleasant or disfiguring lesions with no available vaccine.
This study aimed to investigate the changes in the gene expression profile of Cytokines (IL-1, IL-6, and TGF-?), and Chemokines (CCL-1, CCL-2, and CCL-5) following infection with avirulent and virulent L.
mexicana promastigote using tumour human MonoMac-6, U937 monocyte and macrophage cell lines by qPCR analysis, Furthermore, the effect of their Soluble Leishmania Antigens was (SLA) also investigated.
Results showed that the level of cytokine/chemokine by parasite infection was both cell line- and parasite-virulence dependent.
Results of this study illustrated that, the gene expression profile IL-1 and IL-6 expression was significantly up regulated in the three cell lines following the avirulent parasite infection.
However, the gene expression of TGF-? was up-regulated following the virulent L.
mexicana infection in U937 macrophages and MonoMac-6 cell lines.
Chemokines CCL-1, CCL-2 and CCL-5 gene expression was down regulated following the infection with L.
mexicana in U937 monocytes and macrophages.
SLA has also an impact on the gene expression profile of ILs and CCLs in stimulated target cells.
For example, the gene expression profile of IL-6 was up regulated after stimulation with avirulent SLA in the three cell line.
In conclusion virulent but not avirulent L.
mexicana promastigote significantly up regulated T helper cells type 2 mediators which supported the parasite surviving inside the host, and this in vitro model of avirulent L.
mexicana parasite has potential role of understanding the parasite pathogenicity.
