Evaluation of NanoLuc, RedLuc and Luc2 as bioluminescent reporters in a cutaneous leishmaniasis model.

New drugs for the treatment of human leishmaniasis are urgently needed, considering the limitations of current available options. However, pre-clinical evaluation of drug candidates for leishmaniasis is challenging. The use of luciferase-expressing parasites for parasite load detection is a potentially powerful tool to accelerate the drug discovery process.
