Since we found two IFN-γ, five IL-4, four IL-10 inducing epitopes, and five epitopes that induce pro-inflammatory responses within our protein, these properties point to a recombinant multi-epitope protein that can be used in a cytokine production assay, similar to the aforementioned IGRA, being able to detect different cellular immune profiles associated to different clinical manifestations of leprosy. Here, IL4 is linked to leprosy.
