GIST (Key Takeaways)
- IntroductionInvasive fungal infections (IFI) remain a major therapeutic challenge due to limited antifungal options, emergence of multidrug-resistant (MDR) strains and high mortality rates. This has turned up the development of immune-based therapies to restore and/or enhance anti-fungal immune responses into a clinical priority.
- This is in line with the recent demonstration that antifungal activity of primary (cord blood-derived) NK cells can be potentiated by endowing them with a CD5-based second-generation chimeric antigen receptor (SRCD5CAR) targeting β-glucans, a constitutive and broadly distributed component of fungal cell walls. Building on this, we aimed at exploring whether the reported constitutive antifungal activity of leukemia-derived NK-92 cells can also be potentiated by engineering them for further potential use as a homogeneous and ready-to-use source of allogeneic cells for adoptive transfer therapy in IFI.Methods.
- NK-92 cells lentivirally transduced and selected for stable and high-level expression of the SRCD5CAR for further testing in in vitro fungal killing assays, as well as in an in vivo model of fungal infection. Results.
- SRCD5CAR-NK-92 cells showed superior antifungal activity than untransduced NK-92 cell counterparts.
