| abstract |
The present invention refers to a bispecific in tandem receptor CAR, named RfuCAR, which includes a scFv that recognizes and ligates surface molecules on tumoral cells (CD33, CD123 or another tumoral target) and the IL-1 receptor type 2 (IL-1R2). According to this, the IL1-R2 was chosen as the ideal receptor to compose the RfuCAR construction, being able to capture the IL-1β with high affinity and specificity. These proprieties indicate it as a good candidate to reduce the neurotoxicity and CRS effects of CAR-T therapies. Additionally, the present invention deals with a method for modulating the tumoral microenvironment, for example, in case of acute myeloid leukemia, or other cancer type like but not restricted to acute lymbloblastic leukemia, pancreatic, lung and ovarian cancer. |
