NextCore is our unique drug development platform.
NextCore mimics the pivotal interaction between Antigen Presenting Cells (APC) and T helper cells (Th)
Harnessing the core of T cell immunity
T helper cells are the converging point in the adaptive immune cascade where they upon stimulation by HLA II molecules displaying peptide antigens orchestrate activation of other immune effector cells
Developing drugs that focus on these HLA II interactions will lead to a new level of specificity in therapeutic development – therapies that focus on the core of autoimmune and chronic diseases, as well as unique point of attack in cancer immunotherapy
NextCore allows for the first time to bring this drug and target space into a recognized industrial application building on next generation phage display technology
NextCore-HLA has a unique capacity to generate large combinatorial libraries of peptide HLA class II repertories enabling novel target discovery in a segment that previously was impossible
NextCore drug discovery platform facilitates development of cognate drugs targeted towards HLA cell surface markers. We have successfully developed TCRs and TCR-like antibodies with unique binding specificities for autoimmune antigens suitable for both ACT and antibody-based therapies such as ADC.
NextCore-HLA: Highly diversified antigenic peptide libraries (>1010) displayed on phages in the context of relevant HLA class II
Mix with disease relevant T-cells from patients
Recover the complexes that are bound. The receptor of the T-cells (TCR) is the target for the HLA II with the right antigenic peptide
Deciphering the antigenic peptide by using deep sequencing
