Method for predicting T-cell development stage (and therapy success) (SJ-19-0033)

St. Jude Reference #SJ-19-0033


Researchers at St. Jude have invented a bioinformatic tool that enables accurate prediction of a T cell’s developmental potential – Multipotency Index. This tool was generated by establishing a large collection of DNA methylation profiles from a variety of human CD8 T cells at varying stages of differentiation. From these DNA methylation profiles, a core index was generated that can predict the T cells stage of development. 

This tool can be used by companies that generate T cell-based therapies to identify products that will generate a long-lived robust response to a tumor or chronic infection and characterize the establishment of a long-lived functional memory T cell population that can provide protection against antigen reencounter.
