A Rapid Method of Isolating Neoantigen-specific T Cell Receptor Sequences

A Rapid Method of Isolating Neoantigen-specific T Cell Receptor Sequences

Summary
Recent research has demonstrated that neoantigen-specific T-cell receptors (TCRs) can be isolated from a cancer patient’s lymphocytes. These TCRs may be used to engineer populations of tumor-reactive T cells for cancer immunotherapies. Obtaining sequences of these functional TCRs is a critical initial step in preparing this type of personalized cancer treatment; however, current methods are time-consuming and labor-intensive. Scientists at the National Cancer Institute (NCI) have developed a rapid and robust method of isolating the sequences of mutation-specific TCRs to alleviate these issues; they seek licensing and/or co-development research collaborations for the development of a method for isolating the sequences of tumor-reactive TCRs.

Description of Technology

Tumors can develop unique genetic mutations which are specific to an individual patient. Some of these mutations are immunogenic; giving rise to autologous T cells which are tumor-reactive. Once isolated and sequenced, these neoantigen-specific TCRs can form the basis of effective adoptive cell therapy cancer treatment regimens; however, current methods of isolation are inefficient. Moreover, the process is technically challenging due to TCR sequence diversity and the need to correctly pair the a and b chain of each receptor. Thus, there is an urgent need for more robust methods of identifying paired sequences of mutation-specific TCRs for cancer immunotherapy.

Researchers at the NCI have developed an efficient method for isolating the paired sequences of TCRs. Using single-cell methodology, next generation sequencing and custom bioinformatics software, the researchers can isolate full-length TCR α and β chain sequences from mutation-reactive T cells. These isolated sequences can facilitate adoptive cell therapy for cancer patients.
