LINE1 & T cells

Awakening the T lymphocyte response

T-ONE Therapeutics’ goal is to develop more effective therapies to fight cancer and autoimmune diseases.

The breakthrough novelty resides in the identification of LINE1 transcripts as the first of a new class of immune response inhibitors that regulate T cell exhaustion by controlling their gene expression profiles. These results could revolutionise current immunotherapies with novel RNA-based therapies aimed at awakening the T lymphocyte effector response at the transcriptional level.

With our experimental approach we aim to produce new drugs for immunotherapy through the exploitation of antisense oligonucleotides (ASOs), in order to achieve a higher patient response rate and to reduce the side effects reported so far, thus improving patients’ quality of life.
