The work was led by our talented student Jose Cabezas Caballero (now a postdoc with Mala Maini) and huge thanks to all the co-authors and collaborators who made this work possible, and to Springer Nature Biomedical Engineering for an efficient review process.

Our work shows that by modulating co-signalling receptors on T cells (such as switching CD8 for CD4), we can significantly and selectively reduce lower-affinity off-target activation while keeping higher-affinity antitumor target efficacy intact.

This approach offers a universal method to generate highly selective therapeutic T cells for any TCR, potentially improving both the safety and effectiveness of adoptive immunotherapy for a wide range of targets.

In this study, we explore a novel strategy to enhance the safety of T cell immunotherapies. Traditional engineered T cell receptors (TCR-T) can sometimes cross-react with unintended lower-affinity targets, leading to harmful side effects.

The work was lead by Anna H. with support from many lab members, a fantastic collaboration with Audrey Gerard with support from Wellcome Trust and BBSRC. Thank you to EMBO Journal for a constructive and efficient review process.

We show that despite the enormous molecular complexity at T cell interfaces (with target cells), the 3D affinity measured with purified TCR and pMHC in SPR can accurately predict the OT-I T cell response.

By comparing the advantages and limitations of each platform, we provide a framework to choose the most suitable system to study signal integration in both basic and translational contexts.

In contrast, solid surfaces or supported lipid bilayers allow easy manipulation of ligands but lack the biophysical properties of cells, such as softness, a glycocalyx, and/or ligand mobility.

Immune cells interact directly with other cells and make decisions by integrating information from many different receptor–ligand interactions at these cell–cell interfaces.

Since they encounter a huge variety of normal and abnormal cells, they experience many different combinations and concentrations of ligands. Understanding immune responses therefore requires platforms that enable ligands to be easily manipulated.

The OT-I TCR is often criticised as being very high-affinity and displaying unusual behaviour compared to other TCR transgenics. New work from @tcell.bsky.social shows this might not be the case. Will I still use OT-I and all the wonderful tools associated with it? Yes I will!
