Together, we propose a causal, spatial mechanism for how inflammatory stromal niches grant non-genetic access to therapy-resistant, metastatic cell fates — and a mechanistic rationale for COX inhibition (aspirin/celecoxib) in both preventing and treating CRC. (7/7)

This paper was led by Corinne Molyneux and Rhianna O'Sullivan and supported by many in Tape Lab, plus CRC-STARS collaborators Eoghan Mulholland-Illingworth, Joshua Moore, and Simon Leedham,Raheleh Amirkhah, and Philip Dunne — plus Smita Krishnaswamy and Jeroen Claus, who added their usual magic.

Full factorial analysis revealed that PGE2 is the dominant CAF regulator of CRC cell-fate. PGE2 rapidly and reversibly converts chemosensitive proliferative colonic stem cells (proCSCs) into chemorefractory, pro-metastatic revival colonic stem cells (revCSCs). (5/7)

PTGS2+ CAFs map an epithelial plasticity gradient with increasing DACH1 in human CRC tumours. Specifically, epithelia <200 µm from PTGS2+ CAFs are revCSC and epithelia >200 µm are proCSC — linking stromal prostaglandin to poor-prognosis cell-fates in vivo. (6/7)

We developed a way to quantify CAF-induced plasticity in CRC epithelia and found that the transcriptional co-repressor DACH1 marks which cells are susceptible to CAFs: DACH1+ epithelia respond to stromal signals, DACH1– epithelia don't. (3/7)

We then built a single-cell arrayed CRISPR platform to interrogate native cell-cell communication. By perturbing the CAF secretome and measuring epithelial plasticity response, we identified CAF PTGS2 (COX2), HGF, GREM1, and IL1R1 as regulators of cell-fate. (4/7)

In early-2025 I was reeling from a ‘scored fundable’ grant application that was not funded. I really believed in this grant and knew the ideas were good but the review panel just weren’t into the project and there nothing more I could do. That’s science, but it hurts. (1/8)

In December we pitched the project to the Cancer Grand Challenge committee in New York. At this point we’d spent so much time together that the team felt like a scientific family and I think that came across during the interview. (7/8)

Today, one year on from that failed grant application and Bart’s ‘shall we explore?’ email, I am very proud to share that REWIRE-CAN has been supported by Cancer Grand Challenges. Never give up on an idea you believe in. (8/8)

We brought together world-leaders in signalling activators (Bill Sellers, Roger Williams, Madelon Maurice, Steve Wedge) with experts in cancer cell models and signalling dynamics (Karuna Ganesh, Vivian Li, Smita Krishnaswamy) to form team REWIRE-CAN. (5/8)

For the next 9 months we worked together to create our Cancer Grand Challenge proposal. We went through many, many iterations — but learnt something new from every discussion and built something that none of us could ever have conceived alone. (6/8)

Our idea was to use novel ‘activator’ drugs to ‘re-wire’ cancer cell signalling. This new class of therapies aim to turn the extreme signalling dependencies of cancer cells against them by hyper-activating signalling. We could also use activators to move cancer cells into vulnerable states. (3/8)

These ideas had some striking technical overlap with my unfunded grant proposal so the project fundamentals came together very quickly. Failure of the first grant became information for the next. (4/8)

(1/N) Thrilled to share that our paper HiPoNet (High dimensional Point cloud Network) to be presented at NeurIPS 2025! HiPoNet treats an entire high-dimensional point cloud as a datapoint! It captures multi-scale geometry and topology of the cloud perform classification and regression tasks.

In summary, these results suggest that γδ T cell multimodal cytotoxicity can buffer γδ T cell signalling from patient-specific cancer cell immunomodulation, allowing γδ T cells from a range of donors to kill chemorefractory cancer cells. (12/13)

To confirm that the anti-B7-H3 antibody was only inducing ADCC and not invoking the putative immune checkpoint properties of B7-H3, we also demonstrated that only a complete IgG — and not an Fc-null IgG — could trigger multimodal killing. (9/13)

CRC PDOs comprise an admixture of chemosensitive proliferative colonic stem cells (proCSCs) and chemorefractory revival colonic stem cells (revCSCs). Crucially, stIL-15-γδ T cells can kill PDOs irrespective of stem cell admixture — including chemorefractory PDOs. (10/13)

We found that γδ T cells can kill both MSS and MSI CRC PDOs. However, when γδ T cells only use AIC, γδ T cell signalling converges on the target PDO, irrespective of T-cell donor. This suggests that γδ T cells are immunomodulated by PDOs and ITH is dominant over IDH. (7/13)

Importantly, PDO immunomodulation of γδ T cells correlates with reduce AIC killing (i.e. the more PDOs change γδ T cell signalling, the worse γδ T cells kill). However, when γδ T cells also use AIC + ADCC, PTM signalling was restored and γδ T cells could kill all PDOs. (8/13)

Next, we found that stIL15-engineered γδ T cells can rapidly kill MSI colorectal cancer (CRC) patient-derived organoids (PDOs) in 3D via AIC. Killing could be further increased by inducing ADCC via a novel anti-B7-H3 antibody — demonstrating multimodal cytotoxicity. (5/13)

To investigate how γδ T cells from various T-cell donors (IDH) kill cancer cells from a range of CRC patients (ITH) via AIC and ADCC, we performed single-cell signalling analysis of γδ T cells from x4 donors co-cultured with x10 CRC PDOs, +/- B7-H3 mAb (x780 3D cultures). (6/13)

To explore this, we performed a systematic single-cell phenoscaping study of >1,000 organoid cultures testing the combinatorial interactions between γδ T cell killing modalities (AIC vs ADCC), γδ T cell inter-donor heterogeneity, and cancer cell inter-tumour heterogeneity. (3/13)

First, we found that expressing stabilised IL-15Rα–IL-15 (stIL15) enables γδ T cells to survive in 3D cultures without serum or cytokine support. This is important because many T-cell killing assays are performed in 2D with serum, but tumours are 3D and nutrient-deprived. (4/13)

γδ T cells can kill cancer cells via antibody-independent cytotoxicity (AIC) and antibody-dependent cellular cytotoxicity (ADCC), but how this killing varies across T cell donors (inter-donor heterogeneity, IDH) and patients (inter-tumour heterogeneity, ITH) is unclear. (2/13)
