Cancer cells are notoriously plastic, but what triggers the changes in cell state? In our new Nature (@nature.com)‬ paper, Miranda Hunter (@mrndhntr.bsky.social‬) found that mechanical pressure is a key to this switch. Check it out here: go.nature.com/47iwDm2

The Dark Side of NK Cells in Cancer Immunotherapy
Summary:. NK cells are a subset of innate lymphoid cells originally identified in mice and humans based on their ability to mediate cytotoxicity against transformed cells. However, two recent back-to-...

🆕 Our back-to-back papers reveal a surprising villain in ICB resistance: NK cells.

🧬 Targeting regulatory NK cells may boost T cell–driven immunotherapy.

Cytotoxic NK Cells Impede Response to Checkpoint Immunotherapy in Melanoma with an Immune-Excluded Phenotype
AbstractImmune checkpoint blockade (ICB) has revolutionized cancer treatment. Unfortunately, the inability of lymphocytes to infiltrate the tumor nest, a phenomenon known as immune exclusion, drastica...

We have a new preprint out! Led by brilliant PhD student @estefvazquez.bsky.social. here we investigate through transcriptomics and proteomics the microenvironment of ulcerated #acral #melanoma 👇🏾
The microenvironment of ulcerated acral melanoma is characterised by an inflammatory milieu and an enhanced humoral immune response https://www.medrxiv.org/content/10.1101/2025.05.05.25325616v1

Here's the #Cancer #Research #2 starter pack 🤩

Researchers, oncologists, patient advocates & more -working across all aspects of cancer research and treatment 🧪🔬⚕️

I also tried to give some exposure to #PhD #students & #postdocs - randomly picked from followers of me or my lab!

Inspired by the other amazing starter packs - here's one for cancer researchers!

I tried to make this broad - from immunology to genomics to cell biology and so much more..

This list also includes organizations & institutes supporting cancer researchers 🧪🔬⚕️🩺

Hope its useful!
