#neoantigens
To develop a workable mRNA vaccine, Greenbaum and Balachandran had to both
sequence the DNA of the cancerous tumors they were targeting
and develop a framework for going after the right #neoantigens
—those abnormal proteins that offer clues to a tumor’s underlying mutations.

Neoantigens are […]

A 𝐧𝐞𝐨𝐚𝐧𝐭𝐢𝐠𝐞𝐧 is a novel peptide that is derived from a somatic variant in a tumor cell and can be recognized as “nonself” by T cells. Neoantigens are tumor-specific and have not been encountered during thymic T-cell development and are therefore not subject to central tolerance.

A Phase 1 trial applies the Mirasol process to ovarian cancer. UV light and riboflavin inactivate tumor DNA while preserving neoantigens.

This whole-cell vaccine aims to bypass antigen prediction challenges in immunotherapy.

Elegant proof that a DNGR-1–dependent mechanism isn’t just sensing tumors but editing them in carcinogenesis

A key point is that the effect is qualitative not quantitative—same mutation burden but selective loss of neoantigens = immune pressure

Thanks for sharing @drjonlim.bsky.social & congrats 🥳

This suggested that DNGR-1–dependent cross-presentation preferentially reveals cytoskeletal neoantigens, placing immune pressure on tumours to lose them ⚖️.

We tested this directly 🔬.

Some predicted F-actin–binding protein neoantigens were:
✔️ able to bind MHC I
✔️ genuinely immunogenic 𝘪𝘯 𝘷𝘪𝘷𝘰

So we revisited earlier work (led by @giampazolias.bsky.social 👨‍🔬🌟) and hypothesised that DNGR-1 might shape specific classes of neoantigens.

A new AI model predicts B cell reactivity to neoantigens, enabling the design of personalized cancer vaccines that may provide long-term immune memory and reduce cancer recurrence.
AI model predicts B cell reactivity to neoantigens for improved cancer vaccines
Neoantigens are unique markers that distinguish only cancer cells. By adding B cell reactivity, cancer vaccines can move beyond one-time attacks and short-term memory to become a long-term immunity that "remembers" cancer, effectively preventing recurrence.

Neoantigens are unique markers that distinguish only cancer cells. By adding B cell reactivity, cancer vaccines can move beyond one-time attacks and short-term memory to become a long-term immunity that "remembers" cancer, effectively preventing recurrence. KAIST's research team has developed an AI-based personalized cancer vaccine design technology that makes this possible and optimizes anticancer effects for each individual.
