1. ENTER #mRNAvaccines for #pancreaticcancer! Long-term #PDAC survivor story PART3.
"Do #PDACs REALLY have vaccine neoantigens (NAs)"? (aren’t they lowly mutated?)
If each patient = own NAs, how do you vaccinate?
Maybe mRNA? But how?

2. In 2017, we reported in @Nature here -> nature.com/articles/natur… -> that primary tumors of long-term survivors of #PDAC had ~12x more activated CD8 T cells vs. short-term survivors
AND
despite #PDAC’s few mutations, mutation-derived NAs may still be T cell antigens in #PDAC.

3. Now, prevailing belief ->#PDAC = few mutations = fewer mutation-derived NAs = NAs unlikely #PDAC T cell antigens.
BUT...our #NeoantigenQualityModel(estimates the ~1-2% of immunogenic NAs)
found that long term #PDACsurvivors ∝ more “high quality” NAs ∝longer survival.
