Key features of NeoDisc include:

1. Detection of various tumor-specific antigens, including neoantigens and other aberrantly expressed proteins
2. Application of machine learning and rule-based algorithms to prioritize antigens likely to elicit T cell responses
3. Generation of visualizations depicting cancer cell heterogeneity within tumors
4. Identification of potential defects in antigen presentation machinery

Advancing Personalized Immunotherapy

The development of NeoDisc addresses several challenges in cancer immunotherapy:

1. Patient variability in response to treatments due to neoantigen diversity
2. Technical difficulties in identifying effective neoantigens recognized by T cells
3. Integration of multiple analytical technologies, including immunopeptidomics, genomics, and transcriptomics

Dr. Michal Bassani-Sternberg, a pioneer in the field of immunopeptidomics, emphasized that NeoDisc is already being used in clinical trials for personalized cancer vaccines and adoptive cell therapies at the Lausanne Branch of the Ludwig Institute for Cancer Research 1
