Article Synopsis
- Checkpoint immunotherapy struggles against non-immunogenic tumors like neuroblastoma due to low MHC class I expression and neoantigen burden, but inhibiting ERAP1 can enhance anti-tumor immune responses.
- A novel strategy combining genetic knockout of ERAP1 with the HDAC inhibitor entinostat was developed, leading to increased immunogenicity and making neuroblastoma more responsive to PD-1 therapy.
- Experimental methods included CRISPR/Cas9 gene editing, flow cytometry, and mass spectrometry to demonstrate that ERAP1 inhibition improves immune cell activity and increases MHC class I and PD-L1 expression in neuroblastoma cells, ultimately slowing tumor growth.
Article Synopsis
- Most COVID-19 vaccines focus on the Spike protein, but mutations in the virus highlight the need for broader vaccine development.
- The study uses mass spectrometry to identify immunopeptides from seven stable SARS-CoV-2 proteins, mapping their interactions with various Human Leukocyte Antigens (HLA) worldwide.
- Out of 248 unique peptides found, over half are novel, and testing shows T cell responses to several peptides, which could help create improved COVID vaccines targeting multiple virus proteins.
Fibrolamellar carcinoma (FLC) is a liver tumor with a high mortality burden and few treatment options. A promising therapeutic vulnerability in FLC is its driver mutation, a conserved DNAJB1-PRKACA gene fusion that could be an ideal target neoantigen for immunotherapy. In this study, we aim to define endogenous CD8 T cell responses to this fusion in FLC patients and evaluate fusion-specific T cell receptors (TCRs) for use in cellular immunotherapies.

However, the vision-impaired community is often disadvantaged when the most common audio-visual approach of scientific communication is applied. Here we integrated tactile clues in the scientific communication of immune processes involved in the autoimmune skin disease psoriasis.
