Characterising the HLA-I immunopeptidome of plasma-derived extracellular vesicles in patients with melanoma.

Extracellular vesicles (EVs) frequently express human leukocyte antigen class I (HLA-I) molecules. The immunopeptidomes presented on EV HLA-I are being mapped to provide key information on both specific cancer-related peptides, and for larger immunopeptidomic signatures associated with disease. Utilizing HLA-I immunoisolation and mass spectrometry, we characterised the HLA-I immunopeptidome of EVs derived from the melanoma cancer cell line, ESTDAB-026, and the plasma of 12 patients diagnosed with advanced stage melanoma, alongside 11 healthy controls.

Excellence in Organ Utilisation-A Quantitative and Qualitative Evidence Base for a New Approach in the UK.

The Department of Health and Social Care in England established an Organ Utilisation Group, to collate and analyse evidence regarding the organ transplantation care pathway, make recommendations on how to reduce inequity of access, make the best use of available resources, and drive innovation in organ transplantation. The group consulted with national and international experts and stakeholders, sought views from service providers across the transplant care pathway, and heard from over 600 people, including over 250 patients, carers, and donors. The group uncovered new evidence about where improvements are needed-particularly in relation to patient experience and inequities in access.
