摘要: Alterations in phosphorylation of cellular proteins are a hallmark malignant transformation. Degradation these phosphoproteins could generate cancer-specific class I MHC-associated phosphopeptides recognizable by CD8+ T lymphocytes. In comparative analysis presented on the surface melanoma, ovarian carcinoma, and B lymphoblastoid cells, we find 5 36 that restricted to solid tumors common both cancers. Differential presentation peptides can result from differential source proteins. Recognition cancer cells phosphopeptide-specific lymphocytes validates potential as immunotherapeutic targets.
