CD47 and neoplasm: In order to prevent APC phagocytosis, tumours can also suppress “eat me” signals like CRT and HMGB1, and upregulate “don’t eat me” signals like CD47, CD24, etc. When TNBC is present, the glycosylation of B7-H4 stabilises and stops this protein from degrading, which suppresses eIF2α phosphorylation (85).
