flag A new study finds tumors disable immune T cells via CD47-thrombospondin-1 interaction, and blocking it boosts cancer treatment effectiveness.

flag A new study published in Nature Immunology reveals that tumors suppress immune T cells by exploiting a CD47-thrombospondin-1 interaction, driving T cell exhaustion and weakening anti-cancer responses. flag Researchers found that exhausted T cells in human and mouse tumors overexpress CD47, which binds to thrombospondin-1 produced by cancer cells, further inhibiting immune function. flag Blocking this interaction with a peptide called TAX2 restored T cell activity, slowed tumor growth in melanoma and colorectal cancer models, and enhanced the effectiveness of PD-1 checkpoint inhibitors. flag The findings suggest a promising new strategy to improve immunotherapy outcomes by targeting this pathway.
