Summary

Story summary

Massachusetts Institute of Technology researchers developed a method to stimulate cancer cells to produce cGAMP, activating STING pathway and boosting tumor destruction in mice.
They combined mRNA delivery with checkpoint inhibitors, controlling tumor growth.
A study from Weill Cornell Medicine shows tumors drive T cell exhaustion through the CD47-TSP-1 axis and inhibiting it restores T cell function.
Together, the studies highlight immunotherapy strategies to achieve safer, more effective cancer treatments.
