Tumors with high PTBP1 didn’t have fewer immune cells — instead, their T cells were more dysfunctional/exhausted, explaining the poor response to immunotherapy.

This suggests PTBP1 impacts immune function qualitatively (e.g., antigen presentation, T cell state) rather than simply reducing immune cell numbers.

Patients with high PTBP1 expression ❌ did not respond to immunotherapy and showed shorter progression-free and overall survival.

Interestingly, when PTBP1 was removed, the cells reactivated HLA expression — proteins essential for immune cells to recognize and attack tumor cells.

But why do some respond while others don’t?
We set out to identify genes linked to immune evasion in TNBC — and that’s how we found PTBP1.
