Co-option of retrotransposons promotes antibody diversification
A longstanding mystery in antibody diversification is how AID specifically targets immunoglobulin V genes. Ancient LINE-1 retrotransposons embedded within the immunoglobulin locus provide a recruitment platform for the HUSH complex and AID to drive somatic hypermutation.

This week, that idea reached patients: Viral-mimicry priming + anti-PD-1 in relapsed/refractory NK/T-cell lymphoma delivered 47.6% complete responses, 66.7% ORR, and ~50% 2-year OS, even after prior PD-1 failure (Huang, Cancer Discovery 2025).

Ten years ago, we discovered that reactivating transposable elements triggers an antiviral state in cancer cells, a process we named viral mimicry, unmasking tumors to the immune system (Roulois, Cell 2015).
