Pre-existing cytotoxic capacity of CD8+and CD4+T cells is a hallmark of richter transformation and favors response to anti-PD-1 therapy
Övrigt konferensbidrag, 2025

Immune checkpoint blockade (ICB) therapy has shown promising activity in Richter Transformation (RT), yet the tumor microenvironmental (TME) determinants of response and resistance to this therapy remain incompletely defined. Our previous single-cell RNA sequencing (scRNA-seq)-based analysis of splenocytes from CLL and RT mouse models identified enrichment in CD8+ effector/exhausted and CD4+ cytotoxic T cells, together with CXCL9/10+ pro-inflammatory macrophages, as a characteristic of most RT cases. The deeper characterization and the functional activities of these candidate cell populations, however, have not yet been elucidated.
