Longitudinal single-cell and spatial transcriptomics reveals intratumor heterogeneity, therapeutic response, and comparative value of canine marginal zone lymphoma
This study utilizes longitudinal single-cell and spatial transcriptomics to characterize intratumoral heterogeneity and therapeutic responses in a canine marginal zone lymphoma case, revealing that while oncolytic VSV virotherapy successfully targeted B cells, the resulting cytotoxic immune response was primarily driven by T cells, thereby highlighting the need for improved subtyping and multidimensional treatment strategies.
