B cells play a crucial role in regulating anti-tumour immunity.

A new study has identified a subset of B cells that express a protein called TIM-1 and multiply in response to melanoma tumour growth. Deleting the gene that encodes TIM-1 in these cells unleashed an antitumour immune response, suggesting a potential role for B cells in antitumour immunity.
