Researchers at WashU Medicine identified a direct connection between cancer-related inflammation and the loss of motivation characteristic of advanced cancer. In a mouse study they describe a brain pathway that starts with neurons (labeled in green, above) that sense inflammation signals, and the researchers were able to treat the loss of motivation by blocking this pathway.

CD8 T cell priming occurs in two phases. In the activation phase (day 1), naïve T cells engage with dendritic cells (DC) for 24 hours, then detach, proliferate, and move deeper into the lymph node. In the selection phase (days 2-3), activated T cells regain sensitivity, re-engage with antigen-presenting cells, and receive IL-2 support from CD4 T cells. Regulatory T cells limit IL-2 availability, driving the expansion and differentiation of high-affinity CD8 T cells into effector cells.
