In mice, restoring a thymus hormone calmed inflamed immune cells and improved cancer treatment in old age.
Hisashi Kanemaru, Steven Luong et al., Thymulin restrains age-associated myeloid inflammation and enhances cancer immunotherapy, Nature Communications.
A hormone from the thymus gland called thymulin drops as people and mice get older. This drop lets certain immune cells become more inflamed. Inflamed immune cells help tumors grow and resist treatment. In mice, giving back thymulin calmed these cells, boosted tumor fighting cells, and made cancer immune therapy work better in older animals.
This describes a lab finding in aged mice, not a treatment tested in people.
Mice and lab cells only, no human trial yet.
