"Couple's Immunotherapy": Is CXCL13 at the Heart of the Prescription?

Sex differences in cancer survivorship and response to immunotherapy have been observed, with males generally displaying better outcomes to immune checkpoint blockade compared with females.

See related article by Brennan et al., p. 956 (3).
