Genomic instability can induce an anti-tumour immune response via activation of the cGAS-STING pathway following the formation of micronuclei (MN). Here, the authors identify a role for DNAJA2 in maintenance of chromosomal segregation. Loss of which increased MN formation and cGAS-STING pathway activation, increasing response to immune checkpoint blockade.
