MIG (CXCL9) is another chemokine that is considered to play a role in the interplay between neurons and glial cells, and binds onto the CXCR3 receptor which has been previously reported to be involved in the pathogenesis of various CNS conditions (e.g. multiple sclerosis, glioma, bipolar disorder) (Koper et al., 2018, Zhou et al., 2019). The gene discussed is CXCL9; the disease is bipolar disorder.
