Arrangement of cytokines and relevant transcription factors in the human genome. Certain genes are grouped in several genomic loci positioned on chromosome 2 (IL1α, IL1β, and their receptor), 4 (CXCL 1, 2, and 10), and 17 (CCL2-7). Transcription factors STAT1 and NFκB have been mapped to chromosome 3 (STAT1) and 4 in the proximity to the CXCL cytokine gene family (NFκB). The IRF transcription factors do not form a single group and are distributed between different chromosomes. Other cytokines and their receptors highlighted in the review also do not show any spatial correlations.
