Our results showed, reduction in MMP-2 (p=0.08), MMP-9 (p=0.03), CCL22 (p=0.003) and TGFβ1 (p=0.1) gene expression and Tregs frequency (p=0.01) which play a main role in the development of chronic inflammation, angiogenesis, tumorigenesis and metastasis.
Manipulation of CCL22 expression in cancer cells altered tumorigenesis in both immune-compromised and -competent mice, supporting both autonomous and non-autonomous actions of CCL22.
Circulating levels of macrophage-derived chemokine (CCL22), a chemokine previously implicated in lung carcinogenesis, were reduced among hog farmers (17% decrease; 95% CI -28% to -4%), in particular for those with the largest operations (>6000 hogs: 26% decrease; 95% CI -39% to -10%; p<sub>trend</sub>=0.002).
