1,2,3,4,7,8,9-Heptachlorodibenzofuran  (Synonyms: 1,2,3,4,7,8,9-HpCDF)

1,2,3,4,7,8,9-Heptachlorodibenzofuran (1,2,3,4,7,8,9-HpCDF) is a compound that induces the expression of CYP1A1 and CYP1B1 genes in human peripheral blood lymphocytes, while also promoting the expression of the aryl hydrocarbon receptor repressor (AhRR). 1,2,3,4,7,8,9-Heptachlorodibenzofuran can increase ethoxyresorufin-O-deethylase (EROD) activity in isolated human peripheral blood lymphocytes in a concentration-dependent manner, which serves as a marker of CYP1A1 activity. Furthermore, 1,2,3,4,7,8,9-Heptachlorodibenzofuran exhibits immunosuppressive effects by reducing the number of splenic plaque-forming cells in mice and increasing aryl hydrocarbon hydroxylase (AHH) activity in liver microsomes of mice injected with sheep red blood cells. 1,2,3,4,7,8,9-Heptachlorodibenzofuran can be used in research in the fields of immunology, metabolic diseases, and environmental toxicology^[1][2][3][4].
