CYP19A1 and infection: We predicted that: (1) the enzymes producing PGE2 would be up-regulated in individuals whose medical records indicate signs of infection or inflammation at or near death, (2) that the enzyme aromatase would also be up-regulated with infection or inflammation, and (3) that expression of enzymes producing PGE2 and receptors signaling for PGE2 would correlate with aromatase expression during inflammation, but would not correlate in expression in individuals not experiencing inflammation.
