The human CYP2A6 enzyme metabolizes certain drugs and pre-carcinogens and appears to be the most important enzyme for nicotine metabolism. At present, more than 10 different allelic variants are known that cause abolished or decreased enzyme activity. Genetic polymorphism in this gene might be of particular importance for an individual's need for nicotine(More)
Neisseria gonorrhoeae is a human pathogen causing the sexually transmitted disease gonorrhoeae. The bacteria preferentially attach to and invade epithelial cells of the genital tract. As these cells previously have been shown to express the human cathelicidin LL-37, we wanted to investigate the role of LL-37 during N. gonorrhoeae infection. The cervical(More)
The persistent environmental pollutant 3-methylsulfonyl-DDE (3-MeSO2-DDE) undergoes bioactivation by cytochrome P450 11B1 (CYP11B1) in the adrenal cortex of several animal species in vivo and causes decreased glucocorticoid production and cell death in the zona fasciculata. This study presents extended investigations of the cytotoxic and endocrine(More)
The environmental pollutant 3-MeSO2–DDE [2-(3-methylsulfonyl-4-chlorophenyl)-2-(4-chlorophenyl)-1,1-dichloroethene] is an adrenocortical toxicant in mice, specifically in the glucocorticoid-producing zona fasciculata, due to a cytochrome P450 11B1 (CYP11B1)-catalysed bioactivation and formation of covalently bound protein adducts. o,p′-DDD(More)
The DDT metabolite 3-methylsulfonyl-DDE (3-MeSO(2)-DDE) has been proposed as a lead compound for an improved adrenocortical carcinoma (ACC) treatment. ACC is a rare malignant disorder with poor prognosis, and the current pharmacological therapy o,p'-DDD (mitotane) has limited efficacy and causes severe adverse effects. 3-MeSO(2)-DDE is bioactivated by(More)
Pili of Neisseria gonorrhoeae are phase-variable surface structures that mediate adherence to host target cells. Each pilus is composed of thousands of major pilus subunits, pilins, pilus-associated protein PilC, and possibly other components. Piliated and nonpiliated gonococcal clones may secrete a soluble smaller pilin (S-pilin) that is cleaved after(More)
Neisseria meningitidis and Neisseria gonorrhoeae colonize human mucosal surfaces and cause sepsis/meningitis and gonorrhoea respectively. The first step in the infection process is pilus-mediated adhesion of the bacteria to epithelial cells, followed by host cell invasion. Adhesion of pathogenic Neisseria elicits multiple responses in host cells, including(More)
