[Effects of drugs known to trigger psoriasis on HaCaT keratinocytes].

To investigate whether lithium carbonate, propranolol or chloroquine aggravate psoriasis through influencing cytokines of the psoriatic cytokine network, HaCaT keratinocytes were stimulated with TNF-a after treatment with these drugs. Protein secretion of a set of multiple different cytokines and growth factors in culture supernatants were measured by using a cytokine antibody array technology. Expression of IL-8 and IL-6 mRNA was determined by...
