OBJECTIVE: The present investigation compared the ability of the skin allergens oxazolone and 2,4-dinitrochlorobenzene (DNCB) and the skin irritant benzalkonium chloride (BZC) to stimulate the cutaneous expression of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) in mice.

Secretions of PGE2, IL-1alpha, and IL-6 at x10 dilutions of latanoprost or timolol were 3 to 77 times higher than in controls, whereas they were 190 to 305 times higher at a x180 dilution of benzalkonium chloride.

The present study evaluates four surface-active microbicide candidates, nonoxynol-9 (N-9), benzalkonium chloride (BZK), sodium dodecyl sulfate, and sodium monolaurate for their activity against human sperm and HIV, and their capacity to induce an inflammatory response on human vaginal epithelial cells and by the rabbit vaginal mucosa.

In the present study we have addressed this by examination of the local cutaneous production of interleukin 6 (IL-6) following topical exposure of mice to oxazolone, a potent contact allergen, or to benzalkonium chloride (BZC), a skin irritant that is considered not to have a significant potential to cause skin sensitization.

A significantly higher BALF concentration of IL-6 and IgE was noted in animals exposed to single and repeated doses.

In spite of the augmented CD86 expression on DC treated with DNCB or NiCl2, these chemicals induced different responses of DC in their expression of CD54 and HLA-DR and the production of IL-6 and tumor necrosis factor (TNF)-alpha.
After we confirmed that monocyte-derived DC showed at least phenotypic characteristics and a response to TNF-alpha similar to LC, we added various chemicals, i.e., dinitrochlorobenzene (DNCB), trinitrochlorobenzene (TNCB), NiCl2, ZnCl2, sodium dodecyl sulfate (SDS), or benzalkonium chloride (BC), to a culture of purified monocyte-derived CD1a+ DC.

In evaluating this system for irritancy testing, three different measures of toxicity were used: MTT (dimethylthiazol diphenyltetrazolium bromide) reduction, and lactate dehydrogenase and interleukin-6 release.
The experiments described herein represent a preliminary evaluation to determine the usefulness and predictive value of our 24 ED kit as an alternative method for the prediction of human dermal reaction, versus three chemical products: cadmium chloride, lauryl sulfate, and benzalkonium chloride.

At various times after gel application, cell differentials and levels of inflammatory cytokines (IL-1beta, IL-4, IL-6, IL-8, IL-10, IL-18, IFN-gamma, and TNF-alpha) in cervicovaginal lavage (CVL) fluid were monitored by flow cytometry and ELISA, respectively.

In response to exogenous stimuli such as phorbol-12-myristate 13-acetate, ultraviolet B radiation, and lipopolysaccharide, human keratinocytes produce soluble mediators that are important in primary contact irritancy including cytokines that are associated with proinflammatory properties (interleukin-1 alpha [IL-1 alpha], tumor necrosis factor alpha), chemotaxis (IL-8), and growth activation (granulocyte/macrophage colony stimulating factor, IL-6, transforming growth factor alpha).
We examined qualitative and quantitative changes in selected intracellular and secreted cytokines in human keratinocyte cultures in response to non-sensitizing contact irritants (croton oil, sodium lauryl sulfate, methyl salicylate, ethyl phenylpropiolate), sensitizing irritants (oxazolone, dinitrofluorobenzene), and ulcerative agents (phenol, benzalkonium chloride, chromium trioxide).

Concentrations for interleukin (IL)-6 in the placebo period were 41.5 pg/mL (0.9-91.7 pg/mL) and in the BAC period were 17.6 pg/mL (3.2-65.9 pg/mL; p = 0.46), and concentrations for substance P were 119 pg/mL (58-293 pg/mL) and 131 pg/mL (80-330 pg/mL; p = 0.31), respectively.

Twice daily and for four and a half days, confluent secondary (2-4 passages) cultures were treated (30 minutes at 37 degrees C) with the following drugs (diluted at 1:400-1:100): 0.2% brimonidine-tartrate (Alphagan), 2.0% dorzolamide-HCl (Trusopt), 0.5% timolol-maleate (Timoptic), 2.0% dorzolamide-HCl/0.5% timolol-maleate (Cosopt), 2 and 4% pilocarpine-HCl (Akarpine and Pilocar), 0.005% latanoprost (Xalatan), placebos for Trusopt and Timoptic, and 0.01% benzalkonium chloride.

Graefes Arch Clin Exp Ophthalmol. 2007 Apr;245(4):534-46. Epub 2006 Aug 10.

Supernatants of histamine-stimulated cells were evaluated for the production of IL-6 and IL-8 by ELISA, while the expression of ICAM-1 was evaluated by flow cytometry on IFN gamma-stimulated cells.
Conversely, eye drops preserved with benzalkonium chloride (BAC) induced even higher ICAM-1 expression levels on IFN gamma-stimulated cells than did IFN gamma alone, whereas unpreserved drugs had no effect.
