Aplicação

1-Chloro-2,4-dinitrobenzene was used in determination of relative amounts of individual glutathione S-transferases subunits in human tissues by reverse-phase HPLC. It was used as contact sensitizer to study the antibacterial peptides hBD-2, -3 and -4 and LL-37 induced IL-18 protein release in human keratinocytes.

Ações bioquímicas/fisiológicas

2,4-dinitrochlorobenzene induces atopic dermatitis in BALB/c mice model.

Nota de preparo

The product is dissolved in ethanol when used as glutathione S-transferase substrate and then added to a buffer to form a final concentration of 1mM in phosphate buffer (8 mL of 0.2 M KH2PO4 and 28 mL of 0.1 M Na2HPO4 per 100 mL of solution, adjusted to pH 6.5) and 4% (v/v) ethanol.

Bacillus Calmette-Guerin extract (BCGE) has been proven to be clinically effective for anaphylactic disease, infectious diseases and cancer. In this study, we investigated the effect of the intramuscular application of BCGE on 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD). We established an

Uncertainties about the composition and identities of glutathione S-transferases (GSTs) in human tissue have impeded studies on their biological functions. A rigorous protocol has therefore been developed to characterize the human proteins. Cytosolic GST subunits were resolved by reverse-phase HPLC

In addition to its physical barrier against invading microorganisms, the skin produces antimicrobial peptides, human beta-defensins (hBDs) and cathelicidin LL-37, that participate in the innate host defense. Because IL-18 is produced by keratinocytes and involved in skin diseases in which

Several in vitro DNA microarray studies have shown the importance of nuclear factor (erythroid-derived 2)-like 2 (Nrf2) in skin sensitization. Nevertheless, the exact in vivo role of the Nrf2-Keap1 pathway during the induction of skin sensitization remains unknown. To study
