In the present study, we analyzed the phenotypic alterations induced by several allergens on immature dendritic cells (DC), with the aim to develop a potential in vitro alternative for predicting the sensitizing potential of chemicals. DC were generated from human monocytes cultured in the presence of GM-CSF, IL-4 and TGF-beta1 and treated for 2 or 4 days with different chemicals. Surface marker expression (HLA-DR, CD1a, CD40, CD54, CD83, CD86, CCR7 and E-cadherin) was analyzed by flow cytometry.

Most tumor cells synthesize and shed large amounts of gangliosides into their microenvironment, and many studies have unraveled their immunosuppressive properties. In the present study we analyzed the effects of GM3 and GD3 gangliosides, purified from human melanoma tumors, on the differentiation of monocyte-derived dendritic cells (MoDC).

Handling genotoxic compounds commonly used in cancer chemotherapy generates contaminated wastes that require decontamination before disposal. Chemical methods are an alternative and/or a complement to incineration for the treatment of wastes and spills. As part of a program initiated by the International Agency for Research on Cancer (IARC), three chemical methods readily available in the hospital environment, viz sodium hypochlorite (NaOCl, 5.

Because of this a precise diagnosis has to be made, and this is done by: biological examination of serum F.S.
