WebThe Human Cell Line Activation Test (h-CLAT) is a cell-based assay that identifies skin sensitizers by examining changes in the expression of cell surface markers (CD54 and CD86) implicated in dendritic cell activation, the third key event of the skin sensitization adverse outcome pathway. Following exposure of the THP-1 human monocyte cell line … WebIn the last decade, incredible progress has been made in the development of a nonanimal test to assess contact hypersensitivity. In vitro methods, such as the myeloid U937 skin sensitization test, hCLAT, and THP-1 activation assay, may be used in the preclinical phase of drug development for hazard identification of the potential to induce DTH.
