Many Caenorhabditis elegans genes exist in operons in which polycistronic precursors are processed by cleavage at the 3' ends of upstream genes and trans splicing 100 to 400 nucleotides away, at the 5' ends of downstream genes, to generate monocistronic messages. Of the two spliced leaders, SL1 is trans spliced to the 5' ends of upstream genes, whereas SL2(More)
CD40 ligand (CD40L, CD154) is a membrane protein that is important for the activation of dendritic cells (DCs) and DC-induced CD8(+) T cell responses. To be active, CD40L must cluster CD40 receptors on responding cells. To produce a soluble form of CD40L that clusters CD40 receptors necessitates the use of a multitrimer construct. With this in mind, a(More)
Humans are exposed to various chemical mixtures daily. The toxic response to a mixture of chemicals could be potentiated or suppressed. This study demonstrates that non-toxic doses of pesticides can induce cellular changes that increase cell sensitivity to other toxins or stress. Pesticide exposure is an environmental risk factor for Parkinson’s disease.(More)
