conducted many of the fatty acid analyses, including growing and harvesting plants, preparing fatty acid methyl esters and analyzing some of those fatty acid methyl esters on a gas chromatograph.
They are absorbed through the skin and prolonged exposure can cause blurry vision (dibasic esters are metabolized to formic acid).
The discovery of novel "non-kinase" phorbol ester receptors challenges the use of phorbol esters as selective PKC activators [ 24 ] . Therefore, we were interested in whether a member of the PKC family mediated the effect of PMA in LS1034 cells or whether some other proteins could also be involved.
These polymers belong to several classes: (1) sulfate esters of polysaccharides (dextrin and dextran sulfates [ 1 2 3 4 5 6 7 8 9 10 11 ] ; cellulose sulfate [ 12 13 14 15 ] ; sulfate esters of galactose + 3,6-anhydrogalactose copolymers {carrageenan; [ 1 16 17 18 19 ] }); (2) polymers containing sulfonated benzene or naphthalene rings {poly(styrene-4-sulfonate) [ 20 21 ] } and naphthalene sulfonate polymers {PRO2000 [ 22 23 24 ] }; and (3) polycarboxylates (acrylic acid polymers {Carbomer 974P; BufferGel [ 25 26 27 28 29 ] }); and acetyl phthaloyl cellulose {cellulose acetate phthalate (CAP) [ 30 31 32 33 34 35 36 37 ] }.
It is known that during clonal selection in the thymus, immature CD4, CD8 double positive cells develop into single positive CD4 or CD8 cells according to the relative affinity of their TCR to class II or class I molecules respectively [ 5 6 ] . These immature T-cells are selected in the thymic epithelium on the basis of their TCR interaction with either class I or class II MHC molecules [ 7 8 ] , thus generating two mutually exclusive subpopulations that are characterized by the expression of either CD4 or CD8 glycoproteins [ 9 ] . Earlier studies in the murine system have demonstrated that PMA and cAMP can modulate the expression CD4 and CD8 on developing thymocytes [ 10 11 12 13 ] . In keeping with these findings, ex vivo experiments with human thymocytes previously reported by our group, revealed that while phorbol esters can coordinately regulate the transcription of α and β TCR during intrathymic T cell differentiation [ 14 ] , cAMP selectively affected the transcription of the α and δ-TCR [ 15 16 ] . Together the murine data and our own findings support the hypothesis that in humans, TCR expression and CD4, CD8 commitment and selection may be regulated by the same signal-transduction pathways.
