In addition, MAP3K8, FAS, IL12RB2, and IL 26, have been identified to play role in Th1 polarized cells. Moreover, Table 2 and Additional file 2, Table S1 contain numerous diffe rentially regulated transcripts which are only poorly cha racterized or their role in CD4 Th cells has not been studied. The novel Th1 specific compound libraries genes DMD and PALLD, encoding cytoskeletal associated proteins dystrophin and palladin, fall into the reciprocally regulated genes in the Th subsets studied here. Also, Th1 specific putative pseudogene NAPSB and non coding transcript MIAT show reciprocal transcript profiles. Other novel genes in clude PRR5L, which has been identified to interact with a highly conserved protein kinase TOR, a central controller of cell growth and apoptosis.

OSBPL10 encodes oxysterol binding protein like 10, an intracellular lipid receptor that regulates cellular lipid Inhibitors,Modulators,Libraries metabolism. P2RY14 is a membrane receptor for UDP glucose and plays a role in immune responses Inhibitors,Modulators,Libraries in human airway as well as female reproductive track epithelial cells by stimulating cytokine and chemokine production Inhibitors,Modulators,Libraries and recruitment of neutrophils. P2RY14 has also been identified to function in mouse splenic T cells as a regula tor of IL 2 induced proliferation, however, no specific link to Th1 cells has been observed. Also, the significance of ATP9A, LPAR3 functioning in G protein cou pled receptor signaling, XRN1, BSPRY, MCTP2 or PTPRO in Th1 cells is yet to be studied. Recent data indicate that in B cells, PTPRO dephosphorylates Syk, a kinase that is critical in signal transduction of B cell receptor.

The Th2 up regulated genes, PDE7B, SETBP1, C9orf135, TPRG1, IGSF3, or PPP1R14A have not been linked to CD4 Th cell function, although their IL 4 mediated up regulation has been published, and furthermore, SETBP1, TPRG1 and PPP1R14A have been identified as direct targets of STAT6. Interestingly, we observed that most of the genes whose expression differs between all the three lineages Inhibitors,Modulators,Libraries behave in a similar manner, i. e. they are up regulated in Th1 and down regulated in Th2. Among the reciprocally regulated genes we found 34 genes up regulated in Th1 condition and only six genes behaved in the opposite manner. The hierarchical clus tering of the kinetic profiles is depicted in Figure 5A. This suggests that there are common mechanisms that induce reverse regulatory behavior.

For example, the genes up regulated in Th1 condition might be controlled downstream of IFN��. This hypothesis is supported by the clear similarity between Inhibitors,Modulators,Libraries the profiles of IFN�� and the profiles of the clustered genes. We prepared a similar figure showing the differences in the kinetics of all the LIGAP identified genes. These results are depicted in Figure 5B and they show the similarity between the Th0 and Th1 lineages and their dissimilarity Vandetanib mechanism of action between the Th2 lineage.
