..Importantly, these insights into TSLP's multifaceted role could potentially allow for novel therapeutic manipulations of these disorders...

..Importantly, these insights into the multifaceted roles of TSLP could potentially allow for novel, therapeutic manipulations of these disorders...

..This example is offered as a cautionary account for other researchers who contemplate using this technology...

..This finding suggests a new role for FOXP3 in human CD4+ T cells: down-modulating responses to TCR-mediated stimulation...

..2008) show that adaptive T regulatory cells control airway inflammation and that it is when they are generated that determines whether they function during acute or chronic inflammation...

..Therefore, it is the balance between FOXP3 and RORgammat function that determines CD4 T cell fate and the type of immune response that will be generated...

..A finding that has implications on both how autoimmunity is regulated in vivo as well an impact on the development of therapeutic interventions for the treatment of autoimmunity...

..This review will discuss this work and place TSLP in the inflammatory cascade that leads to allergic disease...

....

..These findings suggest that TSLP is an important factor necessary and sufficient for the initiation of allergic airway inflammation...

....

..Taken as a whole, these data demonstrate that inhibition of IL-1beta-dependent genes by active retinoid X receptors involves antagonism of NF-kappaB signaling...

..These results help define the events leading to diabetes in DORmO mice and provide new insights into the cellular interactions required for disease development in an Ag-specific model of T1D...

....

..Our data demonstrate that TSLP-mediated Stat5 activation is insufficient for cell proliferation and identifies residues within the TSLP receptor complex required to mediate these downstream events...

..These data suggest that treatment with imatinib may be a novel therapeutic approach for cryoglobulinemia and MPGN in humans...

..Overall, these findings show that overexpression of scurfin reduces T cell responses in vivo such that CD4(+) T cells cannot provide help to B cells during a T cell-dependent Ab response...

..These data also raise the possibility that a failure to generate peripheral TR cells properly may contribute to autoimmune disease and suggest a possible therapeutic role for FoxP3 in the treatment of such diseases...

..Second, we review recent data concerning the molecular mechanism of FoxP3 function and its role in human disease. Finally, we consider what is known about FoxP3 target genes and their effect on T cell physiology...

..Concomitant with differentiation is a loss of FoxP3 mRNA and protein. These data demonstrate that FoxP3 levels regulate T cell function, and that FoxP3 itself is dynamically regulated during effector T cell differentiation...

..These transgenic mice demonstrate that TSLP can initiate a cascade of allergic inflammation in the skin and provide a valuable animal model for future study of this common disease...

....

..Regulation via down-modulation of antigen-presenting cell function, a form of cell-to-cell licensing for suppression, also offers possibilities for the application of peptide-MHC therapeutics...

..This review will focus on the role of FOXP3 in regulating CD4 T cell function in both humans and mice, with an emphasis on recent work in human systems...

..This study provides new insight into the unique features of the asthma pathology contributed by the innate and adaptive immune responses in response to TSLP stimulation...

..Taken together, these results demonstrate that the inflammatory mediators IL-1beta and TNF-alpha regulate human TSLP gene expression in an NFkappaB-dependent manner...

..TSLP-induced responses were significantly, but not completely reduced in IL-4- and IL-13-deficient mice. These results shed light on the pathways and cell types involved in TSLP-induced inflammation...

..This review focuses on Foxp3 expression and function and highlights differences between humans and mice regarding Foxp3 regulation...

..Furthermore, we demonstrate that IPEX mutations in these domains correlate with deficiencies in FOXP3 repressor function, corroborating their in vivo relevance...

..These data expand the possible targets of FOXP3-mediated repression and demonstrate functional differences between FOXP3 isoforms...

..Cells retaining aspects of Treg differentiation persist in the absence of Foxp3, which is suggestive of a Foxp3-independent aspect of Treg biology...

..Expression of a Foxp3 transgene restored Treg and protected against the onset of autoimmunity. Thus, a signal mediated by IL-2Rbeta is essential for the development and homeostasis of Foxp3(+) Treg in vivo...

..Future studies will evaluate the effects of therapies known to influence Treg cell function and FOXP3 expression, including TCR peptide vaccination and supplemental estrogen...

..We review recent progress on how TSLP expressed within thymus and peripheral lymphoid and nonlymphoid tissues regulates DC-mediated central tolerance, peripheral T cell homeostasis, and inflammatory Th2 responses...

..Therefore, the decision of antigen-stimulated cells to differentiate into either T(H)17 or T(reg) cells depends on the cytokine-regulated balance of RORgammat and Foxp3...

..In summary, our data suggest E2 promotes tolerance by expanding the regulatory T cell compartment...

..These in vitro data suggest that CD25(+)CD4(+) T reg cells may contribute to the diminution of HIV-specific T cell immune responses in vivo in the early stages of HIV disease...

..Thus by switching transcriptional partners, NFAT converts the acute T cell activation program into the suppressor program of Tregs...

..In this way FoxP3 expression can be manipulated under conditions designed to assess TR cell function. The experiments will also begin to test the feasibility of manipulating FoxP3 expression as a means of treating autoimmune disease. ..

..The data generated by these experiments will allow for a determination of the role of TSLP in airway inflammation, and will provide the model systems to test the therapeutic efficacy of TSLP interdiction. ..

..The data generated by these experiments will allow for a determination of the role of TSLP in airway inflammation, and will provide the model systems to test the therapeutic efficacy of TSLP interdiction. ..

..This in turn will help guide efforts to develop new interventions for these and other skin inflammatory diseases that directly or indirectly target TSLP. ..

..These analyses will shed light on the regulatory pathways involved in the development of autoimmune disease, and will serve as a model for human immune-system abnormalities. ..

..Finally, there is a need for an instrument capable of doing DNA content and Ca2+- flux analyses. The instrument requested will provide for the current, as well as future, needs of the user group...

..Knowing this information will allow a detailed analysis of the role of CD69 in the initiation and propagation of autoimmune disease to be initiated. ..

..These studies should establish connections between IL-2 signaling and the control of cell cycle and will further understanding of the molecular regulation of T cell expansion during normal and pathological processes. ..

..These analyses will shed light on the regulatory pathways involved in the development of autoimmune disease, and will serve as a model for human immune-system abnormalities. ..

..The experiments will also begin to test the feasibility of manipulating FoxP3 expression as a means of treating autoimmune disease. ..
