G-protein coupled receptors (GPCRs) are the most abundant class of proteins in the cell body. Such receptors are of major interest as potential therapeutic targets. Downscaling and parallelization of bioanalytics opens novel routes to rapidly screen and id ...
The sympathetic nervous system (SNS) is able to modulate immune functions via adrenoceptor-dependent mechanisms. Activation of β₂-adrenergic receptors (AR) on CD4(+) T lymphocytes has been shown to inhibit Th1-cytokine production and cell proliferation. He ...
Transforming Growth Factor beta (TGFβ) signaling plays an important role in a variety of cellular processes during embryonic development, adult tissue homeostasis and cancer. TGFβI ligand is a potent inhibitor of early hematopoietic progenitor [1] cells in ...
The TNF family ligand B cell-activating factor (BAFF, BLyS, TALL-1) is an essential factor for B cell development. BAFF binds to three receptors, BAFF-R, transmembrane activator and CAML interactor (TACI), and B cell maturation antigen (BCMA), but only BAF ...
IgE induction by parasites and allergens is antigen driven and cognate T cell help dependent. We demonstrate that spontaneously produced IgE in T cell-deficient and germ-free wild-type (wt) mice is composed of natural specificities and induced by a mechani ...
Intrathymic T-cell maturation critically depends on the selective expansion of thymocytes expressing a functionally rearranged T-cell receptor (TCR) beta chain. In addition, TCR-independent signals also contribute to normal T-cell development. It is unclea ...
Thymic T cell lineage commitment is dependent on Notch1 (N1) receptor-mediated signaling. Although the physiological ligands that interact with N1 expressed on thymic precursors are currently unknown, in vitro culture systems point to Delta-like 1 (DL1) an ...
The evolutionarily conserved Notch signalling pathway controls a broad spectrum of cell fate decisions in organisms as diverse as fruit flies and mice. Whithin the murine haematopoietic system, Notch1 is indispensable for T cell development as conditional ...
Notch1 signaling is required for T cell development and has been implicated in fate decisions in the thymus. We showed that Notch1 deletion in progenitor T cells (pro-T cells) revealed their latent developmental potential toward becoming conventional and p ...
It is well established that Notch signaling plays a critical role at multiple stages of T cell development and activation. However, detailed analysis of the cellular and molecular events associated with Notch signaling in T cells is hampered by the lack of ...
