In response to antigen presentation, helper T lymphocytes (TH cells) initiate store-operated Ca2+ entry (SOCE) and differentiate into effector subtypes such as TH1 and TH2 cells. These cells play essential roles in adaptive immunity and the pathogenesis of various autoimmune and allergic diseases. The differentiation and activity of TH cells are also critically regulated by paracrine and autocrine soluble factors in the cell microenvironment. Previous studies have reported that TH cells produce gamma-aminobutyric acid (GABA) via glutamic acid decarboxylase (GAD) and express A-type GABA receptors (GABAARs), forming an autocrine GABA …

The Ctcf Chromatin Organizer Is Required For Hindlimb Development, Katherine L. Rabicki
Electronic Thesis and Dissertation Repository
Mutations in chromatin organizer CTCF were identified in patients with intellectual disability and skeletal defects. Previous studies demonstrated that depletion of CTCF in murine limb mesenchyme results in apoptosis in the forelimb. The role of CTCF in the hindlimb, however, is unknown. My objective was to investigate effects of CTCF deletion on chondrogenesis and skeletal development in the hindlimb. In vitro wild-type micromass cultures demonstrate that chondrocyte gene expression is delayed in the hindlimb when compared to forelimbs. Embryonic CtcfFl/Fl;Prx1Cre mice were investigated, and qRT-PCR and histology were performed on limb buds and long bones. Results show that …
