Abstract CRH is widely expressed in the brain and is of broad functional relevance to a number of physiological processes, including stress response, parturition, immune response, and ingestive behavior. To delineate further the organization of the central CRH network, we generated mice expressing green fluorescent protein (GFP) under the control of the CRH promoter, using bacterial artificial chromosome technology. Here we validate CRH-GFP transgene expression within specific brain regions and confirm the distribution of central GFP-producing cells to faithfully recapitulate that of CRH-expressing cells. Furthermore, we confirm the functional integrity of a population of GFP-producing cells by demonstrating their apposite responsiveness to nutritional status. We anticipate that this transgenic model will lend itself as a highly tractable tool for the investigation of CRH expression and function in discrete brain regions.

Background: The interaction of phospholamban (PLB) and the sarcoplasmic reticulum Ca2+-ATPase (Serca2a) is a key regulator of cardiac contractility and a therapeutic target in heart failure (HF). PLB mediated increases in Serca2a activity improve cardiac function and HF. Clinically this mechanism can only be exploited by a general activation of the proteinkinase A (PKA) which is associated with side effects and adverse clinical outcomes. A selective interference of the PLB-Serca2a interaction is desirable but will require novel tools that allow for an integrated assessment of this interaction under both physiological and pathophysiological conditions. Methods: A circularly permutated green fluorescent protein (cpGFP) was interposed between Serca2a and PLB to result into a single Serca2a-cpGFP-PLB recombinant protein (SGP). Expression, phosphorylation, fluorescence and function of SGP were evaluated. Results: Expression of SGP-cDNA results in a functional recombinant protein at the predicted molecular weight. The PLB domain of SGP retains its ability to polymerize and can be phosphorylated by PKA activation. This increases the fluorescent yield of SGP by between 10% to 165% depending on cell line and conditions. Summary: A single recombinant fusion protein that combines Serca2a, a circularly permutated green fluorescent protein and PLB can be expressed in cells and can be phosphorylated at the PLB domain which markedly increases the fluorescence yield. SGP is a novel cellular Serca2a-PLB interaction monitor.

Abstract Tunneling Nanotube (TNT) , a dynamic cell-cell contact, is dependent on actin polimerization. TNTs are efficient in transporting ions, proteins and organelles intercellularly, which are important mechanisms in physiological and phathological precesses. Reported studies on the existence and function of TNTs among neural cells focus on cultured cell for the convenience in detecting TNTs’ ultrastructure. In this study, the adeno-associated virus (AAV-GFAP-EGFP-p2A-cre) was injected in the cerebral cortex of knock-in mice ROSA26 GNZ. GFAP promoter initiated the expression of Enhanced Green Fluorescent Protein (EGFP) in infected astrocytes. At 10 days post injection (10 DPI), we found that EGFP could transfer from astrocytes in layerⅠ-Ⅲ to neurons in layer Ⅴ. The dissemination of EGFP was not through endocytosis or exosome. And the intercellular transportation of EGFP was F-actin dependent. Therefore, we concluded EGFP transported from astrocytes to neurons in coetex via F-actin dependent TNTs. Although it is hardly to detect the ultrastrucute of TNTs in brain for its transiency and the noisy background, we established an animal model and indirect experimental methods to explore TNTs in vivo.
