  • Patent number: 9956270
    Abstract: The present invention relates to a pharmaceutical composition for treating or preventing a disease related to abnormal suppression of regulatory T cell activity comprising a polypeptide comprising a bee venom-PLA2 amino acid sequence exclusive of a leader sequence as an active ingredient. The secretory bee venom-phospholipase A2 of the present invention activates a regulatory T cell and suppress a differentiation of Th1/Th7. Therefore, the present polypeptide can be used as a pharmaceutical composition for treating or preventing a disease related to abnormal suppression of regulatory T cell activity, i.e. autoimmune diseases, allergic diseases, or neurodegenerative diseases.

    Abstract: A web control system for solar tracking includes one or more trackers, a communication port management unit, a status processing unit, a tracker control unit, a back tracking unit, a web server unit, and the memory unit. The trackers operate in compliance with driving commands and change the position of a solar cell panel in response to the tracking of the location of a sun. The communication port management unit is responsible for data transmission and reception. The status processing unit scans the status of the trackers. The tracker control unit directly controls the trackers. The back tracking unit analyzes the status information, and controls the tracker control unit. The local GUI interface unit displays a local or remote user screen. The web server unit provides the GUI data to a user. The memory unit stores the information.
