Publication number: 20130017226Abstract: The present invention relates to TNFR2-TWEAKR fusion protein, more precisely to TNFR2-TWEAKR fusion protein acting as a double-antagonist to TNF-? and TWEAK, known as major causes of autoimmune arthritis which is one of autoimmune diseases. When the composition comprising TNFR2-TWEAKR fusion protein was treated to Th17 cells, the secretion of the inflammatory cytokine IL-17 was reduced but the secretion of the anti-inflammatory cytokine IL-10 generated in Treg cells was increased. Such effect of TNFR2-TWEAKR fusion protein was far greater than that of a single protein such as TNFR2-Fc or TWEAK-Fc. The TNFR2-TWEAKR fusion protein of the present invention has not only excellent treatment effect on arthritis in CIA mouse model not also excellent treatment effect on autoimmune rheumatoid arthritis by increasing the expression of Treg, the immune suppressive cells.Type: ApplicationFiled: March 18, 2011Publication date: January 17, 2013Applicants: Industry-Academic Cooperation Foundation, The Catholic University of Korea, Korea Research Institute of Bioscience and BiotechnologyInventors: Young Woo Park, Ki Won Jo, Srok Ho Yoo, Jung Yu, Dong Ji Kim, Sun-Ha Yoon, Eun Jung Song, Eun Kyung Lee, Jin Mi Oh, Kyu Won Cho, Mi La Cho, Ho Youn Kim, Mi Kyung Park, Hye Jwa Oh, Jin Sil Park, Yun Ju Woo, Jae Kyeong Byun, Jun Geol Ryu

Patent number: 6131403Abstract: Disclosed is a refrigerator having a cool air dispersing device. A duct housing forming a cool air duct is installed on a rear part of a cooling compartment, and many cool air discharge ports open into the cooling compartment are formed on the duct housing. In the cool air duct are installed many cool air dispersing blades of planar plate shape corresponding to the discharge ports respectively and capable of rotating. The blades control a discharge direction of cool air supplied into the cooling compartment according to a rotational position thereof. The blades have a size similar to the discharge ports, and can close the discharge ports at a predetermined rotational position thereof. While a cooling system is not operating, the discharge ports are closed by the blades, whereby the backflow of air in the cooling compartment toward an evaporator is prevented, and less frost is generated on the evaporator.Type: GrantFiled: September 24, 1998Date of Patent: October 17, 2000Assignee: Samsung Electronics Co., Ltd.Inventor: Joon Dong Ji

Patent number: 6044659Abstract: Disclosed is a refrigerator having a device for opening/closing cool air discharge ports through which cool air is supplied into a cooling compartment. In a cool air duct are installed shutter members for opening/closing the ports. The shutter members are installed a positions opening the ports, and are driven by a cam rotated by a motor. The ports and the shutter members are disposed symmetrically around the cam. As the cam rotates, the shutter members close the ports in turn. When a specific area becomes a desired temperature, a port corresponding to the specific area is closed by the shutter members. Thus, the area in the compartment to which cool air is supplied can be regulated, and the overcooling of the compartment can be prevented.Type: GrantFiled: July 29, 1998Date of Patent: April 4, 2000Assignee: Samsung Electronics Co., Ltd.Inventor: Joon Dong Ji

Patent number: 6029460Abstract: Disclosed is a method of controlling a cool air dispersing operation of a refrigerator for maintaining the temperature in a cooling compartment uniform. Many horizontal dispersing blades and vertical dispersing blades of planar plate shape, which respectively control the horizontal and vertical discharge directions of cool air are installed in a cool air duct. The blades are continuously rotated while a deviation of temperature in the cooling compartment is smaller than a predetermined value, whereby the cool air in the cooling compartment is successively supplied into the respective areas in the cooling compartment. Meanwhile, if the deviation is greater than the predetermined value, the blades are stopped at a specific position so that the cool air is discharged toward an area of which temperature is high. Thus, the temperature in the cooling compartment becomes uniform in a short period of time. Further, no vortex of cool air is generated since the blades are shaped into a planar plate.Type: GrantFiled: September 29, 1998Date of Patent: February 29, 2000Assignee: Samsung Electronics Co., Ltd.Inventor: Joon Dong Ji

Patent number: 6006529Abstract: Disclosed is a refrigerator having a cool air dispersing device capable of dispersing cool air horizontally and vertically. In a duct of a fresh food compartment are installed a horizontal dispersing blade for dispersing the cool air flowing thereinto horizontally and a vertical dispersing blade for dispersing it vertically. The horizontal dispersing blade is rotated by a motor, and the rotation of the motor is transmitted to the vertical dispersing blade as an elevational/de-elevational movement. Thus the vertical dispersing blade is rotated while the horizontal dispersing blade is rotated, whereby the cool air discharged into the compartment is dispersed horizontally and vertically. Therefore, the temperature in the compartment is maintained uniform.Type: GrantFiled: July 14, 1998Date of Patent: December 28, 1999Assignee: Samsung Electronics Co., Ltd.Inventors: Joon Dong Ji, Jae In Kim

Patent number: 5987904Abstract: A refrigerator which has a device for opening/closing cool air discharge ports is disclosed. The device includes plates for opening/closing the ports, and an operation member having racks for driving the plates, and a motor for driving the operation member. The heat exchange between an evaporator and the outside warm air is prevented during the defrosting operation and when a door is open. Hence the cooling efficiency is enhanced and the frost caused by the outside warm air is not generated on the evaporated.Type: GrantFiled: April 3, 1998Date of Patent: November 23, 1999Assignee: Samsung Electronics Co., Ltd.Inventors: Jae-in Kim, Jun-dong Ji
