Abstract: A strain sensor may have a conductive elastic yarn including a first fiber having a predetermined length and a shape of a fiber yarn and a second fiber having electrical conductivity and a sheet shape. The strain sensor may have a pair of wiring members electrically connected to both ends of the conductive elastic yarn. The conductive elastic yarn, with the second fiber wrapped around the first fiber, is twisted in a coil shape.

Abstract: The present invention relates to a fusion protein composed of the extracellular domain of PD-L1 and a modified immunoglobulin Fc region. The extracellular domain of PD-L1 and a fragment thereof have excellent immunomodulatory activity, and can be used as an immunomodulatory agent if a modified immunoglobulin Fc region is coupled thereto. Accordingly, the PD-L1 fusion protein according to the present invention demonstrated its excellent effect in disease models of inflammatory bowel disease, colitis, psoriasis, asthma and arthritis, and thus can be very effectively used for the treatment of such diseases.
