  • Patent number: 8617546
    Abstract: Provided is an anticancer agent which comprises an anti-PD-1 antibody or an anti-PD-L1 antibody as an active ingredient, functioning to reverse the unresponsiveness of iNKT cells in which anergy has been induced by administration with an iNKT cell ligand. The anti-PD-1 or anti-PD-L1 antibody blocks the PD-1/PD-L1-mediated signaling pathway not only to prevent the iNKT cell ligand-induced iNKT cell anergy, but also to reverse the unresponsiveness of already anergic iNKT cells to produce cytokines. In addition, the anti-PD1 or anti-PD-L1 antibody ensures the potent anti-tumor activity of iNKT cells as demonstrated by a significant reduction in the number of metastatic nodules in B16F10 melanoma metastasis models in vivo. Collectively, the anticancer agent can be very useful in the treatment of cancer, particularly metastatic cancer.

  • Patent number: 7032404
    Abstract: Disclosed is air conditioner having an indoor part and an outdoor part as one unit. The air conditioner including: an indoor part for inhaling an indoor air to exchange heat with the inhaled air through an indoor heat exchanger, and again discharging the heat-exchanged air into an indoor space; an outdoor part for inhaling an outdoor air to exchange heat with the inhaled air through an outdoor heat exchanger, and again discharging the heat-exchanged air into an outdoor space; a base having parts constituting the indoor part and the outdoor part installed thereon; and a barrier integrated with the base, for partitioning an upper space of the base into the indoor part and the outdoor part.
