Abstract: Disclosed is a user authentication-based packet classification method and apparatus for providing differentiated security services in a ship network. A user authentication-based packet classification method includes receiving an authorization code request message from a user terminal including a client, authenticating and authorizing a user of the client based on the authorization code request message, transmitting an authorization code response message to the user terminal in response to the authorization code request message, receiving an access token request message from the user terminal based on the authorization code response message, and transmitting an access token response message including an access token to the user terminal in response to the access token request message.

Abstract: The present invention relates to a pharmaceutical composition comprising a novel compound as an active ingredient for prevention or treatment of transplant rejection. The novel compound SD911 of the present invention was identified to repress the migration of immune cells, increase the engraftment and viability of a grafted tissue, and regulate immune cells. In addition, it was found in a kidney transplantation model that the compound restrained human PBMC from suppressing the engraftment and damaging renal tissues and downregulated the expression of the inflammatory cytokine IL-17, with the consequent effective prevention and treatment of transplant rejection.

Abstract: Provided are a method for fabricating a human nasal turbinate-derived mesenchymal stem cell-based 3D bioprinted construct, and a use thereof, wherein the human nasal turbinate-derived mesenchymal stem cell-based, 3D bioprinted construct is advantageous over conventional mesenchymal stem cell-based, 3D bioprinted constructs in that the former can survive and proliferate stably in vitro and/or in vivo and shows high osteogenic differentiation ability as well, therefore is expected to make a great contribution to the practical use of cellular therapeutic agents.

Abstract: Provided is a novel compound and use thereof which has an excellent immunological regulation ability while not exhibiting toxicity in vivo, and has no nephrotoxicity and rather has a kidney protective effect, and thus can be used for the treatment of immune diseases such as autoimmune diseases caused by abnormal regulation of various immune responses, inflammatory diseases, and transplant rejection diseases. A transplant rejection avatar animal model was confirmed to be humanized, by confirming an increase in serum creatinine, an indicator of transplant rejection in a patient, an increase in human CD4-positive cells, and infiltration of inflammatory cytokine IL-17 into kidney tissue of the animal model. It was confirmed that, when an immunosuppressant is administered, the increased serum creatinine, human CD4-positive cells, and the infiltration of inflammatory cytokine IL-17 are reduced, and thus an animal model, in which the immune status of a patient is reflected, is effectively constructed.

Abstract: The present invention relates to a composition for preventing or treating mitochondrial diseases caused by immunosuppressants, and immune diseases, containing metformin and, more specifically, to a composition for treating mitochondrial diseases caused by immunosuppressants, containing metformin; a pharmaceutical composition for preventing or treating immune diseases, containing, as active ingredients, metformin and an immunosuppressant, which is a target of rapamycin inhibitor (mTOR inhibitor); and a pharmaceutical composite formulation for preventing or treating immune diseases, containing, as ingredients, metformin and a mammalian target of rapamycin inhibitor, wherein the metformin and mammalian target of rapamycin inhibitor are administered simultaneously or separately, or administered in a predetermined sequence.

Abstract: Provided is a composition for alleviating nephrotoxicity caused by an immunosuppressive drug, including metformin, and a composition for preventing or treating an immune disease, including the same. Further, the composition provided can be useful in improving a treatment effect on diseases requiring immunosuppression by effectively alleviating a decline in renal function caused due to side effects of conventional immunosuppressive drugs, and can also be useful in preventing or treating organ transplant rejection, autoimmune diseases, inflammatory diseases and the like since various methods of co-administering a conventional immunosuppressive drug and metformin are suggested to reduce nephrotoxic side effects of conventional immunosuppressive drugs and maximize immunosuppressive or immunomodulatory effects.
