Abstract:
본발명은프락시넬론(Fraxinellone) 화합물또는이의약제학적으로허용가능한염을유효성분으로포함하는골 질환치료또는예방용조성물에관한것이다. 본발명에따른프락시넬론화합물또는이의약제학적으로허용가능한염을유효성분으로포함하는골 질환치료또는예방용약제학적조성물은 Th17 세포분화와이에관여하는전사인자의활성을감소시킬수 있고, 형질세포(plasma cell)의분화와이의항체생산을억제할수 있으며, 파골세포(osteoclast)의분화를억제하는효과가뛰어나골질환의치료제로서매우유용하게활용될수 있다.
Abstract:
본 발명은 CD105, CD29 및 CD44는 양성이며 CD34, CD45 및 HLA-DR는 음성의 면역학적 특징을 갖는 간엽줄기세포에 메트포민을 처리하여, 28~42℃의 온도에서 14 ~ 21일 동안 배양하는 단계를 포함하는, 인간형질전환 성장인자-베타(TGF-β)를 대량생산하고 면역조절능을 갖는 간엽줄기세포의 제조방법 및 상기 방법으로 제조된 간엽줄기세포, 상기 간엽줄기세포를 함유하는 면역질환 치료 또는 예방용 세포치료제 조성물에 관한 것이다. 본 발명에 따른 메트포민이 처리된 면역조절능을 갖는 간엽줄기세포는 면역조절능을 갖는 인자인 IDO, TGF-beta 또는 IL-10의 발현이 증가되어 있고, 자가포식작용 및 미토콘드리아 활성을 증가되어 있어 면역질환 치료를 위한 세포치료제로 유용하게 사용할 수 있는 효과가 있다.
Abstract:
The present invention relates to a composition for preventing or treating arthritis or osteoporosis comprising extract of glehnia littoralis as an active ingredient. According to the present invention, the extract of glehnia littoralis has excellent activity to reduce or inhibit activity of inflammatory cytokines such as IL-17, IL-6, or TNF-, and has an improved effect of reducing osteoclast differentiation, thereby being used as a composition for preventing or treating arthritis or osteoporosis. Also, the extract of glehnia littoralis does not cause cytotoxicity, has no toxicity and side effects to the drug, thereby being safely used even in long-term use, and can be stable in vivo.
Abstract:
PURPOSE: An immunotherapeutic agent of a nanosome form containing retinoic acid is provided to ensure high retinoic acid transfer rate to a target site and to effectively suppress TNF-alpha and IL-17 generation. CONSTITUTION: An immunotherapeutic agent of a nanosome form contains a cell suspension and retinoic acid. The cell suspension is a cell membrane in eukaryotic cell lysate. The immune diseases are autoimmune diseases, inflammatory diseases, and cell, tissue, or organ transplantation rejection. A method for manufacturing the immunotherapeutic agent comprises: a step of suspending eukaryotic cells; a step of passing the suspension solution through a membrane filter; a step of adding retinoic acid to the solution; and a step of isolating immunotherapeutic agent of a nanosome from the solution.
