New paper! Angpt2 is a key adipokine driving lipid accumulation into the SAT.
June 15, 2020
Scientists at IBS Center for Vascular Research have reported Angpt2 as a key adipokine driving lipid accumulation into the SAT. This is through endothelial FA transport mediated by Angpt2- integrin α5β1 signaling, which prevents ectopic fat accumulation into endocrine organs, and thus prevents insulin resistance. Their findings have been reported in the journal Nature Communications on June 12.

Unveil how stromal cells in the lymph node regulate immune response!
February 07, 2020
IBS Scientists have reported the key signaling pathway governing the integrity of FRCs in modulating immune responses. They found that the Hippo-YAP/TAZ signaling pathway plays dominant roles in regulating the immune-responsive features of FRCs. They confirmed through genetically modified mouse models that deletion or hyperactivation of YAP/TAZ led to impaired differentiation and maintenance of FRCs to varying degrees, leading to disrupted formation and compartmentalization of LNs and their immune responsiveness.

New paper for answering the key question about brain clearance is published!
July 25, 2019
Scientists led by Dr. Gou Young Koh at the Institute for Basic Science (IBS) revealed an accurate route of cerebrospinal fluid drainage and characterized meningeal lymphatic vessels at the skull base for the first time, in the July 24 Nature.
Therapies targeting abnormally accumulated protein such as beta-amyloid for patients with Alzheimer’s disease are currently being actively developed. By drawing the clear roadmap of exit route for macromolecules leaving the brain found by this study, researchers may be able to find a link between dysfunction of this system and the accumulation of toxic metabolites within the brain. Dr. Koh says, “It definitely warrants more extensive investigation of meningeal lymphatic vessels in patients with age-related neurodegenerative disease such as Alzheimer’s disease prior to clinical investigation.”

Tumor metastasis to lymph node requires metabolic reprogramming to use fatty acid as a fuel.
February 08, 2019
Researchers at IBS Center for Vascular Research discovered the mechanism how metastatic tumor cells grow in lymph nodes. The study revealed that tumor cells undergo a metabolic reprogramming toward fatty acid oxidation (FAO). Transcriptional co-acitvator YAP, potentially activated by accumulated bile acids, was selectively activated in LN metastatic tumors, leading to the up-regulation of genes in the FAO signaling pathway. This study propose that inhibition of FAO or YAP signaling to prevent the metabolic adaptation of metastatic tumors offers a potential therapeutic strategy for mitigating tumor LN metastasis. This study was published in Science at February 8 2019.Choong-kun Lee, Seung-hwan Jeong, Cholsoon Jang, Hosung Bae, Yoo Hyung Kim, Intae Park, Sang Kyum Kim, Gou Young Koh.

New paper for Angiopoietin/Tie2 signaling in maintaining Schlemm’s canal integrity
September 19, 2017
Researchers at IBS Center for Vascular Research identified a critical role of angiopoietin/Tie2 signaling in maintaining Schlemm’s canal integrity. Impairment of this signaling could be involved in the pathogenesis of primary open-angle glaucoma, the most common form of glaucoma. Of special note, intraocular administration of Tie2 activator reduces the elevated intraocular pressure and recovers regressed Schlemm’s canal in glaucoma animal model, suggesting one of therapeutic options for glaucoma. This study was published in Journal of Clinical Investigation at September 18 2017 and highlighted as a Cover Story.Jaeryung Kim, Dae-Young Park, Hosung Bae, Do Young Park, Dongkyu Kim, Choong-kun Lee, Sukhyun Song, Tae-Young Chung, Dong Hui Lim, Yoshiaki Kubota, Young-Kwon Hong, Yulong He, Hellmut G.

New paper - Develop a new therapeutic approach to normalize tumor vessels!
December 13, 2016
Researchers at IBS Center for Vascular Research have discovered a treatment to normalize tumor vessels. Their antibody ABTAA (Ang2-Binding and Tie2-Activating Antibody), which was also highlighted as an anti-sepsis antibody, reduced tumor volume and improved the delivery of anti-cancer drugs.
Researchers tested ABTAA in mice with three different types of tumors that show high levels of Ang2: glioma, lung carcinoma and breast cancer. They also compared the effect of ABTAA with ABA, another antibody that blocks Ang2 but misses the Tie2 activating properties. In all three cases, ABTAA was superior to ABA in inducing tumor vessel normalization, which led to a better delivery of the anti-cancer drugs into the tumor core region. Therefore, ABTAA reduced glioma growth, lung and breast cancer progression in mice.Jin-SungPark, Il-Kug Kim, Sangyeul Han, Intae Park, Chan Kim, Jeomil Bae, Seung Ja Oh, Seungjoo Lee, Jeong Hoon Kim, Dong-Cheol Woo, Yulong He, Hellmut G.

New paper - Researchers develop a new therapeutic approach to sepsis!
December 13, 2016
IBS Researchers have conducted a treatment for sepsis, which is difficult to treat and life-threatening due to components such as vascular disintegration and leakage. The authors developed an antibody that stimulates TIE2, a cell surface receptor tyrosine kinase that is highly expressed on endothelial cells. The antibody, called ABTAA, which binds to ANG2 and activates TIE2 integrates the endothelium to fortify intercellular junctions and to reduce the expression of adhesion molecules for leukocytes. As a result, activated TIE2 promotes barrier defense against vascular leakage and counteracts vascular inflammation. This new therapeutic approach greatly increases the survival rate during sepsis, by protecting the vascular walls and blunting septic damage. The study was highlighted as a focus article and also selected as a cover in the leading biomedical journal, Science Translational Medicine.Sangyeul Han, Seung-Jun Lee, Kyung Eun Kim, Hyo Seon Lee, Nuri Oh, Inwon Park, Eun Ko, Seung Ja Oh, Yoon-Sook Lee, David Kim, Seungjoo Lee, Dae Hyun Lee, Kwang-Hoon Lee, Su Young Chae, Jung-Hoon Lee, Su-Jin Kim, Hyung-Chan Kim, Seokkyun Kim, Sung Hyun Kim, Chungho Kim, Yoshikazu Nakaoka, Yulong He, Hellmut G.
