We study how immune cells go awry in pediatric inflammatory, allergic, autoimmune and autoinflammatory conditions。 We strive to identify key pathogenic mechanisms and develop novel diagnostic and treatment methods that may improve the quality of life in children。 Cutting-edge technologies, including disease-causal and risk gene identification, single-cell based disease tissue profiling, and mechanistic exploration using bioinformatic, biochemical, immunological and animal model studies, have shaped our approach in helping the clinicians to achieve personalized diagnosis and pathogenesis-based treatment practice。

In collaboration with Gastroenterology Department of GWCMC and Peking University, we performed single-cell and risk gene analysis of children with undifferentiated colitis, Crohn’s disease and ulcerative colitis。 This has identified that a common underlying mechanism of pathogenesis is the defective cAMP signaling, which results in CD39+ intraepithelial T cell (CD39+IET) deficiency, macrophage hyperinflammation and platelet aggregation at the colonic mucosae。 This study has led to a successful pilot trial using a pan-phosphodiesterase inhibitor dipyridamole for the treatment of children with colitis。

In collaboration with the Barwon Infant Study and the Walter & Eliza Hall Institute of Medical Research, we identify that hyper-inflammation at birth is a key pathogenic mechanism that may lead to IgE-mediated food allergy (Sci Transl Med) and chronic colitis (Front Immunol) in children。

In collaboration with Immunology Department of GWCMC and the Walter & Eliza Hall Institute of Medical Research, we identified a novel mutation in the inflammasome protein NLRC4, which has proven to cause macrophage activation syndrome with complex clinical presentations。

Research background:
Yuxiaobtained her PhD from the Chinese Academy of Sciences in 2007, followed by 2 years post-doctoral training in the Christopher Rudd Laboratory at the University of Cambridge (UK) (2007-2008)。 She joined the Leonard Harrison Lab at Walter and Eliza Hall Institute of Medical Research (WEHI) in February 2009 and was promoted to Senior Research Officer in 2014。 She was appointed Lab Head April 2016 at Guangzhou Women and Children’s Medical center (GWCMC), Guangzhou Medical University。 She bridges mouse and human immunology studies with cutting-edge epigenetic, metabolomic and cell signaling methodologies, and has identified novel biomarkers and pathogenic mechanisms in autoimmune and allergic diseases, and therapeutic targets and agents。
Her lab currently focuses on immune pathogenesis and novel treatment strategies for inflammatory bowel diseases (IBD) and biliary atresia (BA).They employ cutting-edge techniques including single cell RNA sequencing, whole genome-wide association study, whole exosome sequencing, comparative immune profiling, animal experiments and clinical trials to identify how risk and disease causal genes regulate intestinal and hepatic immune and non-immune cell development and function。
张玉霞于2007年获得中国科学院大学博士学位,随后在英国剑桥大学接受了两年的博士后培训(2007-2008)。2009年2月,她加入了沃尔特•伊丽莎•霍尔医学研究所(WEHI),并于2014年晋升为高级研究官员。2016年4月,她受邀在广州医科大学广州妇女儿童医疗中心组建实验室。她通过免疫学、遗传学、表观遗传学、代谢组学和细胞信号传导等的交叉学科方法将小鼠和人类免疫学研究联系起来,发现了自身免疫性和过敏性疾病中的新的生物标志物和致病机制,以及治疗靶点和药物。
她的实验室目前专注于儿童消化系统慢病的免疫发病机制和新的治疗策略研究。他们采用包括单细胞RNA转录组测序、全基因组关联研究、全外显现子测序、比较免疫图谱、动物实验和临床试验的方法,确定疾病的风险和致病基因如何调节组织器官的功能稳态。
