Neural Regeneration Research 2022年第1期17卷 95-96页

作者： Amanda M.Crooks Rick B.meeker UNC School of Medicine University of North CarolinaChapel HillNCUSA(Crooks AM)Department of NeurologyUniversity of North CarolinaChapel HillNCUSA

Neurotrophins have been recognized for decades for their beneficial effects on growth,survival,and maintenance in the central nervous system,all of which suggest potential therapeutic *** understanding and harnessing the activity of neurotrophins has proven difficult,the past several years have seen significant strides in the development of deliverable therapies that modulate neurotrophin activity(Shen et al.,2019;Yang et al.,2020;Xie et al.,2021).These recent studies have primarily focused on the multifunctional p75 neurotrophin receptor(p75NTR)which is upregulated in central nervous system disease and injury,thus offering a unique target for intervention.

The p75 neurotrophin receptor:at the crossroad of neural repair and death

引用

Neural Regeneration Research 2015年第5期10卷 721-725页

作者： Rick B.meeker Kimberly S.Williams Department of Neurology University of North Carolina Curriculum in Neurobiology University of North Carolina

The strong repair and pro-survival functions of neurotrophins at their primary receptors, TrkA, TrkB and TrkC, have made them attractive candidates for treatment of nervous system injury and disease. However, difficulties with the clinical implementation of neurotrophin therapies have prompted the search for treatments that are stable, easier to deliver and allow more precise regula- tion of neurotrophin actions. Recently, the p75 neurotrophin receptor （p75wrR） has emerged as a potential target for pharmacological control of neurotrophin activity, supported in part by stud- ies demonstrating 1） regulation of neural plasticity in the mature nervous system, 2） promotion of adult neurogenesis and 3） increased expression in neurons, macrophages, microglia, astro- cytes and/or Schwann cells in response to injury and neurodegenerative diseases. Although the receptor has no intrinsic catalytic activity it interacts with and modulates the function of TrkA, TrkB, and TrkC, as well as sortilin and the Nogo receptor. This provides substantial cellular and molecular diversity for regulation of neuron survival, neurogenesis, immune responses and pro- cesses that support neural function. Upregulation of the p75^NTR under pathological conditions places the receptor in a key position to control numerous processes necessary for nervous system recovery. Support for this possibility has come from recent studies showing that small, non-pep- tide p75^NTR ligands can selectively modify pro-survival and repair functions. While a great deal remains to be discovered about the wide ranging functions of the p75^NTR, studies summarized in this review highlight the immense potential for development of novel neuroprotective and neu- rorestorative therapies.

Protective links between vitamin D,inflammatory boweldisease and colon cancer

引用

World Journal of Gastroenterology 2016年第3期22卷 933-948页

作者： Stacey meeker Audrey Seamons Lillian Maggio-Price Jisun Paik Department of Comparative Medicine University of WashingtonSeattleWA 98195United States

Vitamin D deficiency has been associated with a wide range of diseases and multiple forms of cancer including breast, colon, and prostate cancers. Relatively recent work has demonstrated vitamin D to be critical in immune function and therefore important in inflammatory diseases such as inflammatory bowel disease(IBD). Because vitamin D deficiency or insufficiency is increasingly prevalent around the world, with an estimated 30%-50% of children and adults at risk for vitamin D deficiency worldwide, it could have a significant impact on IBD. Epidemiologic studies suggest that low serum vitamin D levels are a risk factor for IBD and colon cancer, and vitamin D supplementation is associated with decreased colitis disease activity and/or alleviated symptoms. Patients diagnosed with IBD have a higher incidence of colorectal cancer than the general population, which supports the notion that inflammation plays a key role in cancer development and underscores the importance of understanding how vitamin D influences inflammation and its cancer-promoting effects. In addition to human epidemiological data, studies utilizing mouse models of colitis have shown that vitamin D is beneficial in preventing or ameliorating inflammation and clinical disease. The precise role of vitamin D on colitis is unknown; however, vitamin D regulates immune cell trafficking and differentiation, gut barrier function and antimicrobial peptide synthesis, all of which may be protective from IBD and colon cancer. Here we focus on effects of vitamin D on inflammation and inflammation-associated colon cancer and discuss the potential use of vitamin D for protection and treatment of IBD and colon cancer.
