Lugar, a veteran disarmament campaigner, first suggested more than a year ago that the United States and Russia work together to secure Syria's stockpile of chemical weapons. Tim Webber's visual effects are nothing short of ground-breaking.
For the first time inPSC Partners Seeking a Cure, along with our Canadian affiliate, are delighted to award two Young Investigator Awards to promising researchers who are at the early stages of their research career and are interested in clinical, translational or basic research on Primary Sclerosing Cholangitis.
Please keep reading for a list of the titles, lead investigators, and lay summaries of all projects that buy research peptides uk map receive funding this year. Primary sclerosing cholangitis PSC is characterized by expanded bile ducts and liver fibrosis.
Extracellular vesicles are membrane-surrounded particles secreted from cells. These vesicles play an important role in liver diseases because they are transferred from donor cells and regulate cell events in recipient cells.
These vesicles carry cargo mediators, such as proteins and RNAs, and they can be used to control cell conditions. Our preliminary study has demonstrated that liver conditions in PSC could be improved or managed by these vesicles. In this buy research peptides uk map study, we hypothesize that extracellular vesicles can be used as a novel therapeutic tool to regulate PSC by delivering cargo mediators.
This study will establish novel methodology for the management of PSC using extracellular vesicles. Treatments using these vesicles will be less invasive with no or limited side effects.
The technique developed in this study could be used for treatments of other disorders. It is hard to study PSC due to a lack of adequate human samples for research, especially since bile duct cells do not grow well once removed from the body.
An additional challenge is to understand the immunologic imbalance in this autoimmune disease and to generate effective treatments to target the immune system. Our project will use organoids, which are collections of stem cells grown in the lab that resemble bile duct cells, to study PSC and its immune basis.
We will develop organoids from human bile, which is a new method that allows us to easily take a small amount of bile when a patient undergoes an ERCP procedure as part of their clinical care.
We will grow the organoids from patients with PSC and see how they interact with white cells T-lymphocytes obtained from the blood of patients with PSC seen at our clinics. We will also perform screening of potential drugs to treat PSC by exposing organoids to these compounds and observing if they can reduce inflammation.
Lastly, we will relate individual organoid findings with the clinical characteristics of the patient who donated the bile. Through this project we hope to better understand, in a personalized way, the nature of the immune imbalance in PSC and search for effective drugs using organoids grown from bile.
Primary sclerosing cholangitis PSC is a chronic progressive liver disease with a high risk of death, need of liver transplantation LTx or development of cholangiocarcinoma CCA within years after diagnosis.
There is no medical treatment that can halt PSC progression. Treatment with statins has shown to be beneficial in other chronic liver diseases than PSC.
Therefore, we tested the hypothesis that statins improve prognosis in PSC. Since there is no pharmacological treatment available in PSC, a study with statins seems highly motivated. We want to perform a long-term randomized double-blind controlled trial of atorvastatin versus placebo in patients with PSC.
To reach adequate power patients will be included and the study period is 5 years. Through this observational study performed by the network for liver studies in Sweden SweHepwe have an infrastructure for PSC studies already in place.
Primary sclerosing cholangitis, PSC, is a rare, chronic, and progressive cholestatic liver disease that can be complicated by biliary infection, hepatobiliary malignancy, and end stage liver disease. There is no known effective therapy and while the natural history of PSC is variable, in general, patients tend towards progressive liver disease and transplantation.
Recurrent PSC rPSC is a distressing complication that occurs in some PSC patients post liver transplantation and is associated with a four-fold increased risk of graft failure or death.
This research is directed at developing an improved understanding of clinical and immunopathogenic pathways underpinning recurrent PSC.
We aim to comprehensively characterize phenotype a prospective cohort of patients with PSC post liver transplant and use newly emergent mass cytometry technology to understand clinical, serologic, microbiological, and immunologic changes associated with development of rPSC.
In addition, we will establish an international network among liver transplant centers worldwide to characterize clinical risk factors associated with rPSC.
This disease is devastating to patients and their families, is costly to the health care system, and is a critical unmet need. Identifying clear risk factors for rPSC requires a systematic and comprehensive phenotypic evaluation of patients to identify those in greatest need of targeted early intervention.
Primary sclerosing cholangitis PSC is a chronic liver disease of unknown cause and pathogenesis with an unmet medical need. Thus, the development of novel therapies is eagerly awaited. Vitamin D exerts anti-inflammatory and anti-fibrotic effects by the activation of the vitamin D nuclear receptor VDR.
Unexpectedly, the treatment with a vitamin D analog, or vitamin D supplementation in the diet alleviated PSC features in these mice suggesting the existence of a Vdr-independent mechanism activated by vitamin D.
A protein called disulfide isomerase family A member 3 PDIA3 that mediates some rapid actions of Vitamin D could orchestrate these effects. Primary Sclerosing Cholangitis PSC is a disease affecting the bile ducts, causing obstructive flow of bile into the intestines.
PSC is characterized by increased inflammation, scarring and reduced bile duct regeneration. The pathogenesis of PSC is poorly understood but has been suggested to be immune mediated. T regulatory cells Trega cell type specialized in controlling immune response play an important role in the pathogenesis of autoimmune liver disease such as PSC.Righteous Research Peptides And Research Chemicals.
