Strong evidence suggests that dysregulated lipid metabolism involving dysfunction of the retinal pigmented epithelium (RPE) underlies the pathogenesis of age-related macular degeneration (AMD), the leading cause of irreversible blindness in the elderly. A hallmark of AMD is the overproduction of lipid- and protein-rich extracellular deposits that accumulate in the extracellular matrix (Bruch's membrane (BrM)) adjacent to the RPE. We analyzed apolipoprotein A-1 (ApoA-1)-containing lipoproteins isolated from BrM of elderly human donor eyes and found a unique proteome, distinct from high-density lipoprotein (HDL) isolated from donor plasma of the same individuals. The most striking difference is higher concentrations of ApoB and ApoE, which bind to glycosaminoglycans. We hypothesize that this interaction promotes lipoprotein deposition onto BrM glycosaminoglycans, initiating downstream effects that contribute to RPE dysfunction/death. We tested this hypothesis using two potential therapeutic strategies to alter the lipoprotein/protein profile of these extracellular deposits. First, we used short heparan sulfate oligosaccharides to remove lipoproteins already deposited in both the extracellular matrix of RPE cells and aged donor BrM tissue. Second, an ApoA-1 mimetic, 5A peptide, was demonstrated to modulate the composition and concentration of apolipoproteins secreted from primary porcine RPE cells. Significantly, in a mouse model of AMD, this 5A peptide altered the proteomic profile of circulating HDL and ameliorated some of the potentially harmful changes to the protein composition resulting from the high-fat, high-cholesterol diet in this model. Together, these results suggest that targeting HDL interactions with BrM represents a new strategy to slow AMD progression in humans.
A multinational team works on the capture mission, linked together by video and voice systems. Aerial surveillance is provided by a USAF MQ-9 Reaper drone controlled from Creech Air Force Base in Nevada by Second Lieutenant Steve Watts. Undercover Kenyan field agents, including Jama Farah, use short-range ornithopter and insectothopter cameras to link in ground intelligence. Kenyan special forces are positioned nearby to make the arrest. Facial recognition to identify human targets is done at Joint Intelligence Center Pacific at Pearl Harbor in Hawaii. The mission is supervised in the United Kingdom by a COBRA meeting that includes British Lieutenant General Frank Benson, two full government ministers and a ministerial under-secretary.
Farah discovers that the three high-level targets are now arming two suicide bombers for what is presumed to be an attack on a civilian target. Powell decides that the imminent bombing changes the mission objective from "capture" to "kill". She requests Watts to prepare a precision Hellfire missile attack on the building, and solicits the opinion of her British Army legal counsel. To her frustration, her counsel advises her to seek approval from superiors. Benson asks permission from the COBRA members, who fail to reach a decision and refer the question up to the UK Foreign Secretary, presently on a trade mission to Singapore. He does not offer a definite answer and defers to the United States Secretary of State, who immediately declares the American suicide bomber an enemy of the state. The Foreign Secretary then insists that COBRA take due diligence to minimise collateral damage.
Alia, who lives next door, is now near the target building selling her mother's bread. The senior military personnel stress the risk of letting would-be suicide bombers leave the house. The lawyers and politicians involved in the chain of command argue the personal, political and legal merits of and justification for launching a Hellfire missile attack in a friendly country not at war with the US or UK, with the significant risk of collateral damage. Watts can see the more direct risk of little Alia selling bread outside the targeted building, and they seek to delay firing the missile until she moves.
"The Actor and the Target comes from the heart of his own experience. Fear, generalising and other actor's blocks are dismembered lethally and with infectious relish." Alan Rickman"Brilliantly direct, the 'target' equips the actor with keys to unlock the fears and flab of acting. Declan's insightful voice guides us to the heart of the process; exhilirating to read and more importantly to put into practice." Joseph Fiennes."Cuts open every generalisation about acting and draws out gleamingly fresh specifics." Peter Brook
Dr. Rickman earned her doctorate in Astronomy and Astrophysics from Geneva Observatory in 2020, where she also spent some time as a postdoctoral researcher. She was then awarded a fellowship with the European Space Agency at STScI. Prior to earning her PhD, Dr. Rickman graduated from the University of Sheffield with a first-class Masters degree with honors in Physics and Astrophysics, including spending one year as a researcher at the Australian National University. Dr. Rickman is very passionate about diversity and inclusion in STEM, serving on several diversity committees, and having participated in numerous events targeted at encouraging women and members of the LGBTQ+ community into science.
Our chiropractors will invite a patient in and start with a consultation. During this appointment, the patient will describe all their symptoms to the chiropractor. What makes our work different is that instead of prescribing medications or treatments that erase the symptoms of pain, we work on reducing the target of the pain itself.
"This is game changing discovery in our field," said Dr. Jonathan W. Simons, president and CEO of the Prostate Cancer Foundation. "By identifying new molecular drivers of the most aggressive forms of prostate cancer, we can enable new strategies for targeted pharmacology research and development that could lead to durable remissions. Through development of new NEPC models, Dr. Rickman and his team have identified a population of patients that may respond to a new investigational treatment."
"Prostate cancer is very often linked to a mutation and over-expression in a gene called ERG that many people thought was undruggable, meaning there's no way to target the mutation with medications to disrupt the disease," said Dr. Olivier Elemento, one of the study's senior authors, and associate professor in the Department of Physiology and Biophysics and associate director of the HRH Prince Alwaleed Bin Talal Bin Abdulaziz Alsaud Institute for Computational Biomedicine at Weill Cornell Medicine.
"There's also a significant proportion of other cancer subtypes that are driven by mutations considered undruggable," said Dr. Rickman, adding that some colon cancers and lymphomas are among these. "The techniques used in this study may help us find ways to repurpose already existing safe drugs to target other undruggable mutations."
The spatial distribution of the target (t-) SNARE proteins (syntaxin and SNAP-25) on the plasma membrane has been extensively characterized. However, the protein conformations and interactions of the two t-SNAREs in situ remain poorly defined. By using super-resolution optical techniques and fluorescence lifetime imaging microscopy, we observed that within the t-SNARE clusters syntaxin and SNAP-25 molecules interact, forming two distinct conformations of the t-SNARE binary intermediate. These are spatially segregated on the plasma membrane with each cluster exhibiting predominantly one of the two conformations, representing the two-and three-helical forms previously observed in vitro. We sought to explain why these two t-SNARE intermediate conformations exist in spatially distinct clusters on the plasma membrane. By disrupting plasma membrane lipid order, we found that all of the t-SNARE clusters now adopted a single conformational state corresponding to the three helical t-SNARE intermediates. Together, our results define spatially distinct t-SNARE intermediate states on the plasma membrane and how the conformation adopted can be patterned by the underlying lipid environment.
