Prion Disease

BSE (bovine spongiform encephalopathy) also known as Prion Disease, is a disease many are still trying to understand as to why it happens. “Prion diseases or transmissible spongiform encephalopathies (TSEs) are a rare progressive neurodegenerative disorders that affect both human beings and animals” (Aguzzi, 2001). They are known to follow a long incubation period, along with substance like a spongiform changes related with loss of neuronal, and a lack to be able to show inflammatory response. The organism description, is the causative agents of TSEs are believed to be prions. “The term "prions" refers to abnormal, pathogenic agents that are transmissible and are able to induce abnormal folding of specific normal cellular proteins called prion proteins that are found and seen the most in the brain. The functions of these normal prion proteins are still not completely understood.”(Aguzzi, 2001) “The abnormal folding of the prion proteins leads to brain damage and the characteristic signs and symptoms of the disease. Prion diseases are usually rapidly progressive and always fatal. It is known that the likelihood of obtaining prion disease is by age. The older you are the more prone you are to it. Several mathematical models proposed over the past years predicted that the frequency of the disease would level off to zero around the turn of the century.”(Aguzzi, 2001) Most deaths occurred after being contaminated with this disease if usually one year after the onset of illness. A lot of research is still being done to help prevent this disease but no luck yet, but scientists do not understand what normal prion protein does but have figured out that “scientists believe that abnormal prion protein, which clumps together and accumulates in brain tissue” (DeArmond, 2006), is the likely cause of the brain damage that occurs in TSE diseases. Prions disease is also known as Prions “Protein,” This deadly disease was responsible for known epidemics of living organism it attacked humans and animals. Scrapie is a disease with the reputation of killing sheep and goats and has been recognizable for more than 200 years in Europe and other parts of the world. This disease may be more common in some countries more than others due to lack of knowledge of sanitation procedures. This infectious disease has many different names like for example Jakob Disease (CJD), Gersmann-Straussler Syndrome (GSS) GerstmannStraussler-Scheinker- Disease, and Kuro. Its known to attack the the brain and normally during this time it was attacking millions of people worldwide crippling them.” (Annual Reviews, Inc. 2001, p. 2). Its also known to attack all kinds of species especially felines, wild and domestic as well as cows, goats, sheep, bison, deer, elks it makes sense why wild cats get it they are meat eaters. There was never no information of how this disease was brought to native lands, this still remains a mystery. In the United Kingdom about 180,000 cattle became sick, what was known is that the cows owners were feeding these animals with other cow flesh! This was one of the most known cases however it was also spread in the mid 50's affecting people of Eastern Highlands of Papua New Guinea. Kuru or Prions Disease was being transmitted by eating other humans flesh in my opinion I think maybe it would have helped if they would have fried the meat even thou its probably out of our boundaries and norms today. This killer disease Scrapie caused its host go through excruciating symptoms like fatigue, insomnia, depression, weight loss, headaches, and in general malaise. It causes psychological problems in humans, changes in behavior, and people may start to lose the ability to speak or do any activities and may lead to mental retardation. It shuts down the body little by little, in a blink of an eye you can just see death occurring, seem familiar with All Timers but thats just my comparison. Anyway It also causes cerebellar ataxia, this means that you will lack the ability of muscle coordination, its scary but its pretty much eating the brain alive. If no proper assistance is given to the host, it will die under a six months, if you lived around old times era, you could just watch people die. (Annual Reviews, Inc. 2001, p. 2). “However there are different ways of getting the disease, you may acquire it by eating infected flesh or if you were eating flesh of any kind for instance be smart about it and cook it.

Introduction to Prions

...Prions What Are They? Prions are proteinaceous transmissible pathogens, and are believed to infect and propagate the conformational changes of the native proteins into the the abnormally structured form. They are often called Spongiform Encephalopathies due to the swelling of the brain, accompanied with the observation of vacuoles like structures. Different prions affect different regions of the brain • Cerebral cortex: the symptoms include loss of memory and mental acuity, also visual imparement (CJD). • Thalamus: Fatal Familial Insomnia (FFI). • Cerebellum: lose the control of body movements and difficulties to walk (kuru, GSS). • Brain stem: In the mad cow disease (BSE), the brain stem is affected. 3 Formation Of A Prion (in the cell) α-helix β-sheet Conformational change PrPSc Normal protein (folded structure) PrPC Aggregation Gain of toxic activity Loss of biological function Disease-associated protein (misfolded structure) PrPC The normal protein is called PrPC (for cellular) is a transmembrane glycoprotein (neurons, lymphocytes); its function is unknown; it binds Cu2+ (regulation its homeostasis) PrPSc The abnormal, disease-producing protein is called PrPSc (for scrapie) has the same amino acid sequence (primary structure) is monomeric and easily digested by proteases is multimeric and resistant to digestion by proteases When PrPSc comes in contact with PrPC, it converts the PrPC into more of itself These molecules bind to......

Prions

...| Prion Disease | VET 140 Mr. Bell | Roger Meadows 5/7/2012 | A prion is a protein that has been mutated. Prion means proteinaceous infectious particle. Proteinaceous infectious particle can be broken down into:” proteinaceous which is relating to, resembling, or being protein, Infectious which is capable of causing infection, and particle which is a minute quantity or fragment” (Merriam – Webster 2012). So a proteinaceous infectious partial would be a very small protein that can cause an infection. The protein called PrP can be found in nerve cells all through the brain. The prion does not have a nucleus like other infectious dieses, and this makes it rare. Without the nucleus, it is not a virus or bacteria; it is only a protein (Hinz, A., Doremus, C., 1997). Prions cause a wide range of neurologic diseases in sheep, cows, and humans and were identified by Stanley Prusiner at UCSF in 1981 (Immunity and Disease, 2001). Prions are responsible for transmissible spongiform encephalopathies or TSE’s. Spongiform encephalopathies can develop three different ways, either by a normal prion changing into an abnormal one, or the PRNP gene that targets the creation of a protein which mutates into an abnormal protein, or consumption of contaminated items (Hinz, A., Doremus, C., 1997). TSE’s are very rare and affect around one person in every million each year over the world. TSE’s include bovine spongiform encephalopathy, or mad cow disease in cattle, scrapie in sheep,......

Folding can also result in covalent bonding between the "R" groups of cysteine amino acids, also known as a disulfide bridge (strongest bond). Van der Waals forces interactions help in the stabilization of protein structure. These interactions refer to to the attractive and repulsive forces that occur between molecules that become polarized. These forces contribute to the bonding that occurs between molecules. (Borges,2014) Bovine Spongiform Encephalopathy Mad cow disease or bovine spongiform encephalopathy is a deadly neurological disease that affects adult cattle. It is transmitted from animal to animal through contaminated food that contain infected central nervous system and spinal cord remnants. The contaminated food contain prions, a type of misfolded protein. A healthy brain prion protein (PrP) Is converted into a diseased PrPSc. “All known prions induce the formation of an amyloid fold, in which the protein polymerises into an aggregate consisting of tightly packed beta sheets. Amyloid aggregates are fibrils, growing at their ends, and...

Prion

...Prions are abundantly found in the brain. There are two different forms of prion proteins, a normal form and an abnormal form. The abnormal form of the prion protein can push the normal prions to change into an irregular misfolded shape. This process can damage normal prions by converting them to the abnormal shape. The normal form protein is found on nerve cells, but when it changes into its abnormal form, it combines into materials that affect the normal functioning of the brain. These proteins resist many techniques used to decontaminate food. They need very high temperatures and pressure. It is also not possible to irradiate prions. Because these processes do not easily destroy prions, they can be transmitted by consumption of infected meat, transfusions of blood, cannibalism and organ transplants. Other ways of acquiring the disease includes mutations in the prion gene, which is transmitted from parent to child, or they can arise spontaneously. Prion diseases are called transmissible spongiform encephalopathy - transmissible because they can infect others, spongiform for the sponge resemblance, and encephalopathy, which is the general term for brain disease. When the abnormal protein is ingested or accidentally gets into the blood, it can cause a severe disease. Even a small dose of abnormal prions can infect an entire organism. Prions are not counted as bacteria or viruses and are not recognized by the body as something dangerous and that is why they do not cause......

Corn Fed vs. Grass Fed

...Corn Fed vs. Grass Fed Have you noticed how there’s an increasingly wider selection of types of beef to be purchased? Which option is healthier? Which one is least expensive? There has been an ongoing dispute over which choice of beef we should be consuming. While both may seem to have their own advantage and disadvantage; ranging from being cost-efficient, to more beneficial nutrients. Both contribute to the eco-system, but in completely different ways. While grass-fed beef is the healthier alternative, it can prove to be a bit pricey, nonetheless, grass-fed beef provide us with more nutrients; they’re higher in Omega-3 fatty acid and vitamin E. Corn-fed beef, on the other hand, is relatively more affordable. The million dollar question should be, it’s affordable, but at what cost? What makes corn-fed beef so much cheaper than grass-fed? Corn-fed cattle go through a process, almost like an assembly line. The first step, the cow and calf live in a cow-calf operation. Here, the cow is artificially inseminated for the sole purpose of reproduction. For the first 6 months, the calf stays with their mother, once they’re old enough they’re taken to a pen, where they’re introduced to corn. To make a long story short, the calf is finally moved into a CAFO (confined animal feeding operation). From this point on, they’re all confined to small caged in areas. These facilities house hundreds, even thousands of farm animals. From this point on their diet is strictly corn, protein,......

Prions

...Ask and Answer Paper: Understanding Prions Ask and Answer Paper: Understanding Prions Steven English Ask and Answer Paper: Understanding Prions 1 As its name suggests, Pasteur's germ theory of disease simply states that microbes are the cause of disease. Though it seems obvious now, it was revolutionary at the time of its inception and is central to our modern understanding and treatment of diseases. It replaced the commonly held and relatively complex 'humoral theory' with a simpler concept that boiled down to a relationship between microorganism and host (“Germ Theory,” n.d.). But as our understanding of the disease process grows with more and more diseases continuing to be discovered, we find that while viruses and microorganisms might be the main cause they aren't the only way in which disease can spread. Prions are one such challenge to this simple germ-disease paradigm. In this paper, the following questions about prion diseases (focusing primarily on kuru and Creutzfeldt-Jakob disease) will be examined: “What are they and what does their discovery mean for our understanding of disease and evolution?” The prion protein (PrPC) is a protein seemingly found in the brains of almost all vertebrate animals......

Task 5

...also known as Prions. Prions can form by changes in DNA or mutations which result in a change of protein conformation. Chaperones provide an environment so proteins fold properly, bad chaperones influence the good chaperones to take form as harmful proteins. Eventually aggregates of these harmful proteins form and these aggregates lead to cell death. “The prion hypothesis suggest that diseases like BSE are caused by the misfolding of a protein known as PrP that most cells contain. Once a few copies of protein become misfolded they cause PrP’s to misfold, leading to accumulation of insoluble proteins in the cell. These misfolded proteins cause cell death and damage to the nervous system.” A country without regulations in place can help reduce risk of transmitting BSE by properly discarding possibly contaminated cattle feed. Brain and spinal cord matter should be discarded, and watching cattle with possible signs of BSE should not be introduced into the feed. One possible sign of BSE in cattle is not being able to walk, some may demonstrate aggressive behavior. The following statement is another possible way of introducing safe ways to discard contaminated cattle in a country without regulations: “According to Dr. Lisa Ferguson, a senior staff veterinarian at the Agriculture Department, said the department favored dissolving carcasses in tissue digestors, are essentially giant pressure cookers heated to 300 Fahrenheit.” This process is said to destroy the prions and reducing......

...hydrophobic interactions which is nonpolar. These R groups will cluster together on the interior of the protein and this will minimize their contact with water. The last one is van der Waals interactions takes place between the tightly packed nonpolar R groups on the interior of the protein. I would like to talk about BSE or bovine spongiform encephalopathy, in other words mad cow disease. This disease is called by misfolding prions at the molecular level. There are harmful and nonharmful forms of prions. The nonharmful form is PrPc and the harmful form is PrPsc. The PrPsc are hydrophobic and will cause the normal proteins to conform to their misfolding and harmful prion shape. This happens by way of a chaperonin. A polypeptide chain will enter the chaperonin and with proper environment of chaperonin, the polypeptide chain will fold correctly and exit as the normal prion, PrPc. Now in BSE, a polypeptide chain will enter into a “bad” chaperonin, the prion, and will get a misfolded prion to exit, PrPsc. The PrPsc will start to influence the normal proteins and in turn cause them to take the harmful prion shapes. The PrPsc will accumulate on the cell membrane and form fibers which will cause the cell to die. Now in countries that do not have regulations in place, to decrease the risk of BSE infecting their food source, you could not feed any animal remains to cattle. You could also...

Mad Cow Disease

...spongiform encephalopathy (BSE), better know as Mad cow disease is a relatively new disease. Most sources state that BSE first showed up in Great Britain in 1986 [Dealler p.5] but some say it popped up in 1985 [Greger p.1]. However the official notification was not until 21 June, 1988 [Dealler stats. p.1]. Spongiform encephalopathies are invariable fatal neurodegenerative diseases and there is no treatment nor is there a cure for this disease [Greger p.1]. The recent scare of BSE has arisen because of the contraction of Creutzfeldt-Jakob disease (CJD: see Appendix B) in humans from eating beef products. Although there are many forms of Spongiform encephalopathies that affect a wide range of animals, BSE has received the most attention because many people in the world consume beef and people are that they might contract the disease from eating a burger at their favourite fast-food restaurant. In this essay I will discuss BSE and other forms of Spongiform encephalopathies, how it affects the ani mal, what causes the animals to contract the disease, and the recent issues of BSE in the world. I hope to set out the true facts about BSE and that it only affects a small percent of the world population. Due to the fact BSE is a new disease most of my information might be proven wrong in the future because there is a great deal of testing going on in the scientific community. They are also very concerned about this new disease and the effects it can have on......

How the Zombie Apocalypse Is Totally Possible.

...How Zombies Could Actually Happen: A Research Paper Imagine a person infected with a disease to the point that they are some how no longer who they were before. The disease would take over the brain and make the body do only one thing, infect others. Sounds like a bad horror movie? Well think again. There are plenty of viruses, fungi, parasites, and chemicals in the world that affect the brain already and could cause such a thing to happen. The “zombie” wouldn’t be eating brains but it would want to spread the virus. Who is to say that a virus cannot mutate into something horrendous. This essay will show you that there are viruses, fungi, parasites, and chemicals that either can or have the potential to make people or animals into walking dead. Where did the idea of zombies come from? Zombies originated in Haiti as a sort of voodoo slave labor. What would happen was the person would be fed or rubbed with a mixture of the skin of the common toad and puffer fish. The skin of the common toad can actually kill people but the important part of it is that it is an incredibly strong pain killer. The puffer fish is extremely poisonous. It puts you in a coma in a near death state. People in Haiti are buried very soon after death and would be in the ground in less than 8 hours. The “dead person” would be dug up and fed datura, a plant with mind blowing after affects.

You Are What You Eat

...You Are What You Eat Linand Blanc Professor Pamella Robinson Principles of Sociology 7/30/2011   Abstract Some may think that carrots and brown rice are healthy eating habits here in the United States. However there are some places in the world including the US where toasted insects, roasted cat and dogs, and even raw monkey brains are a delicacy. Whether you yourself would eat these types of food or not, we know that humans have been consuming cats dogs and yes even monkeys for decades. But my question is why did they find the need to eat these types of meats? Were beef, chicken, fish and pork not enough? Or maybe we’re the ones who don’t know what delicacy eating really is. Maybe we shouldn’t have such a closed mind to eating cats and dogs. Maybe by the end of this week I will be one that becomes an Entomophily.   The Holy Bible goes into great details on what we can and cannot eat. The dietary laws prohibit eating pork, shrimp, and shellfish of any kind, most insects, scavenger birds, and various types of other animals. (Leviticus chapter 11) Although the Bible doesn’t say anything about the domestic animals such as cats and dogs but many religions consider the consumption of these animals to be taboo. In some parts of the word others have resorted to eating felines and k-9’s in desperation during hard times and poverty, and others believe that eating them will bring good luck or good health.

Aggregates/Nuclear Inclusions: Villain or Tragic Hero?

...defining feature of neurodegenerative diseases is the progressive accumulation of nuclear inclusions comprising of irregularly folded protein aggregates. Previously it was thought that protein aggregation is the cause of neurodegeneration as it had been established that neurodegenerative diseases such Huntington’s disease (HD), Parkinson’s disease (PD), Alzheimer’s disease (AD), prion disease, and amyotrophic lateral sclerosis (ALS) all shared a common feature which was these aggregated proteins and the formation of inclusion bodies (Ross and Poirier, 2004). However, recent studies have suggested that protein aggregation may not be the cause of toxicity to cells but that it may in fact be a protective mechanism. The aggregates formed in the above-mentioned diseases can be a consequence of mutations in the sequence of the protein that is related to the disease, increased amounts of a normal protein due to a genetic variation, or even the absence of genetic variations. These may be initiated by environmental stress or aging (Ross and Margolis, 2005). The aggregated proteins can build up and form inclusion bodies, which can be either intracellular or extracellular. There is an ongoing debate about the role of aggregation in the disease process even though one of the most common pathological features of neurodegenerative disorders is inclusion bodies. There is much evidence indicating that aggregation is associated with toxicity in these diseases. On the other hand, there......

Mad Cow

...What are Prions and their role? Prions are the proteins that cause Mad Cow Disease also known as BSE. Prions are an infectious protein. Prions are defined as an proteinaceous infectious particle, the protein is capable of changing the conformation of proteins to match its own and becomes infectious without the use of genetic materials. They can cross between species such as cattle, and sheep. Extreme heats chemical agents can inactivate the proteins. Prions are naturally occurring in the body and are not considered foreign nor do they stimulate the immune system and will not hurt your body, however the disease causing prions contact the normal prions by physical contact and alter the normal prions therefore causing the disease. With Mad Cow Disease The Prions target the specific protein in the cell that is normal called PrPC The role of protein Misfolding in BSE Diseased proteins result from improper folding and therefore the misfolded proteins induces copies of the same protein to also again misfold and increases the disease progress when it is misfolded. The scrapie prion PrPsc contacts and bumps into the normal cellular form PrPc intermediate and shifts the folding process converting them to the misfolded prion (the sheep version of mad cow disease called the PrPsc prion). The process continues over and over again. The body continues producing the normal cell PrPc and the scrapie prion PrPsc continues creating more replications of itself without needing any nucleic...
