Amyloid precursor protein

Amyloid precursor protein (APP) has many functions and regulations. This protein is involved in neural development. Many may know it for its involvement in the pathology of Alzheimer disease as well as other neurodegenerative diseases. However, APP is a developmental gene. This gene regulates neurons, their differentiation as well as migration. This gene is also involved in neurite outgrowth and the regulation of synaptic function (1). Despite knowledge of these functions, many functions of APP is

Amyloid-β Precursor Protein (APP) is a gene that provides instructions for making a protein called amyloid precursor protein (Andrew, 2009). Amyloid precursor protein is found in several tissues and organs including the brain and the spinal cord--in other words the central nervous system (Andrew, 2009). Some studies suggest that in the brain, APP help direct movement of nerve cells during early development. For instance, APP may be involved in the regulation of synaptogenesis which is the formation

causes Alzheimer’s, but the widely accepted theory is known as the amyloid hypothesis of Alzheimer’s. This hypothesis states that Alzheimer’s is caused by a buildup of plaques in the brain that damage or kill neurons. These plaques form when sticky proteins called amyloid beta clump together. Amyloid beta proteins are produced when amyloid precursor protein (APP) is chopped into multiple pieces by Beta-site Amyloid precursor protein Cleaving Enzyme 1 (BACE1) and an enzyme referred to as gamma-secretase

What is Alzheimer's? It is a disease that affects the central nervous system, digestive system, the neuromuscular system and is generally a disease that is chronic and incurable. 4.7 million people greater than the age of 65 live with the disease each and every day, which is approximately one tenth of the population for those over the age of 65. The most common questions are: what are the risk factors, which vary from person to person, whether or not there are signs and symptoms and has there been

remains unclear to what extent the disorder results from environmental or biological factors (Carr et al., 2006; Hinshaw et al., 2007), and recent researchers believe that biological factors such as genetic inheritance will turn out to be important precursors to the development of ADHD (Durston, 2003). But firm conclusions about any biological basis for ADHD must await further research (Butcher & Hooley, 2014, p. 513). Treatment for ADHD that focuses on controlling behavior with drugs has been promising

Preventative Methods of Alzheimer’s disease Now that the disparity between Alzheimer’s disease prevalence in men and women, as well as the different rates of incidence in different countries has been established, it is now applicable to discuss what can be done to prevent this disease. There are many ways that researchers believe people can use to prevent Alzheimer’s disease. Studies by researchers have found that cannabinoids could stimulate the brain cells and slow the progression of the disease

Introduction: The amyloid precursor protein (APP) is long associated with Alzheimer’s disease (AD). It is a single-pass transmembrane protein and is responsible for producing the neurotoxic Aβ plaque which accumulates within the brain (O’Brien et al. 2011). This accumulation of Aβ is what characterises AD. However, in spite of APP’s detrimental role in the pathogenesis of AD, it has been recently shown that APP can act as a neuroprotective molecule following traumatic brain injury (TBI). Approximately

In 1906, Alzheimer’s disease entered the scientific world. Till this day, it is one of the most studied neurodegenerative diseases. Researchers have come a long way with scientific outcomes on the disease, but unfortunately there is no official cure, or a concise reason on how this disease is generated. The disease has been recognized to being genetic and affecting people in their later years, roughly around their sixtieth year. Alzheimer’s disease affects the person’s memory, language, judgment

woman and found that there were many anomalous masses (amyloid plaques) and intertwined bundles of fiber (neurofibrillary tangles). Scientists today have pinpointed the qualities of Alzheimer’s to be a) tangles in the brain (neurofibrillary tangles), b) plaque in the brain (amyloid plaques), and c) loss of connections among nerve cells. Experts know little about the true causes of AD (Alzheimer’s disease), however they have proposed the amyloid hypothesis to explain how the disease begins. In people

This overview will include background and history of the disease dating back to its discovery by Alois Alzheimer in Germany. It will provide in-depth information on the anatomy and pathophysiology of the disease, specifically on the roles of beta-amyloid plaques and neurofibrillary tangles and on how they progress; what happens as they progress through the brain. Other topics that will be briefly covered include etiology, epidemiology, treatment, and prognosis. Alzheimer’s Disease Background and
