When Dr. Alois Alzheimer presented his initial findings on Alzheimer disease in 1906, his colleagues were less than impressed. (hudsonalpha.org)
It was first recorded in 1907 by Dr Alois Alzheimer who reported the case of Auguste Deter, a middle-aged woman with dementia and specific changes in her brain. (wellbeing.com.au)
The amyloid hypothesis can be traced to Dr. Alois Alzheimer , a pathologist who first described the disease that would bear his name in 1906. (upr.org)

However, while CpH methylation decreases later in life, this process is accelerated in AD and reactivates the cell cycle in differentiated post-mitotic neurons and triggers apoptosis rather than encouraging proliferation. (epigenie.com)
It is a progressive, irreversible, and incurable neurodegenerative disorder that disrupts the synaptic communication between millions of neurons, resulting in neuronal death and functional loss due to the abnormal accumulation of two naturally occurring proteins, amyloid β (Aβ) and tau. (frontiersin.org)
The tau protein is predominantly found in brain cells (neurons). (brightfocus.org)
The healthy human brain contains tens of billions of neurons, or brain cells, that send messages between different parts of the brain, and from the brain to the muscles and organs of the body. (hudsonalpha.org)

People who develop Alzheimer disease are more likely to have an APOE ε4 allele than people who do not develop the disease. (medscape.com)
however, inheriting an APOE ε4 allele does not mean that a person will definitely develop Alzheimer disease. (medscape.com)
Although a blood test can identify which APOE alleles a person has, it cannot predict who will or will not develop Alzheimer disease. (medscape.com)
For example, having a certain form of apolipoprotein E (APOE) gene increases a person's risk of developing Alzheimer disease and it is also associated with an earlier onset of the disease. (hudsonalpha.org)
It is thought that the apolipoprotein E produced from the e4 allele of the APOE gene may disrupt the transport of a protein called alpha-synuclein into and out of cells. (medlineplus.gov)
APOE is a correlate of phenotypic heterogeneity in Alzheimer disease in a national cohort. (cdc.gov)

Those plaques are often found near areas of cell death in diseased brains. (sciencedaily.com)
It's thought that eating a diet low in fats, cholesterol and sodium may help keep the brain strong enough to prevent some of these cell die-offs and limit the growth of plaques. (nutrivene.com)
The brains of people with the condition contain distinctive plaques between nerve cells, as well as clumps of fibers known as neurofibrillary tangles inside the cells. (medicalnewstoday.com)
These plaques impair synapses so signals cannot pass between brain cells. (wellbeing.com.au)
In the 1980s, scientists showed that these plaques were made of beta-amyloid, a substance that exists in many forms in the brain, from single free-floating molecules to large assemblies that form the sticky plaques reported by Alzheimer. (upr.org)
These plaques disrupt the function of brain cells and their ability to communicate with each other - which may lead to cognitive issues, such as memory loss. (theconversation.com)
This signals that there's a threat to the brain's immune cells, which then come and remove the plaques. (theconversation.com)
beta-amyloid is the main component of neuritic (senile) plaques, which consist of degenerated axonal or dendritic processes, astrocytes, and glial cells around an amyloid core. (msdmanuals.com)

He has published over 600 papers on gene therapy, cell cycle, genetics of cancer, and epidemiology. (newswise.com)

2. Nuclear transfer is a technique used to duplicate genetic material by creating an embryo through the transfer and fusion of a diploid cell in an enucleated female oocyte.2 Cloning has a broader meaning than nuclear transfer as it also involves gene replication and natural or induced embryo splitting (see Annex 1). (who.int)
if it implants and the pregnancy goes to term, the resulting individual will carry the same nuclear genetic material as the donor of the adult somatic cell. (who.int)
However, an animal created through this technique would not be a precise genetic copy of the source of its nuclear DNA because each clone derives a small amount of its DNA from the mitochondria of the egg (which lie outside the nucleus) rather than from the donor of cell nucleus. (who.int)

Here, by characterizing the intracellular diffusion and the three-dimensional lamellipodium structures of fish keratocyte cells, we observe a strong positive correlation between the intracellular diffusion and cell migration speed and, more importantly, discover a switching of cell migration modes with reversible intracellular diffusion variation and lamellipodium structure deformation.
