Alzheimer’s disease (AD) is characterized by cognitive decline, alteration of synaptic transmission, and neuronal death brought on by accumulation of neurofibrillary tangles in neurons and amyloid beta in the brain. … Continue Reading Study shows that vesicles appear to also contribute to Alzheimer’s disease.
Synaptic mitochondria are thought to be critical in supporting neuronal energy requirements at the synapse, and bioenergetic failure at the synapse may impair neural transmission and contribute to neurodegeneration. However, … Continue Reading Researchers link impaired mitochondria and a loss of ATP to neurodegeneration.
The retina is a layer of tissue in the back of the eye that converts light into nerve impulses. The retina contains small, specialized neurons called bipolar cells that transmit … Continue Reading Researchers discover previously uncharted part of the eye.
Painful insulin injections could become a thing of the past for the millions of Americans who suffer from diabetes, thanks to a new invention from researchers at the University of … Continue Reading World’s first smart insulin patch could replace painful injections for diabetes.
Depression affects an estimated 350 million people worldwide and poses a major public health challenge, according to the World Health Organization. Researchers have discovered an unconventional way that serotonin is … Continue Reading New source of serotonin in the brain found and the effects on SSRI’s identified.
Brain levels of the lipid ceramide are high in Alzheimer’s disease, and now scientists have found increased levels of an antibody to the lipid in their disease model. While some … Continue Reading New study provides more proof that Alzheimer’s is an autoimmune disease.
The human body consists of almost 100 billion neurons that contain synapses, point-to-point contacts for information transfer. Every function, feeling and action depends on the ability of synapses within neurons … Continue Reading New insights into the regulation of neuroplasticity.
While neurons rapidly propagate information in their interior via electrical signals, they communicate with each other at special contact points known as the synapses. Chemical messenger substances, the neurotransmitters, are … Continue Reading Scientists identify proteins responsible for synapse-vesicle fusion.
