Viruses have evolved to be highly effective vehicles for delivering genes into cells, with these vectors becoming critical in delivering genes to treat disease or label neurons. As viral vectors … Continue Reading Novel viral vectors deliver useful cargo to neurons throughout the brain and body.
During brain development, the formation of neuronal synapses at the right time, the right place, and the right strength are crucial to the ongoing function of the brain throughout life. … Continue Reading Astrocytes regulate the formation of synapses in neurodevelopment.
The brain consists of two major types of cells, namely neurons and glial cells, with the immune-based glial cells providing support and protection for neurons in the central and peripheral … Continue Reading Study identifies previously unknown role of microglia in neurodevelopment.
Neurodegeneration in Alzheimer’s disease is thought to be caused by the abnormal behavior of amyloid-beta molecules, which are known to gather into tough fibril-like structures called amyloid plaques within patients’ … Continue Reading Human amyloid-beta shown to act as a powerful antibiotic in the brains of animal models.
It is known that repeated cocaine-use results in the development of behavioural sensitization, accompanied by a decrease in excitatory synaptic strength in the nucleus accumbens (NAc). Furthermore, glial cells in … Continue Reading Microglia-based mechanism that reduces effect of cocaine on the brain identified.
The human genome is composed of 20,000 genes and as of today, 3,200 of these genes are known to cause diseases, of which 1,700 are associated with ‘recessive’ diseases. Recessive … Continue Reading Researchers identify a previously unknown neurogenetic recessive disease.
