Our onboard computer, the brain, is a sterile environment separated from the immune system by the blood-brain barrier (BBB), which is why it has its own resident immune cells, known … Continue Reading New role for white blood cells in the developing brain.
An ever-growing epidemic, obesity is a chronic medical condition where excess body fat has accumulated to the point it may cause a multitude of health disorders. Several studies have also … Continue Reading Visceral fat delivers a signal to the brain that impairs cognition.
The brain is comprised of billions of brain cells, a vast network of synapses and neurons transmitting electronic impulses like many stars in an infinite universe. A crucial support system … Continue Reading New role identified for astrocytes in brain processing.
Stuttering is a neurodevelopmental disorder characterized by pauses and repeated sounds or words, which disrupt the normal flow of speech, causing great embarrassment for some sufferers. For 1 in 4 … Continue Reading Brain cell involved in stuttering identified.
Existing in its own universe, controlling and caring for its host, the human gut contains trillions of bacteria, known as the microbiota, responsible for digesting food and regulating the immune … Continue Reading Gut microbiota protect against neurologic damage from viral infections.
All of our thoughts, bodily functions, memories, and senses are controlled by the central nervous system (CNS), consisting of the brain and spinal cord. Inside the CNS it is the … Continue Reading Textbooks redefined as microglia seen entering the Peripheral Nervous System.
Astrocytes are the most abundant glial cells in the central nervous system (CNS) known to be involved in many roles in the brain including the composition of the blood-brain barrier, … Continue Reading Astrocytes found to have a direct role in brain plasticity.
Acting as natural computers, our brains contain trillions of cells to store memory and control the body’s functions and emotions. Around one in ten of the countless cells in the … Continue Reading Microglia filmed shaping synapses for the first time.
Alzheimer’s disease (AD) is the most common dementia type, with no treatment to slow down the progression of this dehumanizing disease currently available. The mechanisms of AD are poorly understood … Continue Reading Astrocytes linked to Alzheimer’s disease for the first time.
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.
Neurons in an area of the brain known as the hypothalamus control how much an animal eats, however, it is not clear what role the brain’s immune cells, known as … Continue Reading Astrocytes shown to regulate how much we eat.
Pain hypersensitivity can spread to unaffected body regions immediately surrounding the initial insult. Sometimes it can even spread to the opposite site of the body or to large body areas … Continue Reading Pain-initiating function of glial cells identified for the first time.
A significant milestone in the evolution of the mammalian brain is the emergence of the corpus callosum, which is exclusively present in placental mammals. This commissure forms the largest axon … Continue Reading Neuroimaging shows that astrocytes are responsible for joining the 2 halves of the brain together.
Demyelinating diseases, such as multiple sclerosis and leukodystrophy, are characterized by damage to the protective myelin sheath that surrounds the axons of neurons. This demyelination can be caused by an … Continue Reading Cell therapy successfully promotes axon remyelination in an animal model.
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.
