Richard Pops, Alkermes CEO, provides insight to the enormous market for schizophrenia and depression. Schizophrenia is a severe mental health condition that causes significant disability, and affects 1 in 100 people. Apr. October 28, 2020 05:24 AM Eastern Daylight Time. It suggests immune cells themselves may be producing these inflammatory signals in the brains of people living with schizophrenia,” said Professor Shannon Weickert. In some cases, the person is already symptomatic, and due to being exposed to an extremely traumatic experience, an existing mental health condition becomes exacerbated and symptoms intensify. Schizophrenia is a serious mental disorder in which people interpret reality abnormally. In July 2014, the Schizophrenia Working Group of the Psychiatric Genomics Consortium – including investigators from the Stanley Center – identified more than 100 areas of the human genome that are linked to the disorder. This does not normally happen with most other genes, making C4 a gene of interest. “It’s a clever way nature reuses the same molecules for different jobs.”. The name came from the Greek words “schizo” (split) and “phren” (mind), fueling the myth that people with schizophrenia have split personalities; this is not the case. This discovery shows that specific immune cells are in the brains of some people with schizophrenia in close enough proximity to the neurons to do damage. Learn about some of the benefits and risks, as well as how to choose the best headphones for sleep…, Most people dream 3-6 times per night, although many people will not remember dreaming at all. Using this adapted method to see what role C4 plays in the brains of mice, the researchers found that the gene is key for synaptic pruning – the process by which synapses are streamlined, which normally occurs in late adolescence/early adulthood in humans. Professor Shannon Weickert said immune cells have previously been ignored as they had long been viewed simply as travelers just thought to be passing by, undertaking surveillance work. They aim to find out more about how C4 contributes to synaptic pruning, and to determine whether such pruning may play a role in other neurological conditions. By James Gallagher Health reporter, BBC News. Scientists make schizophrenia breakthrough. Employing new molecular techniques allowed Professor Shannon Weickert and her team to identify the presence of a fourth cell, the macrophage, a type of immune cell in the brain tissue of people with schizophrenia who show high levels of inflammation. “We think this may cause the endothelial cells to extend sticky tentacles, so when the immune cells travel by some are captured. Professor Shannon Weickert is uniquely motivated in her work, with her twin-brother being diagnosed with schizophrenia when he was 17 years old. This is a question that has challenged scientists since the disorder was first identified almost 130 years ago. -AMAZONPOLLY-ONLYWORDS-END- “To find immune cells along the blood brain barrier in increased amounts in people with schizophrenia is an exciting discovery. The illness was first discovered by German psychiatrist Dr. Emile Kraepelin in 1887, though the term “schizophrenia” was not used until 1910, coined by Swiss psychiatrist Paul Eugen Bleuler. “This discovery enriches our understanding of the complement system in brain development and in disease, and we could not have made that leap without the genetics,” says study coauthor Beth Stevens, of the Department of Neurology at Boston Children’s Hospital. What causes schizophrenia? This gene is C4, which is already known to play a key role in the immune system, alerting immune cells to pathogens that need to be destroyed. The largest study of its kind looked at 100,000 people, including 40,000 with a diagnosis of schizophrenia, and found that certain gene "regions" increase the risk of developing the mental health condition. Deconstruction of the schizophrenia “syndrome” is widely endorsed and work is being done to get at the relevant dimensions of the condition to determine how they can be influenced. One in every 100 Australians lives with schizophrenia. NeuRA Media Department +61(0)409225447 or media@neura.edu.au, Katrina Usman +61(0)432760940 or k.usman@neura.edua.au. This article looks at some of the recent theories about…. While the research is in its early days, the findings undoubtedly represent a breakthrough in the understanding of schizophrenia development. To recognise the significance of this discovery Professor Shannon Weickert says you first need to understand most scientists have had a long held belief that immune cells were independent from the brain pathology in psychotic illnesses. In March, when cases of COVID-19 began to overwhelm … What does loneliness look like in the brain? It suggests immune cells themselves may be producing these inflammatory signals in the brains of people living with schizophrenia,” said Professor Shannon Weickert. The team says their findings may explain why schizophrenia tends to develop in late adolescence or early adulthood; excessive synaptic pruning caused by increased C4 activity at this point in time may trigger symptom onset. ... on this new genetic breakthrough. “In this area of science, our dream has been to find disease mechanisms that lead to new kinds of treatments,” says McCarroll.
