Sleep may strengthen long-term memories in the immune system

first_imgLinkedIn Studies in humans have shown that long-term increases in memory T cells are associated with deep slow-wave sleep on the nights after vaccination. Taken together, the findings support the view that slow-wave sleep contributes to the formation of long-term memories of abstract, generalized information, which leads to adaptive behavioral and immunological responses. The obvious implication is that sleep deprivation could put your body at risk.“If we didn’t sleep, then the immune system might focus on the wrong parts of the pathogen,” Born says. “For example, many viruses can easily mutate some parts of their proteins to escape from immune responses. If too few antigen-recognizing cells [the cells that present the fragments to T cells] are available, then they might all be needed to fight off the pathogen. In addition to this, there is evidence that the hormones released during sleep benefit the crosstalk between antigen-presenting and antigen-recognizing cells, and some of these important hormones could be lacking without sleep.”Born says that future research should examine what information is selected during sleep for storage in long-term memory, and how this selection is achieved. In the end, this research could have important clinical implications.“In order to design effective vaccines against HIV, malaria, and tuberculosis, which are based on immunological memory, the correct memory model must be available,” Born says. “It is our hope that by comparing the concepts of neuronal and immunological memory, a model of immunological memory can be developed which integrates the available experimental data and serves as a helpful basis for vaccine development.” Share Email More than a century ago, scientists demonstrated that sleep supports the retention of memories of facts and events. Later studies have shown that slow-wave sleep, often referred to as deep sleep, is important for transforming fragile, recently formed memories into stable, long-term memories. Now, in an Opinion article published September 29 in Trends in Neurosciences, part of a special issue on Neuroimmunology, researchers propose that deep sleep may also strengthen immunological memories of previously encountered pathogens.“While it has been known for a long time that sleep supports long-term memory formation in the psychological domain, the idea that long-term memory formation is a function of sleep effective in all organismic systems is in our view entirely new,” says senior author Jan Born of the University of Tuebingen. “We consider our approach toward a unifying concept of biological long-term memory formation, in which sleep plays a critical role, a new development in sleep research and memory research.”The immune system “remembers” an encounter with a bacteria or virus by collecting fragments from the bug to create memory T cells, which last for months or years and help the body recognize a previous infection and quickly respond. These memory T cells appear to abstract “gist information” about the pathogens, as only T cells that store information about the tiniest fragments ever elicit a response. The selection of gist information allows memory T cells to detect new pathogens that are similar, but not identical, to previously encountered bacteria or viruses.center_img Pinterest Share on Facebook Share on Twitterlast_img read more

See The Signs

first_imgThe Suffolk County Historical Society in Riverhead presents a special free artists’ reception on Saturday, January 18, at 1 PM featuring “Urban/Suburban” in the Gish Gallery. The show, which will run through February 29, features street photography by Neil Scholl. It depicts the bustling streets of New York City and rural stills across the North Fork.Scholl is a professor emeritus of New York Institute of Technology, where he taught photography and graphic design. His work has been exhibited along Long Island, including the Montauk Lighthouse Museum and Water Mill Museum.“Though we are primarily a history museum, we do enjoy occasionally incorporating modern artistic themes that evoke nostalgic memories of life in Suffolk County, and Neil Scholl’s street photography work does just that,” said Suffolk County Historical Society’s executive director, Victoria Berger.“His photography, captured with a skillful eye, was curated to conjure memories of some of our favorite roadside ‘landmarks’ of the North Fork, going as far back as the ’60s, juxtaposed against images of similar sites in more concrete settings. The results make you better appreciate the tranquility of our region, while striking a very nostalgic chord for those who may recognize the local landscapes portrayed in his work,” she said. The Suffolk County Historical Society Museum is located at 300 W. Main Street in Riverhead. Learn more at www.suffolkcountyhistoricalsociety.org.nicole@indyeastend.com Sharelast_img read more

PI solicitor helped client who wanted to hide damages from husband

first_imgAn experienced personal injury lawyer has agreed to be struck off after drafting a letter to help a client conceal from her husband the extent of a damages settlement. Geoffrey Hart, a former director with Midlands firm Ward & Rider, had secured damages of £48,000 after costs for his client in 2017. But, during a telephone discussion, the client advised Hart she would be telling her husband the claim settled for £30,000 and asked him to prepare a letter confirming the lower amount.Hart then wrote to state damages were £30,000 and broke down the elements of the claim. He wrote a further letter two weeks later referring to the £30,000 figure.The Solicitors Disciplinary Tribunal heard that the client, who was a family friend of Hart’s wife, had told him she wanted to keep some of her own damages because her husband was controlling and would decide how the money was spent.Hart submitted that he became ‘very emotional’ after learning the client had gone through tragic events in her personal life similar to those he was experiencing at the time, and he acted out of character in drafting the false letter.A clinical psychologist report confirmed that Hart made a mistake while experiencing psychological difficulties and some associated impairment in cognitive processing – namely judgement and reasoning.Hart, a solicitor for 21 years, made no attempt to conceal the relevant letters and upon realising the seriousness of the matter he pressed his employer to recall the letter. He was reported to the SRA by his firm and resigned shortly after. The false letter was not shown to the client’s husband or anyone else.The tribunal heard that Hart also admitted sending an email to his wife, a solicitor, which included personal information about another client who had suffered a personal injury. The email was to provide his wife with a precedent document for her own legal practice.Hart and the SRA agreed on a joint outcome that he be struck off and pay £9,000 costs.last_img read more
