First case of autoimmune encephalitis in a non-human species

First case of autoimmune encephalitis in a non-human species | Salud Publica | Scoop.it

Knut the polar bear may have met an early end but he wasn’t forgotten. The cute polar bear cub born at Berlin Zoo in 2006 and controversially reared by zookeepers, drowned as an adult after experiencing epileptic seizures. Now, the condition responsible for his death has been identified.


The cause of the seizures was unknown since no bacteria, virus or parasite could be found to explain the underlying brain inflammation. The mystery was finally solved by Harald Pruess from the German Centre for Neurodegenerative Diseases in Berlin and his team, who normally study dementia in people.


They analysed samples of Knut’s cerebrospinal fluid, which bathes the brain and spinal cord, and found high levels of an antibody known to attack a glutamate receptor in the brain. In humans, this is a sign of a disease called autoimmune encephalitis. Knut’s case is the first ever reported in a non-human.

he numbers don't lie -- mobile health is thriving. At a time when more adults than ever before use their smartphones to get health information, why are many dentists still not incorporating apps in their practice?According to a 2015 Pew research report, almost two-thirds of Americans own a smartphone, up from about one-third in 2011. The report also found 62% of people used their smartphone as an access point to get information about a health condition.

Why we’re smarter than chickens: Brain-specific exon skipping might be partly to blame

Why we’re smarter than chickens: Brain-specific exon skipping might be partly to blame | Salud Publica | Scoop.it

Toronto researchers have discovered that a single molecular event in our cells could hold the key to how we evolved to become the smartest animal on the planet. Benjamin Blencowe, a professor in the University of Toronto’s Donnelly Centre and Banbury Chair in Medical Research, and his team have uncovered how a small change in a protein called PTBP1 can spur the creation of neurons – cells that make the brain – that could have fuelled the evolution of mammalian brains to become the largest and most complex among vertebrates. The study is published in the August 20 issue of Science (http://www.sciencemag.org/lookup/doi/10.1126/science.aaa8381).

Brain size and complexity vary enormously across vertebrates, but it is not clear how these differences came about. Humans and frogs, for example, have been evolving separately for 350 million years and have very different brain abilities. Yet scientists have shown that they use a remarkably similar repertoire of genes to build organs in the body. So how is it that a similar number of genes, that are also switched on or off in similar ways in diverse vertebrate species, generate a vast range of organ size and complexity?

The key lays in the process that Blencowe’s group studies, known as alternative splicing (AS), whereby gene products are assembled into proteins, which are the building blocks of life. During AS, gene fragments – called exons – are shuffled to make different protein shapes. It’s like LEGO, where some fragments can be missing from the final protein shape.

AS enables cells to make more than one protein from a single gene, so that the total number of different proteins in a cell greatly surpasses the number of available genes. A cell’s ability to regulate protein diversity at any given time reflects its ability to take on different roles in the body. Blencowe’s previous work showed that AS prevalence increases with vertebrate complexity. So although the genes that make bodies of vertebrates might be similar, the proteins they give rise to are far more diverse in animals such as mammals, than in birds and frogs.

And nowhere is AS more widespread than in the brain. “We wanted to see if AS could drive morphological differences in the brains of different vertebrate species,” says Serge Gueroussov, a graduate student in Blencowe’s lab who is the lead author of the study. Gueroussov previously helped identify PTBP1 as a protein that takes on another form in mammals, in addition to the one common to all vertebrates. The second form of mammalian PTBP1 is shorter because a small fragment is omitted during AS and does not make it into the final protein shape. Could this newly acquired, mammalian version of PTBP1 give clues to how our brains evolved?

PTBP1 is both a target and major regulator of AS. PTBP1’s job in a cell is to stop it from becoming a neuron by holding off AS of hundreds of other gene products. Gueroussov showed that in mammalian cells, the presence of the second, shorter version of PTBP1 unleashes a cascade of AS events, tipping the scales of protein balance so that a cell becomes a neuron. What’s more, when Gueroussov engineered chicken cells to make the shorter, mammalian-like, PTBP1, this triggered AS events that are found in mammals.

“One interesting implication of our work is that this particular switch between the two versions of PTBP1 could have affected the timing of when neurons are made in the embryo in a way that creates differences in morphological complexity and brain size,” says Blencowe, who is also a professor in the Department of Molecular Genetics. As scientists continue to sift through countless molecular events occurring in our cells, they’ll keep finding clues as to how our bodies and minds came to be.


“This is the tip of an iceberg in terms of the full repertoire of AS changes that likely have contributed major roles in driving evolutionary differences,” says Blencowe.
