Information in the form of chemicals passes from one neuron to another through these contact points.</p>&#13; &#13; <p> ֱ̽map of the 3016 neurons that make up the larva of the fruit fly<em> Drosophila </em><em>melanogaster</em>’s brain, and the detailed circuitry of neural pathways within it, is known as a ‘connectome’.</p>&#13; &#13; <p>This is the largest complete brain connectome ever to have been mapped. It is a huge advance on previous work to map very simple brain structures including the roundworm <em>C. elegans</em>, which only has several hundred neurons.</p>&#13; &#13; <p>Imaging entire brains has until recently been extremely challenging. Now, technological advances allow scientists to image the entire brain of the fruit fly larvae relatively quickly using electron microscopy, and reconstruct the brain circuits from the resulting data.</p>&#13; &#13; <p> ֱ̽fruit fly larva has similar brain structures to the adult fruit fly and larger insects, and has a rich behavioural repertoire, including learning and action-selection.</p>&#13; &#13; <p>“ ֱ̽way the brain circuit is structured influences the computations the brain can do. But, up until this point, we haven’t seen the structure of any brain except in very simple organisms,” said Professor Marta Zlatic at the ֱ̽ of Cambridge’s Department of Zoology and the Medical Research Council Laboratory of Molecular Biology (MRC LMB).</p>&#13; &#13; <p>Zlatic led the research together with Professor Albert Cardona at the ֱ̽ of Cambridge’s Department of Physiology, Development and Neuroscience and the MRC LMB, and Dr Michael Winding at the ֱ̽ of Cambridge’s Department of Zoology. ֱ̽study, which also involved collaborators from both the UK and the US, is <a href="https://www.science.org/doi/10.1126/science.add9330">published today</a> in the journal <em>Science</em>.</p>&#13; &#13; <p>She added: “Until now, the actual circuit patterns involved in most brain computations have been unknown. Now we can start gaining a mechanistic understanding of how the brain works.”</p>&#13; &#13; <p>Current technology is not yet advanced enough to map the connectome of more complex animals such as large mammals. But because all brains involve networks of interconnected neurons, the researchers say that their new map will be a lasting reference for future studies of brain function in other animals.</p>&#13; &#13; <p>“All brains of all species have to perform many complex behaviours: for example they all need to process sensory information, learn, choose food, and navigate their environment. In the same way that genes are conserved across the animal kingdom, I think that the basic circuit patterns that drive these fundamental behaviours will also be conserved,” said Zlatic.</p>&#13; &#13; <p>To build a picture of the fruit fly larva connectome, the team used thousands of slices of the larva’s brain imaged with a high-resolution electron microscope, to reconstruct a map of the fly’s brain - and painstakingly annotated the connections between neurons. As well as mapping the 3016 neurons, they mapped an incredible 548,000 synapses.</p>&#13; &#13; <p> ֱ̽researchers also developed computational tools to identify likely pathways of information flow and different types of circuit patterns in the insect’s brain. They found that some of the structural features are similar to state-of-the-art deep learning architecture.</p>&#13; &#13; <p>“ ֱ̽most challenging aspect of this work was understanding and interpreting what we saw. We were faced with a complex neural circuit with lots of structure. In collaboration with Professor Priebe and Professor Vogestein’s groups at Johns Hopkins ֱ̽, we developed computational tools to predict the relevant behaviours from the structures. By comparing this biological system, we can potentially also inspire better artificial networks,” said Zlatic.</p>&#13; &#13; <p>“This is an exciting and significant body of work by colleagues at the MRC Laboratory of Molecular Biology and others,” said Jo Latimer, Head of Neurosciences and Mental Health at the Medical Research Council.</p>&#13; &#13; <p>She added: “Not only have they mapped every single neuron in the insect’s brain, but they’ve also worked out how each neuron is connected. This is a big step forward in addressing key questions about how the brain works, particularly how signals move through the neurons and synapses leading to behaviour, and this detailed understanding may lead to therapeutic interventions in the future.”</p>&#13; &#13; <p> ֱ̽next step is to delve deeper to understand, for example, the brain circuitry required for specific behavioural functions, such as learning and decision making, and to look at activity in the whole connectome while the insect is doing things.</p>&#13; &#13; <p><em>Adapted from a press release by the Medical Research Council</em></p>&#13; &#13; <h3>Reference</h3>&#13; &#13; <p><em>Winding, M et al: ‘<a href="https://www.science.org/doi/10.1126/science.add9330"> ֱ̽connectome of an insect brain</a>.’ Science, 10 March 2023.

Most people manage to clear the infection themselves, however – only around one in 10 to 20 people will go on to develop the disease.</p>&#13; &#13; <p>Professor Lalita Ramakrishnan and colleagues from the ֱ̽ of Cambridge and the Medical Research Council Laboratory of Molecular Biology, Cambridge, are interested in what makes some people susceptible to TB while others appear to be protected. She uses zebrafish to model human disease as it is relatively easy to manipulate zebrafish’s genetics, and their immune systems share many similarities with those of humans.</p>&#13; &#13; <p>During their research, her team had previously found that zebrafish with mutations that impaired the digestion of proteins by lysosomes became more susceptible to TB. Lysosomes are components of our cells that break down unwanted materials, including proteins and fats, using enzymes. When a mutation affects the production of these enzymes, it can lead to a build-up of toxic materials.</p>&#13; &#13; <p>One type of cell that is vulnerable to this build-up is the macrophage, a type of immune cell that ‘eats’ toxic material, including bacteria and waste products. In lysosomal disorders, the macrophages become enlarged because of accumulation of undigested material in their lysosomes and move slowly, hampering their ability to fight infection.</p>&#13; &#13; <p>Professor Ramakrishnan said: “Macrophages need to move quickly to attack invading bacteria and viruses. Their name means ‘big eater’, and this is exactly what they do. But with lysosomal disorders, they’re unable to break down the food they eat, which makes them bloated and sluggish, unable to perform their duties.”</p>&#13; &#13; <p>However, when Ramakrishnan and colleagues modelled a lysosomal storage disease known as Gaucher disease, they found something very unexpected: TB resistance rather than susceptibility.</p>&#13; &#13; <p>Gaucher disease is a rare disease, affecting around one in 40,000 to 60,000 births in the general population, but rates are significantly higher among Ashkenazi Jews – around one in 800 births. In most cases, the disease can be relatively mild – with symptoms including enlarged spleen and liver, and anaemia – and around two-thirds of people carrying two copies of the most common genetic variant are unaware they are carriers.</p>&#13; &#13; <p>When the researchers genetically engineered zebrafish with genetic variants causing Gaucher disease that are common among Ashkenazi Jews, as anticipated their macrophages became enlarged and unable to break down the toxic materials, in this case an unusual type of fat (called sphingolipids) rather than protein. But when the team exposed the fish to TB, they discovered unexpectedly that the fish were resistant to infection, not susceptible.</p>&#13; &#13; <p> ֱ̽reason for this resistance to infection was because of the fatty chemical that accumulates within the macrophages in Gaucher disease, called glucosylsphingosine. Glucosylsphingosine was found to act as a detergent-like microbicide that kills TB mycobacteria within minutes by disrupting their cell walls.</p>&#13; &#13; <p>Professor Ramakrishnan added: “We’d unknowingly landed in a debate that’s been going on in human genetics for decades: are Ashkenazi Jews – who we know are at a much greater risk of Gaucher disease – somehow less likely to get TB infection? ֱ̽answer appears to be yes.”</p>&#13; &#13; <p> ֱ̽Ashkenazi Jewish diaspora has experienced centuries of persecution, often forced to live in ghettos and migrate from country to country. They would almost certainly have been exposed to TB, which spreads more widely among poorer living conditions and densely-populated urban areas.</p>&#13; &#13; <p>Although this genetic mutation is associated with Gaucher disease, the fact that it makes people more resistant to TB would likely have outweighed the potential fitness cost of Gaucher disease. This would have increased the likelihood of affected individuals passing on their genes to future generations and therefore spread the mutation within the population. A similar phenomenon is seen among some individuals who carry genetic variants that protect them from malaria but, when more than one copy is present, cause harmful anaemia or even sickle cell disease.</p>&#13; &#13; <p>Unlike the example of sickle cell anaemia, however, only individuals who carry two copies of the Gaucher genetic variant – one from each parent – are likely to be protected against TB. That’s because the one ‘healthy’ gene generates enough of the enzyme to clear the macrophages of their accumulating material – and hence gets rid of the antimicrobial substrate.</p>&#13; &#13; <p>Professor Timothy Cox from the ֱ̽ of Cambridge, a co-author on the paper, added: “Our discovery may provide clues to possible new treatments for TB. Drugs that mimic the effects of Gaucher disease – specifically the build-up of glucosylsphingosine – might offer antimicrobial effects against TB.”</p>&#13; &#13; <p>Several such drugs have already been designed by Professor Hans Aerts from Leiden ֱ̽, another co-author on the paper. Because these drugs would only need to be administered for a relatively short amount of time, any side-effects should be limited and temporary.</p>&#13; &#13; <p> ֱ̽research was funded by Wellcome, Gates Cambridge and the National Institute for Health and Care Research Cambridge Biomedical Research Centre. </p>&#13; &#13; <p><em><strong>Reference</strong><br />&#13; Fan, J et al. <a href="https://www.pnas.org/doi/full/10.1073/pnas.2217673120">Gaucher Disease Protects Against Tuberculosis.</a> PNAS; 6 Feb 2023; DOI: 10.1073/pnas.2217673120</em></p>&#13; </div></div></div><div class="field field-name-field-content-summary field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><p><p>Scientists may have solved the question of why Ashkenazi Jews are significantly more susceptible to a rare genetic disorder known as Gaucher disease – and the answer may help settle the debate about whether they are less susceptible to tuberculosis (TB).</p>&#13; </p></div></div></div><div class="field field-name-field-content-quote field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even">We’d unknowingly landed in a debate that’s been going on in human genetics for decades: are Ashkenazi Jews somehow less likely to get TB infection? ֱ̽answer appears to be yes.</div></div></div><div class="field field-name-field-content-quote-name field-type-text field-label-hidden"><div class="field-items"><div class="field-item even">Lalita Ramkrishnan</div></div></div><div class="field field-name-field-image-credit field-type-link-field field-label-hidden"><div class="field-items"><div class="field-item even"><a href="https://www.gettyimages.co.uk/detail/photo/grandfather-helping-little-boy-to-wash-his-hands-at-royalty-free-image/1384288207" target="_blank">halbergman (Getty Images)</a></div></div></div><div class="field field-name-field-image-desctiprion field-type-text field-label-hidden"><div class="field-items"><div class="field-item even">Grandfather Helping Little Boy to Wash His Hands at Passover Seder with Family - stock photo</div></div></div><div class="field field-name-field-cc-attribute-text field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even"><p><a href="http://creativecommons.org/licenses/by/4.0/" rel="license"><img alt="Creative Commons License" src="https://i.creativecommons.org/l/by/4.0/88x31.png" style="border-width:0" /></a><br />&#13; ֱ̽text in this work is licensed under a <a href="https://creativecommons.org/licenses/by/4.0/">Creative Commons Attribution 4.0 International License</a>.
