Imperial College London researchers discover hair follicles have a unique mechanism to sense touch, releasing neurotransmitters in response. This may shed light on inflammatory skin conditions like eczema. Hair follicles help sense touch by releasing serotonin and histamine, activating sensory nerves. This discovery may provide new insights into inflammatory skin diseases like eczema. Researchers from Imperial College London have uncovered a hidden mechanism within hair follicles that allow us to feel touch. Before this discovery, it was widely believed that touch was sensed solely through nerve endings in the skin and around hair follicles. However, this recent study reveals that cells inside the hair follicles – the entities enveloping the hair strand – can also sense touch in cell cultures. The researchers also found that these hair follicle cells release the neurotransmitters histamine and serotonin in response to touch – findings that might help us in the future to understand histamine’s role in inflammatory skin diseases like eczema. The Unexpected Role of Hair Follicles Lead author of the paper Dr Claire Higgins, from Imperial’s Department of Bioengineering, said: “This is a surprising finding as we don’t yet know why hair follicle cells have this role in processing light touch. Since the follicle contains many sensory nerve endings, we now want to determine if the hair follicle is activating specific types of sensory nerves for an unknown but unique mechanism.” A Touchy Subject We feel touch using several mechanisms: sensory nerve endings in the skin detect touch and send signals to the brain; richly innervated hair follicles detect the movement of hair fibers; and sensory nerves known as C-LTMRs, that are only found in hairy skin, process emotional, or ‘feel-good’ touch. Now, researchers may have uncovered a new process in hair follicles. To carry out the study, the researchers analyzed single-cell RNA sequencing data of human skin and hair follicles and found that hair follicle cells contained a higher percentage of touch-sensitive receptors than equivalent cells in the skin. They established co-cultures of human hair follicle cells and sensory nerves, then mechanically stimulated the hair follicle cells, finding that this led to activation of the adjacent sensory nerves. Neurotransmitters in Touch Perception They then decided to investigate how the hair follicle cells signaled to the sensory nerves. They adapted a technique known as fast scan cyclic voltammetry to analyze cells in culture and found that the hair follicle cells were releasing the neurotransmitters serotonin and histamine in response to touch. When they blocked the receptor for these neurotransmitters on the sensory neurons, the neurons no longer responded to the hair follicle cell stimulation. Similarly, when they blocked synaptic vesicle production by hair follicle cells, they were no longer able to signal to the sensory nerves. They therefore concluded that in response to touch, hair follicle cells release that activate nearby sensory neurons. The researchers also conducted the same experiments with cells from the skin instead of the hair follicle. The cells responded to light touch by releasing histamine, but they didn’t release serotonin. Dr Higgins said: “This is interesting as histamine in the skin contributes to inflammatory skin conditions such as eczema, and it has always been presumed that immune cells release all the histamine. Our work uncovers a new role for skin cells in the release of histamine, with potential applications for eczema research.” Looking Forward The researchers note that the research was performed in cell cultures, and will need to be replicated in living organisms to confirm the findings. The researchers also want to determine if the hair follicle is activating specific types of sensory nerves. Since C-LTMRs are only present within hairy skin, they are interested to see if the hair follicle has a unique mechanism to signal to these nerves that we have yet to uncover.

Researchers found a simple way to reduce sequencing errors in portable DNA sequencers, enabling scientists working outside the lab to study and track microorganisms like the SARS-CoV-2 coronavirus more efficiently. A new barcoding method drastically boosts the accuracy of portable DNA sequencers, enabling near-perfect long-read sequencing for use in diverse research settings. Researchers have found a simple way to eliminate almost all sequencing errors produced by a widely used portable DNA sequencer, potentially enabling scientists working outside the lab to study and track microorganisms like the SARS-CoV-2 coronavirus (the virus that causes COVID-19) more efficiently. Using special molecular tags, the team was able to reduce the five-to-15 percent error rate of Oxford Nanopore Technologies’ MinION device to less than 0.005 percent — even when sequencing many long stretches of DNA at a time. “The MinION has revolutionized the field of genomics by freeing DNA sequencing from the confines of large laboratories,” says Ryan Ziels, an assistant professor of civil engineering at the University of British Columbia and the co-lead author of the study, which was published on January 11, 2021, in Nature Methods. “But until now, researchers haven’t been able to rely on the device in many settings because of its fairly high out-of-the-box error rate.” Genome sequences can reveal a great deal about an organism, including its identity, its ancestry, and its strengths and vulnerabilities. Scientists use this information to better understand the microbes living in a particular environment, as well as to develop diagnostic tools and treatments. But without accurate portable DNA sequencers, crucial genetic details could be missed when research is conducted out in the field or in smaller laboratories. Barcoding Breakthrough Enhances Accuracy So Ziels and his collaborators at Aalborg University created a unique barcoding system that can make long-read DNA sequencing platforms like the MinION over 1000 times more accurate. After tagging the target molecules with these barcodes, researchers proceed as they usually would — amplifying, or making multiple copies of, the tagged molecules using the standard PCR technique and sequencing the resulting DNA. The researchers can then use the barcodes to easily identify and group relevant DNA fragments in the sequencing data, ultimately producing near-perfect sequences from fragments that are up to 10 times longer than conventional technologies can process. Longer stretches of DNA allow the detection of even slight genetic variations and the assembly of genomes in high resolution. Broad Applications Across Scientific Fields “A beautiful thing about this method is that it is applicable to any gene of interest that can be amplified,” says Ziels, whose team has made the code and protocol for processing the sequencing data available through open-source repositories. “This means that it can be very useful in any field where the combination of high-accuracy and long-range genomic information is valuable, such as cancer research, plant research, human genetics, and microbiome science.” Ziels is currently collaborating with Metro Vancouver to develop an expanded version of the method that permits the near-real-time detection of microorganisms in water and wastewater. With an accurate picture of the microorganisms present in their water systems, says Ziels, communities may be able to improve their public health strategies and treatment technologies — and better control the spread of harmful microorganisms like SARS-CoV-2.

Introns are non-coding regions of DNA found within genes of eukaryotic organisms. They are transcribed into RNA but are later removed by a process called splicing before the final mRNA is formed. Introns play a key role in the regulation of gene expression and are thought to have evolved as a way to increase the diversity and complexity of proteins that can be produced from a single gene. UCSC researchers suggest that introns, a source of molecular complexity unique to eukaryotes, primarily originate from introners. The origins of introns, segments of non-coding DNA that must be removed from genetic code before protein synthesis, are one of the most enduring mysteries in biology. Introns are a universal feature of eukaryotic genomes, found in all animals, plants, fungi, and protists, but not in prokaryotic genomes, such as those of bacteria. Despite their ubiquity, there is significant variation in the number of introns found in different species’ genomes, even among closely related species. This has made understanding the origins and evolution of introns a long-standing, fundamental mystery in biology. Now, a new study led by scientists at the University of California, Santa Cruz and published in the journal Proceedings of the National Academy of Sciences (PNAS) points to introners, one of several proposed mechanisms for the creation of introns discovered in 2009, as an explanation for the origins of most introns across species. The researchers believe that introners are the only likely explanation for intron burst events, in which thousands of introns show up in a genome seemingly all at once, and they find evidence of this in species across the tree of life. “[This study] provides a plausible explanation for the vast majority of origins of introns,” said Russell Corbett-Detig, associate professor of biomolecular engineering and senior author on the study. “There are other mechanisms out there, but this is the only one that I know of that could generate thousands and thousands of introns all at once in the genome. If true, this suggests that we’ve uncovered a core process driving something that’s really special about eukaryotic genomes – we have these introns, we have genomic complexity.” Introns are important because they allow for alternative splicing, which in turn allows one gene to code for multiple transcripts and therefore serve multiple complex cellular functions. Introns can also affect gene expression, the rate at which genes get turned on to make proteins and other non-coding RNA. Introns ultimately have a neutral to slightly negative effect on the species they exist in because when the splicing of introns is not carried out correctly, the gene they live in can be harmed and even die. Such missed splicing instances are the cause of some cancers. Corbett-Detig and his colleagues searched the genomes of 3,325 eukaryotic species – all of the species for which we have access to high-quality reference genomes – to find out how common introner-derived introns are, and in which groups of species they are seen most frequently. They found a total of 27,563 introner-derived introns in the genomes of 175 species, meaning evidence of introners could be seen in 5.2% of surveyed species. This evidence was found in species of all types, from animals to single-cell protists – organisms whose last common ancestor lived over 1.7 billion years ago. The diversity of species in which they are found suggests introners are both the fundamental and most widespread source of introns across the tree of life. “It’s diverse – it isn’t like there’s one little chunk of the tree of life that has this going on,” Corbett-Detig said. “You see this in a pretty big range of species, which suggests it’s a pretty general mechanism.” This analysis can only detect evidence of introners going back some millions of years, a relatively short time span when it comes to evolutionary history. It’s likely that intron bursts could have occurred in some species, such as humans, at a time beyond the scope of this analysis – meaning this study probably vastly underestimates the true scope of introner-dervied introns across all eukaryotes. Introners As Genomic Parasites In the ecosystem of the genome, introners can be thought of as a parasite with the goal to survive and replicate themselves. When an introner enters a new organism, that new host has never seen that element before and has no way to defend itself, allowing it to proliferate in a new species. “Everything in evolution is a conflict and these elements, [including introners], are selfish pieces of DNA,” said Landen Gozashti, the paper’s first author who developed the study’s analysis methods as an undergraduate at UCSC and is now a graduate student at Harvard University. “They only want to replicate, and the only reason they don’t want to kill their host is because that kills them.” In being spliced out of the DNA sequence before translation of the gene into proteins occurs, the introners found a way to have less impact on the fitness of the host gene, allowing them to persist through the generations of the host species’ evolution. The researchers found that introners-derived introns seem to splice better than other types of introns, to limit their negative effects on the gene so that both the introner and the host can better survive. More Introners in the Sea While all introners were found across all types of species, results showed that marine organisms were 6.5 times more likely to have introners than land species. The researchers think this is likely due to a phenomenon called horizontal gene transfer, in which genes transfer from one species to a different one, as opposed to the typical vertical transfer via mating and the passing of genes from parent to child. Horizontal gene transfer has already been known to occur more commonly in marine environments, especially between single-cell species with complex ecologies. Introners can travel this way because they belong to a class of genomic elements called transposable elements, which have the ability to move beyond the cell environment in which they live, making them mechanistically well-equipped to travel between species via horizontal gene transfer. As introners transferred from one species to another in marine environments, they vastly expanded their presence across the tree of life. Considering we know that all species evolved from marine organisms, it could have been that land species gained introns from intron bursts far back in their evolutionary history. “If your ancestors were marine organisms, which they all were, there’s a good chance that a lot of your introns are sort of inherited from a similar [introner burst] event back then,” Corbett-Detig said. “This might have been very important in our evolutionary past.” More introners were also found across fungal species, which are also known to have higher rates of horizontal gene transfer, further supporting the idea that this phenomenon drives introner gain. In future research, Corbett-Detig plans to look for proof of horizontal gene transfer in the form of nearly identical introners in two different species. He has set up data mining pipelines so that as the global community of genomics researchers contributes new species’ genomes to data repositories, his algorithm will search each new genome’s introners and compare it to all of the known introners to look for similarities. Understanding How Complexity Evolves This study presents a challenge to one of the overarching theories of genome evolution as to what drives genomic complexity in eukaryotes. The theory also posits that at a point in evolution, many species had low effective population sizes, meaning very few organisms in a species were producing offspring to create their next generation. This allowed elements known to have slightly negative effects on the population to accumulate in the genome. Following this theory, introners, which are neutral to slightly deleterious, would be seen more commonly in populations with lower effective populations – but the researchers found the opposite. For example, they found that Symbiodinium, a protist known to have a much higher effective population size than humans, land plants, and other invertebrates, is the species that seems to be gaining the most introns of those surveyed. But this research points toward complexity arising not from an adaptation created by the genome itself but as a response to conflict caused by the invading transposable element, the introner, as it tries to proliferate. As introners and other elements struggle to survive and persist, this conflict drives genome complexity. Introners and Gene Expression The neutral to negative effects of introns is also evidenced by their effect on gene expression. When comparing genes with introners inserted into them to genes without, those that do have introners had a lower overall expression level, meaning they are turned on less often to perform functions in the body. The researchers believe that introners are not necessarily directly causing this lower expression, but that genes that are expressed less have a higher tolerance for an element that may be affecting them negatively because they matter less for the species’ survival. Meanwhile, genes that are highly expressed and may be coding for key functions in the body likely can’t tolerate the introduction of new introns that could cause them to perform their task less effectively. Corbett-Detig’s ongoing research on this topic also involves looking at direct evidence of how the appearance of introns in a genome affects individuals within a species. He has identified several species that are experiencing ongoing intron bursts and is looking at the effect of introners on the DNA and RNA of the cell, and how this affects the species’ evolutionary fitness.
