Exposure to ultrafine particles from traffic: Altering genes and wreaking havoc on the sense of smell, a new study hilariously reveals!
Now, before you get your knickers in a twist, let’s address the elephant in the room. Particle emissions from road traffic have been regulated in the EU for decades. But guess what, folks? Those sneaky ultrafine particles, with a diameter less than a measly 100 nanometres, have been flying under the radar, freely circulating in the air you breathe, and partying it up without any monitoring or restrictions. Talk about rule-breakers!
But why should you even care about these microscopic troublemakers, you may ask? Well, hold onto your cowboy hats, because the human olfactory mucosa is a tissue that resides front and center, directly exposed to the environment and in good old-fashioned contact with the brain! Now you may be wondering, “What wild signaling pathways are these little particles using to wreak havoc in our delicate brains?” Fear not, my friends; we are about to explore these mysterious catacombs of smelly secrets.
We must take a moment to acknowledge the brave souls who participated in this study. Yes, volunteers willingly offered up their olfactory mucosa cells, collected with the help of Kuopio University Hospital. This multidisciplinary collaboration combined the powers of clinical medicine, gene research, molecular biology, environmental toxicology, and (wait for it) aerosol physics! Picture a superhero team with lab coats, goggles, and smoke machines—except without the smoke, because, you know, we’re here to study pollution… or are we?
Effects of Traffic Pollution on Our Inflamed Noses and Xenophobic Metabolism
Now let me enlighten you about the stars of the show: the particle samples collected by VTT Technical Research Centre of Finland. These samples were meticulously analyzed and characterized by the clever folks at VTT and Tampere University. They managed to secure these samples from the exhausts of a heavy-duty-engine vehicle—at least they had their fun, right?—running on paraffinic renewable diesel and a regular fossil diesel. Oh, but they didn’t stop there! They even concocted a third sample, a delightful blend of the same renewable diesel and cleaner engine technology that complies with the Euro 6d-temp standard. It’s like a pollution party with a twist!
Now, here comes the punchline: all these emissions contained ultrafine particles! But wait, there’s more—both renewable and fossil diesel emissions were also found to contain a generous amount of polycyclic aromatic hydrocarbons (PAHs) and reactive nitrogen compounds. Just when you thought the party couldn’t get any crazier! But hold on tight, because renewable diesel, when combined with cleaner engine technology, managed to produce a mere whisper of emissions. Can you believe it? It’s almost like the engine is telling the pollution, “Shh, we’re trying to keep this party a secret!”
But what does all this mean for our fragile, unsuspecting noses? Brace yourselves, because exposure to these ultrafine particles led to a whirlwind of chaos in our olfactory mucosa cells. And if that wasn’t crazy enough, different fuels and engines caused different adverse effects! In this fascinating tale of molecular-level madness, researchers discovered countless systems that regulate cell function have gone haywire. Picture a bunch of scientists in lab coats, scratching their heads, because they just can’t believe what they’re seeing. Who knew pollution could be so hilariously unpredictable?
These mischievous emissions from both renewable and fossil diesel have the audacity to alter the expression of genes associated with inflammatory response, xenobiotic metabolism, olfactory signaling, and the integrity of the olfactory mucosa. But here’s the twist: renewable diesel causes significantly fewer adverse effects compared to the good old-fashioned fossil diesel. In fact, emissions from renewable diesel combined with cleaner engine technology caused such minimal alterations in cell function that they might as well have worn a tuxedo and carried a little sign saying, “Sorry for the inconvenience.”
Do these findings ring a (funny) bell? If they do, it’s because they support earlier studies suggesting that PAHs may be the culprit behind all the inflammatory response chaos and xenobiotic metabolism disturbance in human olfactory mucosa cells. Oh, and remember those ultrafine particles? Well, it turns out they may just be the messenger, mediating these laughable adverse effects all the way to our brains via the olfactory pathway. It’s like a comedy show playing inside our heads!
But fear not, fellow pollution enthusiasts, because this study lays the groundwork for potential measures to mitigate and prevent these toxicological hazards. And guess what? This study is part of the TUBE project, a hilarious endeavor funded by the Horizon 2020 programme of the European Union. It’s like the EU decided to produce its own comedy show, except instead of watching it at home, you get to experience the effects of pollution firsthand. Truly groundbreaking!
This study has also hilariously received funding from the Kuopio Area Respiratory Foundation, the Finnish Brain Foundation, Yrjö Jahnsson Foundation, and Päivikki and Sakari Sohlberg Foundation. It’s like they’re saying, “We appreciate the chaos you bring, pollution. Here’s some funding to keep the laughs going!”
