Oh, the COVID-19 pandemic, that little global hiccup, really showed us we need to up our game in the “making tiny human parts” department. For the past three years, scientists have been on a crafting spree, churning out all sorts of respiratory and pulmonary models like they’re going out of style. We’re talking 3D models that are probably more detailed than my apartment, organoids that sound like they should be in a sci-fi movie, lung-on-a-chip (because who doesn’t want their lungs on a chip?), and slices of lung that are precision-cut like a gourmet meal.

These fancy models are not just for show; they’re like the Swiss Army knives for studying our uninvited guest, SARS-CoV-2, and its virus buddies. But wait, there’s more! They’re also perfect for taking a closer look at lung party poopers like CF, chronic obstructive pulmonary disease, and asthma. Because, you know, understanding how a virus crashes the lung party might just help us crash the virus’s party.

And just when you thought it couldn’t get any cooler, scientists are planning to add more bells and whistles to these models. We’re talking about throwing in some immune cells for a good fight, mixing in some humoral immune components for that extra punch, and even combining organs in microfluidic organ-on-chip devices because, why not? It’s like building the ultimate science project that could save lives. And let’s not forget about making everything standardized and harmonized for drug and vaccine testing. Because nothing says “fun” like making sure your lung-on-a-chip plays nice with others in high throughput testing.

So, hats off to the researchers turning their craft into an art form. Who knew that the key to fighting a pandemic would involve so much creativity? Here’s to hoping these mini organs and slices can help us find the off switch for COVID-19 and its future friends.
