They probably won’t be wearing capes and tights. But will creating new “superchickens” help prevent the next human influenza pandemic? If so, chicken science may have just crossed a road in moving towards genetically engineering chickens to be resistant to the bird flu. In a study published on June 4 in eLife, scientists from Imperial College in London, the University of London, and the University of Edinburgh’s Roslin Institute edited part of the DNA in chicken cells, which then prevented the bird flu virus from using the cells to reproduce themselves.

What do chickens have to do with human flu pandemics? If you are wondering where the virus came from that caused the 1918 influenza pandemic, scientists would give you the bird. The influenza A virus strain that killed more humans in 1918-1919 than all of World War I wasn’t always a human flu virus. It started off as an avian flu virus, just circulating among birds. Avian is another more sciency word for bird. But over time through either mutations or possibly exchanging genetic material with human flu viruses, this bird flu strain acquired the ability to infect and spread among humans. This left humans in deep doo-doo. Their bodies were not ready for this new strain and thus left relatively defenseless.

Thus, another such bird-to-human jump could result in the next influenza pandemic. Plus, the bird flu continues to periodically spread and cause deaths among commercial chicken populations, costing more than a poultry amount of money. As Maryn McKenna reported for National Geographic in 2015, a then recent epidemic of the bird flu cost farms, egg and poultry wholesalers, food service firms, and other sectors that support these industries an estimated $3.3 billion. That’s not simply chicken feed.

Therefore, scientists have been endeavoring to stop the spread of avian flu among birds, with chickens being highest on the pecking order. After all, poultry farms often keep chickens in close, crowded quarters, which can allow bird flu strains to spread quite readily and rapidly among them. Moreover, chickens tend to have more contact with humans than say rufous potoos or Vogelkop superb birds of paradise.

In 2016, scientists made a discovery in this game of chicken with the avian flu virus. They found that a cell protein called ANP32A is different in chickens versus you, assuming that you aren’t a chicken. Avian influenza viruses need to use the ANP32A proteins in chicken cells to reproduce themselves. Thus, no ANP32A protein, no new reproduced viruses. That year scientists also found that the genes responsible for producing ANP32A in chickens were a bit different from the genes responsible for producing ANP32A in you. This difference could result in an ANP32A protein different enough in you so that avian flu viruses cannot use your cells as essentially cheap motels.

All of this led to this latest study that’s eLife or rather that’s in eLife. For the study, the research team showed that, compared to mammalian ANP32 proteins, chicken ANP32 proteins have differences in two amino acids: N129 and D130. These differences then make the mammalian version of the protein unable to interact with and help an enzyme that the influenza A virus (IAV) uses to reproduce itself called IAV polymerase. So if you could somehow change or “edit” the gene that then codes for the ANP32 protein to make the chicken ANP32 protein more like the mammalian, you could potentially keep the IAV polymerase from doing its thing.

Did someone say “edit” the gene? That’s what the CRISPR/Ca9 technique can do. CRISPR (pronounced like “crisper”) stands for Clustered Regularly Interspaced Short Palindromic Repeats, which is the name of a system bacteria have and use to defend themselves. The system can target specific stretches of genes and then edit the DNA with great precision. This allows the bacteria to jumble up the genes of its enemies but also offers scientists tremendous possibilities.

Here’s a TED-Ed primer on CRISPR:

The research team then did a CRISPR chicken experiment. Using the CRISPR/Cas9 gene editing technique on some chicken cells in a culture dish, they removed the genetic sequence that codes for the chicken part of the ANP32 protein that’s different from the mammalian version. Once this was done, the chicken cells could no longer support either mammalian or avian IAV polymerase activity and could resist being infected by the avian IAV.

This opens up the possibility of genetically engineering chickens so that they can’t be infected by avian strains of IAVs. This, in turn, could prevent the bird flu from spreading among flocks. However, before you get too egg-cited, it is no small feat to go from some cells in a test tube to a whole, live chicken (or at least a soon-to-be-live chicken). Chickens are complex systems. It’s not yet clear what else altering these genes may do to chickens. Will such chickens be able to survive? Will this create other problems? Playing around with genes in this way is a relatively new possibility, so you have to be careful about what may happen. In other words, don’t count your superchickens before they’ve hatched.

Nonetheless, this latest step is an important step towards a possible way of reducing the current burden of bird flu and preventing the next influenza pandemic. You don’t have to ask why did chicken science cross this road.

They most likely will not be using capes and leggings. However will producing brand-new “superchickens” aid avoid the next human influenza pandemic? If so, chicken science might have simply crossed a roadway in moving towards genetically engineering chickens to be resistant to the bird influenza. In a research study released on June 4 in eLife, researchers from Imperial College in London, the University of London, and the University of Edinburgh’s Roslin Institute modified part of the DNA in chicken cells, which then avoided the bird influenza infection from utilizing the cells to recreate themselves.

What do chickens involve human influenza pandemics? If you are questioning where the infection originated from that triggered the 1918 influenza pandemic, researchers would offer you the bird. The influenza An infection stress that eliminated more people in 1918-1919 than all of World War I wasn’t constantly a human influenza infection. It started as a bird influenza infection, simply distributing amongst birds. Bird is another more sciency word for bird. However gradually through either anomalies or perhaps exchanging hereditary product with human influenza infections, this bird influenza stress obtained the capability to contaminate and spread out amongst people. This left people in deep doo-doo. Their bodies were not all set for this brand-new stress and hence left fairly unprotected.

Therefore, another such bird-to-human dive might result in the next influenza pandemic. Plus, the bird influenza continues to occasionally spread out and trigger deaths amongst business chicken populations, costing more than a poultry quantity of loan. As Maryn McKenna reported for National Geographic in 2015, a then current epidemic of the bird influenza expense farms, egg and poultry wholesalers, food service companies, and other sectors that support these markets an approximated $3.3 billion. That’s not merely chicken feed.

For that reason, researchers have actually been striving to stop the spread of bird influenza amongst birds, with chickens being greatest on the chain of command. After all, poultry farms typically keep chickens in close, congested quarters, which can enable bird influenza stress to spread out rather easily and quickly amongst them. Furthermore, chickens tend to have more contact with people than state rufous potoos or Vogelkop outstanding birds of paradise.
