Researchers on the College of Michigan have tapped the common-or-garden banana as their inspiration for a current trial of a brand new option to combat the flu.
In a paper revealed Tuesday, they defined that an engineered compound primarily based on a protein present in bananas elevated survival charges of mice with flu in a dramatic approach.
How can bananas assist combat the flu?
They do not assist combat it immediatelyâ€”they simply impressed a brand new breakthrough that would have critical implications.
David Markovitz, M.D., a professor of inside drugs within the division of infectious illnesses at Michigan Medication and one of many authors on the examine, has been working with a group of collaborators for years on antiviral options for the flu, all primarily based on banana vegetation.
This most up-to-date examine, revealed within the Proceedings of the Nationwide Academy of Sciences, discovered that 80% of mice uncovered to a usually deadly type of the flu survived after they had obtained an injection of the protein. This was true even when the injection was given a full 72 hours after publicity to the virus.
The protein, referred to as H84T, relies on banana lectin however engineered within the lab. The researchers consider it could have medical use implications.
“We had been in a position to present that H84T blocks the flexibility of the influenza virus to fuse with constructions termed endosomes within the human cell, a key step in an infection,” defined Markovitz.
Banana lectin in its natural kind, like different lectins, is linked to some unfavourable unwanted effects like inflicting irritation. On this examine, early proof signifies that the engineered protein doesn’t appear to hold the identical unfavourable impacts. In addition they discovered that whereas the mice did develop antibodies to the brand new protein, it didn’t lead to opposed results in mice.

How will it work in the actual world?
The performance of the protein implies that whereas it does bode nicely as a possible choice for preventing the flu, it additionally could also be efficient in opposition to “Ebola, HIV, measles, MERS, a brand new lethal viral sickness that was first reported in Saudi Arabia in 2012, SARS and all different coronaviruses examined,” in accordance with a information launch from the college.
The protein injection additionally appears to work when the present normal therapy, Tamiflu, fails: “We have additionally proven that there could also be a synergistic impact between H84T and Tamiflu,” mentioned Markovitz.
Whereas the present influence of this new breakthrough has solely been proven in mice, the group hopes to do extra analysis in regard to using the compound in people.
Whereas we won’t simply flip to a banana a day to maintain the flu away, there are some tried-and-true habits you need to use to assist make flu season much less painful. And if you happen to do get hit with this yr’s pressure, there are some teas you may flip to to make it extra bearable, and a few meals which will assist kick your flu quicker.
