Scientists May Have Found a Way to Treat All Cancers… By Accident | SciShow News

to someone you love! [ intro ] People often wonder why there isn’t a cure
for cancer yet. And the answer is usually because “cancer”
isn’t one thing. It’s this big umbrella term for a ton of
different conditions where cells grow out of control. While there are treatments for some types
of cancer, different cancers are, well, different enough that there’s nothing that works for all
of them — no universal cure. But, uh, it turns out there might be? Researchers from Cardiff University in Wales may have found a way to treat all cancers, or at least a whole lot of them. And they just kind of stumbled onto it. The researchers weren’t searching for cancer
therapies. They were looking for ways to fight bacteria
with immune cells called killer T cells. As the name implies, these cells kill things. Specifically, things that aren’t good for
your body. But unlike other immune cells, they don’t target bacteria or viruses directly. Instead, they go around interrogating the
body’s own cells, trying to sniff out ones that might be hiding
pathogens inside them. And when they find an infected cell, they
kill it. But not all killer T cells are the same. There are different types that use slightly
different proteins, called receptors, to check out cells. Often, these receptors are somewhat specific to the invader they’re hunting for. But the researchers were looking for a kind
of T cell that can detect lots of different bacteria. So, they pulled a bunch of killer T cells
from blood samples and tested their infection-spotting abilities. The test the team was using just so happens
to employ a kind of cancer cell that’s easy to infect with bacteria. And a number of different T cells showed promise when the scientists set them loose on these
infected cancer cells. But one was especially ruthless. Unfortunately, in further experiments, it killed all of the cancer cells, not just the ones with bacteria inside them
— so it wasn’t what they were looking for. But it did pique their curiosity. Now, it’s not that weird for a T cell to
kill cancer cells, because T cells don’t just hunt for infections. They are also in charge of keeping cancers
in check. And over the past several years, scientists have started harnessing the power
of these cells to fight cancer. In CAR-T immunotherapy, for example, T cells are removed from a person’s body, genetically programmed with a receptor which
can spot the person’s cancer, and then injected back in to seek and destroy. But we can’t do this for all cancer patients
yet because we don’t have good receptor targets for every type or even subtype of cancer. You know, that whole “cancers aren’t all
the same” bit. But I digress. Point is, it wasn’t super surprising that the researchers
had found a T cell that killed this particular type of cancer. But, before just discarding or shelving them to continue the hunt for bacteria-killing
T cells, they decided to see what happened with some
other cancer types, too. And they worked. Against all of them. Lung cancer, colon cancer, bone cancer, breast
cancer, blood cancer, skin cancer… these T cells killed every kind of cancer
the researchers tried. Not only that, but they left healthy cells
alone. Which is, like, WHOAH. Needless to say, this sparked a new investigation into how
these T cells were doing this. To figure that out, the researchers deleted proteins from the
cancer cells one by one using CRISPR-Cas 9 gene editing. The idea being that, if deleting a protein made the T cells ineffective, then that protein must be involved in how
the cells are spotting cancer. And that led them to a protein called MR1. Now, what’s interesting about that, is MR1 can be found on all your cells, not just cancerous ones. See, it’s thought to be an informant of
sorts for the immune system. It samples molecules from inside the cell and presents them on the outside, where immune cells can take a look. And that’s exactly what these killer T cells
seem to be doing. They have a special receptor that allows them to interact with MR1 proteins and read those samples. They’re not the only T cells that interact with MR1, but they seem to be the only ones we’ve
found so far that can spot all sorts of cancers by doing
so. The researchers were even able to take this
receptor and stick it into T cells from actual cancer
patients. So basically, the same idea as CAR-T therapy, but using this one protein instead of tailoring
the T cells to each patient’s specific cancer. And not only did those engineered T cells
kill samples of the patients’ tumors, they killed cancers from multiple patients. That’s probably because MR1 proteins don’t really differ much between people, so the same receptor can recognize all of
them. this means that instead of having to design
individual therapies for each cancer, doctors might be able to use this one receptor to make T cells that work for everyone. But we shouldn’t pop open the champagne
quite yet. There are still some big unknowns here. Like, the researchers don’t actually know
how the T cells are recognizing MR1. Seriously, the actual wording in the paper
is that this receptor quote “does not recognize MR1 by known mechanisms”. And they don’t know what MR1 is showing
the T cells to alert them that the cell is cancerous — though, presumably it’s unique to cancers and, if not universal, then at least super
common. Most importantly, though: they have yet to try these T cells in actual
human patients. They did test them in mice given human cancers, and the results were promising. But it’s still possible they won’t work
well in a real, live person. We should know fairly soon. The researchers’ current plan is to proceed
cautiously, and if safety tests go well, they’re hopeful human trials could start
in the next few years. On the upside, even if this doesn’t lead
to a quote “cure for cancer”, studying these T cells could help scientists discover new ways to treat a lot of different
cancers. And the team is already on the hunt for other, similar T cells that can kill multiple cancers. And to think — this discovery would never have happened if the researchers didn’t have the good
sense to investigate further when some cells did something funny. Thanks for watching this episode of SciShow

    And what will come of this, one has to wonder as its been said many many times over the years. Bottom line if they can patient it and make it so you pay a lot for it, then it will end up in your local medical industry. Sadly otherwise it will not. Thats just the way big business works. Im not saying I dont like it when such things are stated from a positive perspective, I love the impression such gives, I just also know how it all will work out, because thats just business and money runs the world as they say. Ever wonder why the commercials say we have a pill for this or that, then they state the side effects include ten other problems that will come from taking the pill, many of which are far worse or even deadly. How few ever say hmm is this commercial really saying if your gullible enough to fall for taking this pill, then these other ten problems the pill will bring about will allow far more money to be made from you as you then pay to fix the new problems that the pill caused, and which they surely have another pill for, get it? But that could not be something intentionally designed to be that way could it, or could it. Its kind of like saying oh we can put a man on the moon but we cant make a pill that dont give you ten other problems as it fixes your first problem, see the flawed logic to this that should make it plain as day. But to many sadly its still not.

    So since the 1930s, our government teamed up with 1%er major business owners to put chemicals in everything they can, that cause cancer in us by making our body acidic.
    IE talcom powder was used in all baby and foot and body powder. Johnson and Johnson have been sued BY THE MILLIONS. Yet talcom powder is still put into powder today due to ignorant citizens.
    MAKING YOUR BODY ALKALINE MAKES YOUR BODY IMUNE TO CANCER, WE HAVE KNOW THIS SINCE 1931.

    CANCER is a gigantic business.

    If a cure were to be found tomorrow I suspect it would be suppressed. It may have been already.

    Big Pharma in America pay doctors to prescribe chemotherapy despite it having only a 3% survival rate [living for 5+ years after treatment] So no incentive to try anything else.

    I wonder if all those well-meaning runners in the London Marathon realised that nearly ALL the money they raised eventually found it's way into the coffers of Big Pharma. I suspect not.

    Apart from the Macmillan Nurses, every cancer charity gives it's donations to the pharmaceutical industry to find a "cure" for cancer WHICH CAN BE PATENTED. Thus making "the next Viagra".

    And yet there are dozens of natural “cures” for cancer.

    Bitter apricot kernels and cannabis being the best known but others like even mistletoe and various herbs [Google Harry Hoxsey and Rene Caisse] have been used but is there any research into whether they can combat cancer?

    NO. Because they are natural product and cannot be patented.

    The reason there is "no cure" is in my opinion, is because there would be no more funding and donations. Why keep donating money to a cause that there is already a cure? I honestly believe there is a cure for many diseases including AIDS, Alzheimers, ALS, diabetes, and many more. Without a cure, the government is in complete control of your health. But if there was a cure, the cost would be massive that people couldn't afford medication anyway.
