Cowpea Mosaic Virus May Help Cure Cancer!

Not off topic: Tennessee makes Ivermectin sales "over the counter" meds A-OK, once sold exclusively in farm supply stores and on line. Now it's a cancer fighter too! :o Contd below:

This cancer fighter link goes generic so I pasted it from it's start to the last word.

Meet the plant virus that may help cure cancer

SAN DIEGO, Calif. — Not all viruses are bad, and one in particular may have the power to stop cancer. Researchers at the University of California-San Diego are studying how a plant virus called cowpea mosaic virus stops cancer and prevents it from coming back. Their latest research shows that when the virus infects cancerous cells, it signals to the immune system and extends the anti-cancer response toward the tumor.

Cowpea mosaic virus is an infectious plant virus that commonly targets **legumes. For the past seven years, however, study authors have been using animal models to determine its potential as a cancer immunotherapy treatment.

“This study helps validate the cowpea mosaic plant virus nanoparticle as our lead cancer immunotherapy candidate,” Nicole Steinmetz, a professor of nanoengineering at the UC San Diego Jacobs School of Engineering and the director of the Center for NanoImmunoEngineering, in a university release. “Now we have mechanistic data to explain why it is the most potent candidate, which further de-risks it for clinical translation.”

The perfect bait for fighting cancer?
The team has studied the cowpea mosaic virus in the form of nanoparticles. They injected the nanoparticles directly into the tumor to serve as bait for the immune system. Once the lure is set, immune cells detect the viral nanoparticles and send alarms to the rest of the immune system of a foreign invader in the body. While the immune cells build up to fight the virus, they start to eliminate the cancerous cells once they realize cowpea mosaic virus is inside a tumor.

Not only does the virus help get rid of the existing tumor, but Dr. Steinmetz notes that it also triggers a systemic immune response against any future tumors. While not studied in humans yet, they have observed this immune effect in canines and mouse models of various types of cancer. The cowpea mosaic virus is also unique in that it triggers an anti-cancer response that scientists don’t see in other plant viruses or virus-like particles.

“We’ve shown that it works, and now we need to show what makes it so special that it can induce this kind of response,” says lead author Veronique Beiss, a former postdoctoral researcher in Dr. Steinmetz’s lab. “That’s the knowledge gap we’re looking to fill.”

The virus triggers more disease-killing inflammation
To look at anti-tumor efficacy in similar plant viruses, the team compared the cowpea mosaic viruses with two plant viruses from the same family with similar shapes and sizes. The cowpea severe mosaic virus shared a similar RNA sequence and protein makeup. The other plant virus, the tobacco ringspot virus, only had a similar structure.

They then infected a melanoma tumor in mice with three doses of each virus-based nanoparticle immunotherapy given a week apart. Mice receiving the cowpea mosaic virus nanoparticles were more likely to survive and have the smallest tumors than those that did not. The tumor growth stopped about four days after the second dose.

Afterward, the researchers took immune cells from the spleen and lymph nodes from mice. They found that all plant viruses contain a protein shell to activate toll-like receptors that are on the surface of immune cells. However, the cowpea mosaic virus takes an extra step by using its RNA to activate an extra toll-like receptor. Activating additional toll-like receptors leads to more pro-inflammatory proteins called cytokines appearing and strengthening the immune response against cancer.

Another way the cowpea mosaic virus increases the immune response is by extending the cytokine response.

“We don’t see this with the other two plant viruses. The cytokine levels peak quickly, then go down and are gone,” explains Beiss. “This prolonged immune response is another key difference that sets cowpea mosaic virus apart.”

Ivermectin News Flash!🌩

Tennessee Governor Bill Lee has signed SB 2188 that allows Ivermectin, an award-winning antiviral drug, to be available for the treatment of COVID-19 without a prescription in Tennessee.

The state’s Senate overwhelmingly voted 66-20, and the House voted 22-6 in favor of the bill. (Article republished from The bill states that a pharmacist can provide Ivermectin to a patient, who is 18 years of age or older, “pursuant to a valid collaborative pharmacy practice agreement containing a non-patient-specific prescriptive order and standardized procedures developed and executed by one or more authorized prescribers.”

That means that adults can explain their symptoms to the pharmacist, fill out a sheet listing any preexisting conditions and other medications they are taking, and the pharmacist can determine the right dosage.😎 😘
