How Body Cells Kill Cancer Cells Video


 

In this video we see a killer T cell of the immune system attacking a cancer cell.

Professor Gillian Griffiths:
“Cells of the immune system protect the body against pathogens. If cells in our bodies are infected by viruses, or become cancerous, then killer cells of the immune system identify and destroy the affected cells. Cytotoxic T cells are very precise and efficient killers. They are able to destroy infected or cancerous cells, without destroying healthy cells surrounding them. The Wellcome Trust funded laboratory of Professor Gillian Griffiths, at the Cambridge Institute for Medical Research, investigates just how this is accomplished. By understanding how this works, we can develop ways to control killer cells. This will allow us to find ways to improve cancer therapies, and ameliorate autoimmune diseases caused when killer cells run amok and attack healthy cells in our bodies.”

Cytotoxic T cells are just 10 microns in length: approximately one-tenth the width of a human hair. These movies are 92 times real time.

The original footage shown was made by Alex Ritter, a PhD student on the NIH-OxCam programme, in the laboratory of Professor Gillian Griffiths at the Cambridge Institute for Medical Research and the Department of Medicine of the Clinical School of the University of Cambridge. The images were acquired using an Andor Revolution spinning disk system with an Olympus microscope. Professor Griffiths is a Wellcome Trust Principal Research Fellow.

Why doesn’t A Woman’s Body Reject Fetus As Alien


An interesting article and one wonders what nature can do ?

Story:

Foetus

Foetus 24 Weeks

Of all the miracles of life, here’s by far the most miraculous of all: Women’s bodies, for the most part, do not attack and destroy the fetus growing inside them.

From an immunologic point of view, the fetus is an alien. Like a germ. Or an organ transplant. And your body is programmed to mount an assault on foreigners. But my fetus is half me, you say. And so, you may suspect—as others have before you—that the “half-me” part signals the body to avoid all-out warfare. This makes emotional sense! But the success of surrogate moms and donor eggs—with women gestating babies produced by the eggs of other women, their bodies accepting the presence of a fetus that is not “half-them”—proves that idea wrong.

So that leads us to the big question: Why does pregnancy even work?

Pregnancy, as Yale School of Medicine’s Harvey Kliman sees it, is a metaphor for marriage. The placenta is controlled by the father’s genes, the embryo by the mother’s. Each side has its own agenda. Yet, the key to a successful union—whether it be mother and fetus, or husband and wife—is compromise. The details of this compromise have always been a mystery, but in the past few years, scientists seem to be edging closer to understanding the specific negotiations that occur deep within the cells of the women’s body that allow the fetus to escape destruction.

For years, doctors have been eyeing T cells, the immune cells that attack and destroy invaders (which should include the fetus). A few years ago, a team of researchers at NYU School of Medicine, lead by Adrian Erlebacher in the department of pathology, discovered something that had never been seen before: In pregnant mice, even when the T cells were experimentally nudged into attack mode, they did not bite.

These early studies prompted the NYU team to dig deeper, trying to figure out the chain of events that would stop the T-cell attack. They eyed a certain family of genes that, when working properly, recruit and send T cells marching toward invaders. But in the pregnant mouse, the genes were silenced in the decidua—the tissue surrounding the fetus and the placenta—by a chemical that attached to the genes’ proteins, altering the way the genes look and therefore how they act. With this physical change, the genes can no longer communicate “attack!” to the T cells.

The upshot: In a pregnant mouse, at least, the genes can’t do their job, which means that the cascade of events that would lead to an immune assault on the fetus never happens.

All purpose Cancer Vaccine Developed.


There have been so many claims over the years that I would take this with a pinch of salt.

The Human Body -- Cancer

A vaccine that can train cancer patients‘ own bodies to seek out and destroy tumour cells has been developed by scientists.

The therapy, which targets a molecule found in 90 per cent of all cancers, could provide a universal injection that allows patients’ immune systems to fight off common cancers including breast and prostate cancer.

Preliminary results from early clinical trials have shown the vaccine can trigger an immune response in patients and reduce levels of disease.

The scientists behind the vaccine now hope to conduct larger trials in patients to prove it can be effective against a range of different cancers.

They believe it could be used to combat small tumours if they are detected early enough or to help prevent the return and spread of disease in patients who have undergone other forms of treatment such as surgery.

Cancer cells usually evade patient‘s immune systems because they are not recognised as being a threat. While the immune system usually attacks foreign cells such as bacteria, tumours are formed of the patient’s own cells that have malfunctioned.

Scientists have, however, found that a molecule called MUC1, which is found in high amounts on the surface of cancer cells, can be used to help the immune system detect tumours.

The new vaccine, developed by drug company Vaxil Biotheraputics along with researchers at Tel Aviv University, uses a small section of the molecule to prime the immune system so that it can identify and destroy cancer cells.

A statement from Vaxil Biotheraputics said: “ImMucin generated a robust and specific immune response in all patients which was observed after only 2-4 doses of the vaccine out of a maximum of 12 doses.

“In some of the patients, preliminary signs of clinical efficacy were observed.”

The results are still to be formally published but if further trials prove to be successful the vaccine could be available within six years.

As a therapeutic vaccine it is designed to be given to patients who are already suffering from cancer to help their bodies fight off the disease rather than to prevent disease in the first place.

Cancer cells contain high levels of MUC1 as it is thought to be involved helping tumours grow. Healthy human cells also contain MUC1, but have levels that are too low to trigger the immune system after vaccination.

When a vaccinated patient’s immune system encounters cancer cells, however, the far larger concentration of MUC1 causes it to attack and kill the tumour.

Cinnamon and Honey-medical properties.


Cinnamon and Honey

Honey is the only food on the planet that will not spoil or rot. It will do what some call turning to sugar. In reality honey is always honey. However, when left in a cool dark place for a long time it will do what I rather call “crystallizing” .

When this happens I loosen the lid, boil some water, and sit the honey container in the hot water, off the heat and let it liquefy. It is then as good as it ever was.

Never boil honey or put it in a microwave. To do so will kill the enzymes in the honey.

Facts on Honey and Cinnamon:

It is found that a mixture of honey and Cinnamon cures most diseases.. Honey is produced in most of the countries of the world. Scientists of today also accept honey as a ‘Ram Ban’ (very effective) medicine for all kinds of diseases.

Honey can be used without any side effects for any kind of diseases.

Today’s science says that even though honey is sweet, if taken in the right dosage as a medicine, it does not harm diabetic patients.

Weekly World News, a magazine in Canada , in its issue dated 17 January,1995 has given the following list of diseases that can be cured by honey and cinnamon as researched by western scientists:

HEART DISEASES:
Make a paste of honey and cinnamon powder, apply on bread, instead of jelly and jam, and eat it regularly for breakfast. It reduces the cholesterol in the arteries and saves the patient from heart attack. Also, those who have already had an attack, if they do this process daily, they are kept miles away from the next attack. Regular use of the above process relieves loss of breath and strengthens the heart beat. In America and Canada , various nursing homes have treated patients successfully and have found that as you age, the arteries and veins lose their flexibility and get clogged; honey and cinnamon revitalize the arteries and veins.

ARTHRITIS:
Arthritis patients may take daily, morning and night, one cup of hot water with two spoons of honey and one small teaspoon of cinnamon powder. If taken regularly even chronic arthritis can be cured. In a recent research conducted at the Copenhagen University , it was found that when the doctors treated their patients with a mixture of one tablespoon Honey and half teaspoon Cinnamon powder before breakfast, they found that within a week, out of the 200 people so treated, practically 73 patients were totally relieved of pain, and within a month, mostly all the patients who could not walk or move around because of arthritis started walking without pain.

BLADDER INFECTIONS:
Take two tablespoons of cinnamon powder and one teaspoon of honey in a glass of lukewarm water and drink it. It destroys the germs in the bladder.

CHOLESTEROL:
Two tablespoons of honey and three teaspoons of Cinnamon Powder mixed in 16 ounces of tea water, given to a cholesterol patient, was found to reduce the level of cholesterol in the blood by 10 percent within two hours. As mentioned for arthritic patients, if taken three times a day, any chronic cholesterol is cured. According to information received in the said Journal, pure honey taken with food daily relieves complaints of cholesterol.

COLDS:
Those suffering from common or severe colds should take one tablespoon lukewarm honey with 1/4 spoon cinnamon powder daily for three days. This process will cure most chronic cough, cold, and clear the sinuses.

UPSET STOMACH:
Honey taken with cinnamon powder cures stomach ache and also clears stomach ulcers from the root.

GAS:
According to the studies done in India and Japan, it is revealed that if Honey is taken with cinnamon powder the stomach is relieved of gas.

IMMUNE SYSTEM:
Daily use of honey and cinnamon powder strengthens the immune system and protects the body from bacteria and viral attacks. Scientists have found that honey has various vitamins and iron in large amounts. Constant use of Honey strengthens the white blood corpuscles to fight bacterial and viral diseases.

INDIGESTION:
Cinnamon powder sprinkled on two tablespoons of honey taken before food relieves acidity and digests the heaviest of meals.

INFLUENZA:
A scientist in Spain has proved that honey contains a natural ‘ Ingredient’ which kills the influenza germs and saves the patient from flu.

LONGEVITY:
Tea made with honey and cinnamon powder, when taken regularly, arrests the ravages of old age. Take four spoons of honey, one spoon of cinnamon powder, and three cups of water and boil to make like tea. Drink 1/4 cup, three to four times a day. It keeps the skin fresh and soft and arrests old age. Life spans also increase and even a 100 year old, starts performing the chores of a 20-year-old.

PIMPLES:
Three tablespoons of honey and one teaspoon of cinnamon powder paste. Apply this paste on the pimples before sleeping and wash it next morning with warm water. If done daily for two weeks, it removes pimples from the root.

SKIN INFECTIONS:
Applying honey and cinnamon powder in equal parts on the affected parts cures eczema, ringworm and all types of skin infections.

WEIGHT LOSS:
Daily in the morning one half hour before breakfast on an empty stomach, and at night before sleeping, drink honey and cinnamon powder boiled in one cup of water. If taken regularly, it reduces the weight of even the most obese person. Also, drinking this mixture regularly does not allow the fat to accumulate in the body even though the person may eat a high calorie diet.

CANCER:
Recent research in Japan and Australia has revealed that advanced cancer of the stomach and bones have been cured successfully. Patients suffering from these kinds of cancer should daily take one tablespoon of honey with one teaspoon of cinnamon powder for one month three times a day.

FATIGUE:
Recent studies have shown that the sugar content of honey is more helpful rather than being detrimental to the strength of the body. Senior citizens, who take honey and cinnamon powder in equal parts, are more alert and flexible. Dr. Milton, who has done research, says that a half tablespoon of honey taken in a glass of water and sprinkled with cinnamon powder, taken daily after brushing and in the afternoon at about 3:00 P.M. when the vitality of the body starts to decrease, increases the vitality of the body within a week.

BAD BREATH:
People of South America, first thing in the morning, gargle with one teaspoon of honey and cinnamon powder mixed in hot water, so their breath stays fresh throughout the day.

HEARING LOSS:
Daily morning and night honey and cinnamon powder, taken in equal parts restores hearing. remember when we were kids? We had toast with real butter and cinnamon sprinkled on it!
