Cancer Treatment Breakthrough: Scientists Have Found a Method to Make Leukemia Cells Kill Each Other

1 of 2

The cure for cancer hasn’t been discovered yet, but a recent scientific breakthrough gives hope for improved treatment for leukemia and possibly other cancers, too.

Cancer – The Ongoing Battle

Cancer is the timeless enemy.

According to the National Cancer Institute, about 1.6 million new cancer cases will be diagnosed in the U.S. in 2015 and about 589,000 people are likely to die from it.

In a normally functioning body, the cells keep dividing into new cells when the body requires. When old and damaged cells die, they are replaced by new cells.

In cancer, the cells begin multiplying relentlessly and spread out to surrounding tissues. Over time, the cells exhibit increasingly abnormal behavior – damaged and old cells no longer perish and new cells keep forming and dividing.

These extraneous cells may eventually become cancerous tumors.

However, not all cancers physically indicate their presence through tumors. Leukemia, or blood cancer, is one example.

The current treatments, including chemotherapy and radiation therapy among others, have proven to be highly effective.

However, they come with many side effects, some of which can be very serious. They do a solid job of inhibiting the growth of malignant cancer cells, but they also damage and kill the surrounding healthy cells.

While finding a cure for cancer would be the ultimate wish fulfilment, it still feels like a pipe dream.

However, there might just be a way of turning certain cancer cells into antibodies that could banish the remaining malignant cells to extinction.

According to a 2015 study conducted by scientists at The Scripps Research Institute (TSRI) and published in the Proceedings of the National Academy of Sciences, such a groundbreaking cancer therapy might be achievable, after all.

A Chance Discovery

As part of another study, the scientists were working to find therapies for certain cell and blood disorders. For this purpose, they exposed immature bone marrow cells to antibodies, hoping they would trigger the bone marrow cells to grow and mature into a specific variety of blood cells.

Their hopes were fulfilled — the antibodies had the desired effect.

However, what they discovered next would take their study in a completely new direction.

Much to their astonishment, certain antibodies had a completely new and wonderfully strange effect on the bone marrow cells.

They triggered the maturation of the bone marrow cells into completely new cell forms – the types of cell forms the scientists weren’t expecting at all.

This raised a critical question: Can this method be used to transform malignant leukemia cells into noncancerous cells?

A Way Forward

The TSRI scientists began a new study. They tested 20 of the newly discovered radical growth-activating antibodies on leukemia cells from human patients, and found one antibody in particular had an incredibly potent effect on cancer cells.

This particular antibody, when exposed to the leukemia cells, matured and converted them into vital support cells of the immune system called dendritic cells.

While this in itself was a discovery of mammoth proportions, that was not all they found. The scientists noted that the dendritic cells matured further with prolonged exposure to antibodies in other lab conditions.

As they matured, they turned into “killer cells” and bore a high resemblance to the natural killer (NK) cells innately produced by our immune system to fight cancers.

Possibilities for Leukemia Treatment

This discovery is especially vital to leukemia treatment, as compared to treatment of other types of cancers. This is simply because of the way leukemia works in the body.

It grows and persists due to the proliferation abilities of certain types of cells central to leukemia’s progression– the cancer stem cells.

These cells possess the remarkable ability of maintaining themselves while multiplying into thousands of more cancerous cells.

While the cells produced from this proliferation are not capable of producing further cells, they are still abundant and highly potent.

The problem with current treatments for leukemia like chemotherapy, radiation and bone marrow transplants is their inefficacy in identifying and destroying all cancer stem cells.

Also, these cells have such strong built-in defenses that they may survive these treatments. The cells that aren’t eradicated eventually multiply again, leading to a relapse of leukemia. This is the reason that the survival rate in leukemia patients rarely goes beyond 5 years.

This is why the discovery by TSRI scientists is so important. The antibody’s ability to differentiate cancer stem cells, combined with chemotherapy, radiation and transplants, could provide highly effective and focused treatment. This could significantly improve the survival rate, and may even translate into a cure.

  1. so far I remember Dr. Sheegar ‘S lab at CHLA was working on NK CELL , IL 4 and monocytes in the year of 2000 when I was Post Doc fellow at CHLA in another lab. it was very much exciting .
