How to cure cancer cells?
The immune cell redirection approach has led to significant advances in cancer immunotherapy. More than 80 bispecific antibodies based on this approach are currently in development, most using CD3-based T-cell redirection. This promising technique is widely studied as it can be applied to a wide variety of cancer types.
What is the best alternative treatment for cancer?
This could be due to several factors, not the least of which include:
- dissatisfaction with chemotherapy side effects
- cost of chemotherapy, radiation, and surgery (especially with quality, affordable insurance options diminishing)
- growing interest in natural, holistic living
- increased concern with Big Pharma (you don’t have to be a conspiracy theorist to be concerned here)
How effective is stem cell treatment for cancer?
Transplants can be:
- autologous, which means the stem cells come from you, the patient
- allogeneic, which means the stem cells come from someone else. The donor may be a blood relative but can also be someone who is not related.
- syngeneic, which means the stem cells come from your identical twin, if you have one
Can a new gene therapy cure cancer?
Gene therapy replaces a faulty gene or adds a new gene in an attempt to cure disease or improve your body's ability to fight disease. Gene therapy holds promise for treating a wide range of diseases, such as cancer, cystic fibrosis, heart disease, diabetes, hemophilia and AIDS. Researchers are still studying how and when to use gene therapy.

What are the treatments for cancer?
For years, the foundations of cancer treatment were surgery, chemotherapy, and radiation therapy. Over the last two decades, targeted therapies like imatinib (Gleevec®) and trastuzumab (Herceptin®) —drugs that target cancer cells by homing in on specific molecular changes seen primarily in those cells—have also cemented themselves as standard treatments for many cancers.
How many T cells are expanded in the lab?
Once the collected T cells have been engineered to express the antigen-specific CAR, they are "expanded" in the laboratory into the hundreds of millions.
How to improve antigen durability?
One potential way to improve durability and perhaps at least forestall antigen loss, if not prevent it altogether, is to attack multiple antigens simultaneously . Several research groups, for example, are testing T cells that target both CD19 and CD22 in early-phase clinical trials.

What is the act of immunotherapy?
A rapidly emerging immunotherapy approach is called adoptive cell transfer (ACT): collecting and using patients' own immune cells to treat their cancer. There are several types of ACT (see the box below, titled "ACT: TILs, TCRs, and CARs"), but, thus far, the one that has advanced the furthest in clinical development is called CAR T-cell therapy.
What is the fifth pillar of cancer treatment?
But over the past several years, immunotherapy —therapies that enlist and strengthen the power of a patient's immune system to attack tumors—has emerged as what many in the cancer community now call the "fifth pillar" of cancer treatment.
How are T cells changed?
In CAR T-cell therapies, T cells are taken from the patient's blood and are changed in the lab by adding a gene for a man-made receptor (called a chimeric antigen receptor or CAR ). This helps them better identify specific cancer cell antigens. The CAR T cells are then given back to the patient.

Lisocabtagene maraleucel, also known as liso-cel (Breyanzi) Idecabtagene vicleucel, also known as ide-cel (Abecma) Many other CAR T-cell therapies (and similar types of treatment) are now being studied in clinical trials, in the hope of treating other types of cancer as well.
What antigen is used in cancer?
For example, in certain kinds of leukemia or lymphoma, the cancer cells have an antigen called CD19. The CAR T-cell therapies to treat these cancers are made to attach to the CD19 antigen and will not work for a cancer that does not have the CD19 antigen.
What is the T cell?
Chimeric antigen receptor (CAR) T-cell therapy is a way to get immune cells called T cells (a type of white blood cell) to fight cancer by changing them in the lab so they can find and destroy cancer cells. CAR T-cell therapy is also sometimes talked about as a type of cell-based gene therapy , because it involves altering ...
How long does it take for calcium to go down during leukapheresis?
The patient will need to stay seated or lying down for 2 to 3 hours during the procedure. Sometimes blood calcium levels can drop during leukapheresis, which can cause numbness and tingling or muscle spasms. This can be easily treated by replacing the calcium, which may be given by mouth or through an IV .
Why is car T cell not strong?
This chemotherapy is usually not very strong because CAR T cells work best when there are some cancer cells to attack. Once the CAR T cells start binding with cancer cells, they start to increase in number and can help destroy even more cancer cells.
Why do you need chemotherapy before car T cells?
A few days before the CAR T-cell infusion, the patient might be given chemotherapy to help lower the number of other immune cells. This gives the CAR T cells a better chance to get activated to fight the cancer.
How does immunotherapy work?
Immunotherapy is a promising strategy to treat cancer by stimulating the body’s own immune system to destroy tumor cells, but it only works for a handful of cancers. MIT researchers have now discovered a new way to jump-start the immune system to attack tumors, which they hope could allow immunotherapy to be used against more types of cancer.

Several clinical trials combining chemotherapy and immunotherapy drugs are underway, but little is known so far about the best way to combine these two types of treatment.
Can the immune system be reengaged to destroy tumors in mice?
By combining chemotherapy, tumor injury, and immunotherapy, researchers show that the immune system can be re-engaged to destroy tumors in mice.
Does Yaffe test for immunotherapy?
Yaffe hopes to test this approach in patients whose tumors have not responded to immunotherapy, but more study is needed first to determine which drugs, and at which doses, would be most beneficial for different types of tumors. The researchers are also further investigating the details of exactly how the injured tumor cells stimulate such a strong T cell response.
What is T cell treatment?
The new T-cell treatment is a type of immunotherapy, and it involves taking a patient's own immune cells - specifically, white blood cells called T-cells - and reprogramming them to attack tumours. It's sort of like creating a tailor-made vaccine response against cancer.
What is the function of T cells?
T-cells are white blood cells that are responsible for detecting foreign or abnormal cells - including cancerous ones - and then latching onto them to tell the rest of the immune system that they need to be attacked.
How does immunotherapy work?
This is where immunotherapy comes in - to put the system into overdrive, scientists perform what's known as adoptive T-cell transfer. This means they first extract patients' T-cells from their blood, and, using gene transfer, introduce receptors that will aggressively target a specific cancer cell. Once back inside the body, these newly engineered T-cells regenerate to create an army of immune cells prepped to take down tumours.
How many people died from cytokine release syndrome?
This is mainly because the potential side effects are severe - during the trials, 20 patients suffered symptoms of fever, hypotension, and neurotoxicity due to something called cytokine release syndrome, and two patients died. "Much like chemotherapy and radiotherapy, it’s not going to be a save-all," said Riddell .

For patients with other types of blood cancer, response rates have been above 80 percent, and more than half have experienced complete remission, cancer researchers reported at the American Association for the Advancement for Science conference over the weekend.
Can humans get immunotherapy?
Scientists have been working on immunotherapy for decades, but have only recently started testing this new T-cell therapy in humans. Due to the experimental nature of the research, for now, the trials have been limited to patients who are no longer responding to other treatments, and only have a few months to live.
Is Riddell's lab working on T-cell therapy?
Riddell's lab is now working on applying the T-cell therapy to a wider range of cancers - not just blood cancers - and is trying to make engineered T-cells safer and easier to design. The team also wants to track how long patients remain in remission following the treatment before progressing with broader trials.
