Is Cell Treatment Effective?
Stem cells can be used to treat a variety of diseases and injuries. They also help to
repair the body and restore its normal functions. The cells can be collected from
various sources including bone marrow avpress.marketminute, adipose tissue, umbilical cord, and oral
mucosa.
The stem cells are extracted from these tissues and then they are injected into the
patient’s body, usually through an IV infusion. The process can take a while and the
results depend on the individual’s condition and health.
Some cell therapies http://avpress.marketminute.com/, such as CAR T-cell therapy, can cure blood cancers and other
kinds of lymphoma that don’t respond to chemotherapy or other treatment. They
also may be helpful for people whose blood cancers have come back after they’ve
received initial treatments such as chemotherapy.
But they do have potentially life-threatening side effects. These can include cytokine
release syndrome (CRS), which is an overactive immune response, and
neurotoxicity, which can be caused by inflammation in the brain.
Another type of cell treatment is called adoptive cell immunotherapy, and it uses a
person’s own immune cells to attack cancer. It uses engineered T-cell receptors to
detect and destroy cancer cells that contain proteins called antigens. It is
particularly effective in some kinds of melanoma and sarcoma, but it has been used
to treat other types of cancers.
Researchers are working on a variety of different cell therapies that have been
shown to be safe and effective in small clinical trials. Some of them are in
development as treatments for cancer, while others are in development to help
people recover from other conditions such as heart disease and diabetes.
One type of cellular therapy is a type of engineered T-cell receptor called CAR T-
cells, which use portions of synthetic antibodies that can recognize a specific
tumor’s antigens on the surface of the cells. The CAR T-cells are genetically modified
and infused into the patient’s bloodstream, where they initiate a range of immune
responses to target the cancer cells that they’re targeting.
Other types of cellular therapy are based on the ability of immune cells to invade
and infiltrate the tumor. They include tumor-infiltrating lymphocytes, which are
immune cells that have entered the tumor and stayed there. They’ve been used in
several cancers, including melanoma and cervical cancer, and researchers at NCI are
studying them for use in many other types of cancer.
These types of cell therapies have shown promise in treating some people with
certain cancers, including melanoma, sarcoma and rhabdomyosarcoma, but more
research is needed to build safer, longer-lasting versions that can be given directly
to patients.
The researchers have also developed ways to make CAR T cells that can stay in the
blood for a longer period of time, allowing them to stick around and continue
attacking the cancer cells in the patient’s body. This may lead to a lessening of the
risk of the immune system rejecting the CAR T-cells or causing them to relapse.
Other types of cellular therapies, such as autologous stem cell transplants and
adoptive cell immunotherapy, are also being tested in the clinic. These methods are
currently being evaluated in large clinical trials for cancers and other conditions,
with promising results. However, these treatments are not yet approved by the FDA
for use in the U.S. They are not covered by insurance, and they can cost thousands
of dollars to receive.
