This can trigger cytotoxic T cells to kill cancer cells with the same antigen – often HPV viral proteins in cervical cancer. T cells may not be activated to their full potential – recall that the inhibitory receptor CTLA-4 on T cells sends a stronger signal than CD28, the activating receptor. Ipilimumab is added to treatment for this reason. It will work in conjunction with the released antigens, activating the T cells that can respond to the antigens and create an immune response against the cancer cells (LACC article). Adding ipilimumab to the chemo/radiation treatment would enhance the immune system’s ability to respond to the antigen released by the treatment.
The Monoclonal Antibody are directed to attach to a specific part of the cancer, marking the cancer cell as harmful and making it easy for the immune system to identify it and destroy it. Scientists are looking to to find out the reason lymphocytes turn into cancer, why they grow fast or live longer then they should. Once this is understood the focus will be on finding a cure for the disease. There are new drugs being tested on patients and studies are being done on how to improve steam cell transplant, and new drugs are being tested. A cure may be out of reach for time being but treatments and research are advancing every
Of those treatments the most important one is the use of drugs and is called chemotherapy. • This treatment includes wide group of drugs that have cytotoxic effects mainly on the rapidly dividing cells but not exclusively. So that’s why, it also have unwanted side effects on the life of normal cells in the body of a cancer patient. • The excessively active growth signaling pathways in cancer cells make them susceptible to huge variety of chemotherapeutic drugs whose target is growth signaling molecules and processes involved in cellular expression and replication. • But sometimes, in most of the patients whose cancer cell line was responding to chemotherapy, show a decrease or complete loss of response which results in tumor regrowth leading to cancer drug resistance.
There is also a vaccine therapy, which helps stimulate the patients immune system to help fight off lymphatic cancer. These treatments are still experimental and very expensive. In patients who have reoccurring lymphoma, higher doses of chemotherapy or radiation may be necessary in an attempt to kill the cancerous cells. These treatments also destroy the blood producing cells in the patient’s bone marrow. This sometimes requires a bone marrow transplant.
But the research has predominantly shown that the results of the expression of alpha5beta1 integrins yield beneficial results in terms of cancer tumor reduction. More research needs to be done, but the knowledge obtained from this experiment that alpha5beta1 integrin prevents premature cell death is an excellent step forward in the fight against cancer. There are untold possibilities of the medical applications of not only alpha5beta1 integrins, but all of the many integrins and cell adhesion molecules that play important roles in cell function.
Cancer Treatment With Gene Therapy Gene therapy has been progressing over the past half-century and has led to many discoveries pertaining to the treatment of cancer. Normal body cells can either become cancerous by losing or gaining a function. To treat cancer, scientists can either replace damaged genes (such as a damaged tumor suppressing gene) in the malignant cells or stop the cells from overexpressing genes (such as oncogenes, or genes that have been altered and can cause the development of cancer in normal body tissue) (Culver, 97). Gene therapy has many benefits over other cancer treatment methods. “ Gene therapy is the insertion of a functioning gene into the cells of a patient to correct an inborn error of metabolism (i.e.
It is important to note that the term cancer refers to a broad class of diseases as cancers have many different origins and must be treated differently. Can the immune system be trained to effectively treat or prevent certain cancers? First a look to the past to see where this theory came from to where it is taking us today, a look to the future where vaccines and potential cures could be the medical breakthrough of the century. For years the go to cancer treatment has been very invasive and often created hardships for patients. Today we are on the fast track of a breakthrough that could redefine typical cancer treatments, one that could and will save thousands who are at risk.
Several researchers have came to the conclusion that the best way to cure cancer would be to incorporate the practices together thus enhancing and bringing the positives from the two.Cancer is an important health problem that has drastically increased over the past couple of decades. It is now ranked as the second most common cause of death in the United States. Extensive research and analysis is very critical to determine the best method for treatment. Several Medical Doctors and Naturopathic Physicians have dived deeper and performed experiments using either drugs or CAM treatment and analyzed the results. Experts in the field of oncology have reviewed both CAM and pharmaceutical drug methods to determine which pathway is the best alternative for their patient’s health and well-being.
In 2013, the United States was said to have an estimated 1.6 million cancer patients. The majority of cancer patients turn to chemotherapy in hope to kill off all the spreading cancer cells so they can have a chance to live again. Chemotherapy is defined as the use of any drug to treat any disease, however people most commonly associate chemotherapy with drugs used to treat cancer. Although chemotherapy could be very effective, the rate of success solely depends on the type of cancer the patient has and could potentially be only one or two percent successful. Cancer is a method by which normal cells of the body mutate and develop quickly into abnormal cells.
One of the recent developments in the research behind oncogenesis and its relationship to cancer is the theory of “oncogenic addiction”. This theory explains the phenomena of “a tumor cell seemingly exhibiting dependence on a single oncogenic pathway or protein for its sustained proliferation and/or survival” (Sharma & Settleman 2007). These findings suggest that there may be a way to “switch off the crucial pathway of dependence”, which in theory should negatively affect or inhibit the cancer, “while sparing normal cells that are not similarly addicted” (Sharma & Settleman 2007). This has been established with the ability to inactivate “counterparts of oncogenic proteins in normal tissues” and see that there is toleration without “obvious consequences” (Sharma & Settleman 2007). This is the concept of “addiction” in cancer, and the dependence on particular genes to activate prolifer... ... middle of paper ... ...need to be developed to begin this study, we can infer from past research the steps in which determination of these relationships could be done.
