The June 10, issue this month of the journal Blood, prints study that reveals new technique victorious in dramatically shrinking B cell lymphoma.
Scientists from Scripps Research Institute have detected a new way to target and destroy certain cancerous cells. This evidence could possibly point to new therapies to treat Lymphoma and other related cancers.
Professor James Paulson, lead researcher of the study, stated that there is high interest in progressing this technology to see if it can be used in humans and to ascertain other forms of this kind of targeting.
Professor Paulson has examined glycoprteins for numerous years among his research studies. He has initiated new ways of study and manipulations of these molecules.
In this research professor Paulson and his associates adapted some of the labs awareness to a problem with major medical importance, to find a novel approach to aim and destroy cancer cells.
Especially, in this new study, researchers deployed to invaded B cell lymphoma which include Hodgkin lymphoma and non Hodgkin lymphoma, a form of cancer that is most prominent in older persons and those that have weak immune systems. Every year there are 70,000 persons diagnosed with B cell lymphoma in the United States. The medication rituximab is frequently capable treatment for the disease, however, each year there are still 22,000 deaths from B cell malignancies.
Usually, B cells administer a vital immune function spreading throughout the blood stream to aide in the assault of infectious agents. However, when B cells become cancerous, the issue is how to distinguish which ones they are out of a multitude of other molecules in the body and aim at them for destruction while not harming surrounding tissues.
Due to the fact of professor Paulsons past research he was knowledgeable in the fact of B cells owning a particular receptor protein on the surface that acknowledges particular sugars located on glycoproteins. The researchers needed to develop a useful potential therapeutic which carries the same sugars to identify and be able to aim at these cells.
Researchers mixed to distinct types of molecules forming one, using both new and old technology. One part of the possible therapeutic was made up of a certain sugar called ligand acknowledged by the B cell receptor referred to as CD22, designated on the surface of B cells. Attaching it to the surface of the other part of the possible therapeutic was a non particle refereed to as liposome, packed with a strong of a substantiated chemotherapy drug.
They already had knowledge in how the liposomes react in the body since they are already approved medications. They are designed so they do not use up macrophages in the liver. They applied the same formula, attached legands and proceeded to vivo studies.
The chemotherapy medication placed in use was doxorubicin, used to treat vast types of cancers. Using a nanoparticle formulation of doxorubicin called Doxil. The drug is enclosed inside the liposomal nanoparticle, this protects normal cells from the medication until it comes upon the cancer.
Usually Doxil is quietly brought to the tumors by leaving leaky tumor vasculature, the medication slowly leaks out and destroys the tumor. When enhancing the nanoparticles with CD22 ligand it carries the drug inside the cell.
The findings were astonishing. Not one mouse in the control group survived to the end of the 110 day trail, however 5 of the eight mice who got a higher dose of the compound did survive.
Researchers then went to survey for any possible detections of residual tumor cells in the survivors. A mouse that is paralyzed with the disease has 95% of the cells in its bone marrow are tumor cells.
When they examined the bone marrow of those that lived up to 100 days, no tumor cells were located.
To broaden the results researchers checked the compound’s activity in blood sample of human patients with three types of B cell lymphomas, hairy cell leukemia, marginal zone lymphoma and chronic lymphocyte leukemia. Discovered was the compound also completely bond to and erased the diseased B cells.
Researchers excited by these results are now working to progress improving the drug platform along with looking into ways to heighten particular B cell targeting along with examining technology benefits of other chemotherapy agents.
A grant from the National Institute of Allergy and Infectious Diseases along with the National of General Medical Sciences of the National Institutes of Health funded this research.
The usual medical treatments of lymphoma, leukemia and Hodgkin and non Hodgkin lymphoma normally uses chemotherapy, radiation or both therapies. Even though these treatments do significantly improve patient survival, the side effects can be greatly horrendous.
Many alternative therapies are beneficial for patients with blood cancers for relief of many side effects. Alternative therapies do not consist of a breakdown for types of cancers. They run under cancer treatments. Here are some alternative therapies that can help the ill effects of chemotherapy and radiation therapy.
Has been proven in clinical studies to help with pain reduction and does decrease the patients use of narcotics for pain. It also has been very useful for vomiting, nausea and even constipation.
Clinic studies have shown that chiropractic treatments are beneficial to cancer patients. Some therapies applied maybe:
Spinal manipulations has a array of 35 or more techniques used. Can relieve extreme joint pain.
Exercise most often will be recommended to maintain flexibility and muscle tone.
Physio-therapeutic modalities which includes cold, heat, ultrasound and electric muscle stimulation.
The therapies used may consist of some of the following:
Nutritional therapy has two types which are split as specialized combination of nutrients aimed at cancer therapy. The other is more general which aides in boosting and strengthening health.
Enzyme therapy is in two types food and Proteolitic enzymes.
Herbal Extracts and Plant Products
Some of the herbal extract formulas and plants than maybe used are Essica, which is a tea consisting of Indian Rhubarb, Slippery Elm and others. Hoxsey made up of Poke root, burdock root, barberry root, buck thorn buck, stillinga root. One is oral consumption the other version is a salve if the cancer is close to the surface of skin.
