Dendritic cells are the antigen presenting cells (APCs). They play a key role in regulating the adaptive immune response. T cells can recognize the antigen only when they are processed and presented in the context of MHC molecules (type I or II) by the professional antigen presenting cells (APCs). DCs are referred to as professional APCs, since their main function is to present antigens, and only DCs have the unique ability to induce primary immune response in the resting naïve T cells which have not experienced the antigen before. DCs capture antigens, process them and present them on the cell surface in a form that T cell can recognize along with appropriate costimulatory molecules essential for effective activation. Other types of APCs include

Glioblastoma (pronounced like gleO blastoma) is an incurable brain cancer,Survival rate is usually measured in months.This became a word that was instantly defined, researched, dissected, feared, and tried to comprehend and understand by family,friends and acquaintances of Larry McKee (McKee)who was personally affected from this single word, it was quickly added to their vocabulary, because of the of the events that transpired on October 22, 2011 that forever changed lives “Glioblastomas are tumors that arise from the astrocytes- the star-shaped cells that make up the “glue-like,” or supportive tissue of the brain. These tumors are usually highly malignant (cancerous) because the cells reproduce quickly and they are supported by a large network of blood vessels.”(A.B.T A..) He was diagnosed with stage four.

Glioblastoma is the most common and aggressive form of malignant brain cancer in adults. On average, 8 of every 100,000 people in the U.S. are diagnosed with glioblastoma every year – representing approximately 2% of all cancers diagnosed [1]. Glioblastoma tumors form when astrocytes, star-shaped cells which support and protect the brain, re-enter the cell cycle and start to rapidly divide. Because the brain is supported by a large network of blood vessels, tumors grow quickly and are difficult to remove surgically. Present treatments for glioblastoma are limited to surgery, radiation therapy, and chemotherapy; however, despite these interventions tumors are likely to regrow. Consequently, typical survival time following glioblastoma diagnosis is less than 2 years.

level? A mutation in just one allele of proto-oncogenes can cause over production of cells tumor, and thus tumor formation, because they are dominant. Tumor suppressor genes require mutations of both alleles to inhibit function because they are recessive.

There were three trial phases that had to be completed. The first phase was to inject the Onyx-015 at the tumor site with a low dosage to see how the body responds and to observe the side effects. The results stated that patients had flulike symptoms including fevers, nausea and other effects. The main conclusion from the first phase trial was that the Onyx-015 virus did not have a big affect on the injected tumor. Only 5 of the 22 patients had a response to the tumor with the low dosage of the virus [13].

Glioblastoma(GB) is the most common primary malignant solid brain tumor in adults1. Known for its aggressive characteristics and poor prognosis, the median survival rates of GB patients remain less than 18 months2,3. Tumor relapse owing to chemotherapeutic resistance is almost universal and GB is no exception, thus reflecting in high mortality and morbidity rates4. The WHO 2016 classification of brain tumors identifies GB tumors based on histology, molecular and genetic characterization into defined transcription profiles such as classical, neural, pro-neural and mesenchymal types5. Additionally, the commonly occurring genetic aberrations of primary GB are amplifications/mutations of EGFR, PDGFRA, PTEN, and of secondary GB are IDH1, MDM2

Dendritic cells use chemokines to find their way to the lymph node. T-cells originate in the bone marrow from hemopoetic stem cells along with B-cells. When T-cells receive the notch signal, they migrate to the thymus where they mature. T-cells go through V(D)J recombination then preTCR go through VJ recombination. Eventually they make it to positive selection which selects for MHC restricted cells and then negative selection where self-reacting cells are eliminated. Net is when the T-cells either become helper cells or cytotoxic

Grade four glioblastoma multiforme (GBM) is a type of malignant brain tumor. It is caused by a chromosome defect and specific gene mutation that leads to uncontrolled growth of certain brain cells. (Foundation, 2017) GBM begins in the brain and is the most aggressive type of cancer. The cancer usually reoccurs even with maximum treatment. Grade four glioblastoma multiforme survival rate following the diagnosis is in a 12-15 month range. Most people don’t survive longer than five years after diagnosis; even with treatment. Without treatment, survival is typically 3 months. (Foundation, 2017) Symptoms of GBM are severe. Symptoms of the disease hemiparesis, nausea, vomiting, headache, memory loss, and seizures. The most dominant symptoms are progressive memory, personality, or neurological deficit, due to temporal and frontal lobe involvement. With GBM the symptoms will vary depending on the location of the tumor, and its pathological properties. (Foundation, 2017)

According to the WHO the glioma divides in to four grades depends on the biologoical behavior and degree of malignancy.

The most aggressive and dangerous form of brain cancer is Glioblastomas (GBM). As the tumors grow, they put pressure on the brain which can cause changes in healthy brain function and pain. Glioblastomas represent 15% of brain tumors. Few patients live past three years after a diagnosis of GBM. Even with the maximum treatment of surgery, chemotherapy, and radiation, the cancer usually recurs. The most common length

Glioblastoma is a very rare cancerous brain tumor that grows very rapidly and is normally fatal (Glioblastoma, ABTA). Up to this point in time the treatment options for this type of cancer are surgery, radiation, and chemotherapy which aren't always very effective. Matthias Gromeier, MD at Duke University, made groundbreaking research that discovered that physicians could engineer the polio virus (PVS-RIP) in a way they could use to kill the glioblastoma cells (Targeting Cancer with Genetically Engineered Poliovirus, Duke). The PVS-RIP or genetically engineered poliovirus is administered to the patient by directly injecting the virus into the tumor and then the virus attacks and kills the glioblastoma cells (Targeting Cancer with Genetically Engineered Poliovirus, Duke). This treatment is the best so far because: it is far less aggressive than the very violent process of removal when using surgery as a treatment method, The PVS-RIP does not have the very harmful side effects of radiation therapy, and is a lot more effective than chemotherapy(Glioblastoma Cure Remains Elusive Despite Treatment Advances, Bryan

For this journal entry, I am to answer the question, “How would you decide whether to e one of the first individuals to try a ‘new’ vaccine?” Even prior to reading and evaluating the assigned article by the Institute for the Future, I had previously decided that should vaccine come along with the ability to halt melanoma, I would most likely be in favor of allowing the injection of a trial dose. My reasons for doing so are in hoping that my trial of a vaccine would help others, especially my family members, as there is a history of melanoma in my family. However, after reading the article, I am even more encouraged to allow a trial vaccine. In the article, Avery (2011) discusses the reprogramming of T-cells to recognize cancer cells as invaders, and fight them (para. 4).To me, this is no different than my taking synthetic thyroid hormones every day for the rest of my life, to stay alive.

Gliomas are broad category of brain tumors arising from glial cells. They are the most common primary malignant neoplasms of the central nervous system. They are classified into low-grade (WHO grades I and II) and high-grade (WHO grade III and IV) tumors. Almost 80% of gliomas are astrocytic tumors including Glioblastoma multiforme (GBM). Diagnosis of glioma includes a CT scan/MRI scan and biopsy. These tumors are highly resistant to current treatment modalities including surgery, radiation therapy, chemotherapy, corticosteroids, antiangiogenic therapy, and experimental approaches such as gene transfer, their prognosis is dismal.Malignant gliomas results from a multistep process which involves genetic alterations arised from innate and environmental

Simply put, the route of immunization is the path used to introduce the immunization to a person’s body. There are several standard methods of immunization and administering a vaccine via the correct route is a critical factor to the success of the immunization. Typically, vaccines are given intramuscularly, subcutaneously, by intradermal injection (the topmost layer of skin), orally, or intranasal via nasal spray. Vaccines

In 2007, it is predicted that almost 1.5 million people will be diagnosed with cancer in the United States (Pickle et al., 2007). More than half of these cancer patients will undergo the use of radiation as a means for treating cancer at some point during the course of their disease (Perez and Brady, 1998). Cancer, a disease caused by an uncontrollable growth of abnormal cells, affects millions of people around the world. Radiotherapy is one of the well known various methods used to treat cancer, where high powered rays are aimed directly at the tumor from the outside of the body as external radiation or an instrument is surgically placed inside the body producing a result of internal radiation. Radiation is delivered to the cancerous regions of the body to damage and destroy the cells in that area, terminating the rapid growth and division of the cells. Radiation therapy has been used by medicine as a treatment for cancer from the beginning of the twentieth century, with its earliest beginnings coming from the discovery of x-rays in 1895 by Wilhelm Röntgen. With the advancements in physics and computer programming, radiation had greatly evolved towards the end of the twentieth century and made the radiation treatment more effective. Radiation therapy is a curative treatment approach for cancer because it is successful in killing cancerous tumor cells and stop them from regenerating.
