Inside our body is an unceasing battle, warding off dangerous invaders. The immune system in our body protects us from dangerous bacteria and harmful viruses. But is there more to the immune system and can we the use immune system for treatment? Right now, immunotherapy, the use of the immune system to fight cancer cell, is growing worldwide. It is highly effective than other methods of cancer treatment such as chemotherapy and could save future generation from cancer. There are several different types of immunotherapy and each has its own benefits, such as the blockade of proteins, genetically modified white-blood cells and the education of the white blood cell all shows that immunotherapy wields unlimited potential and could end cancer once and for all.
To understand immunotherapy, it is vital to know the how to immune system works. Immunotherapy typically works with the adaptive immune system, a subcategory of the overall immune system which contains both the T-cells and the B-cells. On the surface of the T-cells contains a protein known as the antigen receptor or TCR (T-cell receptor) which are responsible for

What makes immunotherapy so powerful is how it utilizes the T-cells and how it attacks cancer cells. Once a patient has gone through treatment, the T-cells will recognize and target the cancer cells. After the treatment ends, the memory T-cells will remember cancer cells from the TCR and attack it. This is why immunotherapy is more efficient than any other treatment, because of its ability to continuously fight cancer cells even after treatment. It also has very few or no side effect because it only attacks cancer cells, unlike chemotherapy or radiotherapy where it harms nearby healthy cells. One of the most important benefits for immunotherapy is that it can be applied to nearly all cancer cells. There are three different types of method of using the immune system to target cancer
The B cells, T cells, Macrophage, and Antibodies are all a very large part of the immune system. There are two types of T cells, killer and helper T cells. Killer T cells find and destroy cells infected with bacteria, and helper T cells control the activity of other cells in the immune system. Then, B cells are considered the “clean up crew,” attacking any bacteria or viruses the T cell left behind. They also make antibodies, which are essential for trapping invading viruses and
Early detection of breast cancer has helped prevent many fatalities, but what if we had a vaccination for all types of cancer? There is great hope for a cancer vaccination in the works as we speak. The PEI (Paul-Ehrlich-Institut,) which is the FDA of Germany, has found a way to get an accelerated approval to get a cancer vaccine called DCVax possibly approved by the USFDA (United States Food and Drug Administration). Over the past two and half years, a company by the name of Northwest Biotherapeutics has made major progress in finding a vaccination for all types of cancer through recent clinical trials. The trials have shown tremendous results with increased life expectancy and substantial results in the shrinkage of tumors.
The job of the immune system is to keep “foreign” invaders out of the body, or if one gets in, to seek it out and kill it. These foreign invaders are called pathogens, which are tiny organisms that can cause an infection in the body. Pathogens can be bacteria, parasites, and fungi (http://www.niaid.nih.gov/topics/immuneSystem/pages/whatisimmunesystem.aspx).
The immune system is one of the major systems of the human body. It protects the body from diseases and infections that could cause harm to a person’s body. To protect the body it distinguishes between unhealthy and healthy cells (National Institute). The immune system distinguishes between these cells to determine if the body is being invaded by a disease, or if the body is fine and healthy. It will fight off foreign contaminants if they are invading the body to potentially harm it. The immune system works to suppress any unwanted cells, microbes, etc. Without a proper working immune system, the human population would constantly be sick.
The function of the immune system is it helps play a vital part of our everyday lives. It helps protect our bodies where ever we go. Our immune systems help defend our bodies against germs and microorganisms. The immune system is made up of various special cells, tissues, organs and proteins. This special system does an amazing job of keeping our bodies healthy and in good shape from different diseases and infections.
To understand how immunotherapy works it helps to know how your immune system works to fight against cancer. Cancer cells have substances on their surfaces called tumor antigens that raise an alarm in the immune system that says cancer is present. Antigen presenting cells ( APCs) roam the body seeking out and ingesting tumor antigens. The APCs then activate B cells and T cells. The B cells differentiate into plasma cells and secrete antibodies that bind to the tumor cell and mark them for elimination ( a humoral immune response). When T cells are activated they proliferate and undergo expansion, seek out, and destroy cells bearing the specific tumor antigens ( a cellular immune response). Sometimes your immune response does not destroy all of the cancer cells and this r...
All human bodies have an immune system, which is a complex network of cells and organs that protect the body from germs and other foreign substances. A mistake can make the body unable to tell the difference between foreign substances and the body’s own cells. When this happens, the body makes auto-antibodies that attack body cells by mistake. When a foreign substance invades your body (like a cold virus or bacteria on a thorn that pricks your skin) your immune system attacks it. It tries to identify, kill and get rid of the invaders that might harm you. But sometimes problems with your immune system cause it to mistake your body’s own healthy cells as invaders and then repeatedly attack them. This is called an autoimmune disease.
Our immune system protects our bodies from pathogens like bacteria and viruses very efficiently in most cases. One big question that has come up is why does the immune system not respond to cancerous cells in the same way? Why are cancer cells not eradicated like other dangerous foreign cells? This seems very strange, especially since the immune system has cells that are specific to destroying cancer cells and virus-infected cells, called natural killer cells. To begin to answer this question it is useful to examine cancer cells and their interactions with the immune system in more detail.
The immune system has the important job of protecting the body from foreign invaders. It is made up of a network of cells (including white blood cells), tissue and organs. The foreign invaders the immune system fight include viruses, bacteria, microbes and pathogens. In order to stop these foreign invaders, there is a process known as immune response that attacks in three different lines of defence. Without this immune response, the body would be constantly under invasion by pathogens trying to attack and induce illness.
Childhood vaccinations have received a lot of media in the past few years, and parents continue to question whether or not they should have their children vaccinated. This topic is a very important issue because it seems to be a trend in our society where parents are not vaccinating their children. This then leads their children becoming more susceptible to unnecessary diseases/viruses that can be prevented with vaccines. The focus of the following articles was on the association of the specific vaccines measles, mumps, and rubella (MMR), and vaccines containing thimerosal, which has been a speculated reason for the cause of autism. This contentious hypothesis has many parents failing to vaccinate their children; this is especially true of many friends and family members of mine. They believe that vaccines can cause autism, and I want to prove otherwise.
A type of white cell, which is called the killer cells, is able to identify tumour cells simply by its change in its surface membrane. Other cells, called the helper cells, assist the killers to multiply and they then connect themselves to the cancerous cells to destroy them. There are two types of defence - the innate and the adaptive. The innate includes barriers like the skin and antibacterial enzymes within tears. The adaptive is based on specialized white blood cells which are lymphocytes and they respond to invasions by micro-organisms.
When a cell in our body has become infected or has become cancerous it’s surface changes. This is how the immune system can tell good cells from bad ones (the markings on the surface.) Once a bad cell has been recognized our bodies sends cells to destroy the damaged cell and prevent the spread of whatever caused the damage in the first place. The next step our body takes is to have the affected cells start to produce interferons and other helpful substances. These help to fight off unwanted organisms, and also to warn other cells of the invaders and prepare them to resist them therefore preventing the spread of disease.
Preventing serious infections by making a person immune to the infection is called immunization. This process is usually performed by the administration of a vaccine to stimulate the person’s immune system to protect them against a subsequent infection or disease. According to the World Health Organization (2016), more than 5 million deaths were prevented annually between 2010 and 2015 due to vaccinations that were used around the world. Vaccines work with the natural ability of the human immune system to develop immunity to fight disease. When a foreign infectious pathogen such as bacteria or a virus enters the body, it multiplies and becomes an infection and in many cases, this infection leads to an illness. To understand how vaccines
The immune system is a fascinating structure it defends the body against foreign invaders like bacteria, viruses and parasites. There are two primary forms that make up the immune system they are, innate and adaptive systems. Both the innate and adaptive system plays a large role in the immune system. The innate is the primary system to defend against foreign materials and the adaptive is the secondary system that responds to specific issues.
One of the most common mysteries in the world is the development of autoimmune diseases. An autoimmune disease is when the immune system, which usually keeps your body healthy thinks that your healthy cells are antigens and attacks them. This is irony right? It is against properties of evolution for an immune system to attack itself causing sickness and possibly death if untreated. There are about 80 different types of autoimmune diseases, which usually have periods of little to no symptoms and worsening symptoms. What particularly creates confusion in the world is the autoimmune disease, inflammatory bowel disease, which affects almost about five million people worldwide.
