The host immune response is important in maintaining the health of periodontal tissues. The presence of pathogens in periodontal pockets will activate innate and adaptive immune responses in an attempt to clear the pathogenic threat as well as promote tissue homeostasis. However, the persistent presence of pathogens can cause the continuous activation of innate and adaptive immune responses; which in turn causes inappropriate inflammatory mediator (cytokine, chemokine, antimicrobial proteins…

There has been a great debate on vaccination. For individuals against the vaccination, there is dependency on herd immunity, which is the belief that having a large percentage of the population vaccinated, that the spread of certain diseases can be stopped, thus protecting the unvaccinated individuals (Hockenberry & Wilson, 2015, p. 196). The vaccination for measles, mumps and rubella (MMR) are given together in a single dose at ages 12-15 months and then again at 4-6 years. While vaccination…

This project looked at how carbohydrates can have an effect on the ability of proteins to cross the blood-brain barrier (BBB). The blood brain barrier are formed by endothelial cells of the brain capillaries, restricts access to brain cells of blood-borne compounds and facilitates nutrients essential for normal metabolism to reach brain cells. This is a very tight regulation that results in the inability of small and large therapeutic compounds to cross the BBB. Lipidic systems can be…

In the end Vaccines do work! Medical technology has advanced further in the last 100 years than it has throughout history. We live our lives relatively disease free and we owe so much of that to vaccines. Despite the overwhelming evidence, people still have questions and concerns. Which is okay. In 1798, smallpox was killing hundreds of thousands of people every year. Until Edward Jenner that milkmaids who had gotten cowpox, a less deadly form of the disease, didn’t get smallpox. This was the…

Research on Allergies By Jonas Wilson, Ing. Med. Allergies are exaggerated immune responses to substances that would otherwise be seen as harmless. Allergies rank high on the list among the world’s most common health conditions. They begin when an allergen, the substance responsible for the reaction, causes the production of immunoglobulin E (IgE) antibodies, which coat mast cells. On subsequent re-exposure to the allergen, IgE reacts and causes the release of histamine and other…

What are chicken pox? Chicken pox is a viral disease that causes a fever and blistering in one area and spreads all throughout the body and ranges in two hundred fifty to five hundred blisters. The blisters tend to create a red rash and itchy feeling in the skin. Chicken pox, or varicella-zoster virus is most dangerous for babies because of the undeveloped immune system, and also for adults due to their weakening immunity through aging. No one really knows an exact time of when the virus was…

1. The immune system is a group of organs including your cells, proteins, and structure of the lymphatic and circulatory system that work together to keep the human body healthy. The immune’s system primary function is to protect all other organs systems from attack such as things like bacteria or prevent you from getting sick. Our body’s immune system includes three major parts. The first main defense of the immune system is known as barriers which is the first line of defense. Barriers…

1. A graft reject is a process in which the body immune system reacts or defends against the transplanted tissue. Because of this possibly, tissue typing or histocompatibility is used to minimize the chance of rejection of the recipient transplanted organ. The immune system attempts to defend the body against harmful substances such as germs, poisons, and sometimes, cancer cells. The major histocompatibility complex (MHC) gives the immune system the ability to distinguish between “self “and…

I chose lupus for my autoimmune disease. “Lupus is a chronic inflammatory disease that occurs when your body’s immune system attacks your own tissues and organs.” (Mayo Clinic, 2015). Lupus can cause inflammation that can affect the joints, skin, kidneys, blood calls, brain heart and lungs. Symptoms for lupus are fatigue, fever, joint pain, butterfly-shaped rash on face, and shortness of breath and chest pain. People who have lupus may have symptoms for some time that will disappear and may…

The job of the human body’s immune system is to fight against infection by detecting and destroying foreign bacteria and viruses, usually to much success. However, the immune system isn’t perfect, and can make mistakes. Sometimes, the immune system confuses a friendly part of the body for a pathogen, and begins attacking its own cells (Petrov, 2011). When these events occur, the body has contracted what is known as an autoimmune disorder. Autoimmune disorders have been rapidly growing problems…
