Immune system

what does that entail? The disease derives from a virus labeled the Human Immunodeficiency Virus (HIV). Once infected with HIV it causes the body to try and fight the infection yet in doing so only cripples the body's immune system. In time the virus slowly tears down the immune system which makes it much hard to defend itself from the germs it used to be able to protect the body from. Leading to AIDS which is the vulnerability to sickness thus resulting in death. According to Ebscohost the…

the inner mucus layer cannot be penetrated. However, because of the huge diversity and quantity of gut microbiota there is moments when the inner mucous is breached. The bacteria that have migrated into the inner mucus layer is recognized by innate immune cells termed dendritic cells. Dendritic cells contain pattern recognition receptors (PRRs) such as Toll-like receptors (TLRs) that recognize microbial associated molecular patterns (MAMPs). Both pathogen and commensal microbiota contain MAMPs…

Monkeys are the perfect choice for this study, given that they have the closest immune systems to those of the human model. As such the monkeys will be given the Ebola vaccine and then a titer test will be performed and the results checked to see if the vaccine is actually working as planned or must be altered. The titer should show the…

INTRODUCTION Systemic Lupus Erythematosus (SLE) is an auto-immune system. Auto mean self. Autoimmune means that our immune system cannot differentiate between foreign invaders and our own healthy body tissues and decide that our healthy cells are foreign substance. Thus, creating autoantibodies which are protein that attack and eventually destroy the healthy tissues. This means that our body ability to prevent and fight against infection are reducing. SLE is more than any connective tissues…

intestines. Alcoholism can cause many problems to the liver such as inflammation, steatosis, alcoholic hepatitis, fibrosis, and cirrhosis. Steatosis is when the liver is infiltrated with fat because of the change in metabolism caused by the alcohol in the system. Alcoholic hepatitis is when the liver is inflamed because of excessive amounts of the alcohol over a short period of time. Fibrosis is the formation of large amount of scar tissue. Cirrhosis is liver damage that can lead to scarring and…

1954. Such medical achievement led the world into a new era where organs can be used for people other than the host; not only did the accomplishment open up the possibilities for saving more lives, it also unlocked the secrets of human bodies’ immune system. Although the first organ transplantation successfully performed in the U.S. might have received different reactions among people and provoked discussions about its ethics, the result of this medical procedure was an incredible medical…

Chickenpox is an illness caused by the Varicella zoster virus. Chickenpox is now less common owing to widespread vaccination, but it was once and almost universal childhood experience. First symptom of chickenpox in early childhood is usually an itchy rash that appear on the head and spread throughout your body. The rash becomes raised, and blister is form. Blister can be formed on mucous membrane such as inside the mouth, nose, throat, and vagina. The blisters crust over and will disappear…

Rumors regarding vaccine safety have been ringing around the world since 1998. Andrew Wakefield, a discredited publisher who is infamous for releasing a poorly evidenced article that suggested autism and bowel issues were caused by vaccines is responsible. Ever since this source of information was released to the public, there has been worldwide skepticism related to vaccine safety. Despite the fact that several credible sources have disproved the anti-vaccination campaign, it’s still the source…

for themselves and their children. Understanding the way the immune system works to cause immunity to certain diseases is crucial in understanding how and why vaccinations work. Active, natural immunity occurs when a foreign invader, such as a specific organism that can cause the flu, chicken pox, measles, and other diseases enter the human body causing the immune system to begin producing antibodies to destroy it. This is known as an immune response.…

NOD2 gene variants) has shown to have a role in contributing the development of IBD which is thought to have a link in the dysregulation of the body immune system that may affect the normal flora.1,6,7 This theory is believed that certain environmental and behavioural factors can trigger this dysregulation of the immune system and consequently leading to a chronic inflammation of the gut.6,7 However, it is important to note that genetics alone is not solely responsible in the aetiology…
