Disorder Of The Immune System

Disorder Of The Immune System – Evolution can be blamed for our autoimmune diseases like lupus, multiple sclerosis and rheumatoid arthritis. For the first time, we have evidence that people who are more susceptible to these diseases are because their immune systems are better equipped to fight against dangerous infections, allowing them to live longer.

“So many autoimmune diseases affect all types of tissues,” said Andrea Graham, a developmental biologist at Princeton University, at the annual meeting of the International Society for Development, Medicine and Public Health in Durham, North Carolina, last month. So what could explain the existence of these conditions? “One possible answer is that vulnerability to mediated disease is simply the price we have to pay for a strong and rapid defense against infection.”

Disorder Of The Immune System

Graham and his colleagues found evidence for that idea using a longitudinal study of elderly people in Taiwan. It tracked more than 1,000 people born between 1892 and 1953 over the past 27 years.

The team collected blood samples from 639 of these people between 2000 and 2006 and measured levels of “self-reactive” antibodies, which are capable of attacking the body’s own tissues. They found that people with higher levels of these antibodies were more likely to live longer.

For any given age, participants with high levels of autoreactive antibodies had an average 33% lower risk of dying that year. These people also seem less likely to have some type of chronic viral infection.

The downside is that these antibodies are the ones involved in autoimmune diseases. The kidney is one of the first organs affected by autoimmune lupus, so the team also looked at urine samples, which can indicate kidney health. They found that people with high levels of autoreactive antibodies may be more likely to develop lupus.

What Are Autoimmune Disorders?

Gabriel Sorcy, an evolutionary biologist at the University of Burgundy in France, says what is remarkable about this study is that it explains in evolutionary terms why human evolution could not eliminate autoimmune diseases.

The work was inspired by Graham’s findings from a similar study in the UK that involved sheep rather than humans. For the past 30 years, researchers have been documenting the health and lifestyles of more than 7,000 gray sheep on the Scottish island of St. Kilda.

Analyzing the antibodies in the blood samples of the sheep, Graham’s group found that there was a correlation between the levels of autoreactive antibodies and antibodies against parasites, and that there were high levels of autoreactive antibodies in sheep families. Together, the findings suggest that genetics influence the level of autoreactive antibodies, and that this is associated with building stronger defenses against parasites. This appears to provide an evolutionary advantage – sheep with higher levels of autoreactive antibodies live longer.

Studying Rare Immune Disorders Gives Insights On How The Immune System Deals With Infections

“Autoimmunity used to be thought of as a bad thing, a result of the immune system malfunctioning instead of attacking what it should,” says Aaron Blackwell, an evolutionary anthropologist at the University of California, Santa Barbara. “These studies suggest that there may be an autoimmune function,” says Blackwell.

Statistical analysis of sheep data showed that the correlation between survival and high levels of autoreactive antibodies could not be fully explained by better parasite control. This may mean that autoreactive antibodies aren’t just a side effect of a strong immune system—they can also do something useful. Other research suggests that autoantibodies may help clear dead cells and other debris from the body, and they may play a role in detecting cancer cells.

The emerging picture, Blackwell says, is that physiological responses are the product of long evolutionary processes and often serve a function that makes an animal more likely to survive under the right conditions. “I would expect these results to apply to many different species and human populations,” he says. Autoimmune diseases are diseases in which the immune system mistakenly attacks your own body. Normally, the immune system defends your body against pathogens, such as bad bacteria and viruses, and sends out hordes of fighting cells to attack these foreign and potentially harmful invaders when it senses them.

Nih Study Implicates Hyperactive Immune Syste

The immune system usually differentiates which are foreign cells and which are your own cells. However, in the case of an autoimmune disease, your immune system mistakes a part of your body – such as your joints, skin, nerves, thyroid gland, adrenal glands or blood cells – as foreign. Therefore, it sends autoantibodies (proteins) to attack its perfectly healthy cells.

Some autoimmune diseases affect only one organ (eg type 1 diabetes affects the pancreas), while other disorders (eg systemic lupus erythematosus (SLE)) attack the whole body (1).

Well, being diagnosed with any chronic disease is frustrating. You’ll have to learn to live with your new regimen—as well as familiarize yourself with new medical terms, medications, and lifestyle changes. Then also the way it affects your loved ones. Family dynamics are changing. You need to make time in your schedule for doctor’s appointments, meal planning, treatments and anything else that this new health condition may require. All of these are related to immune system disorders. But what exactly are they? What are the most common symptoms? And what can you do to cure them?

The immune system is one of the most complex systems in your body. It is made up of cells, organs and proteins known as antibodies that fight infections and viruses that enter your body. Whenever your immune system is actively protecting you from harm, your body temperature rises, resulting in a fever, which also triggers the body’s repair process. However, in some people, the immune system can become overactive. When this happens, it can mistakenly attack normal parts of your body – like cells and tissues. This is known as an autoimmune disease.

There are two ways that a person can weaken the immune system. Primary immunodeficiency means you were born with a disease that weakens your immune system. And, secondary immunodeficiency means that your immune system is weakened due to diseases that developed later in life, the use of certain medications and/or life events such as trauma or environmental factors.

When The Immune System Attacks The Brain

There are different types of autoimmune disorders. Therefore, it may require a long litany of tests to determine whether you have it or not. However, before it reaches this point, you will usually experience several symptoms. They can vary from mild to severe depending on the situation. Among the most popular are:

Depending on the disease, you may also experience bowel changes, abdominal cramps, diarrhea, unexpected weight loss, increased urination, and excessive thirst. It is also possible for symptoms to come and go in phases. This is known as flare and remission. If the patient is a child, then development is also common.

There is also a link between stress and immune system disorders. People diagnosed with anxiety, depression and/or post-traumatic stress disorder (PTSD) often suffer from autoimmune diseases such as arthritis (RA), celiac disease or type 1 diabetes.
