  • The immune system is made up of non-specialised defences such as your skin (acting as a barrier) and strong acid stomach juices.
  • Here the immune system is suppressed leaving the vulnerable to illness.
  • Lymphocytes are divided into T cells and B cells.

You may need to stay in the hospital during the early stages of the illness. On the opposite end of the spectrum, autoimmunity results from a hyperactive immune system attacking normal tissues as if they were foreign bodies, according to the University of Rochester Medical Center.

  • Allergy - when your immune system overreacts.
  • The scientifically interesting PIDs are by far outnumbered by acquired immune deficiencies, caused by factors such as chronic viral infections (such as HIV or hepatitis C), undernutrition, polytrauma, stress after surgery, diabetes, cancer of the lymph nodes, anesthesia influences and others.
  • In order to find out more about these complex interconnections and to make a gradual transfer to the clinical routine, specialized centers are needed in which interdisciplinary teams of pediatricians, internal medicine specialists, immunologists, molecular biologists, infectiologists, hematologists, and pathologists work closely together both to study the causes of PID and to develop novel treatment methods.

The immune system helps protect the body from harmful substances called antigens. Lymphocytes are found in your blood and also in specialised lymph tissue such as lymph nodes, your spleen and your thymus. This may happen with an allergic reaction.

To fight these off successfully, the body will need to resort to what is called the adaptive immune system (consisting of white blood cells of T cells and B cells). B cells mature in the bone marrow. B cells can recognise antigens that have never entered the body before and even man-made molecules that don't even exist in nature.

In a person affected by obesity (body mass index [BMI] of 30-39), studies have shown that it takes a more potent hepatitis B vaccine in order to come close to the response rate of a standard single dose therapy in an individual with a BMI less than 30 (overweight).


Some scientists are investigating whether ongoing stress takes a toll on the immune system. DiGeorge syndrome (thymic dysplasia) , a birth defect in which kids are born without a thymus gland, is an example of a primary T-lymphocyte disease.

Possible Complications

The immune system is always learning, which is why you don’t get infections or diseases so badly the second time. Some deficiencies cause early mortality (before age one), others with or even without treatment are lifelong conditions that cause little mortality or morbidity. These specialized proteins lock onto specific antigens. There are two types of white blood cells – lymphocytes and phagocytes. Immune system boosters and busters, in addition to strengthening the body, exercise causes the body to release endorphins that reduce stress levels.
