The IGHMBP2 gene provides instructions for making an enzyme called immunoglobulin mu DNA binding protein 2 (IGHMBP2). This enzyme functions as a helicase, which means that it attaches to particular regions of DNA and temporarily unwinds the two spiral strands of these molecules. When a cell prepares to divide to form two cells, the chromosomes are duplicated (replicated) so that each new cell will get a complete set of chromosomes. The replication process involves unwinding the DNA so that it can be copied. This mechanism is also involved in the production of RNA, a chemical cousin of DNA. Additionally, the IGHMBP2 protein is thought to be involved in the production of proteins from RNA through a process called translation. The IGHMBP2 protein is produced in cells throughout the body.

Bornholm disease
Bornholm disease is an illness which causes flu-like symptoms, together with pain in the chest or tummy (abdomen). Young babies are most at risk of serious complications. Babies may need preventative treatment (immunoglobulin) to help prevent complications. What is Bornholm disease. The recommended treatment is called immunoglobulin. This is given.

The immune system
This leaflet gives a brief overview of the immune system and how it works. A person with a weak immune system might have difficulty fighting off infections. In autoimmune diseases the body is unable to tell what is its own and what is foreign, so it attacks itself. Autoimmune diseases can attack any part of the body - eg, type 1 diabetes.

Toxoplasmosis
How is toxoplasmosis diagnosed. If you are suspected of having toxoplasmosis, the first test you are likely to be offered is a blood test. This will show that the levels of proteins (immunoglobulins) produced by the immune system to fight infection will be high. There are various types of immunoglobulins. IgG level rises in the first 1-2 weeks of.

Allergies are the body's response to a substance called an allergen. These may be harmless substances for the majority of people, but for some, the person's immune system reacts to the allergen, causing an allergic reaction. A person is exposed to the allergen.
