Autoimmune disorders fall into two main ...

What is the immune system? The immune system is a means of body defense against "foreign" substances such as bacteria and viruses. It consists of two main parts. One component includes production, proteins that recognize "foreign" substances and cause them to be removed from the body. Another component involves specialized blood cells called T lymphocytes that can attack and kill a "foreign" substances directly. Antibodies and T-lymphocytes become protective only after they are lasix 40 mg daily "foreign" substance for the first time. This is the reason that we use

: that our immune system is weakened to admit or inactivated forms, and it can cause disease, so we will be protected if we actually come in contact with them. What are autoimmune diseases? Usually the immune system recognizes the tissue in the body that are not "foreign" and attack them.

Autoimmune disorders are diseases caused by the body produces an immune response against its own tissues. The cause of autoimmune diseases is unknown, but it seems that there is a genetic predisposition to the development of autoimmune diseases in many cases (such as they are passed from generation to families). In some types of autoimmune diseases (eg rheumatic fever), bacteria or viruses with the immune response and antibodies or T cells attack healthy cells because they are part of their structure that resembles the infection of the embryo. Autoimmune disorders fall into two basic types: those that damage many organs ("systemic") and those with only one >> << or tissue directly affected by the autoimmune process ("localized"). Some of the most common types of autoimmune diseases include:

In some cases, a person can have more than one autoimmune disease, for example, people with Addison's disease often diabetes mellitus type 1, while people with sclerosing cholangitis often or ulcerative colitis or Crohn's disease. In some cases, antibodies can not be directed at a specific organ or tissue, such as antiphospholipid antibodies can react with clotting proteins in bloood, which leads to the formation of clots in blood vessels (thrombosis). .
