The immune system is a network of cells, organs, and tissues that helps the body fight off infections and other diseases. An infection occurs when a germ, such as a bacterium or virus, invades the body and multiplies while attacking it.
The immune system is made up of several different components, each with its own function:
- Skin: acts as a barrier, keeping germs from entering the body.
- Mucous membranes: moist inner linings found in certain body cavities or organs, generally serving to trap or fight off germs.
- White blood cells: fight off germs that have entered the body and are produced with the help of antibodies.
- Lymphatic system organs and tissues: made up of organs such as the spleen, lymph nodes, and bone marrow, responsible for producing, storing, and transporting white blood cells.
What Are Immune System Diseases?Although the immune system exists to fight off disease, it can also develop its own conditions.
Sometimes the immune system triggers a response when there’s no real threat, which can present as asthma, allergies, or autoimmune diseases.
The immune system can also malfunction and develop immunodeficiency disorders, which cause a person to get sick more often, take longer to recover, or experience more severe illness than usual. This often results from a genetic disorder.
There are also diseases that directly attack the immune system itself, such as HIV, which destroys the body’s white blood cells.
Different Immune System DiseasesThere’s a wide range of immune system diseases and disorders that can occur, generally classified into two categories:
- Defects in overall function: this includes immunodeficiency diseases, which are extreme cases that result in severe or recurring infections that can be life-threatening. These occur more frequently in children, but can also affect adults, and aren’t always easy to treat.
- Malfunctioning immune response: when the immune system functions in an uncoordinated way, it can cause damage to the person’s own tissues, potentially resulting in conditions such as type 1 diabetes, rheumatoid arthritis, lupus, leprosy, autoimmune thyroiditis, primary biliary cirrhosis, or autoimmune hepatitis, among others.
Treatments for the Immune SystemSince there are so many possible causes behind immune system diseases, a wide range of treatments is also needed. Some are used therapeutically to modify a person’s immune mechanisms, such as monoclonal antibodies, fusion proteins, soluble cytokine receptors or recombinant cytokines, small-molecule modulators, and cell-based therapies.
In addition, when possible, it’s also important to address the root cause behind the immune system’s malfunction. Because of this, receiving proper, individualized medical care is essential for each case.
Preventive Steps to TakeWhile not every immune system disease can be prevented, there are steps each person can take to help reduce the risk of developing one:
- Healthy diet: always key to overall health, eating well gives the immune system the energy and micronutrients it needs to function properly.
- Exercise: physical activity supports muscle development and helps reduce stress, but it can also improve immune function by boosting overall circulation and helping immune cells move more efficiently throughout the body.
- Hydration: lymph, a fluid in the circulatory system that transports immune cells, is made up largely of water.
- Sleep: many important bodily processes happen during sleep, including the production of molecules that help fight infections.
It’s also important to maintain regular medical checkups to help catch any of these conditions early, if they occur, making treatment easier and, in some cases, preventing the disease from progressing.
