An **immunostimulant** is a substance or treatment that enhances the activity of the immune system. This can be achieved through various mechanisms, including increasing the production of immune cells (such as lymphocytes and macrophages), improving the function of existing immune cells, or boosting the release of signaling molecules (cytokines) that coordinate the immune response. Immunostimulants are employed to strengthen the body's defense against infections, cancers, and other diseases where the immune system is suppressed or requires an added boost. They can be naturally derived (from plants or microbes) or synthetically produced, and administered through a variety of methods, including oral, intravenous, or topical applications.
Immunostimulant meaning with examples
- Following chemotherapy, the oncologist prescribed an immunostimulant to help boost the patient's depleted white blood cell count and reduce the risk of opportunistic infections. The treatment helped to reduce the fatigue of the cancer patient and they reported feeling more energetic during recovery. The immunostimulant was designed to get the patient back on track toward recovery after chemotherapy.
- Researchers are investigating new immunostimulants derived from marine organisms to combat viral infections, as these compounds may activate novel immune pathways. The scientists are researching how these marine derived immunostimulants can be used to protect from emerging diseases, such as the flu and potentially COVID, by providing a boosted immune response to those viruses. Their work is cutting edge.
- A vaccine functions as a type of immunostimulant by introducing a weakened or inactive pathogen to prime the immune system for future encounters with the live pathogen. These vaccines are a crucial tool to combat the spread of various diseases. Vaccination provides the body with the tools to prepare the body for the real threat, and this means that they are a life saving tool.
- In veterinary medicine, immunostimulants are used to treat various conditions in animals, such as immune deficiencies or certain types of cancers. Many pet owners see these products as an insurance policy, in the event of a dangerous disease. They are also designed to help protect against opportunistic diseases.
- Patients with chronic fatigue syndrome are sometimes treated with immunostimulants in an attempt to reactivate their immune function and improve their symptoms. These substances have helped many to get back to living a more normal life. Some patients report feeling better and more energetic after taking these immunostimulants.
