Can Immunological Dysfunctions Contribute to the Causes of Parkinson’s?
Parkinson’s is a degenerative disorder affecting the brain. It develops when cells in the nerves and the brain are damaged due to the effect of aging or other factors resulting in the impairment of their functions. Damage to the cells eventually results in their destruction. Though advancing age is the most common risk factor for this disease, immunological dysfunctions have also been shown to contribute to the causes of Parkinson’s.
A weak or improperly functioning immune system can result in premature degenerative changes in the brain and the nerve cells.
Fine tremors of the hands and fingers are often the first visible sign of Parkinson’s disease. Over a period of time, patients develop other symptoms such as involuntary shaking, slowed movements, muscle stiffness, and an inability to maintain balance.
If the condition is not controlled properly, patients may have a difficulty in performing routine activities such as talking or having a conversation, walking, and getting dressed.
Hence, it is important to identify the immunological causes of Parkinson’s and correct the underlying abnormality to ease the symptoms. This article is focused on providing information about how an improperly functioning immune system can trigger the development of Parkinson’s disease.
How Does the Immune System Contribute To The Causes Of Parkinson’s?
Microglia Activation
Parkinson's disease is a progressive disorder characterized by degenerative changes in the dopamine neurons in the nervous system. Activated glia, due to the improper response of the immune system, has been found to play a role in hastening the degeneration of the dopaminergic neurons. Degenerative changes occur due to the secretion of an array of chemokines, cytokines, and reactive oxygen species that are regulated by the immune system. Hence, the faulty immunity of a person and microglia activation are considered to be the common causes of Parkinson's disease.Corticotropin-releasing Factor
Research studies have shown that the functions of the Corticotropin-releasing factor, which is known to help in coordinating the autonomic, endocrine, and immune responses of a person to stress, are hampered in patients with Parkinson’s disease. This can trigger an exaggerated immune system response by the body resulting in inflammatory changes in the brain tissues thereby triggering the causes of Parkinson’s disease. Also, the affected brain cells of patients diagnosed with Parkinson’s disease have been shown to possess Lewy bodies or deposits consisting primarily of abnormal forms of the protein, alpha-synuclein. These proteins can trigger an abnormal immune response, which indicates the connection between the development of Parkinson's disease and the abnormal functioning of the immune system.
