Immunoglobulins, Thyroid-Stimulating

Hormone, Cytokines Immunoglobulins are proteins produced by our immune system to help protect us against infectious diseases. They recognize and bind to the molecules that cause infection and activate other components of the immune system to fight off the infection. Immunoglobulins are an important part of the body's defense mechanism, and deficiencies in immunoglobulins can make us more vulnerable to infections. Thyroid-Stimulating Hormone (TSH) is a hormone produced by the pituitary gland that stimulates the thyroid gland. It regulates the production of thyroid hormones which influence growth, metabolism, and digestion. High or low levels of TSH can indicate an imbalance in thyroid hormones and can be used for diagnosis and management of thyroid disorders. Cytokines are small proteins released from cells that act as messengers between cells and organs. They regulate the activities of the immune system, cell growth and differentiation, and the maintenance of tissue integrity. Abnormal levels of cytokines can contribute to numerous disorders of the immune system and other conditions, such as cancer and autoimmunity.
