How to increase Immunity? (Thymus Gland)
Thymus is a gland which forms a part of the immune system. It is known as a gland because it secrete hormone which contributes to the working of the immune system. It is a small gland shaped like a light pink colored moth ( it has two lobes which resemble the folded wings of the insect) sitting between the two lungs right under the sternum, or the breast bone.
Thymus gland is present in children, attains it maturity in the teen years and begins to shrink and finally disappear tin adults. Very rarely this gland can be found located elsewhere, neck, thyroid gland, or on the lungs. Its name comes from its resemblance to the leaf od the thyme plant; a triangular shape with one side representing the arches of its two lobes.
The thymus gland works in coordination with the lymphatic system (similar to tonsil, and adenoids) of the body which plays a crucial role in the defending the body against foreign matter, microbes and disease causing agents like bacteria, and virus.
The tissues forming the thymus gland are arranged into lobules, each lobule has a upper surface called the cortex, and an inner core called the medulla. A special type of cells known as T cells take birth in the bone marrow and are transported to the thymus gland via blood circulation.
These T cells are trained inside the thymus gland on differentiating between harmful, disease causing agents, and the no harmful tissues of the body. This training is important as without it the T cells can destroy the tissues of which the body is made of.
The T cells first enter the cortex of the lobules of the thymus gland where they are trained to identify the antigens produced by the harmful foreign agents. Only the T cells which can identify this successfully are selected (positive selection), whereas the ones which fail are discarded.
Thymopoietin and thymulin are the two hormones which act like trainers which provide the training to the T cells. The selected cells from the cortex enter the medulla where they are trained not to recognize the body’s own antigens which are not to be destroyed (negative selection).
The cells which fail the negative selection process are also eliminated as they may attack the body’s own cells known as autoimmunity. The cells which pass the final selection in the medulla are treated with the hormones of the thymus gland as a final training, after which these cells are released into the system to begin their job.
Thymosine is the hormone produced by the thymus gland which provides strength to the immune response of the T cells, it also plays a role in stimulating the pituitary gland for producing the growth hormone. As soon as the T Cells , or T lymphocytes recognize the harmful foreign agent cell they lock on to its surface via a special contact point and kills it.
The process of ageing has been found to be linked to the vanishing of the thymus gland with years. Thymic cysts, Tumors of the thymus gland are two of its important disorders which need serious consideration.
