To put it simply, antigens are any foreign bodies or toxins that initiate an immune response in the body. Antibodies are proteins produced by the body to fight against these antigens. Let us just assume our body’s immune system and its response as an interesting drama that plays as long as we live. Now, certainly, it should have some main characters without which the drama never unfolds.

They circulate through the blood vessels and lymphatic vessels and do a constant patrol every time so that our body is always ready to fight any foreign body. WBCs are mainly 2 types: Phagocytes Lymphocytes Phagocytes As the name suggests, these cells engulf and absorb the pathogens, just like that! Remember the terms Neutrophils

But your thyroid may not be the underlying cause of your symptoms. It is estimated that 90% of those conventionally diagnosed with hypothyroidism actually have Hashimoto’s disease, also known as chronic lymphocytic thyroiditis. It is an autoimmune disease which means the body mistakenly attacks its own tissues. In the case of Hashimoto’s thyroiditis, the immune system infiltrates and damages the thyroid gland, a small butterfly-shaped gland at the front of the neck. Specifically, immune cells produce proteins called antibodies that capture and neutralize substances required for the production of thyroid hormone. The resulting low levels of thyroid hormone lead to the development of a wide arr
