elixir [45]

They also induce apoptosis. Radiation therapy is a cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors. The radiations also induce apoptosis. Cancer cells whose DNA is damaged beyond repair stops dividing and die. The damaged cells die, they are broken down and removed by the body.

In immediate hypersensitivity, the initial exposure to an allergen usually does not produce any symptoms. the symptoms, such as
stepladder [879]
During the initial exposure to the allergen, contact is made with B cells, these B cells differentiate and produce IgE antibody. The IgE antibodies which works against the allergens are released into the blood stream where they binds to Fc receptors which are located on mast cells and basophils. Now, the mast cells has become sensitized and they will wait patiently for the second exposure. When contact with the allergen is made the second time, the allergen becomes attached to the IgE present on the mast cells and this result in degranulation which trigger a lot of allergic responses.
