Estudo sobre Células Dendítricas (Denditric Cells-DC)

What is DC Therapy?
Dendritic Cell (DC) Therapy or so-called Dendritic Cell vaccine is a newly emerging and potent form of immune therapy used to treat cancer. Only recently (2010) approved by the US FDA, dendritic cell therapy is an immune therapy which harnesses the body's own immune system to fight cancer. The dendritic cell itself is an immune cell whose role is the recognition, processing and presentation of foreign antigens to the T-cells in the effector arm of the immune system. Although dendritic cell are potent cells, they are not usually present in adequate quantity to allow for a potent immune response. Dendritic cell therapy thus involves the harvesting of blood cells (monocytes) from a patient and processing them in the laboratory to produce dendritic cells which are then given back to a patient in order to allow massive dendritic cell participation in optimally activating the immune system. To learn more about vaccine and dendritic cell therapy for cancer, please read the following articles:

  1. Glycomet GP 2 is a blend medication that builds the measure of insulin your body produces. The insulin at that point attempts to bring down your blood glucose level. It is generally required once every day. You should continue to take it however long it is recommended.
