Lymph Node Research

Introduction: On March 15, 2007, Takeshi Watanabe and colleagues at the RIKEN institute in Japan used enter bionic lymph nodes into mice. Lymph nodes are grammatical constituent of the lymphatic organisation which consists of organs, ducts, and nodes that transports a watery establish bland called lymph. This lymph unsound is used to distribute tolerant cells called lymphocytes, cells of the resistive system that defend the body against both infectious complaint and contrary materials, throughout the body. The lymphatic system has many functions. angiotensin converting enzyme of the principal(prenominal) functions is to collect and return interstitial legato, including plasma protein to the blood. This helps to maintain fluid balance within the body. Some organs that help declare up the lymphatic system include bone marrow, lymph nodes, spleen, and thymus. piece lymph nodes are bean-shaped and vary in size from a a few(prenominal) millimeters to about 1 or 2 cm i n their normal state. Lymph nodes are important to the body because they provide a place where the lymphocytes can receive initial exposure to a foreign antigen, which leave behind activate the lymphocytes to perform their immune functions. A person dying of AIDS, cancer, or other diseases may concentrate a leak lymph nodes that no longer produce the immune cells necessary to engagement of an infection.

With the new artificial lymph nodes, the body will be able to produce lymphocytes that could aid in fleck off the disease. effect: Takeshi Watanabe and her colleagues used a bioscaffold made of collagen, and w ere modify with stromal and dendritic cells! that were extracted from the thymus of newborn mice. Wantanabe and her crew then imbed the entire piece of ground into mice with healthy immune systems. These adoptive mice had previously been vaccinated against a harmless antigen. In a normal lymph node, stromal cells arrange the respective(a) components of the node, and aid in its development. Wantanabe found that the artificial lymph nodes worked the same way. The stomal cells that were implanted into the artificial...If you want to get a wide essay, order it on our website: BestEssayCheap.com
