them to the attention of lymphocytes so that thev can mount their attack. How lymphocytes recognize antigens A lymphocyte is different from all other cells in the body because it has about 100,000 identical receptors on its cellular membrane that enable it to recognize one specific antigen. The receptors are proteins containing grooves that fit into patterns forrned by the atoms of the antigen molecule --- somewhat like a key fitting into a lock --- so that the lymphocyte can bind to the antigen

B lymphocytes and T lymphocytes, play prominent roles in defending the body against specific pathogens and are involved in the adaptive immunity. Unlike the cells of the innate system, B cells have various isomers. One form of B cells (plasma cells) produces the antibodies

Drinks A majority of your drink intake should be soley water. However, teas, milk, and all natural juices are great too. I am an avid seltzer drinker and I like to flavor it with fresh citrus fruits like oranges, lemons, and limes. There are many great teas that taste great. I like to drink green tea and chai tea. However be very careful to watch out for teas with added sugars, just stick to tea bags and loose tea. As for milk, if you do not want to drink regular milk, coconut milk and almond milk

Host defence comprising many biological structures and processes within an organism that protect against various diseases is known as immune system(97). Immune system can be classified broadly in two sub-systems, the innate immune system versus the adaptive immune system, or humoral immunity versus cell mediated immunity. In humans, the blood-brain barrier, blood-cerebrospinal fluid barrier separate peripheral immune system from the neuroimmune system which protects the brain(98). Malfunctioning

1. Antibody immunity uses B cells to secrete antibodies. The antibodies are circulated through the plasma cells in the body and bind to the transplant. They then attack the transplant because they see it as a foreign body. Cell-mediated immunity also works to attack the "foreign body" but is uses T cells that are directly attached to the transplant. This eliminates the infected cell" before it has time to multiply. (Alberts, B. 1970) 2. Your immune system is constantly working to fight off foreign

they are needed. There are six families of leukocytes that have distinct roles in the body’s defense. These are the monocyte-macrophages, dendritic cells, mast cells, granulocytes, lymphocytes, and natural killer cells. All the leukocytes except the lymphocytes are considered part of the innate immune system. Lymphocytes are the only leukocytes associated with

also known as lymphocytes,

afflicting approximately 332,000 Americans each year. Lymphoma is distinguishable by the uncontrolled growth of lymphatic cells known as lymphocytes. A type of Lymphatic cancer is Central Nervous System Lymphoma, or simply CNS lymphoma. CNS lymphoma can be described as a form of non-Hodgkin lymphoma, which is characterized by the invasion of cancerous lymphocytes into the central nervous system. Once malignant cells invade the central nervous system severe damage can occur. The structures affected

cells, and your blood typically contains a percentage of each type. White blood cells initiate in the bone marrow but circulate throughout the bloodstream. There are five major types of white blood cells: These five include neutrophils, monocytes, lymphocytes, eosinophils and basophils.

it turns out that stress actually makes us more vulnerable to disease. Within the body, we have lymphocytes which help secrete stress hormones. One of the major lymphocytes, B lymphocytes, play an important role in fighting bacterial infections while T lymphocytes help fight cancerous cells, viruses and foreign substances. When our body is under attack, in terms of stress-related issues, the lymphocytes take over and try their hardest to fight off the diseases and foreign substances. Furthermore,

affecting the immature lymphocytes that is fatal within weeks if left untreated. Leukemia cells are aggressive, rapidly reproducing, and do not mature appropriately. There are two types of ALL based on the affected lymphocytes, B lymphocytes or T lymphocytes. B lymphocytes are important to the immune system as they protect the body from invaders (e.g., viruses, bacteria, fungi) and make antibodies that tag these intruders and trigger the immune system to destroy them. T lymphocytes can directly destroy

because there is where the lymphocytes, white blood cell place as it is the main key of the immune system. Then, all the structure or organs of the immune system placed in the body. For example is the bone marrow. The bone marrow is the source of the blood cells include the white blood cells that are play an important role in immune system. The bone marrow has the soft tissue located at the center of bone. Next one is the thymus. Thymus is the place where the T lymphocytes matured. There is alos lymphatic

This may be due to a defect in suppressor T-lymphocyte function.  Three types of autoantibodies: a) Thyroid-stimulating immunoglobulins TSI are IgG antibodies that resemble the TSH and act as receptor agonist. They bind to and activate the thyrotropin (TSH) receptor. This results in hypertrophy (increase

There is a difference in response to the pathogen by different individuals, causing varying symptoms and prognosis. Following are two very different examples which demonstrate how two different sub categories of people (children and pregnant woman) in native Liberia can respond differently to the pathogen. Children: Malaria is the leading cause of child death in Liberia, with one in three children under 5 testing positive to the disease (LMIS 2009.) The predominant form of Malaria in Liberia is

including, cultural, genetic and environment factors (3). As an autoimmune disease, rheumatoid arthritis occurs when an individual's own immune system attacks the synovial membrane - the soft tissue between joints (1). More specifically, B-lymphocytes, CD4+ T-lymphocytes, and macrophages penetrate the synovium and organize into distinct lymphoid masses with germinal centres (2). Swelling of the lining results from a dramatic increase in the number of macrophages and fibroblasts in the synovial fluid, as

Lymphadenitis Lymphadenitis is the result of swollen lymph nodes due to an infection. Due to the large number of microbes that are collected from tissue fluid and circulate in the lymph vessels, the macrophages present in the lymph nodes may not be able to ingest them as they may be too large, thus leading to the enlargement of the lymph node. When a lymph node become infected, they are usually a lot more noticeable due to the increase in size, the lymph nodes becomes tender and are felt in other

Immune System, which the cell attacks, is responsible for warding off enemies from the body. It consists of many parts, most notably lymph nodes, white blood cells, and lymphocytes.. When an infection is spotted, white blood cells swarm it and attack it. If the white blood cells cannot handle the infection, lymph nodes create lymphocytes, which attack the infection with renewed force, and help prevent infection in the future (Human Biology 149). The Yertis Pestis bacteria cell is a bacteria cell, which

the system which is involved in homeostasis in our body by draining the interstitial fluid. It is also in charge of defending our bodies from diseases. This is because the lymphatic system provides the place for formation and maturation of the lymphocytes which the white blood cells involved in immunity which are activate when they are in contact with antigens. Also the lymphatic system stops fluid form building up in the tissues in our body and its acts as a filter for the blood and removes the

cannot keep up with all the damage caused by the smoke. In fact, new research shows that once weakened, the immune system may not even be able to send out antibodies to kill simple bacteria. Malnutrition can also cause surgical site infection. The T-lymphocyte response has been associated with protein malnutrition, which is usually go along a deficiency of vitamins and other micronutrients in the body. The immune system is built of numerous types of white blood cells that have different functions in the
