this study, the host immune response in the bursa of Fabricius, an organ mainly colonized by B lymphocytes, was assessed upon infection by the avian virus NDV genotype VII IBS002 and genotype VIII AF2240. The cell population in the chicken bursa was evaluated by flow cytometry and the results showed that in normal chickens, this organ was predominantly occupied by B lymphocytes while the T lymphocyte and macrophage populations were at minimal cell numbers. Different from the cell population…

The death of an elderly man on a flight from Beijing to Brisbane has been brought to our attention, as it appears the death was the result of an infectious disease, which we believe may have been ‘severe acute respiratory syndrome’ (SARS). SARS is a respiratory illness produced by a coronavirus, called ‘SARS-associated coronavirus (SARS-CoV). It was first identified in 2002 in southern China, which resulted in an epidemic in 37 countries, with more than 8000 cases and 774 deaths. The epidemic…

Etiology & Incidence: In the US, the third most common gastrointestinal illness requiring hospitalization and the leading indication for elective colon resection is diverticulitis. Of the people who have diverticulosis, 4-15% of the patients will develop diverticulitis, and increasing with age. An older belief was diverticulitis was caused by an obstruction of the diverticula (fecaliths), current belief is it is related to pressure or inspissated particles in the lumen. Other things believed to…

Components Of Blood Blood is a specialized body fluid. It has five main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, transporting oxygen and nutrients to the lungs and tissues, forming blood clots to prevent excess blood loss, carrying cells and antibodies that fight infection, bringing waste products to the kidneys and liver, which filter and clean the blood, and regulating body temperature. The blood that runs through the veins,…

natural microbiota or flora is a secondary defense system. Our body’s second line of defense against pathogens is natural, killer cells, phagocytic whole blood cells and fever. The third and final line of defense for our bodies are the specialized lymphocytes, which are T and B cells. We also develop antibiotics as a means of protecting ourselves…

that she has leukemia cancer, and has a few months to live. When Anna was a baby her parents kept taking her body parts and donating it to Kate's body to keep her alive. For example, during trials her mother confessed to Campbell that she took lymphocytes from Anna's Body and transferred it to Kate’s body. At the same time, she also mentioned about taking granulocytes from Anna's Body when she was six years old. During this process the doctors had to insert one or two thick needles in her bone…

cell-mediated responses of adaptive immunity. The adaptive immune response seems to have engrafted specific antigen recognition by highly diversified receptors onto innate defense systems, which have a central role in the effector actions of both B and T lymphocytes. The vital role of adaptive immunity in fighting infection is illustrated by the immunodeficiency diseases and the problems caused by pathogens that succeed in evading or subverting an adaptive immune response. The antigen-specific…

to create a more powerful treatment regimen when the effects of SLE remain critical and activity of the malfunctioning immune system is high. These drugs are designed to reduce the activity of the immune system in its entirety, suppressing the lymphocytes so that the body is forced to stop attacking its own tissues. This will result in fewer autoantigen-antibody complexes, lessening the buildup of these immune complexes in the body’s tissues. Thus, there will be less inflammation and less damage…

blood cell count, however the results can suggest it’s a strong possibility. Also the lymphocytes are also looked at, where if a patient shows more than 20 percent atypical lymphocyte, infectious mononucleosis is fairly likely and further diagnosis is to confirm this is not needed. With this patient is was shown that his white blood cell count was above normal range and had more than 50 percent of his lymphocytes showing atypical lymphocytosis. When compared to other research, this confirms the…

invades and kills certain types of cell that are crucial in the prevention of disease in the immune system. More specifically, they target T-helper cells, which are a type of lymphocyte. The T-helper cells act to produce and release cytokines, which stimulate various immune responses e.g. interleukins trigger B lymphocytes to differentiate into plasma cells which produce antibodies that are crucial in fighting disease. When the numbers of these T-helper cells fall below that needed to…
