What is the definition of Leukemia?
ANSWER:----------
A very serious disease in humans and other warm-blooded animals in which the bone marrow and other blood-forming organs produce increased numbers of immature or abnormal leucocytes. These suppress the production of normal blood cells, leading to anaemia and other symptoms .we can also say Leukemia is a malignancy cancer of the body's blood-forming tissues, including the bone marrow and the lymphatic system.Leukemia usually involves the white blood cells. Your white blood cells are potent infection fighters — they normally grow and divide in an orderly way, as your body needs them. But in people with leukemia, the bone marrow produces abnormal white blood cells, which don't function properly.
How would a blood smear appear differently in a leukamia patient?
ANSWER:-------
A complete blood count (CBC) is done to determine how many blood cells of each type are in the blood.In leukemia an increase in white blood cells (leukocytes) which grow uncontrollably and crowd out the other blood cells. So, to put it in simple terms, we should see more than a usual amount of white blood cells. Genetical aberrations(POINT MUTATIONS,CHROMOSOMAL VARIATIONS ETC)
What is the function of Eosinophil, Monocytes, and Lymphocyte?
ANSWER:----
Eosinophil:-The eosinophil is a specialized cell of the immune system. Eosinophils are a specific type of white blood cell that protects your body against certain kinds of germs, mainly bacteria and parasites. They're also what causes you to have allergic reactions.This proinflammatory white blood cell generally has a nucleus with two lobes (bilobed) and cytoplasm filled with approximately 200 large granules containing enzymes and proteins with different (known and unknown) functions.
functions:- Transport oxygen bound to hemoglobin molecules; also transport small amount of carbon dioxide
Eosinophils is to respond to and destroy parasitic worms such as pinworms, hookworms, tapeworms and flukes.allergic response & attack parasites
Kill parasitic warms; increase during allergy attacks; might phagocytize antigen-antibody complexes and inactivate some inflammatory chemicals Eosinophils release digestive enzymes from the granules in their cytoplasm onto the surface of the worms there by destroying them and digesting away their remains and also phagocytosis and clean up some of the debris from the damage they caused.Eosinophils are also involved in allergic responses and in the reactions involved in asthma. As a parasite enters the body, a chemical signal is sent out that the eosinophils recognize and tells them exactly where the intruders are located. When arriving to the site, one task they can perform is to completely engulf parasites. This is like you swallowing a large amount of food without chewing! It's definitely an effective way eosinophils can defeat these germs.
in brief its function Kills Parasites, Also involved in inflammation and allergic reaction ,Releases histamine during allergic reactions and Common is asthma.
Monocytes:- These are phagocytic which means eat dead or dying tissue- neutrophils.these cell regulate inflammatoryresponce
function:-phagocytosis, antigen presentation, and cytokine production.
Monocytes make it easier for the immunie system to function against the antigenPhagocytosis of large particles; typhoid, malaria, mononucleosis. The Monocyte activates the T lymphocytes cells.eat up large particles Active phagocytes that become macrophages in the tissues; long term "clean up team"; increase in number during chronic infections such as tuberculosis
Lymphocyte role is to attack infections, virus & early stage cancer Part of immune system; one group(B lymphocytes) produces antibodies; other group(T lymphocytes) involved in graft rejection, fighting tumors and viruses, and activating B lymphocytesrespond to foreign invaders in the body. Some lymphocytes work alone, while others are able to coordinate with other cells.
Ques:- In Neutrophils, what organelle is represented as neutral stained granules (Hint : This organelle is necessary for the digestion of engulfed micro organisms).
In neutrophils , three-lobulated nucleus is represented as neutral stained granules are small and abundant. They are represented as neutral staining granules. This granulocyte has very tiny light staining granules very difficult to see. The nucleus is frequently multi-lobed with lobes connected by thin strands of nuclear material. These cells are capable of phagocytizing foreign cells, toxins, and viruses.
Cells divide and are dumped into the blood stream and lymph fluids to combat the infection where They eat bacteria and other foreign matter.The neutrophil membrane wraps around the invader and traps it inside the neutrophil where digestive enzymes in the neutrophil destroy the invader. Body is responding as expected to an infection is judged in a new and young cell , by counting the percentage of neutrophils that have a single, intact nucleus because new cell divide into pieces as they age,
The cytoplasm of neutrophils contains three types of granule.
Primary granules are non-specific and contain lysosomal enzymes, defensing, and some lysozyme. The granules are similar to lysosomes. They stain violet color when prepared with Wright's stain which is commonly used in studying the blood. The enzymes produce hydrogen peroxide which is a powerful anti-bacterial agent.
Secondary granules are specific to neutrophils and stain light pink ('neutral stain'). They contain collagenase, to help the cell move through connective tissue, and lactoferrin, which is toxic to bacteria and fungi.
Tertiary granules have only recently been recognized. It is thought that they produce proteins which help the neutrophils to stick to other cells and hence aid the process of phagocytosis.
neutrophils respond to chemicals (called chemotaxins which are released by bacteria and dead tissue cells) and move towards the area of highest concentration ,they die after phagocytosis and release all the remnants of their enzymes cause liquefaction of closely adjacent tissue. This results in an accumulation of dead neutrophils, tissue fluid and abnormal materials known as pus
