Helper t cells do what?

Helper t cells do what?

Manage immunity: Helper T cells are unit commanders that instruct soldiers on the front lines. They help B cells secrete protective antibodies. They help "killer" T cells attack infected cells. They also influence the "flavor" of the immune response to favor more of an allergic-type response versus more of a flu-like response. They are CD4 positive cells that are destroyed in HIV/AIDS leading to immunodeficiency. ...Read more

What are helper T cells, killer T cells, and B cells?

What are helper T cells, killer T cells, and B cells?

Lymphocytes: Part of white blood cells, there are different types of lymphocytes, all look alike under the microscope, their functions differ, as their names imply, helper T cells orchestrate most of the immune system functions,killer T cells,are one of the first lines of body defence against invading microorganisms,and B cells' main function is to produce antibodies against microbes with the help of T cells ...Read more

What is hepatosplenic t cell lymphoma?

What is hepatosplenic t cell lymphoma?

A Rare Lymphoma: Hstcl is a rare cancer of the the white blood cells. It usually affects young men with a history of immunosuppression for other diseases like inflammatory bowel disease (uc and/or crohn's) or after an organ transplant. The bad cells usually grow in the liver, spleen and bone marrow. It is treated with chemotherapy and possibly a bone marrow transplant. It unfortunately can be difficult to cure. ...Read more

Which is worse, b cell lymphoma or t cell lymphoma?

Which is worse, b cell lymphoma or t cell lymphoma?

T-cell NHL: The prognosis for t-cell non-hodgkin's lymphoma (nhl) vs. B-cell nhl depends on multiple factors, but in general t-cell nhl has a worse prognosis. One reason is that b-cell, cd20+ nhl can be treated with the anti-cd20 monoclonal antibody Rituximab in addition to chemotherapy. We currently don't have such an effective, low toxicity antibody (biologic treatment) for t-cell nhl. ...Read more

What do T cells do?

Lymphocytes: T cells, different types, master the specific immune system, while B cells mainly produce different types of antibodies, under the the control T cells, to fight invading microorganisms and/or invading antigens, just simply put for a very complex system (the immune system) ...Read more

What does it mean if cd8 suppressor t cells are low?

What does it mean if cd8 suppressor t cells are low?

Weakness in defense: T cells help regulate the t cells and are the main reason people don't develop autoimmune diseases. T cells, if left unchecked, would attack the individual's own body .There are two main types of t cells, cd4 and cd8. Cd8 t cells are also known as killer t cells. Though this name sounds threatening, these are very important in preventing illness. These cd8 t cells kill kill infected and damaged c. ...Read more

What are T cells?

What are T cells?

Type of lymphocyte: When lymphocytes were first recognized as a small population of the white blood cells, Bob Good divided them into T and B cells. The T cells were matured in the Thymus and the B cells in the Bursa of Fabricius found in the chicken. The B cells produce antibody andthe T cells contain cells ie. Th 1, making IL2 and the Th2 IL 10. The TH 1 targets bacteria and viruses. ...Read more

What are B cells and T cells?

What are B cells and T cells?

White blood cells: B-cells make antibodies. Each single B-cell, after maturing by modifying its DNA, produces one type of antibody that is specific for a single target. If the body decides that it is a good antibody, the B-cell moves to the bone marrow making that antibody for years. Some T-cells kill damaged cells (eg after viral infection or pre-tumor cells). Other T-cells act as messenger guiding inflammation ...Read more

Do cell phones mess with brain waves?

Do cell phones mess with brain waves?

Not directly: The message, not the messenger, is more likely to affect your brain function. Power emission of cell phones is so low that alteration of brain electrical activity will not occur. Despite media concern, many studies have failed to conclusively document increase of brain tumors in cell phone users. The content of the phone call will affect your brain activity much more strongly than the phone. ...Read more

How do T cells defend the body?

Regulate immunity: T cells can be helper cells that help recruit the B cells and thus organize the production of immunoglobulins (antibodies) The cytotoxic cells are T cells that are involved directly in killing other cells such as cancer cells and virus infected cells ...Read more

Does high reticulocyte count mean sickle cell crisis?

Not necessarily....: Patients with sickle cell disease have elevated reticulocyte counts at baseline, as their red cells have significantly reduced half lives relative to normal rbcs. More rapid red cell synthesis, reflected by the high retic count, is needed to maintain steady state, albeit lower than normal. Are you having other symptoms suggesting vaso occlusive crisis? If so, you should seek medical attention. ...Read more
