Type II hypersensitivity: Or cytotoxic reactions, are antibody dependent, IgG or IgM binds to the own body cell surface after being altered by a protein, so the immune system recognizes as non-self (foreign) attacks and destroys the cell by fixing a protein called complement, which in turn forms the Membrane Attack Complex and destroy the cell, the most famous is hemolytic anemias and some auto immune diseases

What is the difference between hypersensitivity and autoimmunity?

Dr. Robert Ramirez
Allergy and Immunology 18 years experience
Very different: A hypersensitivity is generally what we call an allergic reaction. This is mostly to things you find in the environment, and most of the time is driven by an antibody called ige. An autoimmune disease is usually driven by igg antibody, and what is being attacked is something in the body that the immune system thinks is "foreign" and should be "dealt with" when it shouldn't be.

What is the least cytotoxic root canal filler?

Calcium Carbonate: Gutta percha is the standard by which all root canal material are judged, and for good reason; it works over 90% of the time. However, it is cytotoxic. There is a system that uses calcium carbonate to fill root canal teeth, but there is not addquate evidence to say how well it works or if it is cytotoxic, but it is unlikely that it is cytotoxic.

Desensitization: Allergen desensitization does not work on all allergies--it is most effective with seasonal allergens, indoor allergens and insect bites.Insect bites from bees, red ants and wasps are treated with allergen desensitization.Allergen desensitization uses small amounts of the allergen the person is allergic to and injects the allergen into the individual's body.

What are t-helper cells/cytotoxic cells?

Lymphocyte family: These are a special group of white blood cells that actually kill cells that the body perceives to perhaps be infected. This is usually, but not always, a good thing. We pathologists recognize them as cd8+, staining brown with a special stain. I'm glad you're interested in the immune system, which still amazes scientists. Thanks for asking.

How do I solve my hypersensitivity to sound? Besides earplugs.

Dr. Deborah Wong
Family Medicine 34 years experience
Depends on diagnossi: Do you know why you are hypersensitive to sounds? This could be a neurological issue, it could be due to migraines, it you've had this all your life it could just be congenital. Is it one or both ears. If only one ear, could be something serious, a problem in that side of your auditory system, worse case scenario a tumor. Unlikely, but see your dr. To rule out something serious but treatable!
