Do mast cells release histamine as a result of the allergen-antibody reaction?
Yes, mast cells release histamine in response to the allergen-antibody reaction. When an allergen binds to specific antibodies on the surface of mast cells, it triggers the release of histamine and other inflammatory mediators, leading to allergy symptoms.
What antibody is produced in a reaction to an allergen?
The antibody is specific to the antigen (allergen). Different antibodies are produced at different times of exposure (IgM=acute; IgG=longterm) or in different systems of the body (IgA is produced in the gut).
What is the root in the word allergen?
The root in the word "allergen" is "allerg," which is derived from the Greek word "allergein," meaning "to react to differently."
Is Allergies a disease?
No, they are a heightened sensitivity to a substance (allergen) to which most people do not react.
What is RAST?
In radio-allergosorbent allergy testing (RAST), a patient's blood serum is combined with allergen in a test tube to determine if serum anti-bodies react with the allergen.
Why does penicillin allergy occur?
The beta-lactam ring of penicillin can react with the polypeptides' terminal amines on lysine residues. This results in the formation of an allergen. A person's immune response will be triggered when he or she is exposed to this allergen.
Will type A blood react with anti-A antisera?
No because type A blood has antibody for B
As a result of an allergen-antibody reaction?
An allergic reaction is triggered by later encounters with the same allergen, which promptly binds and cross-links the IgE antibodies on the surface of the mast cells and basophils. This event includes an enzymatic cascade that causes the mast cells and basophils to degranulate, releasing a flood of histamine and other inflammatory chemicals that together induce the inflammatory response typical of allergy. page 798 anatomy and phisiology eighth edition
What happens when antibody A reacts with B plus blood?
Antibody A is anti-B. So when these react, the RBC agglutinate and hemolysis occurs. Expect acute renal failure and death.
The clumping of cells that occurs as a result of an antigen-antibody reaction is called?
When an antigen and antibody react it causes cells to clump together. The term used to describe the clumping of cells is called agglutination.
What can people be allergic to?
Almost anything can become an allergen or trigger if you have the health predisposition. You may react to just one thing, you may react to several things, or you may react to most things (what is known as a 'universal reactor'). The allergen/triggers can be foods, food additives, even water, or non-foods such as animal hair, house dust mite, chemicals, etc. In fact, you can have an allergy/allergies and/or intolerance/intolerances and/or sensitivity/sensitivities to anything under the sun, including the sun.yes. it is something someone can be allergic to
Is glycoprotein an antigen or antibody?
