Hello!
We are from Temasek Polytechnic,
taking this subject:
Principles of Biochemistry and Physiological for Nutrition.
And we are doing this blog
on a Severe Allergic reaction called
Anaphylaxis.
To cut the story short,
You will learn everything you need to know about Anaphylaxis here!

There are 2 Major Groups:IgE mediated: This form is the true anaphylaxis that requires an initial sensitizing exposure, the coating of mast cells and basophils
(cells in the blood and tissue that secrete the substances that cause allergic reactions, known as mediators)
by IgE, and the explosive release of chemical mediators upon re-exposure.
Non-IgE mediated: These reactions, the so called "anaphylactoid" reactions, are similar to those of true anaphylaxis, but do not require an IgE immune reaction.
They are usually caused by the direct stimulation of the mast cells and basophils. The same mediators as occur with true anaphylaxis are released and the same effects are produced.
This reaction can happen, and often does, on initial as well as subsequent exposures, since no sensitization is required.
This can be initiated in response to an allergen!And these include:Drug allergies
Food allergies
Insect bites/stings (E.g: Bee sting)
In the next post, we will be discussing more about these allergies!Citation: Common Agents involved in Anaphylaxis and their mechanisms
