Sensitization (2)

2.

Antibodies are a type of glycoprotein that exists in blood or body fluids and can specifically bind to antigens

Antibody, also known as immunoglobulin (Ig), is a large Y-shaped protein secreted by B lymphocytes

There is a lock-like structure called a paratope (antigen-binding site) at the top of two branches of the Y-shape on the antibody protein.

Figure 19-1 Binding of antibody and antigen

Although antibodies are used as an immune method against foreign bodies, some people (such as allergies) have autoimmune diseases caused by abnormal antibodies

Three, allergy

Allergy refers to a specific immune response that occurs when the body responds to certain antigens for the first time and is stimulated by the same antigen again.

Four, allergic reactions

Allergic reaction is an excessive reaction of the human body with an allergic constitution after being exposed to a certain substance.

Five, sensitization conditions

(1) Internal factors

Allergies are the internal factors of sensitization

Many substances are harmless to most normal people, but may be allergens to people with allergies

(2) External cause

1.

Allergens are the core external cause of allergic diseases

Ways allergens are inhaled into the human body, Formula ingestion, injection of formula (drugs), contact the like

Although not all foreign substances can cause sensitization, it may be an allergen for people with allergies

2.

Specific environmental factors such as climatic conditions, ventilation performance, process flexibility, operating habits, personal protection, etc.
