Sensitization Cross

Cross sensitization is a process in which the body's immune system reacts to antigens that have common determinants (parts of the molecule) with the allergen that caused sensitization (hypersensitivity) earlier. This occurs when the antigen that causes sensitization and the antigen to which sensitization occurs have common determinants.

In cross-sensitization, the immune system may react to an antigen that shares common determinants with the antigen that previously caused sensitization. This can lead to allergic reactions such as itching, hives, swelling and difficulty breathing.

Cross-sensitization is one of the mechanisms that can lead to cross-sensitivity, which manifests itself in the form of allergic reactions to different allergens. For example, if a person is sensitized to pollen, they may also be cross-sensitized to animal hair, such as cats and dogs, or to foods, such as peanuts and wheat.

To prevent cross-sensitization, it is necessary to avoid contact with allergens that have common determinants, and also use antiallergic drugs, such as antihistamines, to reduce allergic reactions.

Overall, cross-sensitization is an important mechanism that can lead to various allergic reactions, so it is important to be aware of possible allergens and preventive measures.

Cross-reactivity sensitization Sensitization not based on an antigen epitope for one's own antihistamine antibody. This type of sensitization occurs when the atopic response is initiated by one "example" (sensorimotor immunity) and then antigenic
