Properties of allergens

 a. Allergens are either protein or glycoprotein in nature, with multiple antigenic sites.

 b. Many allergens have intrinsic enzymatic activity that affects the immune response.

c.  Many allergens contain potential pathogen associated molecular patterns.

d.  Many allergens enter the host via mucosal tissues at very low concentrations, which tend to predispose the individual to generate TH2 responses, leading to B-cell secretion of IgE.
