Study Notes

Hypersensitivity Types

Type I hypersensitivity involves basophils and mast cells sensitized by IgE.
Type IV hypersensitivity is characterized by delayed reactions, and the main immune response involved is cellular immunity.

Immune Response

Type I, II, and III hypersensitivity involve antibody-mediated immunity as the main immune response.
Type IV hypersensitivity, on the other hand, involves cell-mediated immunity as the main immune response.

Antigen-Antibody Complexes

Type III hypersensitivity involves the formation of antigen-antibody complexes.
