19 Differences between Active Immunity and Passive Immunity

Differences between Active Immunity and Passive Immunity

Image Source: BioNinja. The major differences are: S.N. Characteristics Active Immunity Passive Immunity 1. Definition The protective immunity in which the individual’s own immune system is stimulated to produce antibodies and lymphocytes. The immunity in which a person receives antibodies or lymphocytes that have been produced by another individual’s immune system. 2. Exposure to Antigen Requires exposure to a pathogen or to the antigen …

Differences between Humoral Immunity and Cell mediated Immunity

Image Source: Pinterest. Here are some differences: S.N. Characteristics Humoral Immunity Cell-mediated Immunity 1. Definition The immunity mediated by macromolecules found in the extracellular body fluids is called humoral immunity. (“humor” a medieval term for body fluid) The immunity that identifies and destroys infected cells in the body is called cell-mediated immunity. 2. Mediator The main cell involved in humoral …

12 Differences between Primary and Secondary Immune Response

Differences between Primary and Secondary Immune Response

Differences between Primary and Secondary Immune Response In a primary immune response, naive B cells are stimulated by antigen, become activated, and differentiate into antibody-secreting cells that produce antibodies specific for the eliciting antigen. A secondary immune response is elicited when the same antigen stimulates memory B cells, leading to the production of greater quantities of specific antibodies that are …

12 Differences between antigen and antibody (Antigen vs Antibody)

Differences between antigen and antibody

Differences between antigen and antibody Antibodies are produced by the immune system in response to antigens (material perceived as foreign). The antibody response to a particular antigen is highly specific and often involves a physical association between the two molecules. This association is governed by biochemical and molecular forces. The reaction between antigens (Ags) and antibodies (Abs) involves complementary binding sites …
