Hypersensitivity and Immune Response Quiz

Study Notes

Hypersensitivity

Hypersensitivity refers to an exaggerated immune response that can cause tissue damage and various pathological conditions.

Immunoglobulins

Immunoglobulins, or antibodies, are specialized proteins produced by B cells that play a crucial role in identifying and neutralizing pathogens like bacteria and viruses.
There are five main classes of immunoglobulins: IgA, IgD, IgE, IgG, and IgM, each with distinct functions and locations within the body.

Immune Response

The immune response is the body's method of recognizing and combating foreign invaders, such as pathogens, toxins, and cancer cells.
It involves both innate (immediate) and adaptive (delayed) mechanisms, coordinating various cells and proteins to protect the organism.

Immunosuppression

Immunosuppression is a decrease in the effectiveness of the immune system, which can result from medical interventions (like organ transplants), diseases, or certain drugs.
It makes the body more susceptible to infections and can impact the ability to fight off diseases.

Immunotherapy

The purpose of immunotherapy is to enhance or restore the immune system’s ability to fight cancer and other diseases by using substances derived from living organisms.
It can involve the use of monoclonal antibodies, vaccines, or immune checkpoint inhibitors.

Natural Immunity

Natural immunity includes the innate immune responses that provide the first line of defense against infections, consisting of various cells such as neutrophils, macrophages, and natural killer (NK) cells.
It plays a vital role in recognizing and responding to pathogens rapidly and without prior exposure.
