Flashcards

Innate Immunity

Nonspecific defense system present from birth, providing an immediate response against pathogens. Includes physical barriers, chemical mediators, and cellular defenses.

Dendritic Cells

Immune cells that act as messengers between the innate and adaptive immune systems. They capture, process, and present antigens to T cells to initiate an adaptive immune response.

Adaptive Immunity

A specific defense system that requires recognition of a foreign antigen before mounting a targeted response. It involves B cells and T cells. Also provides immunological memory.

Adaptive vs. Innate Immunity

Adaptive immunity is specific and develops immunological memory, whereas innate immunity is nonspecific and provides an immediate, but general, response.

Response to Non-Changing Antigens

Innate immunity provides a rapid, non-specific response to antigens that do not change. It relies on mechanisms that recognize general patterns associated with pathogens.

Study Notes

Types of Immunity

Innate immunity provides an immediate, nonspecific response to pathogens and is mediated by cells such as neutrophils, macrophages, and dendritic cells.

Characteristics of Immunity

Adaptive immunity requires recognition of a foreign antigen before producing a response, which takes time.

Key Features of Adaptive Immunity

The main characteristic that distinguishes adaptive immunity from innate immunity is the ability to recognize and remember specific pathogens, allowing for a more targeted response.
