specific nonspecific immune response

Specific Immune Response

Also known as adaptive immunity, it is a targeted defense mechanism against specific pathogens or antigens.

Lymphocytes

Primary immune cells involved in the specific immune response, including T cells and B cells.

Antigen-Presenting Cells (APCs)

Cells such as macrophages and dendritic cells that present antigens to T cells.

Antibodies

Proteins produced by B cells that bind to specific antigens to neutralize them or mark them for destruction.

Humoral Immunity

Mediated by antibodies produced by B cells, effective against extracellular pathogens.

Cell-Mediated Immunity

Mediated by T cells, effective against intracellular pathogens and cancer cells.

Memory

A hallmark of specific immunity; memory T and B cells mount a faster and stronger response upon re-exposure to the same antigen.

Nonspecific Immune Response

Also known as innate immunity, the body's first line of defense against pathogens, providing immediate, broad protection.

Immediate Response

Nonspecific immune response that responds within minutes to hours.

Physical Barriers

Part of the nonspecific immune response; includes skin and mucous membranes that prevent pathogen entry.

Inflammatory Response

A localized reaction to infection or injury characterized by redness, swelling, heat, and pain.

Complement System

A group of proteins that enhances phagocytosis, inflammation, and pathogen lysis in the immune response.

Pattern Recognition Receptors (PRRs)

Receptors used by innate immune cells to recognize common pathogen-associated molecular patterns (PAMPs).

No Memory

Nonspecific immune response feature indicating it does not confer long-lasting immunity.

Broad Specificity

Characteristic of the nonspecific immune response that recognizes common patterns rather than specific antigens.
