- The adaptive immune system is one of the two main immunity strategies found in vertebrates (the other being the innate immune system). Adaptive immunity creates immunological memory after an initial response to a specific pathogen, leads to an enhanced response to subsequent encounters with that pathogen.This process of acquired immunity is the basis of vaccination.Like the innate system, the adaptive system includes both humoral immunity components and cell-mediated immunity components. Unlike the innate immune system, the adaptive immune system is highly specific to a specific pathogen.he adaptive system response destroys invading pathogens and any toxic molecules they produce. Sometimes the adaptive system is unable to distinguish foreign molecules, the effects of this may be hayfever, asthma or any other allergies. Antigens are any substances that elicit the adaptive immune response.

Immunity (medical) 1 Artificially acquired passive immunity is a short-term immunization achieved by the transfer of antibodies, and can be administered in several forms.  Active immunity is long lasting immunity produced by the body's own immune system and involves the production of long lasting memory cells.

- Features of an Immune Response. An immune response is generally divided into innate and adaptive immunity. Innate immunity occurs immediately, when circulating innate cells recognize a problem. Adaptive immunity occurs later, as it relies on the coordination and expansion of specific adaptive immune cells.aving time is important to prevent a pathogen from establishing itself and infecting more cells in the body. An effective vaccine will optimally activate both the innate and adaptive response. An immunogen is used to activate the adaptive immune response so that specific memory cells are generated.

Immunity In Depth Adaptive immunity (also called acquired immunity), a second line of defense against pathogens, takes several days or weeks to fully develop. However, adaptive immunity is much more complex than innate immunity because it involves antigen-specific responses and immunologic memory. Exposure to a specific antigen on an invading pathogen stimulates production of immune cells that target the pathogen for destruction .

What is a Specific Immunity? Specific immunity is the body's learned immune response to disease-causing foreign substances, also referred to as pathogens or antigens. It is also commonly called acquired immunity or adaptive immunity.

- An effective vaccine will optimally activate both the innate and adaptive response. An immunogen is used to activate the adaptive immune response so that specific memory cells are generated.f a B or T cell is autoreactive, meaning its receptor recognizes antigens from the body's own cells, the cell will be deleted. Also, if a B or T cell does not receive signals from innate cells, it will not be optimally activated. Immune memory is a feature of the adaptive immune response.

- Innate Immunity. The ability of a multicellular organism to defend itself against invasion by pathogens (bacteria, fungi, viruses, etc.) depends on its ability to mount immune responses.

Introduction to Immunology Tutorial Adaptive immunity refers to antigen-specific immune response. The adaptive immune response is more complex than the innate. The antigen first must be processed and recognized. Once an antigen has been recognized, the adaptive immune system creates an army of immune cells specifically designed to attack that antigen.daptive immunity refers to antigen-specific immune response.

Adaptive Immunity The adaptive immune or specific immune response consists of antibody responses and cell-mediated responses, which are carried out by different lymphocyte cells, B cells and T cells, respectively.daptive Immunity Definition. Adaptive immunity is an important part of the immune system. It is protection from an infectious disease agent that is mediated by B-and T-lymphocytes following exposure to specific antigen, and characterized by immunological memory.

Immune system The adaptive immune response is antigen-specific and requires the recognition of specific non-self antigens during a process called antigen presentation. Antigen specificity allows for the generation of responses that are tailored to specific pathogens or pathogen-infected cells. cells and T cells are the major types of lymphocytes and are derived from hematopoietic stem cells in the bone marrow. B cells are involved in the humoral immune response, whereas T cells are involved in cell-mediated immune response.
