The acquired immune response is also known as the specific immune response. This involves the presentation of micro organisms antigens by macrophages to T and B lymphocytes (T and B cells). T cells and B cells specific to these antigens will then go through clonal expansion (mass production) to help carry out a specific response that has been 'acquired' as a direct result or particular microorganisms antigens.
T cells are divided into T helper and T killer, and B cells into memory cells and plasma cells.
T helper cells aid B cells in their production and carrying out their functions. T killer cells kill infected cells (those containing viruses or bacteria, as detected by their presentation of antigen on MHC Class 1 receptor molecules on their surface).
B cells differentiate into plasma cells and memory cells, plasma cells produce antibodies specific to the type or types of antigens detected. Memory cells have the ability to live for long amounts of time and quickly differentiate into plasma cells should the same antigens present at a later date, allowing a faster and more efficient immune response if infected again with the same microorganism.
The acquired immune response usually takes 7-10 days after initial presentation of the antigens by macrophages - unless this is a secondary response, in which case the person should have already produced memory cells so can deal with the invading microorganisms faster and more efficiently.
The innate (passive) immune system is responsible for initial responses, this is non specific and involves neutrophils largely.
The innate immune response is the body's first line of defense against pathogens and is non-specific, meaning it does not target specific pathogens. It includes physical barriers like skin and mucous membranes, as well as immune cells like macrophages and natural killer cells. The acquired immune response is more specialized and involves the activation of immune cells such as T and B lymphocytes that target specific pathogens based on memory from past exposures.
The innate immune response is the body's immediate, non-specific defense mechanism against infections. It is always ready to respond to invaders. The acquired immune response is specific to a particular pathogen and involves the production of antibodies and memory cells for long-term protection. It takes time to develop but provides a targeted defense against specific pathogens.
Lymphocytes
"AIDS" is the acronym for "Acquired Immune Deficiency Syndrome".
The acquired immune response helps provide long-lasting protection against specific pathogens through the activation of lymphocytes, including B cells and T cells. B cells produce antibodies that neutralize pathogens and mark them for destruction, while T cells help kill infected cells and coordinate the immune response. This tailored response not only clears infections but also establishes immunological memory, allowing for a quicker and more effective response upon re-exposure to the same pathogen.
Journal of Acquired Immune Deficiency Syndromes was created in 1988.
Active immunity can be acquired through natural exposure to an infectious agent, which triggers the body's immune response to produce antibodies. It can also be acquired through vaccination, where the immune system is exposed to a weakened or inactivated form of the pathogen, leading to the production of antibodies without causing illness.
Acquired immune deficiency syndrome or acquired immunodeficiency syndrome.
AIDs - Acquired Immune Deficiency Syndrome
Acquired Immune Deficiency Syndrome (AIDS) is caused by the Human Immunodeficiency Virus (HIV).
Naturally acquired active immunity is the type of resistance that is acquired from developing a disease. Naturally acquired active immunity leaves the person immune from developing the disease again in the future.
Looking for antigens is part of a specific immune response.
