The Human Immune System and Infectious Disease Specific immunity is a complement to the function of phagocytes and other elements of the innate immune system. In contrast to innate immunity, specific immunity allows for a targeted response against a specific pathogen.Only vertebrates have specific immune responses. Two types of white blood cells called lymphocytes are vital to the specific immune response.Lymphocytes are produced in the bone marrow, and mature into one of several subtypes. The two most common are T cells and B cells. An antigen is a foreign material that triggers a response from T and B cells.on-Specific (Innate) Immunity. The human immune system has two levels of immunity: specific and non-specific immunity. Through non-specific immunity, also called innate immunity, the human body protects itself against foreign material that is perceived to be harmful.

- T and B lymphocytes, the mediators of adaptive immune responses, express antigen‐specific receptors that allow them to discriminate between self and a virtually unlimited number of nonself molecules. Their receptors specifically recognise and bind subdomains of foreign macromolecules which are called epitopes. T‐cell epitopes (TCEs) and B‐cell epitopes (BCEs) differ fundamentally in the way they are recognised by the immune system.

T Cells The “T cells” (so-called because they develop in a small organ called the thymus gland) are responsible for a variety of other immune responses. These responses include: 1  direct attacks on foreign substances such as bacteria, viruses, or foreign tissues; 2  augmenting the B cell response; and.

immune immune response. the specific response to substances interpreted by the body as not-self, the result being humoral and cellular immunity. The immune response depends on a functioning thymus and the conversion of stem cells to B and T lymphocytes.ypersensitivity is the result of an overreaction to substances entering the body. Examples of this kind of inappropriate immune response include hay fever, drug and food allergies, extrinsic asthma, serum sickness, and anaphylaxis.

Immune Response â Overview The immune system protects the body from invading disease-causing organisms, or pathogens. Pathogens and other non-self molecules are antigens  foreign molecules recognized by the immune system, stimulating an immune response. The majority of infections by pathogens occurs in mucous membranes of our body. cells must interact with Helper T cells, other specialized white blood cells, to initiate antibody production. An important concept is that once activated, memory cells are produced that insure that a more rapid and stronger immune response can be made upon re-exposure to the same pathogen.

Immune response Vaccination (immunization) is a way to trigger the immune response. Small doses of an antigen, such as dead or weakened live viruses, are given to activate immune system memory (activated B cells and sensitized T cells).ome of these directly attack foreign substances in the body, and others work together to help the immune system cells. Lymphocytes are white blood cells, which includes B cells and T cells. 1  B cells produce antibodies.

- The immune system and the inflammatory response. Many experts now see inflammation as arising from an immune system response that’s out of control. When you catch a cold or sprain your ankle, your immune system switches into gear. Infection or injury trigger a chain of events called the inflammatory cascade. The familiar signs of normal inflammation — heat, pain, redness, and swelling — are the first signals that your immune system is being called into action.

The Immune System: Information about Lymphocytes, Dendritic Cells, Macrophages, and White Blood Cells The Immune system is a complex network of cells (such as lymphocytes) and organs that work together to defend the body against foreign substances (antigens) such as bacteria, a virus or tumor cell.When the body discovers such a substance several kinds of cells go into action in what is called an immune response. macrophage is the first cell to recognize and engulf foreign substances (antigens). Macrophages break down these substances and present the smaller proteins to the T lymphocytes. (T cells are programmed to recognize, respond to and remember antigens).

Human Physiology/The Immune System This part of the immune system directly targets invading microbes. Our specific immune defenses respond to antigens. An antigen is a protein (or polysaccharide) molecule, typically on the cell membrane, that the body recognizes as nonself. They are found on microbes, foreign cells, or on cancer cells.

Immune response Antigens are substances (usually proteins) on the surface of cells, viruses, fungi, or bacteria. Nonliving substances such as toxins, chemicals, drugs, and foreign particles (such as a splinter) can also be antigens. The immune system recognizes and destroys, or tries to destroy, substances that contain antigens. Your body's cells have proteins that are antigens. These include a group of antigens called HLA antigens. Your immune system learns to see these antigens as normal and usually does not react against them.

Immune system The main response of the immune system to tumors is to destroy the abnormal cells using killer T cells, sometimes with the assistance of helper T cells. Tumor antigens are presented on MHC class I molecules in a similar way to viral antigens. This allows killer T cells to recognize the tumor cell as abnormal.he cells of the adaptive immune system are special types of leukocytes, called lymphocytes. B cells and T cells are the major types of lymphocytes and are derived from hematopoietic stem cells in the bone marrow.

How flu viruses beat the immune system Infection with viruses or bacteria triggers the immune system to release proteins called antibodies. The specific part of the virus or bacterium that triggers the antibody response is called an antigen. Once produced by the body (specifically, by the lymphoid tissue, which is part of the body's immune system), antibodies circulate in the bloodstream until they come into contact with an antigen.

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.oth innate and adaptive immunity depend on the ability of the immune system to distinguish between self and non-self molecules. In immunology, self molecules are those components of an organism's body that can be distinguished from foreign substances by the immune system.

How do specific immune responses lead to active immunity? exists and is an alternate of . A good example of specific immune response would be the actions the body takes when one gets a cold or flu virus. If one gets a flu virus the body will build up antibodies to that strain. It may not guarantee protection from another flu strain but rarely will one get any sicker if they catch the same strain again.

Vaccines Protect You Your immune system protects you from the disease by fighting off the invading germs. How does the immune system work? Your immune system is always on patrol in your body. When it comes across an invading germ, it attacks that germ. This is called an immune response. Here’s how an immune response works: Your immune system sounds the alarm so your body knows there’s an infection. It begins releasing antibodies to fight the germ — think of antibodies as soldiers designed to fight off the specific germ you have. This process can take a few days. The antibodies work to attack, weaken, and destroy the germ. Afterwards, your immune system remembers the germ.
