Immune system cancer

Polysaccharides and generally carbohydrates represent the main carbon sink in the plant cell. Polysaccharides commonly serve nutritional (e.g., starch) and structural (e.g., cellulose) functions in plants. Some polysaccharides are cytotoxic against certain types of cancer, such as mouse skin cancer, or tumor lines in vitro (e.g., mouse Sarcoma-180). However, most polysaccharides exert their action through stimulation of the immune system (cancer immunotherapy). Plants containing polysaccharides with anticancer properties include the following ... [Pg.573]

Melatonin has side effects, but much less so than pharmaceutical sleeping pills. Long-term safety is not known. Prolonged use may have an influence on sex organs and reduce libido. It may slightly lower blood pressure. People with the symptoms of severe mental illness, severe allergies, autoimmune diseases, or immune system cancers such as leukemia should not... [Pg.150]

Know which drugs kill and which drugs maim (Fig. 7.3) Bactericidal antibiotics kill bacteria (cidal). Bacteriostatic agents only inhibit bacterial proliferation while the host s irmnune system does the killing Bactericidal agents are necessary for infections in patients with defective immune systems (cancer, AIDS, diabetes) and for overwhelming infections. Patients MUST take their full coarse of medication. Patient compliance is often poor because it appears that their infection has subsided when in fact it is only suppressed. [Pg.99]

DPP-IV is in a family of ubiquitous atypical serine proteases with numerous functions, including roles in nutrition, metabolism, the endocrine and immune systems, cancer growth, bone marrow mobilization, and cell adhesion [20]. The DPP-IV family includes four enzymes (DPP-IV, fibroblast activation protein (FAP),DPP8, andDPP9) and two nonenzymes (DPP-IV-like protein-6 DPP6, DPL-1, orDPP-X andDPP10 DPL-2) [20]. [Pg.181]

In any case, I eventually recovered (and so did Jerry), but my immune system must have suffered serious damage, which manifested itself three years later, when I collapsed in my office one day and was found to be bleeding internally from a form of rare stomach cancer, which necessitated major surgery but was fortunately localized. I again recovered and have had no further difficulties since. Whether weakening and knocking out my immune system to overcome the previous problems had any effect is not clear, but it could have been a factor. Despite my health problems I was able to continue my work without much interruption, and the scientific productivity of my group has not... [Pg.117]

Unfortunately, excess consumption of fatty foods has been correlated with serious human disease conditions. Effects on cardiovascular disease (95), cancer (96), and function of the immune system (97) have been shown. Numerous studies have been conducted to determine the effects of saturated, monounsaturated, and polyunsaturated fatty acids on semm cholesterol and more recently high density Hpoprotein (HDL) and low density Hpoprotein... [Pg.134]

The other global environmental problem, stratospheric ozone depletion, was less controversial and more imminent. The U.S. Senate Committee Report supporting the Clean Air Act Amendments of 1990 states, Destruction of the ozone layer is caused primarily by the release into the atmosphere of chlorofluorocarbons (CFCs) and similar manufactured substances—persistent chemicals that rise into the stratosphere where they catalyze the destruction of stratospheric ozone. A decrease in stratospheric ozone will allow more ultraviolet (UV) radiation to reach Earth, resulting in increased rates of disease in humans, including increased incidence of skin cancer, cataracts, and, potentially, suppression of the immune system. Increased UV radiation has also been shown to damage crops and marine resources."... [Pg.16]

Seveso, Italy, caused wide-spread pollution of the industrial site as well as its surroundings. Serious effects of dioxin were detected both in dontestic animals, such as cows and sheep, and in humans, the most serious early effects being a serious skin disease, chloracne, and alterations in the function of the immune system. Follow-up studies have demonstrated that this accident also increased the cancer risk in exposed individuals. ... [Pg.256]

Cancer now afflicts one out of four adults. One of the more promising therapies for certain kinds of cancers involves the use of interferon, a protein that occurs in minute quantities in the body where it is an essential part of the body s immune system. Interferon can be produced outside the body in cultures of transformed lymphoblastoid cells. A few years ago, it was possible to culture these human cells on scales up to a few hundred milliliters. Chemical engineers have now developed reactors for the aseptic culture of human cells on a scale 100,000 times larger, making it possible to produce human interferon in practical useful quantities. [Pg.42]

Globally, undernutrition is widespread, leading to impaired growth, defective immune systems, and reduced work capacity. By contrast, in developed countries, there is often excessive food consumption (especially of fat), leading to obesity and to the development of cardiovascular disease and some forms of cancer. Deficiencies of vitamin A, iron, and iodine pose major health concerns in many countries, and deficiencies of other vitamins and minerals are a major cause of iU health. In developed countries, nutrient deficiency is rare, though there are vulnerable sections of the population at risk. Intakes of minerals and vitamins that are adequate to prevent deficiency may be inadequate to promote optimum health and longevity. [Pg.474]

It is suggested that altered cells which could be potentially malignant are recognized by the immune system and eliminated. This must mean that cancer cells possess new antigens on their cell surface. These antigens have been identified and can be categorized into three groups. [Pg.301]

Health benefits — Research reports indicate that natural (3-carotene possesses numerous benefits for the human body and consistently supports the use of (3-carotene as part of the human diet. The human body converts (3-carotene to vitamin A via body tissues as opposed to the liver, hence avoiding a build-up of toxins in the liver. Vitamin A is essential for the human body in that it assists the immune system and helps battle eye diseases such as cataracts and night blindness, various skin ailments such as acne, signs of aging, and various forms of cancer. [Pg.404]

The acquired immune deficiency syndrome (AIDS) was first recognized in 1981, and described in a cohort of young homosexual men with significant immune deficiency. Since then, human immunodeficiency virus type 1 (HIV-1) has been clearly identified as the major cause of AIDS.1 HIV-2 is much less prevalent than HIV-1, but also causes AIDS. HIV primarily targets CD4+ lymphocytes, which are critical to proper immune system function. If left untreated, patients experience a prolonged asymptomatic period followed by rapid, progressive immunodeficiency. Therefore, most complications experienced by patients with AIDS involve opportunistic infections and cancers. [Pg.1253]

The cell surface contains antigens, which are referred to as CD, which stands for cluster of differentiation. The antibodies are produced against a specific antigen. When administered, usually by an intravenous injection, the antibody binds to the antigen, which may trigger the immune system to result in cell death through complement-mediated cellular toxicity, or the antigen-antibody cell complex may be internalized to the cancer cell, which results in cell death. Monoclonal antibodies also may carry radioactivity, sometimes referred to as hot antibodies, and may be referred to as radioimmunotherapy, so the radioactivity is delivered to the cancer cell. Antibodies that contain no radioactivity are referred to as cold antibodies. [Pg.1294]

There is clear evidence linking defects of the immune system to the development of NMSC. For example, it is observed that patients receiving chronic immunosuppressant therapy for organ transplantation have a 50% risk of developing SCC within 20 years of transplantation, and 30% of these cancers are highly aggressive.21 Additionally, patients with human immunodeficiency virus (HIV) infection are predisposed to melanoma.18 Data also support the idea that UV radiation... [Pg.1429]

Bladder tumor-associated antigen (BTA), a human complement factor H, is produced by bladder cancer cells (men two to three times as often as women). Cancer cells are sometimes seen in urine samples by microscope cytoscopy (examination of the bladder with an instrument inserted into the urethra), which can reveal abnormal areas. Biopsy is needed to confirm the diagnosis. Early stage cancer confined to the bladder wall can often be removed with a cytoscope. If several tumors are present, they are removed by infusing the bladder with a solution containing bacteria able to stimulate the immune system. [Pg.196]
