ReviewSex, the aging immune system, and chronic disease The aging process is associated with changes in the composition and function of the immune system and these changes may occur at an accelerated rate in men as compared to women. Moreover, after the age of menopause, the incidence of chronic inflammatory disease in women approaches or exceeds that observed in males.he mechanisms responsible for sex-specific differences in the immune response are complex and likely involve effects of the sex hormones on the immune system, genetic factors, and gender-specific behaviors and exposures.

Immune system Immunodeficiencies occur when one or more of the components of the immune system are inactive. The ability of the immune system to respond to pathogens is diminished in both the young and the elderly, with immune responses beginning to decline at around 50 years of age due to immunosenescence.

How Does Stress Affect the Immune System? The Connection with Immune System. The immune system is defined by the National Cancer Institute as a complex system of cells, organs and tissues that protect the body from bacteria, viruses and micro-organisms that try to invade it.Scientists and researchers have known for years that there is a connection between stress and the immune system. report in the November 1990 edition of Psychological Bulletin, states that stress suppresses immune system function and that, over time, the immune system does not adapt but instead continues to wear away. What was intended to protect the body, begins to harm it when unregulated.

- As a horse ages, its immune system tends to weaken in its response to a disease challenge. Trials have shown that older horses may develop a stronger immune response when they are vaccinated with a vaccine made from live influenza virus rather than a killed form of the same virus.ares can have antibodies to diseases they have had and also ones they have developed after being vaccinated against specific diseases. Researchers are now looking at other roles that may be played by the dam in the development of her foal's immune system.

- The immune system protects the body against illness and infection caused by bacteria, viruses, fungi or parasites. It is really a collection of reactions and responses that the body makes to damaged cells or infection.ancer can weaken the immune system by spreading into the bone marrow. The bone marrow makes blood cells that help to fight infection. Weakening of the immune system happens most often in leukaemia or lymphoma.

Believe it or not, your lungs are six weeks old - and your taste buds just ten days! So how old is the rest of your body? SKIN AGE: 2-4 WEEKS. The epidermis or surface layer of the skin is renewed every two to four weeks. This rapid turnover occurs because skin is the body's outer protection and is exposed to injury as well as pollution. Despite this constant renewal, we still get wrinkles as we get older.

- By middle age the thymus is much smaller, but it is still an important factor in the immune system. During the first few weeks of life, T-lymphocytes created in the thymus migrate to the blood stream and colonize lymph nodes through the body. These later begin to manufacture powerful antibodies vital for immunity.

The Aging Process Immunological Effects of Aging. The immune system is nothing short of a massive army at the ready, defending the body 24 hours a day. A sophisticated network of cells and organs stationed around the body protects you from invaders such as bacteria, viruses, fungi, and parasites.ging decreases immunity by impairing the body's production of antibodies. Fewer antibodies means a more sluggish immune system that's less responsive to foreign elements and to potential cancer cells.

Immune system The immune system is a system of many biological structures and processes within an organism that protects against disease. To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism's own healthy tissue.he ability of the immune system to respond to pathogens is diminished in both the young and the elderly, with immune responses beginning to decline at around 50 years of age due to immunosenescence. In developed countries, obesity, alcoholism, and drug use are common causes of poor immune function.

Immune system The immune system is involved in many aspects of physiological regulation in the body. The immune system interacts intimately with other systems, such as the endocrine and the nervous systems. The immune system also plays a crucial role in embryogenesis (development of the embryo), as well as in tissue repair and regeneration. Hormones. Hormones can act as immunomodulators, altering the sensitivity of the immune system. For example, female sex hormones are known immunostimulators of both adaptive and innate immune responses.

What is immune system depression? Immune & Lymphatic System Disorders. The lymphatic system is a key part of the immune system, draining excess fluid from bodily tissues and organs and disseminating white blood cells to fight infection. The white blood cells fight infection in the spleen and special vessels throughout the body called lymph nodes. If your immune system becomes compromised, the lymphatic system wont be able to work properly, causing swelling from a buildup of fluid in parts of the body.
