Acquired immune deficiency syndrome‚ or AIDS‚ is a recently recognized disease. It is caused by infection with the human immunodeficiency virus (HIV)‚ which attacks selected cells in the IMMUNE SYSTEM and produces defects in function. These defects may not be apparent for years. They lead‚ however‚ to a severe suppression of the immune system ’s ability to resist harmful organisms. This leaves the body open to invasion by various infections‚ which are therefore called opportunistic diseases‚ and

There has been extensive research into the link between stress and the immune system that shows that the link is indeed very strong with a positive correlation. The research is seen in the general adaptation syndrome‚ Stone’s experiment on stressful events and the links to symptoms‚ Cohen et al experiment on the common cold‚ and Keicolt Glaser who looked into immune function. Stress has been found to suppress the immune system allowing people to contract disease far faster than a person with less

The effects of catecholamines on the immune system in particularly the effects they have on T-helper lymphocytes The immune system is a vast and versatile collection of cells within the human body. These cells prevent the spread of infections‚ viruses and bacteria throughout the entire body and help in maintaining a healthy lifestyle. The immune system can be affected in many ways with a variety of substances up or down regulating its ability to function correctly. Catecholamines which are found

Medicine and Disease Study Questions 1-10 1. Describe the role of the macrophage in the immune response. They are known as the vulture cells randomly engulf and destroy bacteria‚ cell debris or foreign matter. 2. State the origin and purpose of lymphocytes. The immune cells‚ or lymphocytes as well as macrophages provide the specific mechanism for the identification and removal of foreign material. Natural killer cells are lymphocytes distinct from the T and B lymphocytes. They destroy

Outline and evaluate research into relationship between the immune system and stress-related illness. The immune system is a collection of billions of cells that travel through the bloodstream. They move in and out of tissues and organs defending the body against foreign bodies (antigens). There are two types of lymphocytes… B cells… these produce antibodies which are released into the fluid surrounding the body’s cells to destroy the invading viruses and bacteria. T cells… if the invader gets

from pathogens. The innate immune response is the first line of defense against these pathogens. Pattern associated molecular factors (PAMPs) are viral factors including proteins‚ lipids‚ and viral nucleic acids that are recognized by pattern recognition receptors (PRRs) within the cell. During viral infection‚ PAMPs accumulate in different cellular components and once recognized by the PRRs activate the intracellular signaling pathways that are involved in the innate immune response. These pathways

AIDS: Acquired Immune Deficiency Syndrome I am doing a report on AIDS‚ I don’t know much about AIDS but I will tell you what I know. I know that it is transmitted by sexual contact‚blood‚needles‚children during/before birth. I also know it affects the immune system directly‚ It is caused by the virus HIV which they have no cure for either AIDS or HIV at the current moment‚ but they are doing serious research on them. I call it the "Generation X Disease" because it mostly affects my sex- oriented

in order to understand how an individual’s immunological phenotype is the result of its genotype‚ the environment‚ and development. For the first experiment‚ Dr. Brown’s research was testing how selection on basal and maximal metabolic rates affect immune function. In addition‚ Dr. Brown had four hypotheses for this particular experiment‚ two were for basal metabolic rate and two were for maximal metabolic rate. Moreover‚ trade-off with BMR decreases as basal metabolic rate increases‚ and assimilation

composed of complicated and intricate systems that work together to keep us alive and able to move and process the things we find to be simple such as breathing or blinking. There are 11 systems in our body‚ each in charge of something different and supplying support to the other. Those 11 systems are the‚ nervous‚ skeletal‚ muscular‚ circulatory‚ respiratory‚ digestive‚ endocrine‚ reproductive‚ excretory‚ integumentary and immune systems.
