3. Describe the effect of an incompatibility between mother and fetus in Rh blood type. 4. What are antigens and antibodies? How do they interact to cause a transfusion reaction? * An antigen is a molecule that sometimes stimulates an immune response. An antibody is a blood protein produced in response to and counteracting a specific antigen. Antigens are what causes a person to need a transfusion because their body is resisting their own blood. Antibodies are what accept the new blood

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

Outline and Evaluate research into the relationship between the immunes system and stress-related illness. Stress has been widely identified to be linked with illness‚ which has therefore attracted researchers to investigate the relationship between the immune system and stress. Cohen et al for instance conducted a study where 369 participants were asked to complete a questionnaire which measured their Psychological Stress Index‚ consisting of a scale measuring their own perception of their stress

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
