-1 gene which is believed to play a major role. Women of child bearing age‚ who are on oral contraceptive pill or Hormone Replacement Therapy‚ are at an increased risk of developing SLE (1.2-2 folds). Estradiol binds to receptors located on T&B lymphocytes and increases their activity and survival favoring prolonged immune response. Due to this females of many mammalian species generate higher antibody response compared to males. Individuals with Klinefelter Syndrome (XXY) have a

IGCSE Biology Notes Refined by KmQ Unit 1 : Characteristics of living things Biology is the study of living organisms. For something to be alive it needs to perform all seven functions of living things.MRS GREN Movement‚ Respiration‚ Sensitivity‚ Growth‚ Reproduction‚ Excretion‚ Nutrition. 1. Movement Most organisms are able to move their whole body even plants can shift their stem towards the sunlight and their roots move towards healthy soil. 2. Respiration IT is the breakdown of food

only infects the infant near or at the time of birth. The virus dies quickly without a host. AIDS (Acquired ImmunoDifficiency Syndrome) weakens the body¹s immune system so it is sensitive to infection. The AIDS virus primarily attacks the T lymphocytes‚ which are a main part of the immune system. The virus is also incubated in cells called macrophages‚ where it is accidentally sent to other‚ healthy cells in the body like neurons and lymphatic cells. After HIV is contracted‚ the person looks

Asthma and emphysema are both known as obstructive lung diseases. Obstructive lung disease occurs when the airway is obstructed and is worse with expiration. For example‚ more force is required to exhale and emptying the lungs is slowed (Huether & McCance‚ 2012‚ p. 689). The most common type of obstructive lung diseases are asthma‚ chronic bronchitis‚ and emphysema. Although‚ they are categorized as obstructive lung disease they have many similarities in that they have similar symptoms such as

entering the body through a mosquito bite‚ the virus reaches the central nervous system (CNS) via leukocytes where JEV virions bind to the endothelial surface of CNS and are internalised by endocytosis. But still it’s not clear that macrophages and B lymphocytes can also harbour JEV. In other infections flavivirus like West Nile virus (WNV)‚ macrophages could serve as a reservoir‚ spreading

is it a cure. Transfer Factors molecules are completely unique. They contain information that can be transferred from one immune system to another. What it does is it educates‚ enhances‚ and balances the immune system by way of focusing on the T-Lymphocytes‚ or Killer T-Cells. This induces a cell-mediated immune response‚ which causes a positive domino effect on the entire human body Transfer Factors are one of nature’s most elegant form of immune communication. It is also responsible for keeping
