There are thousands of components to the immune system, and during the course of learning about some of these it can appear that the immune system is far more complex and complicated than necessary for achieving what is, on the surface, the simple task of eliminating an infectious organism. There are a number of reasons why the immune system is complex. The first of these is the desirability of eliminating pathogens without causing damage to the host. Getting rid of a pathogen is theoretically easy. If you had an infection in your liver you could produce a nasty toxin that would kill the pathogen; unfortunately it would also destroy your liver. Killing pathogens is not difficult, but getting rid of pathogens without damaging the host is much more complicated. (more…)

The immune system consists of proteins, cells and organs that are concerned with defense of the individual, primarily against the threat of disease caused by infectious organisms. An infectious organism that causes disease is called a pathogen and the individual (person or animal) that is infected by a pathogen is called the host. Not all infectious organisms cause disease and some are actually beneficial, for example bacteria living in the gut help to digest certain foods. Infectious organisms that help the host are called commensalism organisms. (more…)

Local micro environmental factors are crucial in determining both susceptibility to vascular remodeling and the extent of angiogenesis. Major exogenous triggers of airway inflammation in asthma include viruses and inhaled aeroallergens, both of which are known to be associated with the production of angiogenic factors . These stimuli elicit reciprocal immune responses, through elaboration of Th1 and Th2 cytokines. (more…)

The precise mechanisms underlying the effects of Specific Immunotherapy are not well understood but several studies have shown that Specific Immunotherapy T inhibits both early and late immune responses to allergen exposure.
Recently, there have been many studies aimed at elucidating the mechanisms by which allergen-specific immunotherapy works. (more…)
