Allergies Research Papers

Allergies affect many children, particularly food allergies; this in turn can lead to social problems as they may become excluded from certain situations where their allergies are not known. In contrast they may feel a certain social stigma as their allergies are

Almost everyone has an allergy, whether or not they are massive, like peanut allergies, or minor, like seasonal allergies. The first time I had allergy was in my Ninth grade year of High School. When Miss. Town son's writing class came along and acted like a cup of milk in my existence.

The ironic thing about allergens is that most aren’t harmful to the body, but this doesn’t stop the immune system for mistaking them for foreign bodies, which is why it decides to fight back. Our immune systems are amazing things. They create proteins to fight disease, which are known as antibodies. These antibodies try to battle it out against the antigens. Once our immune system creates certain antibodies, they’ll recognize the same intruders again and protect our bodies automatically year in year

Allergy induced asthma can be caused by allergies that range from pollen and pet dander to roaches

Seasonal nasal allergies (hay fever) are caused by pollen allergens that come from grasses, trees, and weeds. Year-round nasal allergies (perennial allergic rhinitis) are caused by allergens such as house dust mites, pet dander, and mold spores.

Allergies are very common and global chronic diseases which occurs when the people’s immune system overreacts a substance which is judged to be harmful to human body. It’s now becoming major public health problem in developed countries especially in Australia. In 2007, according to an ASCIA-Access Economics Report that 4.1 million Australians (19.6% of the population) had at least one allergic disease. Also specialists speculate if Australia’s ageing trend continues, there will be a 70% increase in the number of Australians with allergy, from 4.1 million in 2007 to 7.68 million by 2050 (26.1% of the population). In this article, three aspects which related to allergies in Australia will be discussed in turn: causes, symptoms

Allergy skin testing is done to check whether you have an allergy to something. An allergy occurs when your body's defense system (immune system) is more sensitive to certain substances. The immune system overreacts to the substance, causing allergy symptoms. Allergy skin testing can be used to help find out which substance may be causing your symptoms.

Allergic rhinitis is started by an allergic immune response to inhaled allergens. Atopic people have a genetic predisposition to become sensitised to harmless allergens. Dendritic cells which act as antigen-presenting cells capture the allergen and present allergenic peptide to T lymphocytes in lymph nodes. CD4+ T cells play an important role in starting and orchestration of the allergic immune response by secretion of cytokines such as interleukins 4, 5, 10, and 13. Interleukin 4 is fundamental cytokine in driving sensitisation to allergens. Interleukin 4 stimulatesthe IgE switch in B lymphocytes. After releasing of IgE into the bloodstream it binds to receptors on the surface of mast cells and basophils. When the patient exposure to the allergen and the allergen reach nasal mucosa of sensitised individuals, they bind allergen-specific IgE on the surface of mast cells, resulting in release of inflammatory mediators such as histamine.

If you are like many people, you might suffer from fall allergies as the temperatures start to cool down. Although you might enjoy the cooler temperatures and the pretty colors of fall, you might not enjoy the discomforts of your allergies.

Childhood allergy is an exaggerated reaction by the immune system in response to certain foreign substances. These foreign objects may not be really harmful thus it is called an exaggerated response. In an attempt to protect the body, the immune system produce antibodies called immunoglobulin that causes the mast cells and allergy cells to release chemicals, including histamine resulting in allergic reactions. In most people, allergies appear during infancy and childhood. Some allergies can be outgrown while some lasts for a lifetime. It is best to consult an allergy specialist so that the source can be easily avoided and the symptoms treated. When avoidance measures fail or impossible,

Allergy has been defined as the result of immune reaction to antigens known as allergenes. In the last decades it has been accepted that there is a genetic basis to susceptibility to most common diseases, including allergies. Individual susceptibility and environmental factors play the most important roles. Atopy represents

Have you ever asked yourself what is the main factor behind all of those irritating allergies? At some point in every person’s life they experience some type of allergy that can range from dust, animals, pollens, food, etc. Some of the symptoms that come along with those allergies can range from a painless skin rash to life-threatening reactions causing ones airway to be obstructed. Some people have suggested that if you are exposed to certain foods or bacteria’s you may develop some type of reaction later in life. Studies show that every 7 years our body’s allergies change causing us to either develop new allergies or some vanish into thin air like they were never there. We are going to get to the bottom of this issue so the real question you should be asking yourself is “Are Genetics responsible for allergies like everyone assumes or is there an underlining cause that we may just not have an answer to what causes them?” In order to prove this theory to be wrong or right research has been conducted on identical and fraternal twins. If both twins contract the same allergy then theories may be right stating that allergies are affected by genetics.

Pollen allergies are one of the most common allergy that someone would hear about. This allergy occurs when there are multiple antigens in the air that get breathed in and then triggers one’s immune system to overreact and cause a reaction. Symptoms of a pollen allergy include sneezing, running nose, watery eyes, cough, and wheezing. This allergy can also aggravate asthma symptoms and make one’s asthma worse. Allergies are an excessive reaction from your body’s immune system that while eliminating the allergens in the pollen or whatever antigen, overestimates the threat and creates this greater than necessary

Anaphylaxis is the medical term for a serious allergic reaction that can start very rapidly and result in death. In the first phase of a severe reaction the immune system has an over reactive response. The immune system can release an excessive amount of histamines into the body as a reaction to an allergen. The overabundance of chemicals can cause the body to go in shock. A second reaction, the biphasic reaction, can happen as long as 12 hours after the first reaction.

Allergies are among the most common inveterate case worldwide. Allergy symptoms range from making you powerless to putting you at risk for life-menacing reaction.Food allergies are defined as “ the body 's abnormal responses to harmless foods; the reactions are caused by the immune system 'sreaction to some food proteins” (thefreedictionary.difntion.com).In other words,The job of the body’s immune system is to identify and ruin germs (such as bacteria or viruses) that make you sick. A food allergy results when the immune system wrong targets a harmless food protein an allergen as menace and attacks it.
