Allergen-Specific Immunotherapy Mechanisms & The Involvement Of Treg Cells

allergen specific immunotherapy
Allergen-specific immunotherapy is highly effective in the treatment of IgE-mediated allergy diseases such as rhinitis, conjunctivitis, asthma, and venom allergy hypersensitivity. It is the only treatment that leads to lifelong tolerance against previously disease-causing allergens due to restoration of the normal immunity. (more…)

Bacterial Lipopolysaccharide and Humoral Factors Immune Systems

bacterial lipopolysaccharide
One especially favored target for immune recognition is bacterial lipopolysaccharide (LPS). This macromolecule is found only in the outer lipid bilayer that surrounds the cell walls of gram-negative bacteria, such as Neisseria, Salmonella, and Escherichia coli. Each molecule of bacterial lipopolysaccharide consists of a core carbohydrate linked on one side to a phospholipid (called lipid A) that is anchored in the bilayer and on the other side to a long polysaccharide chain (called the O sidechain) that extends outward from the bacterial surface (Figure 1 bellow). The sequence of sugars making up the O sidechain is species-specific and highly variable, even within a single bacterial genus: For example, more than 1000 variants in Salmonella are known. (more…)

Allergen-Specific IgE and Serum IgE: Early Immune Development Underlying Allergies

Serum IgE
A paradigm of immune development underlies allergy development and progression in early childhood. Briefly, the immune system of the fetus is maintained in a tolerogenic state, preventing adverse immune responses and rejection between the mother and fetus. Placental interleukin-10 (IL-10) suppresses the production of immune-potentiating inter-feron gamma (IFN-y) by fetal immune cells. IFN-y downregulates the production of pro-allergic cytokines, such as IL-4 and IL-13. (more…)

Allergen Avoidance and Environment Control: Management of Allergy & Asthma

Allergen Avoidance
Asthma and allergic diseases are common in both children and adults. Their development depends on an interaction between asthma genetic and asthma environmental risk factors. Genetic manipulation in multi factorial diseases such as asthma is not feasible in the foreseeable future. However, theoretically, environmental exposures can be controlled in an attempt to stem the rising prevalence of these diseases (primary prevention). Environmental exposures may also influence the frequency of symptoms and the requirement for medication in those with established disease. (more…)

Cow’s Milk Allergy: IgE-Mediated Allergy or Lactose Intolerance?

cow milk allergy

Cow’s milk allergy results when antibodies against milk allergens are produced by the immune system.

Milk allergens are proteins; more than 25 distinct milk proteins have been identified in the various fractions of milk. The fractions include casein, whey, serum, and certain additional ingredients. (more…)

Feeding Lactose-Intolerant Baby: How to Give Milk-Free Infant Formulas

lactose intolerant baby

If the breast-fed baby is lactose intolerant (usually a temporary condition following intestinal infection at this age), mothers can continue to breast-feed, or pump their milk and treat it with lactase enzyme, until the baby’s symptoms stop. Details concerning feeding the lactose-intolerant infant are provided. There is no point in mothers’ eliminating milk and milk products from their diet to treat lactose intolerance in the baby, because their breast milk will contain 6 percent lactose (w/v) regardless of whether or not they consume cow’s milk. (more…)

Characteristics Of Children Diagnosed With Food Allergies

children food allergies
A cross-sectional, descriptive, questionnaire-based survey was conducted in schools in Toulouse, France, to determine the prevalence of food allergies among children in school. The first goal of the survey was to estimate the prevalence of food allergies. The second goal was to determine the main characteristics of the allergies. The questionnaires (3500) were distributed in 150 classes in eight schools. The return rate was 77.6% (2716). (more…)

Allergies and Age - When Likely Allergy to Occur the First Time

Allergies can be defined as inappropriate immune system reactions to a foreign substance entering body. Allergies are kind of diseases of immune system works to react to certain substances called allergens. Normally when a person is exposed to a harmless substance such as pollen, causes the body natural immune system to respond as if the substance is harmful. Some allergies are inherited from their parents or can be gained in environmental exposure. There are several common allergen exposures like mold, animal dander, pollen, dust mites, and many others. (more…)

Gastrointestinal Allergy Symptoms and Food Intolerance

gastrointestinal allergy symptoms
Gastrointestinal allergy can be classified according to the triggering antigen, the mechanism of immune reaction, or the anatomic site of reaction.

Gastrointestinal allergy may be triggered by food components (e.g. food proteins or glycoproteins), and by other antigen antibody reaction to (e.g. bacterial disease, viral, fungal, and worm antigen), drugs and chemicals, (more…)

Seasonal Allergic Rhinitis Symptoms: Testing and Treatment

seasonal allergic rhinitis
Seasonal allergic rhinitis is stimulated by an allergic reaction of human body to pollen and spores. This is much depending on the season and region as they are carried by the wind. Your doctor may recommend you to undergo allergies medication that depends on your type of allergy rhinitis. (more…)
