Regulatory T cells Treg (picture above) is the existence of suppressor cells, which limit ongoing immune responses and prevent autoimmune disease, was postulated over 30 years ago. The recent phenotypic and functional characterization of these cells has led to a resurgence of interest in their therapeutic application in a number of immune-mediated diseases. Two broad subsets of CD3+CD4+ suppressive or Treg cells have been described: constitutive or naturally occurring versus adaptive or inducible Treg. (more…)

Some of the immediate sequelae of injury are uncomfortably familiar: Soon after an injury occurs, the affected site and its surrounding tissues become reddened, warm, swollen, and painful. These four signs which are probably the most useful and ubiquitous diagnostic clues in all of clinical medicine are hallmarks of acute inflammation, the body’s initial physiologic reaction to tissue distress. In its simplest form, inflammation is a response carried out by blood vessels and by the endothelial cells that line them. (more…)

The body’s innate resistance to many pathogens is provided by enzymes and other proteins in the blood and tissue fluids. These proteins are the effectors (ie, the active agents) of humoral innate immunity, and they have features in common with one another that are also characteristics of the innate immune system as a whole. First, these proteins are continually expressed throughout life, regardless of whether or not their protective effects are needed at a given moment. Second, although many of these proteins can be produced in higher quantities in times of need, their intrinsic properties (eg, substrate specificity and ige binding affinity) never change: The characteristics of these proteins have been shaped by evolution, are genetically determined, and are fixed at birth, so that they do not vary during an individual’s lifetime.

Primary immunodeficiencies occur with a frequency approaching that of cystic fibrosis (1:2500 live births). However, because they are perceived to be very rare and usually present with common infections, they are under-diagnosed. Often the diagnosis is not considered until substantial end-organ damage has occurred, by which time definitive treatment is only partially successful in preventing further infections. (more…)

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.

Allergens are the trigger for human body allergic reaction. It is one of human immunological process to react for invader substance. We find most allergens are common in our environment.

For daily life, of course we need our immune system. Without having immune system, we could not survive long, but there are times when the immune system may harm us rather than helps us.
