What makes food particles antigens in the human body?

What makes food particles antigens in the human body?

Food antigens: Antigens are substances, typically proteins, that are recognized by the immune system as foreign to the body. Typically, protective antibodies (igg, IgM or iga) are made to foreign proteins however, some times allergic antibodies (ige) are created. Not all persons have the genetic predisposition to make ige but about 1/3rd of the population is prone to this problem. ...Read more

Antigen (Definition)

Antigens are chemicals which upon exposure to the surface or inside of the body, will cause a reaction term allergic. Many substances will do this and allergic response is the basis for immunological protection for ...Read more

What happens in the body after the microbes that produce food borne illness are swallowed?

What happens in the body after the microbes that produce food borne illness are swallowed?

Three choices.: Three choices. First, the immune system generates a significant enouch immune response to kill them with their chemicals. If insufficient they can learn to live with us as a parasite feeding off of us. Or third they can actively go on to cause active invasion of tissues and organs. ...Read more

Does the human body naturally produce small LDL particles? Why or what are the functions of small LDL cholesterols in the human body?

Does the human body naturally produce small LDL particles? Why or what are the functions of small LDL cholesterols in the human body?

LDL function.: LDL cholesterol does have a function in our bodies, so in some respects is necessary. The small dense LDL particles to which you refer, however, are more atherogenic than the other large buoyant LDL particles. Niacin supplementation can improve your LDL subtype, changing small dense LDL to large buoyant LDL. ...Read more

In what ways are antibodies released in the human immune response?

In what ways are antibodies released in the human immune response?

Antibodies: Antibodies are produced by b lymphocytes. There are five antibodies. Infection stimulates b cells as well as other cells to trigger antibody production. ...Read more

How does the body filter toxins (ie heavy metals) from the environment and in the food that we eat?

How does the body filter toxins (ie heavy metals) from the environment and in the food that we eat?

Via the kidneys: Through the glomerular filtrate. Even the ones that are a bit toxic to the kidney, like cadmium, make it out. There's some storage of some of the problem ones in the bones. Please be discerning in your reading, and be advised that most "independent" labs that will test you for multiple heavy metal poisonings are cynical scams. ...Read more

The polio vaccine injects antigens from the poliovirus into our bodies. Why doesn't that make us sick?

The polio vaccine injects antigens from the poliovirus into our bodies. Why doesn't that make us sick?

Dead=dead: It takes live virus invading your body to make you sick. Injecting non-living antigens just allow your body to build antibodies to those antigens. If exposed to the living virus (that has those antigens)in the future, the antibodies would kill them before they make you sick.That is how most vaccines work. ...Read more

What is the mechanism that the body uses to create fat cells in adults? And how does the body choose where to produce/store fat?

Physiology: You are asking us a question that would take a whole textbook to answer. This forum is not designed to teach you science or provide you with a whole textbook lesson on physiology. We are happy to answer specific question about specific symptoms or problems. But you are asking something that we cannot answer specifically in only 400 characters. ...Read more

Is e.Coli a food-borne disease that gets in the body and produces toxins as they grow in your body?

Is e.Coli a food-borne disease that gets in the body and produces toxins as they grow in your body?

No, from gut.: E. Coli is an enteric bacteria, that is, it is found in your gut. It is also in the gut of many animals, so when meat is processed, it likely gets introduced through fecal contamination. Especially bad are the enteroinvasive kinds, like e. Coli o157:h7, that produce a dysentery syndrome, bacteremia, and sepsis. Often this is in contaminated meat, and uncooked meat, so cook meat thoroughly. ...Read more

The human immunodeficiency virus (hiv) infects helper t cells. What is the role of these cells?

The human immunodeficiency virus (hiv) infects helper t cells. What is the role of these cells?

Cellular immunity: These are cells that work as part of the cellular immune system, fighting certain fungal (e.g. Cryptococcus), viral (e.g. Herpesviruses), parastic (e.g. Toxoplasma), and bacterial (e.g. Tuberulosis) infections. The cellular immune system also helps to prevent certain cancers, such as lymphomas. ...Read more

Which part of the human body cannot get cancer?

Cells without nuclei: Any organ containing cells with nuclei and DNA can be subject to developing cancer. In certain tissue like the teeth or hair where no nuclei are present and DNA mutations are not found then malignancies should not appear. ...Read more

What are the symptom in the body when excess protein is stored in the body?

Can't store protein: Unlike carbohydrates and fat, there is no storage form in the body for proteins. Proteins are either incorporated into tissues or they are eliminated. However there are conditions in the body such as amyloidosis which involve abnormal deposition of misfolded proteins; these can cause a variety of problems including heart failure and kidney failure. ...Read more

Can you tell me process of digestion of food in small intestine in human beings ?

Can you tell me process of digestion of food in small intestine in human beings ?

Not in400 characters: There are entire text books written about this topic, some of which are thousands of pages in length. Essentially, the body mechanically breaks food down, then uses chemical reactions and enzymes to absorb the nutrients, and then excretes the waste products in the stool. The detail involves how it does that with each different type of nutrient. Fascinating field! ...Read more

Why does our body not reject the insulin made from genetically modified organisms like bacteria?

Why does our body not reject the insulin made from genetically modified organisms like bacteria?

Similar structure: Hi the engineered insulins are VERY similar in structure to native human insulin. The human insulin gene is rearranged so that the engineered protein differs from regular human insulin by only 1 amino acid. The change is significant for how the insulin molecules behave at acid/neutral pH or how they fail to aggregate, but not enough to be recognized as different by the immune system. Fortuitous! ...Read more

What are the chemical stimuli in the human body the eyes fingers etc (sense organs) or something else ?

What are the chemical stimuli in the human body the eyes fingers etc (sense organs) or something else ?

Neurochemicals: All sensory organs convert a stimulus (light, sound, heat, cold, touch, pressure, etc.) into an electrical signal which travels up the nerve for the body to respond to that stimulus. There are a variety of neurochemicals that are part of this relay including acetylcholine and epinephrine and many others. The specific one depends upon the circuit in question. ...Read more

Why is it that the human body does not reject bovine or pig heart valves. Can cells from different animals survive in humans?

Medical technology: The valves are derived from pig or bovine but are treated in a laboratory to remove the antigens that would cause a reaction against them in a human body. Medical technology is amazing! ...Read more

Which type of food unleashes leptin in the body?

Oral glutamine: Digestive tract cannot absorb leptin, so even if you could find a food rich in leptin it wouldn't help - forget about finding foods rich in leptin. The body has to create it's own leptin. You want is for your body to respond to leptin more efficiently (ultimately resulting in lower leptin levels!). As you lose weight, leptin levels drop, because fat itself causes the body to produce more leptin. ...Read more
