Immune Cell Function (Overview)

Immune cells are the white blood cells (WBC) in the blood. There are different types of wbcs that fight infections or respond to immunizations in different ways. . For example, your immune response to the 1st measles vaccine differes from the second vaccination in the types of immune cells that react to the vaccines. Immune cells also go out of whack, and this causes autimmune disease.

I am Taking Mirtazapine 15mg is it true to say it can reduce your white blood cells and immune function so you are more susceptible to infections ?

I am Taking Mirtazapine 15mg is it true to say it can reduce your white blood cells and immune function so you are more susceptible to infections ?

Not typically: Remeron (mirtazapine) causing leukopenia is not a common occurrence and if occurring should stop. Periodically blood counts are checked. If there is a drop the medication is stopped. This is one of many medications can do this. Low counts over time can make you more susceptible to infecions but usually as part of another process. ...Read more

When testing the immune system can bloods test. B cells t cells nk killer cells, what is the best way to test immune function in depth?

When testing the immune system can bloods test. B cells t cells nk killer cells, what is the best way to test immune function in depth?

Good start: Yes, the parameters you mentioned can be tested easily, and there are numerous other tests which may help to assess "immune function" which can be utilized depending upon the clinical situation and indices of suspicion. You might see either an infectious diseases expert or an immunologist. Good luck. ...Read more

Hiv neg- immune labs ok "good humoral and T cell function" except- Cd4=527, Range 533-1674. Cd3=717, Range 958-2388. Doc says low. Is it severely low?

Hiv neg- immune labs ok "good humoral and T cell function" except- Cd4=527, Range 533-1674. Cd3=717, Range 958-2388. Doc says low. Is it severely low?

No: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, your counts are not severely low and may be your normal. Why was the test done? For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more

Can you tell me how I could explain the steps in the cell-mediated immune response?

Can you tell me how I could explain the steps in the cell-mediated immune response?

That is a long story: The concepts of cell mediated vs antibody mediated immunity developed to explain different reactions. The body uses cell mediated immune mechanisms to fight infections where the infecting agent gets inside the cells. In tuberculosis we use that to help diagnose previous exposure. The TB skin test looks for cells to fight the parts of the TB bacterium that is injected in the skin. (cont.in comment) ...Read more

Immune system: The immune response occurring on second and subsequent exposures to an antigen, with a stronger response to a lesser amount of antigen, and a shorter lag time compared to the primary immune response. ...Read more

If the immune system targeted specific nerves cells why would the body not be able to feel the process of those nerves cells being attacked?

If the immune system targeted specific nerves cells why would the body not be able to feel the process of those nerves cells being attacked?

No sensory nerves...: If there are no sensory nerve endings in that part of the body, then no sensations are detected, so thus the brain receives no information (and so we don't "feel" anything going on). Imagine a city with 1000 security cameras. There will be "blind spots" in places that the cameras aren't looking. The police do not see things that are happening in the "blind spots". ...Read more

Does an auto immune disorder have anything to do with a defect in killer t cells?

Does an auto immune disorder have anything to do with a defect in killer t cells?

Maybe, maybe not: There are many different types of autoimmune disorders, many of which are not associated with immune deficiencies. Certain immune deficiencies (e.g., wiskott-aldrich syndrome, cvid, apeced) can be associated with autoimmunity, but only some are associated with defects in "killer" t cells. Some disorders of immune regulation (e.g. Hlh) can act like autoimmunity. See an immunologist for more info. ...Read more

What makes immune cells only attack one type of antigen, as opposed to multiple different antigens?

What makes immune cells only attack one type of antigen, as opposed to multiple different antigens?

It's complicated: When immune cells come into contact with a foreign substance (called an antigen), they engulf that substance and either start making antibodies to it or activate other immune cells to come into the area to fight off the foreign invader. Antigens are fairly specific so antibodies that form are also fairly specific. Sometimes mistakes occur however. Here's a link to more: http://bit.ly/1uy9lyG ...Read more

Could the immune system attack nerve cells and kill the nerves throughout the body? Is this rare? Whats this diagnosed as.

Could the immune system attack nerve cells and kill the nerves throughout the body? Is this rare? Whats this diagnosed as.

Nerve cells: Yes, the nervous system can be the target of an inflammatory response by the immune system. If such attack occurs in the brain or spinal cord it is called cerebritis or gliosis and myelitis. Multiple sclerosis is an example of this phenomenon. If the attack occurs in the nerves of te arms or legs then it is called neuropathy. Certain clinical syndromes are recognized depending the progression and distribution. ...Read more

If neurons are dramatically damaged by immune cells and stop or produce very little electrical and chemical signals what's this diagnosed as ?

Far too broad: What you have implied is some form of immune or autoimmune neuronopathy; however, the differential diagnosis of this is very broad. See neurologist. Look for hard data regarding what parts of the nervous system are being affected and what blood studies show about state of inflammatory mechanisms. What evidence are you using for "dramatically damaged"? ...Read more

Is there a way to measure your immune system specifically natural killer cells?
