How do white blood cells recognize particular types of pathogen?

Lymphocytes make a different antibody for each pathogens. They have this 'memory' of a pathogen they had previously come in contact with. The person is then said to be immune to that disease, as the lymphocytes know immediately which antibody to make.

Hope that this helps!!! :-)

∙ 12y agoa t-cell recognizes the antigen on the outside of a pathogen. Each pathogen has a different antigen. That's how it knows what pathogen it is.

∙ 13y agoWell actually they are white blood cells but they are called Lymphocytes (B cells and T cells)
Wiki User
∙ 13y agoThey use a antibody(:
you know you loveee me you know you care<3
Wiki User
∙ 14y agoit uses passive immunity

Are white blood cell pathogen?
No white blood cells are not pathogens, they protect the human body from pathogens.
Any substance that the white blood cells recognize as foreign is known as an?
Pathogen.Pathogens can be things like viruses or bacteria which have things called antigens on them. These antigens are proteins on the pathogen that let the body know that the pathogen is potentially dangerous. This induces the immune response.Hope this helps!
Once the body encounters a pathogen and destroys it what is created?
Once the body activated, killer T cells it recognize pathogen and destroy them. In response that will create memory B cells and T cells specific to a certain pathogen, so if it ever came back it will be killed immediately.
How do white blood cells fight disease?
Pathogens (disease causing agents) are always present in the environment. When they invade in the body, pathogen-destroying white blood cells act as the a line of defense for the body. Macrophages and neutrophiles destroy microorganisms through phagocytosis (engulfing them whole) and are found in the interstitial fluid (outside of the blood stream and cells). The pathogen is drawn into the macrophage where enzymes such as lysozyme kill the pathogen. White blood cells can also identify certain proteins an carbohydrates on the surface of invading pathogen and this recognition triggers the cell's responses. Lymphocytes do not attack directly but instead, they recognize that the cell has become infected by a virus and release antibodies that tags to invader by binding to the antigen molecule. This triggers the mechanism that destroys the invader.
Does the first exposure to a pathogen result in a much faster immune response than the second exposure to the same pathogen?
After your first exposure to a pathogen, you have memory T-cells that will remember the antigen of the pathogen so in the future if you would come in contact with the same pathogen your body would recognize it right away and be able to kill it much faster.
Are white blood cell pathogen?
No white blood cells are not pathogens, they protect the human body from pathogens.
What are the immune system cells that can recognize and commence an attack on a pathogen that has previously infected the individual?
Memory cells

What happens after a white blood cell destroys a pathogen?
The cell will expel the phagosome that the pathogen was in through exocytosis.
How does an immune response starts after a macrophage attacts a pathogen?
The blood cells detect the pathogen The pathogens release toxins The blood cells make antibodies to fit the toxins ( they have to be a specific shape) The antibodies stick the bacteria together ready to be engulfed by he white blood cells The White blood cells remember the antibodies needed for that pathogen so they can make antibodies quicker next time the pathogen invades

Why do white blood cells produce antibodies?
White Blood Cells prouduce antibodies because when a pathogen (another name for a diease) enters your body white blood cells sends out the right antibodies to kill the pathogen and when it is killed the white blood cells remembers it so if the pathogen ever comes back again they know how to get rid of it this is called immunty
How the human immune system fdeals with pathogen?
White Blood Cells
If the same pathogen invades the body twice it will be recognized and destroyed more quickly the second time because of what?
Memory B cells act like an internal vaccine because once it fights the pathogen off it will recognize it. This is how they make vaccines because they inject you with a small amount of the pathogen not enough to harm you so your memory B cells recognize it.
The body's natural way of responding when invaded by a pathogen is?
White blood cells will attack the pathogen which can cause swelling and fever.
Why are there particles not absorbed by blood vessels?
it is not absorbed because of dead cells, or pathogen!
Is HIV a bloodborne pathogen?
Yes, it primarily exists in the circulatory system and destroys T-cells. This is why blood transfusions are checked for HIV/AIDS.
