B and T cells that have not yet been exposed to an antigen are referred to as "naive" cells. These cells are mature but have not yet encountered their specific antigen, which is necessary for their activation and differentiation into effector cells. Naive B cells can produce antibodies, while naive T cells can become cytotoxic T cells or helper T cells upon activation.
What else can I help you with?
Which cell develops into a plasma cell?
Stem cells develop into plasma cells and B cells also turn into plasma cells. Plasma cells have been exposed to an antigen and then produces and secretes antibodies.
Who is responsible for antibody production?
Naiive B cells are lymphocytes that have not yet been exposed to antigen. Once it can identify a particular antigen, it will undergo production of antibodies and become a mature B cell. Mature B cells are split into two categories: plasma B cells and memory B cells. Plasma B cells will continue to produce large amounts of antibodies. Memory B cells are stored so that the next time you encounter the same antigen, it can start producing antibodies much quicker because it remembered from the previous encounter.
What is the difference between a antigen and a processed antigen?
An antigen can be anything from virus to bacteria to a soluble protein from outside or inside a cell. This includes both foreign and self peptides. An antibody that finds an appropriate antigen will bind to it and your B and T cells determine if it's self or not. A processed antigen came from cytosol. A protein will be taken by ubiquitin to a proteosome where it is broken up into small peptides. These peptides will make their way into the endoplasmic reticulum (through TAP) where they are exposed to MHC's.
Enhance immune responses to subsequent exposures to an antigen to which the body has already been exposed are know as?
memory responses
What is the term used to describe if a patient has ever had contact with a particular antigen?
The term used to describe if a patient has ever had contact with a particular antigen is "sensitization." Sensitization occurs when the immune system has been exposed to and recognized a specific antigen, leading to an immune response upon subsequent contact with the same antigen.
In Blood type O what does selectogen negative mean?
Selectogen negative in blood type O refers to the absence of a specific antigen called the Selectogen antigen. This antigen is part of the Rh blood group system. Individuals who are Selectogen negative do not have this antigen on their red blood cells, while those who are Selectogen positive do have it.
What is the difference between hepatitis B surface and hepatitis b antigen?
When your body is introduced to the Hepatitis B virus, the virus is considered the antigen (the surface antigen)and this should trigger your immune system to develop antibody against this antigen to destroy it. Most people do develop Hep B surface antibody when infected with the Hep B virus. Some people do not develop the antibodyand go on to have only circulating Hep B surface antigen - which means they are a carrier and can continue to have the virus and infection. For the majority of the population that develop the Hep B surface antibody, this conveys immunity to the virus for life.
Development of a secondary immune response is based on populations of?
Memory B cells and memory T cells, which have been previously exposed to a specific pathogen or antigen. These cells can rapidly recognize and respond to the same pathogen upon re-exposure, leading to a faster, stronger, and more targeted immune response. This is the basis for the faster and more effective immune response seen during a secondary immune response.
What is the difference between soluble and particulate antigen?
A soluble antigen is a viral antigen that remains after the virus has been removed. A particulate antigen is produced by particles such as dust and germs.
What is protective antigen?
Protective antigen is a key component of anthrax toxin, produced by the bacterium Bacillus anthracis. It is essential for the entry of the toxin into host cells and plays a crucial role in the pathogenesis of anthrax infection. Vaccines targeting protective antigen have been developed as a preventative measure against anthrax.
What is the condition called of soldiers exposed to wet and cold conditions?
I have been called "atmospheric".
What is the advantage of having memory cells in specific defenses in that?
Memory cells provide a rapid and robust response to previously encountered pathogens, enhancing the immune system's efficiency. Once the body has been exposed to a specific antigen, memory T and B cells remain dormant and can quickly proliferate and differentiate upon re-exposure, leading to a quicker and more effective immune response. This memory function is the basis for long-lasting immunity, which is crucial for the effectiveness of vaccinations.
