Serological testing is based on the fact that antibodies react specifically with an anigen all bacteria have the same antigens or the human body makes antibodies against bacteria?
AnswerThe human body makes specific antibodies to specific antigens (ex. proteins on a bacterial membrane) that it encounters. Bacteria do not all have the same antigens.* antibodies react specifically with an antigen
What is h and o antigens?
H antigens correspond to the antigenic type of the bacterial flagellaO antigens correspond to the antigenic type of the Lipopolysaccharide layer on the outer membrane of gram negative bacteriabacteria all have different antigenic types on their surface which react to different types of antibodies and are classified using this method. For example the pathogenic E. coli O157:H7 has the designation 157 for its O antigen meaning it will not react with antibodies with a different serotype.
To what do antibodies respond?
Antibodies are secreted by a special group of white blood cells called lymphocytes. Each type of cell (including bacteria) has a unique protein on its cell membrane - an antigen. If a lymphocyte does not recognise a particular antigen, it will assume that the cell (or bacterium) is foreign and hostile. This is what antibodies respond to - the stimulus as the result of an unfamiliar cell. The antibodies attach to the antigens and kill the cell, or bacterium.
Where are the blood antigens A B Rh located?
The blood antigens A, B, and Rh are located on the membrane of the red blood cell. These antigens are hereditary.
The antigens of the ABO blood group are located in the?
on the surface of the RBC membrane
What is the name of a surface membrane molecule that causes an immune reaction?
Antigens are surface membrane molecules that cause an immune reaction.
The cell types that are most responsible for presenting foreign antigens together with surface antigens to specific receptors on the membrane of T lymphocytes are the macrophages and?
dendritic cells
Can an antibody penetrate the host cell to bind intracellular antigen?
The majority of antibodies bind secreted or membrane bound antigens and do not penetrate cells. Antibodies can be taken up into cells via endocytosis. However, a subset of autoantibodies isolated from autoimmune diseases in humans and mouse models are able to penetrate cells and bind to their antigen in the cytoplasm or nucleus (e.g. anti-DNA autoantibodies).
How a T cell and B cell work together to produce antibodies?
T cells will first have to be activated by peptide presentation on MHC class II and differentiate into T helper 2 cell and T helper 2 cell will secrete cytokines IL-4, IL-5 to help B cell differentiate into a plasma cell.
Substance that determines blood types is found in the membrane of red blood cells?
Antigens. Your blood type depends if you have A, B, AB, or none of those antigens (O). These antigens can also be positive or negative depending on whether you have the Rh antigen, or Rh factor.
What is a basic structure of a cell membrane?
It is a lipid bilayer with proteins floating in it.
Where are the antigens of the ABO blood group are located?
They are found on the cell membrane of every cell, and help to distingish 'self' cells from 'non self' cells
