The class of immunoglobulin to respond to the fist exposure of an antigen is immunoglobulin class M (IgM). While Immunoglobulin G (IgG) would predominate on the second exposure.
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.
What is the first step of the immune response?
antigen
Is T cell activation antigen specific?
Yes. The first signal that a T cell receives from an antigen presenting cell (dendritic cell) is MHC presenting an antigen (foreign peptide). This gives the T cell specificity to this antigen.
What is an IgM antibody?
IgM is produced upon initial exposure to an antigen. For example, when a person receives the first tetanus vaccination, antitetanus antibodies of the IgM class are produced 10 to 14 days later. IgM is abundant in the blood.
The type of antibody that is secreted first after the arrival of an antigen?
Lgm
What is the class of antibody first secreted in response to a new antigen?
IgM.
What is the first antibody made in response to an antigen?
IgM is the antibody first secreted during primary response
The term Rh is used because the antigen was first discovered in the blood of a?
