Blood containing antigen B on the surface of the cell and anti-A antibodies in the plasma would be blood type?
Blood containing antigen B on the surface of the cells and anti-A antibodies in the plasma would be classified as blood type B. This type has B antigens on red blood cells and produces antibodies against A antigens, which means it cannot accept type A or AB blood without causing an immune reaction. Thus, individuals with this blood type can safely receive type B or type O blood.
What else can I help you with?
Do plasma cells develop from t cells after exposure to an antigen?
No, plasma cells develop from B cells after exposure to an antigen. T cells play a role in activating B cells to differentiate into plasma cells and produce antibodies. Plasma cells are responsible for producing large amounts of antibodies specific to the antigen encountered.
How do cells involved in the humoral response respond to antigen presentation on the surface of a B cell?
Helper T cells recognize the receptor-antigen complex and cause plasma and memory cells to be produced to then produce antibodies.
Antigens cause immature B cells to?
When a B cell detects an antigen, it will engulf it and then display it on its cell surface with an MHC molcule. This antigen/MHC combination is then detected by a T cell - which will send signalling molcules to B cells to multiply and mature into plasma cells (which create antibodies against the antigen) and memory B cells (which 'remember' the antigen for next time).They become plasma cells
A person with type A blood has antibodies to?
Type A blood will produce antibodies against B antigens.
What needs to form antibodies?
antibodies-part of humoral immunity involving B cells are formed in response to a foreign antigen by plasma cells
How are antibodies form?
Antibodies are formed as the defence against antigen or pathogen which is consider as a foreign particle by body against whcih body immune system acts. Antibodies are formed my activated B cells called plasma cell and are made of glycoproteins
Which of the following initiates an attack against a specific antigen or pathogen?
Plasma Cell initiate attacks against specific antigens. Plasma cells are B cells bearing specific antibodies for binding to a specific antigen.
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.
What statement about the immune system is false?
Plasma cells proliferate and produce antibodies against an antigen during humoral immunity.
What is the function of the plasma cell?
produce antibodies Plasma cells are antibody-manufacturing cells derived from B lymphocytes, following their activation by an antigen. They are responsible for humoral immunity - immunity conferred by antibodies present in the blood plasma. Plasma cells are capable of synthesising and secreting antibodies at a rate of 2000 molecules per second. Each cell will only synthesise and secrete one type of antibody. This antibody will bind specifically to the antigen that initially activated the precursor B lymphocyte. Plasma cells will synthesise and secrete antibody molecules over their short life span of 4 to 5 days. The secreted antibodies circulate in the blood or lymph and bind to their complementary antigen, thus marking them for destruction by other mechanisms.
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.
How b cell responds to the initial antigen challenge?
Upon initial antigen challenge, B cells with specific surface receptors that match the antigen become activated. These activated B cells differentiate into plasma cells that produce antibodies targeting the antigen. Additionally, some B cells can also become memory B cells to mount a faster and more robust immune response upon subsequent exposures.
