What are the cells that stay young not elongating not differentiating?
The correct answer is meristems.
Hemagglutination-inhibition test description?
It is the measures of the ability of soluble antigen to inhibit the agglutination of antigen-coated red blood cells by antibodies. In this test, a fixed amount of antibodies to the antigen in question is mixed with a fixed amount of red blood cells coated with the antigen (research on passive hemagglutination). Also included in the mixture are different amounts of the sample to be analyzed for the presence of the antigen. If the sample contains the antigen, the soluble antigen will compete with the antigen coated on the red blood cells for binding to the antibodies, thereby inhibiting the agglutination of the red blood cells.
Cell mediated immunity anatomy definition?
Immunity independent of antibody but dependent on the recognition of antigen by T cells and their subsequent destruction of cells bearing the antigen or on the secretion by T cells of lymphokines that enhance the ability of phagocytes to eliminate the antigen.
When IL-2 is secreted by antigen-specific T cells activated due to presentation of antigen by APCs What happens to naive antigen-nonspecific T cells in the vicinity?
They proliferate due to their exposure to IL-2
Do plasma cells develop from t cells after exposure to an antigen?
Plasma cells develop from b cells.
What type of cells makes blood cells?
antigen
How do B cells respond to the initial antigen challenge?
B cells respond to the initial antigen challenge by producing progeny cells. The progeny cells include both memory cells and plasma cells.

What is the function of an antigen in an antigen-antibody response?
To help immune cells identify and destroy a pathogen
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
When IL-2 is secreted by antigen-specific T cells activated due to presentation of antigen by APCs What happens to naive antigen-nonspecific T cells in the vicinity?
They proliferate due to their exposure to IL-2
Antigen presenting cell?
Antigen-presenting cells display foreign antigens on the cell surface with the hopes of T cells noticing recognizing these complexes. The cells that do this on a routine basis are called Professional APC's. This group consists of dendritic cells, macrophages, B-cells, and certain activated epithelial cells.
Do plasma cells develop from t cells after exposure to an antigen?
Plasma cells develop from b cells.
If the anti-A antibody causes blood to coagulate which antigen would be present on the red blood cells?
a
The clumping of cells that occurs as a result of an antigen-antibody reaction is called?
When an antigen and antibody react it causes cells to clump together. The term used to describe the clumping of cells is called agglutination.
