Which class of antibody accounts for the bulk of circulating antibody?
Igg
Antibody molecules consists of how many polypeptide chains depending on which class of antibody is considered?
two
Function of plasma cell?
On B-cell activation by antigen, it proliferates into antibody secreting plasma cells and memory cells. Plasma cells function in adaptive immunity. Specific secreted antibodies by plasma cells then bind to extracellular microbes, block their ability to infect host cells and promote their ingestion and subsequent destruction by phagocytes.
What is the class of antibody first secreted in response to a new antigen?
IgM.
What is the Role of a variable region of an antibody molecule?
Each antibody has a variable region at the top of the arms of the Y-Shaped structure of the antibody. These variable regions each have a different sequence of amino acids and therefore a different structure. This means that only specific antigens can bind to the binding sites - only those with a complementary shape. The antigen fits into the binding site by induced fit. Once the antigen has bound to the antibody it forms a highly specific antigen-antibody complex. Therefore the role of the variable region is to produce a specific binding site for each type of antigen.
How do phagocytes recognize foreign cells or bacteria?
Lymphocytes are part of the human body's innate immune system. Natural killer cells seek out and destroy foreign cells by distinguishing surface molecules of major histocompatibility complex class.
Class II MHC molecules are found only on which of the following?
Presented by APCs as MHC-exogenous peptide complex
B cells are primarily activated by the activities of A antigens B macrophages C helper T cells D antibodies E plasma cells?
Antibodies are produced by B lymphocytes. An antibody is a class of proteins produced by B lymphocytes, sometimes known as B cells. To neutralize diseases or foreign substances like poisons, these antibodies bind to them. For instance, an antibody can attach to a virus, preventing it from infecting a healthy cell and spreading. B cells can enlist the aid of other cells in the fight against an infected cell. Central BioHub offers thousands of B cells collected from patients and healthy donors for research.

What proteins on surface of cells have carbohydrates attached to protein?
At the heart of the immune response is the ability to distinguish between "self" and "non-self." Every cell in your body carries the same set of distinctive surface proteins that distinguish you as "self." Normally your immune cells do not attack your own body tissues, which all carry the same pattern of self-markers; rather, your immune system coexists peaceably with your other body cells in a state known as self-tolerance. This set of unique markers on human cells is called the major histocompatibility complex (MHC). There are two classes: MHC Class I proteins, which are on all cells, and MHC Class II proteins, which are only on certain specialized cells.
Where are major histocompatibility complex-you MHC-you molecules located?
Each individual has a unique MHC profile Clinically important MHC are HLA(human leukocyte antigens) -A, -B -DR -expression of a particular combination of MHC genes Class I - are located on all nucleated cells Class II - are located on macrophages, dendritic cells, B cells.
Which antibody class neutralizes viruses in the intestinal tract?
I would assume IgA class antibodies. The intestinal tract is lined with mucous membranes and the IgA class is primarily secreted through mucous.
What class of antibody is produced in the primary immune response?
The class of immunoglobulin that is produced in the primary immune response is Immmunoglobulin M (IgM). On secondary exposure, the class that predominates would be Immunoglobulin G (IgG).
