This imparts even greater multiplicity to the overall response. Retrieved from ” https: Consequently, an effective immune response often involves the production of many different antibodies by many different B cells against the same antigen.

Microeconomics Theory Through Applications, v. The collection of various cellstissues immunoloyg organs that specializes in protecting the body against infections is known as the immune system.

Paratope – Wikipedia

It ensures that a single antigen is recognized and attacked through its overlapping parts, called epitopesby multiple clones of B cell. Law of Commercial Transactions, v. In the course of proliferation of this clone, the B cell receptor genes can undergo frequent one in immunology janis kuby pdf download two immunology janis kuby pdf download divisions [8] mutations in the genes coding for paratopes of antibodies.

Pxf from the original on In autoimmunity the immune system wrongly recognizes certain native molecules in the body as foreign self-antigenand mounts an immune response against them. The Journal of Immunology.

Polyclonal B cell response

Principles immunology janis kuby pdf download Microeconomics, v. Antigens can be large and complex substances, and any single antibody can only bind to a small, specific area on the antigen. An alternate pathway of endocytic processing had also been demonstrated wherein certain proteins like fibrinogen and myoglobin can bind as a whole to MHC-II molecules after they are denatured and their disulfide bonds are reduced breaking the bond by immunology janis kuby pdf download hydrogen atoms across it.

As the body needs to be able to respond to a large number of potential pathogens, it maintains a pool of B cells with a wide range of specificities. These frequent mutations are termed somatic hypermutation. Moreover, the same type of white blood cell would express molecules typical to it on its cell membrane at various stages of development.

What makes these substances recognizable is that they bind very specifically and somewhat strongly to certain host proteins called antibodies.
