Isoantibodies, formerly called alloantibodies, are antibodies produced by an individual against isoantigens produced by members of the same species.In the case of the species Homo sapiens, for example, there are a significant number of antigens that are different in every individual.

CD19 is widely expressed during all phases of B cell development until terminal differentiation into plasma cells. During B cell lymphopoiesis, CD19 surface expression starts during immunoglobulin (Ig) gene rearrangement, which coincides during B lineage commitment from hematopoietic stem cell. [8]
An illustration that shows how antigens induce the immune system response by interacting with an antibody that matches the molecular structure of an antigen. In immunology, an antigen (Ag) is a molecule, moiety, foreign particulate matter, or an allergen, such as pollen, that can bind to a specific antibody or T-cell receptor. [1]
In immunology, clonal deletion is the process of removing T and B lymphocytes from the immune system repertoire. [1] [2] The process of clonal deletion helps prevent recognition and destruction of the self host cells, making it a type of negative selection. Ultimately, clonal deletion plays a role in central tolerance. [3]
There he became distinguished professor of immunology and director of Center of the Molecular Immunology and Infectious Disease. Subsequently, he moved to the Cornell University College of Veterinary Medicine, where he is a professor at the Department of Microbiology & Immunology, Howard Hughes Medical Institutes- HHMI Professor , [ 15 ] and ...
In immunology, central tolerance (also known as negative selection) is the process of eliminating any developing T or B lymphocytes that are autoreactive, i.e. reactive to the body itself. [1] Through elimination of autoreactive lymphocytes, tolerance ensures that the immune system does not attack self peptides . [ 2 ]
Polyclonal response by B cells against linear epitopes [1] Examples of substances recognized as foreign (non-self). Polyclonal B cell response is a natural mode of immune response exhibited by the adaptive immune system of mammals.
