MAMMALIAN PHENOTYPE - ANNOTATIONS

The Mouse Adult Gross Anatomy Ontology and Mammalian Phenotype Ontology are downloaded weekly from the Mouse Genome Informatics databases at Jackson Laboratories (ftp://ftp.informatics.jax.org/pub/reports/index.html). For more information about these ontologies, see the MGI Publications Page at http://www.informatics.jax.org/mgihome/other/publications.shtml.

Definition:absence of lymphocytes that expresses membrane-bound antibody, and differentiate into antibody-secreting plasma cells and memory cells upon interaction with antigen; B cells are the primary lymphocyte responsible for humoral immunity, and are most effective against extracellular pathogens
