Cre driver mice for B cell lineage
B cell-specific and efficient Cre-mediated recombination activity in CD19-iCre line.
|B cells are one of the acquired immune cells that play an important role in humoral immunity against pathogens. B cells are derived from hematopoietic stem/progenitor cells in the bone marrow and differentiate into appropriate forms by interactions with immunoglobulin genes and transcription factors. B cells are also involved in the immune response through antibody production, antigen presentation, and secretion of inflammatory cytokines. B cells have also been reported to function as negative regulators of immunity through anti-inflammatory cytokines such as IL-10 and IL-35.
CD19-iCre knock-in mouse (RBRC11522) is a Cre driver mouse that expresses iCre in B cells. A T2A-iCre cassette is inserted in-frame just before the 3′ terminal stop codon of Cd19. Mating with a Cre-reporter strains have been shown to induce highly efficient Cre/loxP recombination throughout B cell lineage from the early B cell stages. Elucidation of the differentiation process and function of B cells and the related molecular network is important not only in the field of basic immunology but also in the clinical aspect. Therefore, effective use of this CD19-iCre knock-in strain is expected.
