Bach2: plasma-cell differentiation takes a break.
Plasma cells are antibody-producing cells and represent the developmental end point of the B-cell lineage. Over the last few years, major progress has been made in understanding the transcriptional regulation of B-cell to plasmacell transition. Two transcription factors, Pax5 and Blimp1, are responsible for the development and maintenance of B-cell and plasma-cell identity, respectively. Both f...
متن کاملPlasma jet takes off.
Thanks to a series of joint research projects by Los Alamos National Laboratory, Beta Squared of Allen, Texas, and the University of California at Los Angeles, there is now a more environmentally sound method for cleaning semiconductor chips that may also be effective in cleaning up chemical, bacterial, and nuclear contaminants. The Atmospheric Pressure Plasma Jet uses a type of ionized gas cal...
متن کاملATG5 regulates plasma cell differentiation.
Autophagy is a conserved homeostatic process in which cytoplasmic contents are degraded and recycled. Two ubiquitin-like conjugation pathways are required for the generation of autophagosomes, and ATG5 is necessary for both of these processes. Studies of mice deficient in ATG5 reveal a key role for autophagy in T lymphocyte function, as well as in B cell development and B-1a B cell maintenance....
متن کاملCooperative transcriptional repression by BCL6 and BACH2 in germinal center B-cell differentiation.
The transcriptional repressors BCL6 and BACH2 are crucial regulators of germinal center (GC) B-cell fate, and are known to interact and repress transcription of PRDM1, a key driver of plasma cell differentiation. How these factors cooperate is not fully understood. Herein, we show that GC formation is only minimally impaired in Bcl6(+/-) or Bach2(+/-) mice, although double heterozygous Bcl6(+/-...
متن کاملBach2 represses plasma cell gene regulatory network in B cells to promote antibody class switch.
Two transcription factors, Pax5 and Blimp-1, form a gene regulatory network (GRN) with a double-negative loop, which defines either B-cell (Pax5 high) or plasma cell (Blimp-1 high) status as a binary switch. However, it is unclear how this B-cell GRN registers class switch DNA recombination (CSR), an event that takes place before the terminal differentiation to plasma cells. In the absence of B...
