Responses Mediated Downregulation of B Cell
... Recently, another mature B cell subset that accumulates with age has been described and called age-associated B cells (ABCs), because they represent 10–30% of the peripheral B cell pool in C57BL/6, BALB/c, (BALB/c 3 C57BL/6) F1, and DBA/2 mice $22 mo of age (27). These cells were shown to be CD19+AA ...

Regulation of Ribosome Biogenesis by the Rapamycin
... Rapamycin combines with the immunophilin FKBP and inhibits a large molecular weight protein termed mTOR (mammalian target of rapamycin), also known as FRAP (Thomas and Hall, 1997). This protein has homology to a novel family of PI-3 kinase–related kinases, whose members include Mec1, Rad3, and DNA-d ...
