In humans, most of circulating Ig are produced by bone marrow plasma cells. PCs differentiate from activated nai?ve or memory B-cells usually activated by specific antigens. It is still controversial whether the regulation of PCs numbers and the "active" in vivo Ig diversity depend or not on non-specific reactivation of B-cells during infections. Depending on the stimulus (T-independent/T-dependent antigen, cytokines, partner cells) and B-cell types (nai?ve or memory, circulating or germinal center, lymph nodes or spleen, B1 or B2...), both the phenotype and isotype of PCs differ suggesting that PC diversity is either linked to B-cell diversity or to the type of stimulus or to both. Knowledge of the mechanisms supporting PC diversity has important consequences for the management of i) plasma cell neoplasia such as Multiple Myeloma and Waldenstro?m's Macroglobulinemia, ii) vaccine protection against pathogens and iii) auto-immune diseases. 606 $aMedicine$2bicssc 610 $aAutoimmunity 610 $aAutophagy 610 $aB-cell 610 $aB1 610 $aCell Cycle 610 $adifferentiation 610 $aIL21 610 $aMyeloma 610 $aPlasma cell 615 7$aMedicine 700 $aDefrance$b Thierry$4auth$01837976 702 $aPellat-Deceunynck$b Catherine$4auth 906 $aBOOK 912 $a9910136792003321 996 $aThe Origin of the Plasma Cell Heterogeneity$94416852 997 $aUNINA
