"The process of regulating the proliferation and elimination of B cells such that the total number of B cells within a whole or part of an organism is stable over time in the absence of an outside stimulus [goid 1782] [evidence IEA]; Any process that activates or increases the frequency, rate, or extent of germinal center formation [goid 2636] [evidence IEA]; The cascade of processes by which a signal interacts with a receptor, causing a change in the level or activity of a second messenger or other downstream target, and ultimately effecting a change in the functioning of the cell [goid 7165] [pmid 10908663] [evidence TAS]; Any process that activates or increases the rate or extent of cell proliferation [goid 8284] [pmid 10359578] [evidence TAS]; Any process that activates or increases the rate or extent of B cell proliferation [goid 30890] [evidence IEA]; The process of providing, via surface-bound receptor-ligand pairs, a second, antigen-independent, signal in addition to that provided by the T cell receptor to augment T cell activation [goid 31295] [evidence IEA]; The process of providing, via surface-bound receptor-ligand pairs, a second, antigen-independent, signal in addition to that provided by the B cell receptor to augment B cell activation [goid 31296] [evidence IEA]; Any process that activates or increases the rate or extent of T cell proliferation [goid 42102] [evidence IEA]; Any process that activates or increases the frequency, rate or extent of survival gene product expression; survival gene products are those that antagonize the apoptotic program. Regulation can be at the transcriptional, translational, or posttranslational level [goid 45885] [evidence IEA]; The regulated release of immunoglobulins from a B cell or plasma cell, whose mechanism includes the use of alternate polyadenylylation signals to favor the biosynthesis of secreted forms of immunoglobulin over membrane-bound immunoglobulin [goid 48305] [evidence IEA]; Any process that modulates the frequency, rate or extent of the immune response, the immunological reaction of an organism to an immunogenic stimulus [goid 50776] [evidence IEA]"
