The change in morphology and behavior of a mature or immature B cell resulting from exposure to a mitogen, cytokine, chemokine, cellular ligand, or an antigen for which it is specific. Any process that modulates the frequency, rate or extent of B cell activation. The process of providing, via surface-bound receptor-ligand pairs, a second, antigen-independent, signal in addition to that provided by the B- or T cell receptor to augment B- or T cell activation. Any process that activates or increases the frequency, rate or extent of lymphocyte activation. 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. Any process that activates or increases the frequency, rate or extent of B cell activation. Any process involved in the development or functioning of the immune system, an organismal system for calibrated responses to potential internal or invasive threats.
