[Study of a role of B cells in the formation of antituberculosis immunity].

The authors have earlier demonstrated that CBA/N mice bearing nonsense mutation in the btk gene encoding B cell Bruton's thyrosine kinase after CG vaccination develop no protective response against subsequent M. tuberculosis H37Rv challenge. Adoptive transfer approaches are applied to show that this defect is determined by lymphoid cells and B lymphocytes play an essential role in its expression. In addition, experiments on CBA/N-xid mice with crude mixtures of soluble mycobacterial antigens suggest that the processing of live BCG could be impaired in the antigen-presenting cells of these mice.
