The invention provides a novel approach to increase immunoglobulin expression in non-human transgenic animals. For instance, the invention provides a method to increase humanized immunoglobulin production in animals genetically engineered to express one or several human or humanized immunoglobulin transloci. This can be done by overexpressing the apoptosis inhibitor, i.e. a rabbit bcl-2, whose expression is driven by a B-cell specific promoter specifically in the B-cell of the animal, thereby enhancing the survival of B-cells. This invention further relates to a method for selectively enhancing the survival of exogenous B-cells, that is B-cells expressing any immunoglobulin transgene locus, over the survival of endogenous B-cells that do not express the transgene locus. Selectivity is achieved by expressing the apoptosis-inhibitor only within exogenous B-cells, that is, by coupling exogenous immunoglobulin expression with apoptosis inhibitor expression. This latter method allows for increased expression and production of the transgene encoded product(s) over the endogenously produced immunoglobulin of the transgenic animal. The invention also provides a novel apoptosis-inhibitor, rabbit bcl-2.
