Isolated human monoclonal antibodies which bind to IL-8 (e.g., human IL-8) are disclosed. The human antibodies can be produced in a hybridoma, transfectoma or in a non-human transgenic animal, e.g., a transgenic mouse, capable of producing multiple isotypes of human monoclonal antibodies by undergoing V-D-J recombination and isotype switching. Also disclosed are pharmaceutical compositions comprising the human antibodies, non-human transgenic animals, hybridomas, and transfectomas which produce the human antibodies, and therapeutic and diagnostic methods for using the human antibodies.
