In the context of spinal tuberculosis a study of the inflammatory responses of human multinucleated osteoclasts infected with virulent Mtb is of interest. Intracellular Mtb infection resulted in the rapid growth of Mtb and production of proinflammatory cytokines. In contrast, highly-fused multinucleated osteoclasts incapacitated the production of these cytokines, Mtb escaped from the endosome/phagosome, and led to a different pattern of osteoclast activation with the production of a set of chemokines. These findings indicate that intracellular Mtb infection in multinuclear osteoclasts reprograms osteoclast development via the dysregulation of cytokines and chemokines.
