Abstract
Trehalose-6-phosphate phosphatase is an enzyme strictly essential for the growth of mycobacteria. Subcellular fractionation of Mycobacterium tuberculosis and M. bovis bacillus Calmette-Guérin (BCG) located the trehalose-6-phosphate phosphatase in the cell wall and membrane fractions. Trehalose-6-phosphate phosphatase induced an increased Th1-type immune response in mice, characterized by an elevated level of interferon-γ in antigen-stimulated splenocyte culture and a strong IgG2a antibody response. The trehalose-6-phosphate phosphatase was recognized by the sera of tuberculosis patients and BCG-vaccinated donors. The mycobacterial trehalose-6-phosphate phosphatase is an immunodominant antigen, and it may be a candidate for vaccine development for the control of tuberculosis.
