Resumen en ingles
The production of interferon γ (IFNγ) guarantees effective T cell-mediated immunity against Mycobacterium
tuberculosis infection. In the present study, we simply compare the in vitro immune responses to Mycobacterium
antigens in terms of IFNγ production in a total of 10 healthy Brazilian volunteers. Whole blood and mononuclear
cells were cultivated in parallel with PPD, Ag85B, and M. bovis hsp65, and five-days supernatants were harvested
for cytokine detection by ELISA. The inter-assay result was that the overall profile of agreement in response to
antigens was highly correlated (r2 = 0.9266; p = 0.0102). Potential analysis is in current progress to dictate the
usefulness of this method to access the immune responses also in tuberculosis patients and its contacts.
