Abstract
The temporo-spatial relationship between the three organs (lung, spleen and lymph node) involved during the initial stages
of Mycobacterium tuberculosis infection has been poorly studied. As such, we performed an experimental study to evaluate
the bacillary load in each organ after aerosol or intravenous infection and developed a mathematical approach using the
data obtained in order to extract conclusions. The results showed that higher bacillary doses result in an earlier IFN-c
response, that a certain bacillary load (BL) needs to be reached to trigger the IFN-c response, and that control of the BL is
not immediate after onset of the IFN-c response, which might be a consequence of the spatial dimension. This study may
have an important impact when it comes to designing new vaccine candidates as it suggests that triggering an earlier IFN-c
response might not guarantee good infection control, and therefore that additional properties should be considered for
these candidates.
