Interestingly, in contrast with that observed with the local and peripheral IFN-γ responses, IgA levels showed a positive and highly significant correlation (correlation coefficient: 0.68, p < 0.001), with the specific-IgG levels in serum by the endpoint of the experiment and to a lesser extent with the peripheral cellular immune response, measured with the IGRA test (correlation coefficient: 0.55, p < 0.01) ( Figure 10D ). 4.
