On the other hand, by using pools of overlapping synthetic peptides covering the sequence of RD5-encoded proteins, the CMI responses have been determined, the INF-γ data showed that the 11% responses in pulmonary tuberculosis patients and 2% responses in healthy blood donors, and the IL-10 data showed that the 33% responses in pulmonary tuberculosis patients and 17% responses in healthy blood donors, as discussed by Mustafa and Al-Attiyah [38]. Here, IL10 is linked to pulmonary tuberculosis.
