title: Heat shock proteins: possible biomarkers in pulmonary and extrapulmonary tuberculosis.
abstract: Tuberculosis (TB) and Tuberculous meningitis (TBM) caused by Mycobacterium tuberculosis (MTB) continue to be a major cause of morbidity and mortality. Therefore there is a need to explore potential biomarkers and heat shock proteins [Hsp(s)] could be one such candidate. We found that host (Hsp 25, Hsp 60, Hsp 70 and Hsp 90) and MTB Hsp(s) (Hsp 16, Hsp 65 and Hsp 71) to be an important feature of the immune response in human clinical samples of pulmonary and extrapulmonary TB patients and in MTB infected monocytes. Notably, the host (Hsp 25, Hsp 70 and Hsp 90) and MTB (Hsp 16, Hsp 65 and Hsp 71) Hsp(s) increases significantly in the clinical samples as well as in cell line model after TB infection. Collectively, results revealed that alteration in immune response leads to a change in the both host and MTB Hsp profile, highlighting them as possible biomarkers for the disease.
