Background & objectives: Despite advances in diagnostics and therapeutics, tuberculosis (TB) is widely prevalent and contributes to a significant burden of illness in both developing and developed nations. The present study was aimed to assess the role of coronin in TB patients and healthy controls. Coronin is a leucocyte-specific protein that is actively recruited in mycobacterial phagolysosomes, where it inhibits lysosomal delivery of Mycobacterium by activating a calcium-dependent phosphatase-calcineurin. Methods: In the study, 100 newly diagnosed cases of TB (pulmonary and extra-pulmonary) and healthy controls were prospectively enrolled over one year and the levels of coronin-1a in these patients and controls were measured by quantitative PCR (qPCR). Results: A total of 100 TB patients and 100 healthy individuals as controls were assessed. There were 59 patients with extra-pulmonary TB (EPTB) and 41 of pulmonary TB (PTB). In 47 per cent of patients, corroborative histopathological evidence of TB was also available. Significantly higher values of coronin-1a were observed in TB patients (19.94±2.61) than in healthy controls (16.09±1.91) (P<0.001). Interpretation & conclusions: Coronin 1a appears to play an important role in the TB disease pathophysiology and agents developed against coronin may have a role in the treatment of TB. Further studies are required to assess if coronin-1a levels are elevated in non-tubercular infective a etiologies and whether these can be a potential drug target in patients with TB.
