Summary of research:
DevR-DevS/DosT signal transduction system of M. tuberculosis.
In the late 1980s when studies on molecular pathogenesis of M. tb were in their infancy, an innovative RNA subtractive hybridization strategy was designed and successfully performed in my laboratory to identify candidate virulence genes of M. tb. This led to the discovery of a two-component signal transduction system (TCS) designated as DevR-DevS. Subsequently, considerable interest in this regulator was generated on account of its role in mediating the bacterial adaptive response to oxygen limitation, a condition thought to prevail within granulomas where dormant M. tb reside.
My laboratory has made fundamental contributions towards characterizing and understanding the role of this signaling system - phosphosignal transfer, promoter mapping, autoregulation, mechanism of transcriptional activation of target genes, characterization of the DevR regulon and cross-talk with the DosT orphan sensor. Furthermore, the level of DevR expression appears to plays a key role in DevR regulon expression, bacterial hypoxic adaptation and virulence in the guinea pig model. A M. tb devR mutant that expresses the N terminal phosphorylation domain (DevRN) effectively interferes with DevR-mediated signaling. This finding suggests a novel approach to assess TCS-mediated signaling in M. tb without having to generate knock out strains.
DevR is a very attractive and hitherto unexplored target for designing anti-dormancy molecules. Ahomology-based model of DevRwas successfully used for the rational design of inhibitors. A phenylcoumarin derivative inhibited DevR binding to target DNA, down-regulated dormancy genes transcription and drastically reduced survival of hypoxic bacterial cultures. Our findings suggest that A-10 ‘locks’ DevR in an inactive conformation which is unable to bind cognate DNA and induce the dormancy regulon. These results provide proof-of-concept for DevR as a novel target to develop molecules with sterilizing activity against tubercle bacilli.
An in vitro model of dormancy was recently developed wherein tubercle bacilli acquire dormancy phenotype in broth cultures and also within infected THP-1 cells. This model is being exploited to dissect into interactions between host and dormant bacteria and it is hoped that the insights from such analysis will suggest novel targets for interception.
The DevRS system is being further characterized using genetic, biochemical and global molecular approaches to understand its place in the bacterial transcription regulatory network.
Improved laboratory diagnosis of tuberculosis - development and validation of novel approaches and technology.
The rapid, sensitive and specific diagnosis of tuberculosis (TB) is a daunting challenge to microbiology laboratories. To suit the requirements of various laboratories for diagnosing pulmonary and extrapulmonary TB, a multipurpose technology named as USP (universal sample processing) technology was developed. It comprises sample processing, highly sensitive smear microscopy, culture and inhibition-free PCR. The utility of the technology has been validated extensively in a variety of clinical samples. The technology is transferred to Industry.
Novel approaches of analyzing post-lysis debris for acid-fast bacilli and sample supernatants for M. tb DNA have improved the diagnosis of paucibacillary TB. A recently concluded study confirmed the utility of CSF filtrates in the diagnosis of TB meningitis. The visual detection of amplified DNA by molecular beacons has further simplified the TB PCR test. A disinfection protocol was successfully combined with USP to provide safe handling of infected samples. The detection of M. tb antigens including HspX, Ag85B etc. in CSF specimens has shown great promise for the rapid and efficient diagnosis of tuberculous meningitis. Studies are ongoing to simplify the DNA and antigen-based assays for TB diagnosis.
