Selleckchem PFT�� Background Mycobacterium tuberculosis is one of the leading causes of death due to a single infectious agent. Its success is based on perfect adaptation to the human host

and the conditions prevailing in infected cells and tissues such as hypoxia, nutrient starvation, low pH and the presence of antimicrobial substances. By adapting their gene expression, growth and metabolism to these environmental conditions, the bacteria are able to persist over long periods of time inside immune cells within granuloma in a latent Carbohydrate state until possible reactivation and outbreak of disease. To be able to combat the disease, it is necessary to understand the molecular mechanisms regulating mycobacterial intracellular persistence, latency

and reactivation. A class of proteins implicated in regulating latency are the mycobacterial histone-like proteins (Hlp) [1]. Hlp have been identified in pathogenic as well as environmental mycobacteria [2, 3]. Proteins belonging to this class have been given different designations in different mycobacterial species such as HLPMt or HupB in M. tuberculosis[3, 4], MDP1 (mycobacterial DNA-binding protein 1) in Mycobacterium bovis BCG [5], Hlp in Mycobacterium smegmatis[2] and ML-LBP21 in Mycobacterium leprae[6]. They are composed of an extremely basic C-terminal part homologous to eukaryotic histone H1 and an N-terminal region similar to HU from Escherichia coli[3, 5]. Hlp expression is developmentally regulated and up-regulation was observed in dormant M. smegmatis[2] and stationary cultures from M. bovis BCG [5]. It is an immunogenic protein detectable in tuberculosis patients [7].
