Anand PK, 2010, Exosomal membrane molecules are potent immune response modulators., Commun Integr Biol, Vol: 3, Pages: 405-408
Exosomes are endosome-derived vesicles (40-100 nm) formed during the formation of multi-vesicular bodies (MVBs). Occasionally, the MVBs fuse with the plasma membrane releasing their intra-luminal vesicles into the extracellular media, which are then known as exosomes. Different cell types such as B-cells, dendritic cells, platelets, reticulocytes and macrophages can release exosomes and current research in this area is more focused towards exosomes released by antigen-presenting cells. Exosomes have recently been shown to be immunomodulatory and the mechanism of immune response initiation by them is beginning to emerge. Besides molecules present inside the lumen of exosomes, it has been suggested that certain exosomal membrane molecules can interact with their surface receptors on the target cells thereby inducing an immunomodulatory response. In this review, Hsp70 and galectin-5, two immunogenic molecules present on exosomal membrane, are discussed in detail for initiating this response.

Anand PK, Kaul D, Sharma M, 2006, Green tea polyphenol inhibits Mycobacterium tuberculosis survival within human macrophages., Int J Biochem Cell Biol, Vol: 38, Pages: 600-609, ISSN: 1357-2725
Lack of maturation of phagosomes containing pathogenic Mycobacterium tuberculosis within macrophages has been widely recognized as a crucial factor for the persistence of mycobacterial pathogen. Host molecule tryptophan-aspartate containing coat protein (TACO) has been shown to play a crucial role in the arrest of such a maturation process. The present study was addressed to understand whether or not polyphenols derived from green tea could down-regulate TACO gene transcription. And if yes, what impact TACO gene down-regulation has on the uptake/survival of M. tuberculosis within macrophages. The reverse-transcriptase polymerase chain reaction and reporter assay technology, employed in this study, revealed that the major component of green tea polyphenols, epigallocatechin-3-gallate had the inherent capacity to down-regulate TACO gene transcription within human macrophages through its ability to inhibit Sp1 transcription factor. We also found out that TACO gene promoter does contain Sp1 binding sequence using bioinformatics tools. The down-regulation of TACO gene expression by epigallocatechin-3-gallate was accompanied by inhibition of mycobacterium survival within macrophages as assessed through flow cytometry and colony counts. Based on these results, we propose that epigallocatechin-3-gallate may be of importance in the prevention of tuberculosis infection.

Using human promyelocytic leukaemic HL-60 cell line as an archetype model, the present study was addressed to understand the role of Receptor-C k in the modulation of sterol-response element (SRE) having DR-3 locus in the promoter region of HMGCoA reductase gene. Such a study unambiguously revealed that Receptor-C k has the inherent capacity to regulate this SRE sequence in HL-60 cells. Based upon this study as well as our earlier findings, it is proposed that Receptor-C k -dependent signalling may be of importance in leukaemogenesis.
