Analysis of Mtb H37Rv-infected THP-1 macrophages treated with the hormonal form of vitamin D (1,25D). Macrophages are the primary site of Mtb infection and are sites of 1,25D signaling. Results provide insight into the molecular basis of the 1,25D-enhanced macrophage response to Mtb infection.

(Submitter supplied) As macrophages are the primary site of Mtb infection and are sites of vitamin D signaling, we have used these cells to understand the molecular mechanisms underlying modulation of the immune response by the hormonal form of vitamin D, 1,25-dihydroxyvitamin D (1,25D). Microarrays were used to measure the changes in gene expression induced by 1,25D treatment of H37Rv-infected THP-1 cells

(Submitter supplied) We investigated the molecular mechanisms by which colchicine regulates host defense in macrophages against M. tuberculosis infection. To elucidate this, we performed global gene expression analysis of M. tuberculosis infected-bone marrow-derived macrophages after colchicine treatment.

(Submitter supplied) Previous reports have shown low vitamin D serum levels and polymorphisms in the vitamin D receptor (VDR) to be associated with increased risk for TB. Given that 1α,25-dihydroxyvitamin D3 has a role in lipid metabolism control, we tested whether the link between 1α,25-dihydroxyvitamin D3 and tuberculosis involves macrophage lipid metabolism. Since formation of lipid droplets (LD) is a hallmark of lipid dysregulation in M. more...

(Submitter supplied) A role for vitamin A in host defense against Mycobacterium tuberculosis has been suggested through epidemiological and in vitro studies; however, the antimicrobial mechanism is unclear. Here, we demonstrate that vitamin A mediates host defense through regulation of cellular cholesterol content. Comparison of monocytes stimulated with all-trans retinoic acid (ATRA) or 1,25-dihydroxyvitamin D3, the biologically active forms of vitamin A and vitamin D respectively, indicates that ATRA and 1,25D3 induce mechanistically distinct antimicrobial activities. more...

(Submitter supplied) Vitamin D may have anti-tumorigenic actions by influencing the gene expression profile of target tissues, which possess vitamin D receptors. We used a more physiological in vitro model, represented by short-term culture of breast cancer tissue slices, to study the transcriptional effects of a near physiological concentration of calcitriol. Methods. Breast cancer fragments were sliced and maintained in culture for 24 hours in the presence or absence (control) of calcitriol 0.5nM or 100nM (called physiological or supra-physiological concentrations). more...

(Submitter supplied) Tuberculosis remains a major cause of death from an infectious disease worldwide, yet only 10% of people infected with Mycobacterium tuberculosis develop disease. Defining both necessary and sufficient immunologic determinants of protection remains a great scientific challenge. Analysis of peripheral blood gene expression profiles of active tuberculosis patients has identified correlates of risk for disease or pathogenesis. more...

(Submitter supplied) This study characterizes the genetic basis of variation in the immunomodulatory effects of the active form of vitamin D, 1,25-dihydroxyvitamin D3 (1,25D). This was done by mapping quantitative traits of 1,25D response both at the cellular and transcriptional level in peripheral blood mononuclear cells (PBMCs).

(Submitter supplied) This experiment is to compare the transcription patterns of mouse macrophages (J774A.1) infected with BCG, H37Ra and M. smegmatis under high multiplicity of infection (MOI). Through the global transcriptome profiling study, we define a pathogen specific host gene expression pattern and indicate that SRC likely plays a central role in regulating multiple unique signaling pathways activated by MTB infection. more...

(Submitter supplied) Tuberculosis (TB) caused by infection with Mycobacterium tuberculosis (Mtb) is characterized by inflammatory pathology and poorly understood mechanisms of innate immunity. Pattern recognition receptors (PRR), expressed on the surface of macrophages, determine the balance of inflammatory and antimicrobial functions that influence disease outcome. Carbohydrate moieties displayed by mycobacteria can serve as PRR ligands for some members of the C-type lectin receptor (CLR) family; interactions that mediate a variety of incompletely understood immune outcomes. more...

(Submitter supplied) Co-culture of platelets with monocytes induces the forming of multinucleated giant foam cells (MP-Mac or MP-MNGCs). Compared with normal monocyte differentiated macrophages (M-Mac), the MP-MNGCs can engulf more mycobacteria with suppressed inflammatory responses (releasing more IL-10 with less TNF-gamma). Microarray analysis demonstrated that the MP-MNGCs greatly up-regulated CXCL5, PPBP, NT5E, PDPN, CXCL3 and other M2 related genes, such as ARG1, CXCL1, CD163, etc. more...
