(Submitter supplied) Since macrophage activation can now be studied at a global level using modern microarray and proteomic analyses, discovery of novel macrophage activation genes is inevitable and important for understanding HIV-associated dementia (HAD). We isolated two different types of primary human macrophages, microglia and monocyte-derived macrophages (MDM) from brain tissue and whole blood respectively. The microarray analysis of differentially regulated macrophage activation genes reported here supports our previous assertions that the mixed glia (MIX) cultured in starvation conditions (DMEM alone) are a non-activated, or “quiescent”, tissue culture model for studying macrophage activation in the brain. more...

(Submitter supplied) Prolonged use of glucocorticoids can lead to the formation of a cataract, however the mechanism is not known. We recently reported the presence of the functional glucocorticoid receptor in immortalized cultured mammalian lens epithelial cells (Gupta & Wagner, Invest Ophthalmol Vis Sci 2003), but the short term biological effect of glucocorticoid action in lens epithelial cells is not known. This study seeks to examine glucocorticoid induced changes in global gene expression in LECs. more...

(Submitter supplied) d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxicity) in brain tissue. The transcriptomic changes that occur in the brain after d-serine exposure have not been fully explored. more...

(Submitter supplied) Primary open angle glaucoma (POAG) is a progressive optic neuropathy, which is a major cause of worldwide visual impairment and blindness. Pathological hallmarks of the glaucomatous optic nerve head include retinal ganglion cell axon loss and extracellular matrix (ECM) remodeling of the lamina cribrosa layer. TGF-beta is an important pro-fibrotic modulator of ECM metabolism, whose levels are elevated in human POAG lamina cribrosa tissue compared with non-glaucomatous controls. more...

(Submitter supplied) The mechanical effect of raised intraocular pressure is a recognised stimulus for optic neuropathy in primary open angle glaucoma (POAG). Characteristic extra-cellular matrix (ECM) remodelling accompanies axonal damage in the lamina cribrosa (LC) of the optic nerve head in POAG. Glial cells in the lamina cribrosa may play a role in this process but the precise cellular responses to mechanical forces in this region are unknown. more...

(Submitter supplied) Phenotypic and functional diversity between macrophage subpopulations reflects their plasticity to respond to microenvironmental signals. Apart from detecting differences in expression profiles, the comparison of the transcriptomes of different macrophage populations may also allow the definition of molecular similarities between these subsets. Transcriptome analysis of human Kuppfer cells, alveolar, splenic and atherosclerotic plaque residing macrophages using microarrays, identified 42 genes that are specifically expressed in atherosclerotic plaque macrophages. more...

(Submitter supplied) We compare, in human macrophages, stimuli considered to induce M1 or M2 type of activation, also termed classical and alternative activation. This dataset highlights key differences between the M1 and M2 stimuli pointing to the need of a revision of the paradigm. Macrophages were left untreated or stimulated with IL-4 and IL-13 (prototypic M1 stimuli), Dexamethasone (Glucocorticoid receptor agonist) which has been hitherto considered M2, IL-10 which also falls under the M2 umbrella, and LPS and Interferon Gamma considered M1 stimuli. more...

(Submitter supplied) Analysis of alternative activation of macrophages at gene expression level. The study forms part of a wider study where we compare the effects of IL-4 in different human and mouse macrophages. Our results support the notion that in vitro culture conditions greatly affect the macrophage response to IL-4. Total RNA obtained from Thioglycollate and Biogel elicited peritoneal macrophages exposed to 20 ng/ml of IL-4 for 18 hours.
