Human retinal pigment epithelial (HRPE) cells in culture respond to inflammatory cytokines (IFN-? + TNF-? + IL-1? ) by increasing the expression of many cytokines and chemokines. The goal of this study was to delineate the role of miRNA in this process. We employed microarray analysis to study the e...

Retinal pigment epithelium (RPE) cells can be obtained through in vitro differentiation of both embryonic stem cell (ESC) and induced pluripotent stem cells (iPSC) for cell replacement therapy. We have previously identified 87 signature genes relevant to RPE cell differentiation and function through...

Using the paradigm of in vitro differentiation of hESCs/iPSCs into retinal pigment epithelial (RPE) cells, we have recently profiled mRNA and miRNA transcriptomes to define a set of RPE mRNA and miRNA signature genes implicated in directed RPE differentiation. In this study, in order to understand t...

To identify disease-specific transcriptional programs in retinal pigment epithelium (RPE) cells, fibroblasts from 43 patients with geographic atrophy (GA) were reprogrammed into induced pluripotent stem cells (iPSCs) before being differentiated into RPE and compared to those from 36 healthy individu...

Ocular pigment epithelium (PE) cells promote the generation of T regulators (PE-induced Treg cells). Moreover, T cells exposed to PE acquire the capacity to suppress the activation of bystander T cells via TGFbeta. Membrane-bound TGFbeta on iris PE cells interacts with TGFbeta receptors on T cells, ...

The retinal pigment epithelium (RPE) is a polarized cell layer that is critical for photoreceptor function and survival. It’s unique relationship to the photoreceptors and its specific physiology makes the RPE a critical determinant of human vision. Therefore we performed global expression profil...

We generated hiPSCs from patients fibloblast with retinitis pigmentosa (RP) using retrovirus and Sendai virus vectors, which we differentiated into hiPSC derived retinal pigment epithelium using two different methods (SDIA and SFEB methods). We investigated whether these hiPSC-RPE colonies, which we...

Our purpose was to investigate genes and molecular mechanisms involved in patients with Leber congenital amaurosis (LCA). Fibroblasts from two unrelated clinically-identified patients (Coriell) were reprogrammed to pluripotency by retroviral transduction. These human induced Pluripotent Stem Cells (...

We have used surgical specimens to perform a differential analysis of the transcriptome of human retinal tissues following detachment. Data analysis reveals major involvement of the immune response in the disease and interindividual variation was monitored to unravel a second crucial aspect of the p...

Palmitoylation is a dynamic process which regulates the activity of the modified proteins. Retinal pigment epithelial (RPE) cells play pivotal roles in visual cycle and maintaining healthy photoreceptor cells. Dysfunctional RPE cells are often associated with degenerative retinal diseases. The aim o...
