A hot new topic in medical treatment is the use of mesenchymal stem cells (MSC) in therapy. The low frequency of this subpopulation of stem cells in bone marrow (BM) necessitates their in vitro expansion prior to clinical use. We evaluated the effect of long term culture on the senescence of these cells. The mean long term culture was 118 days and the mean(More)
EBV-induced gene 3 (EBI3)-encoded protein can form heterodimers with IL-27P28 and IL-12P35 to form IL-27 and IL-35. IL-27 and IL-35 may influence autoimmunity by inhibiting Th17 differentiation and facilitating the inhibitory roles of Foxp3(+) regulatory T (Treg) cells, respectively. In this study, we have evaluated the development of experimental(More)
One-hundred thirty-two patients with abnormal Papanicolaou smears of the cervix uteri during pregnancy underwent colposcopic evaluation. Seventy-five patients had biopsies during pregnancy, and 34 patients had colposcopic evaluation without performing any biopsy. Postpartum colposcopic evaluation was performed on 95 patients. In 93 patients of this group,(More)
BACKGROUND Mesenchymal stem cells (MSCs) with their potential to differentiate into mesodermal and non-mesodermal lineages have several immunomodulatory characteristics. These properties make them promising tools in cell and gene therapy. OBJECTIVE To evaluate the potential therapeutic applications of autologous MSC in improving clinical manifestations of(More)
In an attempt to evaluate the accuracy of cytologic and colposcopic findings (alone and in combination) in detecting preclinical lesions of the uterine cervix, diagnoses made in 170 consecutive patients referred for colposcopic examination at Nassau Hospital because of an abnormal Papanicolaou smear were reviewed. We found that of the investigative methods(More)
Despite the current limited understanding of the etiology of multiple sclerosis (MS), genetic susceptibility and environmental influences are known driving factors. MS is considered a T-cell-mediated disease given the prevalence of T cells in plaques. Plaque formation is characteristic of this disease attributable to immune mechanisms, triggered by an(More)
IL-27 is a member of the IL-12 family of cytokines that is comprised of an IL-12 p40-related protein subunit, EBV-induced gene 3, and a p35-related subunit, p28. IL-27 functions through IL-27R and has been shown to have potent antitumor activity via activation of a variety of cellular components, including antitumor CD8(+) T-cell responses. However, the(More)
CD200 is a cell-surface glycoprotein that functions through interaction with the CD200 receptor on myeloid lineage cells to regulate myeloid cell functions. Expression of CD200 has been implicated in multiple types of human cancer; however, the impact of tumor expression of CD200 on tumor immunity remains poorly understood. To evaluate this issue, we(More)
CD200 is a cell surface glycoprotein that functions through engaging CD200 receptor on cells of the myeloid lineage and inhibits their functions. Expression of CD200 has been implicated in a variety of human cancer cells including melanoma cells and has been thought to play a protumor role. To investigate the role of cancer cell expression of CD200 in tumor(More)
CD200 is a cell surface glycoprotein that has been implicated in a variety of human cancer cells and has been thought to play a pro-tumor role. However, in our recent study we have revealed that CD200 on cancer cells inhibits tumor formation and metastasis through inhibition of myeloid cells.
