Increased lymphocyte turnover is a hallmark of pathogenic lentiviral infection. To investigate perturbations in lymphocyte dynamics in natural hosts with nonpathogenic simian immunodeficiency virus (SIV) infection, the nucleoside analog bromodeoxyuridine (BrdU) was administered to six naturally SIV-infected and five SIV-negative sooty mangabeys. As a measure of lymphocyte turnover, we estimated...

CD8(+) cytotoxic T lymphocytes (CTLs) recognize antigen in the context of major histocompatibility complex (MHC) class I molecules. Class I epitopes have been classified as dominant or subdominant depending on the magnitude of the CTL response to the epitope. In this report, we have examined the in vitro memory CTL response of H-2(d) haplotype murine CD8(+) T lymphocytes specific for a dominant...

stem cells from human exfoliated deciduous teeth (shed) have been introduced recently and  possess characteristics similar to  mesenchymal stem  cells (mscs). because of  their convenient accessibility and safety of harvest, shed can be a preferable source for the ever- increasing mscs’ applications. while they are new, their immunoproperties have not been adequately studied. in this study, we ...
