Background: The effectiveness of T cell vaccination has been demonstrated in a variety of animal models of both induced and spontaneous autoimmune diseases. Objective: The purpose of this study was to test the T cell vaccination protocol to treat and prevent collagen induced arthritis (CIA) in a rheumatoid arthritis model. Methods: CIA was induced by an intradermal injection of an artheritogen ...

T cell responses to myelin basic protein (MBP) are potentially involved in the pathogenesis of multiple sclerosis (MS). Immunization with irradiated MBP-reactive T cells (T cell vaccination) induces anti-idiotypic T cell responses that suppress circulating MBP-reactive T cells. This T cell-T cell interaction is thought to involve the recognition of TCR expressed on target T cells. The study was...

hepatitis b virus (hbv) infection and its sequelae such as cirrhosis and hepatocellular carcinoma has remained a serious public health problem throughout the world. the who strategy for effective control of hbv infection and its complications is mass vaccination of neonates and children within the framework of expanded programme on immunization (epi). vaccination with hepatitis b surface antige...

Patients with rheumatoid arthritis (RA) were treated with a cellular vaccine, which consisted of autologous collagen-reactive T-cells. This study showed that antigen-specific proliferative activity of the peripheral blood mononuclear cells was significantly downregulated after T-cell vaccination in RA patients. T-cell vaccination resulted in a statistically significant decrease in plasma IFNγ l...

Here we review T cell vaccination (TCV), a cell-based, generic approach to immune regulation. We describe TCV clinical trials in multiple sclerosis and other autoimmune diseases; we analyze the immune regulatory mechanisms activated by TCV; we examine the potential of public T cells as TCV mediators, and we discuss the physiology of immune regulation in the light of TCV.

UNLABELLED The possibility that vaccination with adenovirus (AdV) vectors increased mucosal T cell activation remains a central hypothesis to explain the potential enhancement of HIV acquisition within the Step trial. Modeling this within rhesus macaques is complicated because human adenoviruses, including human adenovirus type 5 (HAdV-5), are not endogenous to macaques. Here, we tested whether...

Administration of attenuated pathogenic T cell clones, a procedure known as T cell vaccination, induces CD8+ T cells specific for peptides derived from the Vbeta-chain of the TCR presented by the MHC class Ib molecule, Qa-1 expressed on the vaccine cells. These regulatory CD8+ T cells have the capacity to control the activation of endogenous T cells expressing the same TCR Vbeta-chain as the va...

Immunization with inactivated autoreactive T cells (T cell vaccination) selected from individual's own T cell repertoire provides a unique in vivo setting for testing immune regulation that is known to involve interactions of a variety of related surface molecules (1). It induces regulatory immune responses that closely resemble the in vivo situation where the immune system is challenged by clo...

Despite many efforts to develop AIDS vaccines eliciting virus-specific T-cell responses, whether induction of these memory T cells by vaccination before human immunodeficiency virus (HIV) exposure can actually contribute to effective T-cell responses postinfection remains unclear. In particular, induction of HIV-specific memory CD4(+) T cells may increase the target cell pool for HIV infection ...
