During the recognition task, schizophrenia patients exhibited lower BOLD responses, less accuracy, and longer reaction times to famous and unfamiliar faces. Our results support the hypothesis that impaired face processing in schizophrenia

“Adoptive immunotherapy with donor lymphocyte infusion (DLI) after allogeneic stem cell transplantation (alloSCT) may not only mediate Graft-versus-Leukemia (GvL) reactivity, but also induce Graft-versus-Host Disease (GvHD). As HLA-class II molecules are predominantly expressed on hematopoietic cells, CD4+ T cells may selectively mediate GvL reactivity without GvHD. Here, we assessed the capacity of human CD4+ T cells

to act as sole mediators of GvL reactivity in a NOD/scid mouse model for human acute lymphoblastic leukemia and chronic myeloid leukemia in lymphoid blast crisis. Highly purified CD4+ DLI eradicated the leukemic cells. The anti-tumor immunity was mediated by a polyclonal CD4+ T cell response comprising cytokine-producing T-helper and cytolytic T-effector cells directed against the mismatched HLA-class II molecules of the patients. Furthermore, primary leukemic cells acquired an antigen-presenting cell (APC) phenotype Amino acid in vivo after DLI, as well as in vitro Fedratinib research buy after co-culture with leukemia-specific CD4+ T cells. In conclusion, our results show that CD4+ T cells can be strong

mediators of anti-tumor immunity, and provide evidence that cross-talk between CD4+ T cells and leukemic cells is the basis for induction of leukemic cells with an APC phenotype. These data emphasize the clinical relevance of CD4+ T cell based immunotherapy as treatment modality for hematological malignancies after alloSCT.

“The lateral ventricle in adult mammalian brain is widely acknowledged as one of the areas that undifferentiated neural cells such as neural stem cells and neural progenitor cells inhabit. However, immunological aspects of neural stem cells in the lateral ventricle are still under debate. Here, we report the generation and characterization of a novel monoclonal antibody (mAb), called Namu mAb, which stains the subventricular zone in the lateral ventricle of adult mouse brain. Namu mAb reacted to the cells in the subventricular zone and never reacted to differentiated neural cells such as neurons and glial cells such as astrocytes and oligodendrocytes. Its reaction pattern for the subventricular zone and the neurospheres was similar to that of Nestin and glial fibrillary acidic protein mAbs.
