Tumor immunotherapy has had demonstrable efficacy in patients with cancer. The most promising results have been with T-cell–based therapies. These include adoptive cell transfer of tumor-infiltrating lymphocytes, genetically engineered T cells, and immune checkpoint inhibitor antibodies. In this review, we describe the different T-cell–based strategies currently in clinical trials and put their...

Abstract T-cell receptor mimic antibodies (TCRm) have become an attractive therapeutic modality group as they allow for the targeting of intracellular proteins presented by HLA, which may a large potential new targets. However, polymorphic nature classical HLA class I and findings downregulation in cancer cells might limit use these agents treatment. An alternative approach would be to target p...

Organ transplant patients are often treated with immunosuppressants, such as the calcineurin phosphatase inhibitor, cyclosporin A, to block T cell-mediated graft rejection. The calcium release-activated calcium (CRAC/ORAI) channels, which act upstream of calcineurin, are essential for calcium entry and CD4(+) T-cell activation. Although cyclosporine A has also been shown to inhibit FoxP3(+) Tre...

The DNA methylation inhibitor 5-azacytidine induces autoreactivity in cloned CD4+ T cells, but the functional consequences of this response are unknown. We now report that CD4+ T cells treated with 5-azacytidine respond to autologous antigen-presenting cells and induce autologous B cell differentiation without exogenous antigen or mitogen. This mechanism could play a role in some autoimmune dis...

Activation of the transcription factor NF-κB is critical for cytokine production and T cell survival after TCR engagement. The effects of persistent NF-κB activity on T cell function and survival are poorly understood. In this study, using a murine model that expresses a constitutively active form of inhibitor of NF-κB kinase β (caIKKβ) in a T cell-specific manner, we demonstrate that chronic i...

an 11 year – old mixed female labrador was presented with two masses in trunk and neck. the tumoral masses were excised and sent for histopathological and immunohistochemical analyses. histopathological examination of masses revealed diffuse infiltration of small sized lymphoid cells in subcutaneous tissue which were intense around the blood vessels. more than 10% lymphoid cells were cd3 positi...

Rhoads, M. L., Fetterer, R. H., Hill, D. E., and Urban, J. F., Jr. 2000. Trichuris suis: A secretory chymotrypsin/elastase inhibitor with potential as an immunomodulator. Experimental Parasitology 95, 36– 44. A serine protease inhibitor, termed TsCEI, was purified from adultstage Trichuris suis by acid precipitation, affinity chromatography (elastase–agarose), and reverse-phase HPLC. The molecu...

Many tumors, including Hodgkin's lymphoma, are associated with decreased cellular immunity and elevated levels of prostaglandin E(2) (PGE(2)), a known inhibitor of CD4+ T cell activation, suggested to be involved in immune deviation in cancer. To address the molecular mechanisms tumor-derived PGE(2) might have on primary human CD4+ T cells, we used a whole genome-based transcriptional approach ...

Abstract The Provirus Integration sites for Moloney murine leukemia virus (Pim) kinase family has been studied extensively in tumorigenesis. We previously reported a key role of Pim2 negatively regulating T-cell responses to alloantigen. further investigated how regulates mediated anti-tumor using models adoptive cell therapy (ACT) and autologous hematopoietic transplantation (HCT). found that ...
