Heterogeneity of CD4-positive human T-cell clones which recognize the surface protein antigen of Rickettsia typhi.

Immunity to the typhus group of rickettsiae is largely dependent on the effector function of several classes of T lymphocytes, including those which produce gamma interferon. Since the surface protein antigen (SPA) derived from typhus group rickettsiae has been shown to be an effective immunogen in animal models, human T-cell clones specific for the SPA of Rickettsia typhi were isolated and tes...

Surface Proteome Analysis and Characterization of Surface Cell Antigen (Sca) or Autotransporter Family of Rickettsia typhi

Surface proteins of the obligate intracellular bacterium Rickettsia typhi, the agent of murine or endemic typhus fever, comprise an important interface for host-pathogen interactions including adherence, invasion and survival in the host cytoplasm. In this report, we present analyses of the surface exposed proteins of R. typhi based on a suite of predictive algorithms complemented by experiment...

Activation of human T cell clones through the UM4D4/CDw60 surface antigen.

UM4D4 is a recently defined antigen that is expressed on approximately 25% of peripheral blood T cells, but on the majority of T cells in inflammatory synovial fluid. Anti-UM4D4 activates peripheral blood T cells in the presence of accessory cells and/or phorbol ester. UM4D4 has been assigned to a new antigen cluster termed CDw60. The present study examined the ability of anti-UM4D4 to activate...

Producing Soluble Human Programmed Cell Death Protein-1: A Natural supporter for CD4+T cell Cytotoxicity and Tumor Cells Apoptosis

Background: Programmed cell death protein-1 (PD-1)/PD-L1 pathway is one of the immune checkpoint pathways involved in regulation of the immune responses and suppression of anti-tumor defense. PD-1/B7-H1-blocking antibodies improve immune responses such as cytotoxic activity of CD8+/CD4+T cells and also increase mortality of tumor cells; however their use is accompanied by adverse effects in pat...

Recognition of envelope protein by dengue virus serotype-specific human CD4+ CD8- cytotoxic T-cell clones.

We analyzed dengue virus-specific CD4+ CD8- cytotoxic T lymphocytes (CTL) at the clonal level to further understand their role in dengue virus infections. Stimulation of peripheral blood mononuclear cells from two dengue virus type 4 (D4V)-immune donors with live D4V or noninfectious D4V antigen generated 17 HLA class II-restricted CD4+ CTL capable of specific lysis of dengue virus antigen-trea...
