Virus‐specific cytotoxic T cell responses are associated with immunity of the cottontop tamarin to Epstein–Barr virus (EBV)

Cell-mediated immunity: delayed-type hypersensitivity and cytotoxic responses are mediated by different T-cell subclasses

Cell-mediated immunity includes both the generation of cytotoxic cells and initiation of delayed-type hypersensitivity (DTH). The resting T-cell population, before stimulation by antigen, already contains cells of the Lyl subclass that are programmed to initiate DTH (and helper function) but not cytotoxic responses, as well as Ly23 cells which can generate killer activity (and suppressive funct...

Investigating Cytotoxic T cell Responses to RHDV Virus-like particles

Protective Immunity Does Not Correlate with the Hierarchy of  Virus-specific Cytotoxic T Cell Responses to Naturally Processed Peptides

Infection of C57BL/6 mice with lymphocytic choriomeningitis virus (LCMV) stimulates major histocompatibility complex class I-restricted cytotoxic T cells (CTLs), which normally resolve the infection. Three peptide epitopes derived from LCMV have been shown to bind the mouse class I molecule H-2 Db and to stimulate CTL responses in LCMV-infected mice. This report describes the identity and abund...

Characterization of the HCMV-Specific CD4 T Cell Responses that Are Associated with Protective Immunity

Most humans become infected with human cytomegalovirus (HCMV). Typically, the immune system controls the infection, but the virus persists and can reactivate in states of immunodeficiency. While substantial information is available on the contribution of CD8 T cells and antibodies to anti-HCMV immunity, studies of the TH1, TH2, and TH17 subsets have been limited by the low frequency of HCMV-spe...

Immunodominant T-cell responses to dengue virus NS3 are associated with DHF.

Dengue infections are increasing at an alarming rate in many tropical and subtropical countries, where epidemics can put health care systems under extreme pressure. The more severe infections lead to dengue hemorrhagic fever (DHF), which can be life threatening. A variety of viral and host factors have been associated with the severity of dengue infections. Because secondary dengue infection is...
