Human cytomegalovirus (HCMV) is a risk factor for many human diseases, but among exposed individuals, not everyone is equally likely to develop HCMV-spurred diseases, implying the presence of host genetic factors that might modulate immunity to this virus. Here, we show that antibody responsiveness to HCMV glycoprotein B (gB) is significantly associated(More)
Cytotoxic T lymphocytes (CTL) may undergo massive expansion upon appropriate antigenic stimulation. Homeostasis is maintained by a subsequent "contraction" of these cells. Activation-induced cell death (AICD) and programmed cell death prevent the untoward side effects, arising from excessive numbers and prolonged persistence of activated CTL, that occur(More)
Both genetic and environmental factors are thought to be causal in gliomagenesis. Several genes have been implicated in glioma development, but the putative role of a major immunity-related gene complex member, immunoglobulin heavy chain γ (IGHG) has not been evaluated. Prior observations that IGHG-encoded γ marker (GM) allotypes exhibit differential(More)
Ex vivo-expanded CD8(+) T cells used for adoptive immunotherapy generally acquire an effector memory-like phenotype (TEM cells). With regard to therapeutic applications, two undesired features of this phenotype in vivo are limited persistence and reduced antitumor efficacy, relative to CD8(+) T cells with a central memory-like phenotype (TCM cells).(More)
A protocol for the inducton of somatic embryogenesis from immature zygotic embryos of Rosa bourboniana, a scented rose species, was established. Somatic embryos were induced after 8wk of inoculation of zygotic embryos on MS medium supplemented with different concentrations of 2,4-dichlorophenoxy acetic acid (5–15 μM). In addition to 2,4-dichlorophenoxy(More)
In vitro propagation of rose is an important tool for rapid multiplication and development of new cultivars with desirable traits. However, successful in vitro propagation requires an understanding of specific requirements and precise manipulation of various factors. Efficient protocols for different stages of micropropagation using apical buds or nodal(More)
BACKGROUND Immunoglobulin γ marker (GM) and κ marker (KM) allotypes, hereditary antigenic determinants of γ and κ chains, respectively, have been shown to be associated with immunity to a variety of self and nonself antigens, but their possible contribution to immunity to the tumor-associated antigens epidermal growth factor receptor (EGFR) and EGFR variant(More)
Persistence of effector cytotoxic T lymphocytes (CTLs) during an immunological response is critical for successfully controlling a viral infection or tumor growth. Various cytokines are known to play an important part in regulating the immune response. The IL-2 family of cytokines that includes IL-2 and IL-15 are known to function as growth and survival(More)
Ex vivo–expanded CD8þ T cells used for adoptive immunotherapy generally acquire an effector memorylike phenotype (TEM cells). With regard to therapeutic applications, two undesired features of this phenotype in vivo are limited persistence and reduced antitumor efficacy, relative to CD8þ T cells with a central memory-like phenotype (TCM cells). Furthermore,(More)
T-cell cytolytic activity targeting epidermal melanocytes is shown to cause progressive depigmentation and autoimmune vitiligo. By using the recently developed transgenic mice h3TA2 that carry T cells with a HLA-A2-restricted human tyrosinase peptide (h-Tyr)-reactive TCR and develop spontaneous vitiligo from an early age, we addressed the mechanism(More)
