B cell activation by cytomegalovirus
نویسندگان
چکیده
Human cytomegalovirus is shown to be a nonspecific polyclonal B cell activator. The B cell response is independent of virus replication and requires little, if any, T cell help.

Evaluating the Effects of Cytomegalovirus Glycoprotein B on the Maturation and Function of Monocyte-derived dendritic cells
Background & Objectives: Interaction of cytomegalovirus glycoprotein B with toll-like receptors of dendritic cells leads to early signaling and innate immune responses. The aim of this study is to evaluate the effects of cytomegalovirus glycoprotein B on the maturation and function of monocyte-derived dendritic cells in treated groups in comparison with control groups. Materials & Methods: Bloo...
متن کاملB and T Lymphocyte Attenuator is a Target of miR-155 during Naive CD4+ T Cell Activation
Background: MicroRNA-155 (miR-155) is upregulated during T cell activation, but the exact mechanisms by which it influences CD4+ T cell activation remain unclear. Objective: To examine whether the B and T lymphocyte attenuator (BTLA) is a target of miR-155 during naïve CD4+ T cell activation. Methods: Firefly luciferase reporter plasmids pEZX-MT01-wild-type-BTLA and pEZX-MT01-mutant-BTLA were ...

متن کاملNatural Killer Cell Evasion Is Essential for Infection by Rhesus Cytomegalovirus
The natural killer cell receptor NKG2D activates NK cells by engaging one of several ligands (NKG2DLs) belonging to either the MIC or ULBP families. Human cytomegalovirus (HCMV) UL16 and UL142 counteract this activation by retaining NKG2DLs and US18 and US20 act via lysomal degradation but the importance of NK cell evasion for infection is unknown. Since NKG2DLs are highly conserved in rhesus m...
متن کاملGrowth and Isolation of Human Cytomegalovirus on a New Human Fetal Foreskin Fibroblast-derived Cell Line in Iran
Cell culture technique has been used for detection and confirmation of many different viruses in clinical samples. Although, new diagnostic methods have been developed for viral infections, traditional cell culturetechnique is still regarded as the “gold standard” for several infectious agents such as human cytomegalovirus(HCMV). In the present study, a new human fetal foreskin fibr...
