The duck plague virus UL7 protein mediates RIG-I degradation to block host antiviral responses and promote viral pathogenesis.

Duck plague (DP), which is caused by duck plague virus (DPV), is an acute, highly contagious disease with an extremely high mortality rate, and poses a serious threat to the waterfowl industry. DPV, which is an immunosuppressive virus, can significantly suppress host innate immune responses during the late stages of infection. However, the specific mechanisms by which the DPV UL7 protein functions in the viral replication cycle and immune evasion remain unclear.

Increased infectivity of human cytomegalovirus strain TB40/E conferred by variants of the envelope glycoprotein UL128 and the regulatory protein IE2.

Human cytomegalovirus (HCMV) infects various cell types in its human host, and this broad tropism plays a vital role in viral transmission, dissemination, and pathogenesis. HCMV strains differ in their ability to infect and replicate in different cell types, but the genetic determinants of cell tropism have only begun to be understood. A widely used HCMV strain, TB40/E, contains a mixture of genetically distinct virus variants.

Effects of different doses of remimazolam besylate on postoperative sedation, pain, and adverse reactions in patients undergoing hysteroscopic surgery.

Background: Hysteroscopy, a minimally invasive gynecological procedure, requires effective sedation for patient comfort and surgical success. Remimazolam Besylate, a new ultra-short-acting benzodiazepine, offers potential for safe sedation, but the optimal dose for postoperative outcomes is unclear. This study evaluated the effects of different doses of Remimazolam Besylate on postoperative sedation, pain, and adverse reactions in hysteroscopic surgery patients.

Unique long 11 and 16 protein act as a bridge for the unique long 11, 16, 21 protein and glycoprotein E interaction in duck plague virus replication.

Unique long (UL) 11, 16, and 21 proteins are duck plague virus (DPV) tegument proteins that are important in virus replication and cell-to-cell spread. gE is an envelope glycoprotein that is critical for DPV virulence. However, information regarding the interactions among DPV viral proteins is limited.

Features and Functions of the Conserved Herpesvirus Tegument Protein UL11 and Its Binding Partners.

The herpesvirus UL11 protein is encoded by the gene and is a membrane-anchored protein with multiple functions. In the last stage of viral replication, UL11 participates in the secondary envelopment process. It also plays a key role in primary envelopment, the transportation of newly assembled viral particles through cytoplasmic vesicles, and virion egress from the cell.

UL11 Protein Is a Key Participant of the Duck Plague Virus in Its Life Cycle.

Tegument protein UL11 plays a critical role in the life cycle of herpesviruses. The UL11 protein of herpesviruses is important for viral particle entry, release, assembly, and secondary envelopment. Lipid raft is cholesterol-rich functional microdomains in cell membranes, which plays an important role in signal transduction and substance transport.

The intracellular domain of duck plague virus glycoprotein E affects UL11 protein incorporation into viral particles.

Studies have shown that proteins in the tegument (located between the viral capsid and envelope layer) play critical roles in the assembly and budding of herpesviruses. The UL11 protein of herpesviruses is important in the process of virus particle cell entry, release, assembly and secondary envelopment. Herpesvirus glycoprotein E (gE) is involved in syncytia formation, transmission between cells and nerve invasion.

Two nuclear localization signals regulate intracellular localization of the duck enteritis virus UL13 protein.

Duck enteritis virus (DEV) multifunctional tegument protein UL13 is predicted to be a conserved herpesvirus protein kinase; however, little is known about its subcellular localization signal. In this study, through transfection of 2 predicted nuclear signals of DEV UL13 fused to enhanced green fluorescent protein, 2 bipartite nuclear localization signals (NLS) were identified. We found that ivermectin blocked the NLS-mediated nuclear import of DEV UL13, showing that the nuclear localization signal of DEV UL13 is a classical importin α- and β-dependent process.

Duck enteritis virus UL21 is a late gene encoding a protein that interacts with pUL16.

Background: pUL21 is a conserved protein of Alphaherpesvirinae that performs multiple important functions. The C-terminus of pUL21 in other members of this subfamily has RNA-binding ability; this domain contributes to pseudorabies virus (PRV) retrograde axonal transport in vitro and in vivo and participates in newly replicated viral DNA packaging and intracellular virus transport. However, knowledge regarding duck enteritis virus (DEV) pUL21 is limited.

Innate Immune Evasion of Alphaherpesvirus Tegument Proteins.

Alphaherpesviruses are a large family of highly successful human and animal DNA viruses that can establish lifelong latent infection in neurons. All alphaherpesviruses have a protein-rich layer called the tegument that, connects the DNA-containing capsid to the envelope. Tegument proteins have a variety of functions, playing roles in viral entry, secondary envelopment, viral capsid nuclear transportation during infection, and immune evasion.

Renal toxic ingredients and their toxicology from traditional Chinese medicine.

Introduction: There have been increasing concerns regarding adverse reactions and toxicity incidents caused by traditional Chinese medicines (TCMs), among which the nephrotoxicity is particularly worrying.

Areas Covered: This review summarizes the ingredients with renal toxicity from some TCMs through searching the relevant literature published over the past two decades. Renal toxicity components from TCMs include aristolochic acids (AAS), alkaloids, anthraquinones and others.
