Herpes Simplex Virus: Infections Associated Systemic Immunocompromise

Infants developing neonatal HSV infections can be classified according to the extent of disease, disseminated or localized. The herpetic zone was surrounded by a brisk proliferation of immunoblasts. 60 to 80% of HSV-seropositive transplant recipients and patients undergoing chemotherapy for hematologic malignancies will experience reactivation of HSV. We found that two dileucine motifs in VP22, at amino acids 235 and 236 and amino acids 251 and 252, were necessary for VP22 regulation of the proper cytoplasmic localization of these viral and cellular proteins.

Replacement of Tyr-371 with phenylalanine (Y371F) in pUL12 (i) abolished its exonuclease activity in HSV-1-infected Vero, HEL, and A549 cells, (ii) reduced viral replication, cell-cell spread, and pUL12 expression in infected cells in a cell type-dependent manner, (iii) led to aberrant subcellular localization of pUL12 in infected cells in a cell type-dependent manner, and (iv) reduced HSV-1 neurovirulence in mice.

In this study we have examined the rapidity with which murine CD8+ memory T cells respond to a localized infection with HSV. We found that infection by an ICP27-null mutant resulted in undetectable UL24 protein expression, which represented at least a 70-fold decrease relative to that of wild-type virus. During the acute phase, HSV-1 was localized to neurons and some small supporting cells in the sensory portion of the 5th cranial nerve including the trigeminal ganglia and nerve root, principal sensory nucleus, mesencephalic nucleus, descending tract and nuclei, and cerebral cortex. We present the case of a patient who developed shingles overlying the incision site of a recently buried central venous access port, illustrating the need to consider this diagnosis as a unique imposter of localized infection or reaction at sites of recent procedural trauma. We report a case of necrotizing HSV lymphadenitis in a patient with both common variable immunodeficiency and natural killer cell deficiency and review the literature on this unusual complication of HSV infection. Some people with aphthous stomatitis may show herpes virus within the epithelium of the mucosa, but without any productive infection. demonstrated that stimulation of peripheral nerves (in rats) can lead to an increase in plasma concentration of ADH.

Results from transfection assays have also indicated that HCF is involved in the nuclear import of VP16. Previous studies have identified the glycoprotein B-derived peptide from residues 498 to 505 (gB498–505) as one of at least three determinants recognized by HSV-1-specific CTLs isolated from C57BL/6 mice. celatum, M. The virus becomes latent in the CNS, then years later, in association with an increase in age and decline in cell mediated immunity, varicella reactivates and herpes zoster, also referred to as shingles, develops. Local trauma has been reported as a precipitant for reactivation, but this condition is rarely seen localized to a fresh surgical incision. Both were euvolemic and had elevated urine osmolality (435 and 368 mmol/kg.H2O) and sodium (Na+) concentration (61 and 63 mmol/L) along with normal cardiac, renal, liver, and endocrine function consistent with the diagnosis of SIADH. This report describes two patients who presented with localized herpetic lymphadenitis documented by light microscopy, immunohistochemistry, and DNA hybridization technics.

This time medication made no difference and it took about 5 weeks to clear up, I got pains in my leg and a few single spots on them, and was tired and flu-like symptoms the whole time. -Primary infection: No presence prior antibodies to HSV 1 or HSV 2. III. This report describes two patients who presented with localized herpetic lymphadenitis documented by light microscopy, immunohistochemistry, and DNA hybridization technics. Infants developing neonatal HSV infections can be classified according to the extent of disease, disseminated or localized. Here, we demonstrate the presence of a second minor population of VP22 in nuclear dots similar in appearance to those formed by VP13/14. The goal of this study was to determine which features of HSV-1 infection function to regulate the translocation of VP22 into the nucleus.

In this report, we show that cellular chaperone proteins, components of the 26S proteasome, and ubiquitin-conjugated proteins are sequestered in discrete foci in the nucleus of the infected cell. We report here that RNA polymerase II is preferentially localized to viral replication compartments early after infection with herpes simplex virus type 1.

The intracellular localization of tankyrase 1 in HSV-1-infected cells (MOI of 1) was analyzed by indirect immunofluorescence using antibodies against tankyrase 1 (N-20) (green) and a marker of the HSV replication compartment (ICP8) (red). CD8(+) T cells did not interact with migratory DCs and their activation was delayed, requiring later clustering interactions with LN-resident XCR1(+) DCs. In immunoblotting experiments, this antiserum recognized a 30-kDa protein in lysates from infected cells. We have identified UL47, a major virion protein, as a novel physiological substrate of Us3.
