seroprevalence of herpes simplex virus infection in hiv coinfected individuals in eastern india with risk factor analysis.herpes simplex virus type 2 (hsv-2) is the cause of most genital herpes while hsv-1 is responsible for orolabial and facial lesions. in immunocompromised individuals, like hiv patients, impaired immunity leads to more frequent symptomatic and asymptomatic hsv infection. fifty-two blood samples from hiv patients with clinically diagnosed hsv infection were taken as cases, while 45 blood samples each from hiv-infected (hiv control) and noninfected patients without any herpetic lesion (non-hiv cont ...201526557849
herpes simplex virus 1 (hsv-1) and hsv-2 mediate species-specific modulations of programmed necrosis through the viral ribonucleotide reductase large subunit r1.receptor-interacting protein kinase 3 (rip3) and its substrate mixed-lineage kinase domain-like protein (mlkl) are core regulators of programmed necrosis. the elimination of pathogen-infected cells by programmed necrosis acts as an important host defense mechanism. here, we report that human herpes simplex virus 1 (hsv-1) and hsv-2 had opposite impacts on programmed necrosis in human cells versus their impacts in mouse cells. similar to hsv-1, hsv-2 infection triggered programmed necrosis in mou ...201526559832
a herpes simplex virus 2 (hsv-2) gd mutant impaired for neural tropism is superior to an hsv-2 gd subunit vaccine to protect animals from challenge with hsv-2.a recent phase 3 trial with soluble herpes simplex virus 2 (hsv-2) glycoprotein d (gd2t) in adjuvant failed to show protection against genital herpes. we postulated that live attenuated hsv-2 would provide more hsv antigens for induction of virus-specific antibodies and cellular immunity than would gd2t. we previously reported an hsv-2 mutant, hsv2-gd27, in which the nectin-1 binding domain of gd2 is altered so that the virus is impaired for infecting neural cells, but not epithelial cells, in v ...201526559846
current concepts for genital herpes simplex virus infection: diagnostics and pathogenesis of genital tract shedding.herpes simplex virus 2 (hsv-2) is a dna virus that is efficiently transmitted through intimate genital tract contact and causes persistent infection that cannot be eliminated. hsv-2 may cause frequent, symptomatic self-limited genital ulcers, but in most persons infection is subclinical. however, recent studies have demonstrated that the virus is frequently shed from genital surfaces even in the absence of signs or symptoms of clinical disease and that the virus can be transmitted during these p ...201626561565
high rate of β-globin dna detection validates self-sampling in herpes simplex virus shedding studies.self-sampling is a convenient, feasible, and acceptable way of collecting genital specimens, but the veracity of reported self-collection is difficult to verify. we investigated whether a host gene, β-globin, can be used to confirm adequacy of self-collected mucosal and skin genital specimens in studies of genital herpes simplex virus type 2 (hsv-2) infection.201526562701
