Underestimated effect of intragenic HIV-1 DNA methylation on viral transcription in infected individuals [PDF]

open access: yes, 2020
Background: The HIV-1 proviral genome harbors multiple CpG islands (CpGIs), both in the promoter and intragenic regions. DNA methylation in the promoter region has been shown to be heavily involved in HIV-1 latency regulation in cultured cells.

Severe acute respiratory syndrome coronavirus 2-specific T-cell responses are induced in people living with human immunodeficiency virus after booster vaccination

open access: yesChinese Medical Journal
. Background:. T-cell-mediated immunity is crucial for the effective clearance of viral infection, but the T-cell-mediated immune responses that are induced by booster doses of inactivated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 ...

Sensor Sensibility—HIV-1 and the Innate Immune Response

open access: yesCells, 2020
Innate immunity represents the human immune system’s first line of defense against a pathogenic intruder and is initiated by the recognition of conserved molecular structures known as pathogen-associated molecular patterns (PAMPs) by specialized ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Estimating selection pressures on HIV-1 using phylogenetic likelihood models [PDF]

open access: yes, 2008
Human immunodeficiency virus (HIV-1) can rapidly evolve due to selection pressures exerted by HIV-specific immune responses, antiviral agents, and to allow the virus to establish infection in different compartments in the body. Statistical models applied

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Toll-like receptor gene variants and bacterial vaginosis among HIV-1 infected and uninfected African women. [PDF]

open access: yes, 2015
Bacterial vaginosis (BV) is a common vaginal syndrome associated with altered microflora that increases the risk of preterm delivery and acquisition of sexually transmitted diseases.

HIV-1: maternal prognosis [PDF]

open access: yesRevista do Hospital das Clínicas, 2004
Profound modifications in the profile of patients are currently being observed within the epidemic context of AIDS, especially with respect to pauperization and feminization of the disease. The population most frequently affected is in the reproductive age, and among adults aged 18 to 24 years, the ratio is 1 man to 1 woman, a phenomenon occurring ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...
