Heritability of the HIV-1 reservoir size and decay under long-term suppressive ART

Nature Communications, 2020
The HIV reservoir is a major hurdle for a cure of HIV, but the factors determining its size and dynamics remain unclear. Here the authors show in a large cohort of 610 HIV-1 infected individuals, who are on suppressive ART for a median of 5.4 years, that

Peptide‐based antibacterial nanoplatforms: Design principles, stimuli‐regulated behaviors, and applications

Responsive Materials, EarlyView.
Peptide‐based antibacterial nanoplatforms, encompassing self‐assembled peptides and peptide‐engineered inorganic, polymeric, and lipid nanocarriers, are systematically reviewed. The article highlights design principles and stimuli‐responsive regulation for improving peptide stability, delivery efficiency, and antibacterial performance.

The Kidney as a Reservoir for HIV-1 after Renal Transplantation [PDF]

Journal of the American Society of Nephrology, 2014
Since the recent publication of data showing favorable outcomes for patients with HIV-1 and ESRD, kidney transplantation has become a therapeutic option in this population. However, reports have documented unexplained reduced allograft survival in these patients.

Intact proviruses are enriched in the colon and associated with PD-1+TIGIT− mucosal CD4+ T cells of people with HIV-1 on antiretroviral therapyResearch in context

EBioMedicine
Summary: Background: The persistence of intact replication-competent HIV-1 proviruses is responsible for the virological rebound off treatment. The gut could be a major reservoir of HIV-1 due to the high number of infected target cells.

Key Players in HIV-1 Transcriptional Regulation: Targets for a Functional Cure

Viruses, 2020
HIV-1 establishes a life-long infection when proviral DNA integrates into the host genome. The provirus can then either actively transcribe RNA or enter a latent state, without viral production.

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Feasibility of Post‐Operative Telehealth for Pediatric Surgical Patients in Malawi—A Mixed Methods Analysis

World Journal of Surgery, EarlyView.
Pediatric operative volumes in Malawi have increased over the past decade due to an increase in the pediatric surgical workforce and improved infrastructure. Despite growth in surgical capacity, limited data exist regarding post‐operative outcomes for common surgical diseases in low‐resource settings. Post‐operative follow‐up via phone call is feasible

Mycobacterium intracellulare M.i.198—A Promising Strain for Studying Pathogenesis of Nontuberculous Mycobacterial Pulmonary Disease (NTM‐PD)

Microbiology and Immunology, EarlyView.
ABSTRACT In this review, we introduce a promising strain for studying pathogenesis of nontuberculous mycobacterial pulmonary disease (NTM‐PD), Mycobacterium intracellulare M.i.198. M.i.198 was isolated from a patient with progressive Mycobacterium avium‐intracellulare complex pulmonary disease (MAC‐PD) in whom surgical operation was required to ...

HIV-1 Reservoir Association with Immune Activation

EBioMedicine, 2015
In this issue of EBioMedicine, Ruggiero and colleagues describe immune activation biomarkers associated with the size of the HIV reservoir in a carefully designed cross-sectional study. The cohort consists of a homogeneous sample of HIV-1-infected patients with long-term plasma HIV-1 RNA suppression under antiretroviral treatment (ART).

The persistent pool of HIV-1-infected cells is formed episodically during untreated infection

Journal of Virology
Previous studies have shown that the majority of long-lived cells harboring persistent HIV-1 proviral genomes originates from viruses circulating in the year prior to antiretroviral therapy (ART) initiation, but a smaller proportion originates from ...
