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.

Prioritization of the Sustainable Development Goals: Developing and Testing a Novel Framework Under Varying Geographic Scales

Sustainable Development, EarlyView.
ABSTRACT This study develops and tests a novel prioritization framework for the Sustainable Development Goals (SDGs) under varying geographic scales (regional, sub‐regional, national), focusing on the Middle East and North Africa (MENA) region as a pilot case.

Hepatitis B Virus RNA Predicts Hepatocellular Carcinoma Despite Viral Suppression

Alimentary Pharmacology &Therapeutics, EarlyView.
Serum HBV RNA levels at viral suppression predict HCC development in nucleos(t)ide analogue‐treated patients with chronic hepatitis B, outperforming Hepatitis B core‐related antigen alone. ABSTRACT Background Despite achieving undetectable hepatitis B virus (HBV) DNA levels with nucleos(t)ide analogue (NA) therapy, patients with chronic hepatitis B ...

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 ...

HIV-1 DNA and the HIV-1 Viral Reservoir

, 2013
HIV-1 infected resting memory CD4+ T cells are major contributors to the HIV-1 viral reservoir, which is established during early infection, maintaining HIV-1 infection for an individual s life. The effect the timing of therapy initiation has on the size and decay of the HIV-1 viral reservoir, the contribution of CD4+ T cell subsets to the viral ...

Behind the scenes: how the EMILIN/Multimerin family shapes the cancer landscape

The FEBS Journal, EarlyView.
The EMILIN/Multimerin family members regulate key hallmarks of cancer—including apoptosis, angiogenesis, metastasis, and tumor microenvironment remodeling. As indicated, their function in immune evasion, drug resistance, and metabolic reprogramming remains largely unexplored.

Detectable HIV-1 in semen in individuals with very low blood viral loads

Virology Journal, 2020
Background Several reports indicate that a portion (5–10%) of men living with HIV-1 intermittently shed HIV-1 RNA into seminal plasma while on long term effective antiretroviral therapy (ART).

Enzymatic synthesis of bioactive quinolones and (thio)coumarins by fungal type III polyketide synthases

The FEBS Journal, EarlyView.
Quinolones are valuable scaffolds for drug discovery but are rare in nature. Here, we show that two fungal enzymes, AthePKS and FerePKS, can generate 2‐quinolones and two additional heteroaromatic scaffolds. Using AthePKS, we designed an artificial enzymatic cascade towards an antimicrobial quinolone from a simple precursor and implemented it in E ...

The forces driving clonal expansion of the HIV-1 latent reservoir

Virology Journal, 2020
Despite antiretroviral therapy (ART) which halts HIV-1 replication and reduces plasma viral load to clinically undetectable levels, viral rebound inevitably occurs once ART is interrupted.

Immune non‐response despite effective antiretroviral therapy in people living with HIV: A review of potential mechanisms, biomarkers and therapeutic approaches

HIV Medicine, EarlyView.
Abstract Introduction A proportion of people living with HIV (PLWH) fail to restore their CD4 count or their CD4/CD8 ratio despite effective antiretroviral therapy (ART). PLWH with immune non‐response (INR) are at a higher risk of both AIDS and non‐AIDS events. The underlying mechanisms of INR remain unclear.
