No evidence for selection of HIV-1 with enhanced gag-protease or Nef function among breakthrough infections in the CAPRISA 004 tenofovir microbicide trial. [PDF]

PLoS ONE, 2013
Use of antiretroviral-based microbicides for HIV-1 prophylaxis could introduce a transmission barrier that inadvertently facilitates the selection of fitter viral variants among incident infections.

Nanoscale Spatial Organization of ARC High‐ and Low‐Order Assemblies at Excitatory Synapses

Advanced Science, EarlyView.
ARC (Activity‐Regulated Cytoskeleton‐Associated protein) mediates synaptic plasticity by forming nanoscale assemblies in neurons. Using super‐resolution microscopy and time‐resolved anisotropy with targeted tagging, the study reveals low‐order ARC assemblies at synapses colocalizing with AMPARs, semi‐circular structures at endocytic zones, and 60–80 nm

Autoprocessing of human immunodeficiency virus type 1 protease miniprecursor fusions in mammalian cells

AIDS Research and Therapy, 2010
Background HIV protease (PR) is a virus-encoded aspartic protease that is essential for viral replication and infectivity. The fully active and mature dimeric protease is released from the Gag-Pol polyprotein as a result of precursor autoprocessing ...

Deep subcutaneous application of poly-L-lactic acid as a filler for facial lipoatrophy in HIV-infected patients [PDF]

, 2005
Introduction: Facial lipoatrophy is a crucial problem of HIV-infected patients undergoing highly active antiretroviral therapy (HAART). Poly-L-lactic acid (PLA), provided as New-Fill(R)/Sculptra(TM), is known as one possible treatment option. In 2004 PLA

Directed Evolution Improves the Catalytic Efficiency of APEX2‐Mediated Proximity‐Dependent RNA Labeling

Advanced Science, EarlyView.
ABSTRACT Engineered ascorbate peroxidase APEX2 has been widely used for spatially restricted profiling of subcellular biomolecules, but its catalytic efficiency toward newly developed probes such as biotin‐aniline (Btn‐An) remains suboptimal. To overcome this limitation, we performed yeast surface display‐based directed evolution to enhance APEX2 ...

Clinical periodontal diagnosis

Periodontology 2000, EarlyView., 2023
Abstract Periodontal diseases include pathological conditions elicited by the presence of bacterial biofilms leading to a host response. In the diagnostic process, clinical signs such as bleeding on probing, development of periodontal pockets and gingival recessions, furcation involvement and presence of radiographic bone loss should be assessed prior ...

Secreted Nonstructural Protein 3 is a Pathogenic Determinant of Orbivirus

Advanced Science, EarlyView.
This study uncovers a conserved PIP2‐dependent secretory pathway of orbivirus NS3 that induces vascular leakage. Pharmacological disruption of PIP2‐NS3 interaction significantly reduces viral pathogenicity and provides protective efficacy in murine models, establishing PIP2‐mediated NS3 secretion as both a key virulence determinant and a promising ...

Proteochemometric modeling of HIV protease susceptibility

BMC Bioinformatics, 2008
Background A major obstacle in treatment of HIV is the ability of the virus to mutate rapidly into drug-resistant variants. A method for predicting the susceptibility of mutated HIV strains to antiviral agents would provide substantial clinical benefit ...
