Selective escape from CD8+ T-Cell responses represents a major driving force of Human Immunodeficiency Virus Type 1 (HIV-1) sequence diversity and reveals constraints on HIV-1 evolution [PDF]

, 2005
The sequence diversity of human immunodeficiency virus type 1 (HIV-1) represents a major obstacle to the development of an effective vaccine, yet the forces impacting the evolution of this pathogen remain unclear.

2b or Not 2b: Experimental Evolution of Functional Exogenous Sequences in a Plant RNA Virus [PDF]

, 2017
International audienceHorizontal gene transfer (HGT) is pervasive in viruses and thought to be a key mechanism in their evolution. On the other hand, strong selective constraints against increasing genome size are an impediment for HGT, rapidly purging ...

Evidence‐Based Clinical Practice Guidelines for the Management of Pediatric Febrile Neutropenia: Resource‐Sensitive Recommendations for the Asian Continent

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Febrile neutropenia (FN) is a frequent and serious complication in children receiving cancer therapy. Standardizing FN management across Asia is challenging due to variable healthcare infrastructure, diagnostic capacity, and infection patterns; however, it could improve resource use and patient outcomes.

SARS-CoV-2 variants: Impact on biological and clinical outcome

Frontiers in Medicine, 2022
The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) that was first identified in December 2019, in Wuhan, China was found to be the etiological agent for a novel respiratory infection that led to a Coronavirus Induced Disease named COVID-19.

Virus evolution: the mutualism-antagonism continuum of virus-virus interactions

Virologie
The conference gathered experts from many fields working on various aspects of virus-virus interactions, ranging from mutualistic to parasitic, and harnessing different approaches to studying virus evolution (e.g., molecular biology, theory, mathematical modelling, genomics, phylogenetics, clinical studies, laboratory experiments).

Antigenic drift in H5N1 avian influenza virus in poultry is driven by mutations in major antigenic sites of the hemagglutinin molecule analogous to those for human influenza virus [PDF]

, 2011
H5N1 highly pathogenic avian influenza virus has been endemic in poultry in Egypt since 2008, notwithstanding the implementation of mass vaccination and culling of infected birds.

Abatacept for Prophylaxis of Acute and Chronic Graft‐Versus‐Host‐Disease in Children Undergoing Allogeneic Hematopoietic Stem Cell Transplantation—A Systematic Review and Meta‐Analysis of Cohort Studies

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Graft‐versus‐host disease (GvHD) remains one of the most significant complications of hematopoietic stem cell transplantation (HSCT). Abatacept, a selective T‐cell costimulation modulator, is a relatively novel prophylactic agent, though pediatric data remain limited.

Detection of genome-scale ordered RNA structure (GORS) in genomes of positive-stranded RNA viruses:Implications for virus evolution and host persistence [PDF]

, 2004
Discrete RNA secondary and higher-order structures, typically local in extent, play a fundamental role in RNA virus replication. Using new bioinformatics analysis methods, we have identified genome-scale ordered RNA structure (GORS) in many genera and ...

Polyomavirus T Antigen Induces APOBEC3B Expression Using an LXCXE-Dependent and TP53-Independent Mechanism

mBio, 2019
APOBEC3B is a single-stranded DNA cytosine deaminase with beneficial innate antiviral functions. However, misregulated APOBEC3B can also be detrimental by inflicting APOBEC signature C-to-T and C-to-G mutations in genomic DNA of multiple cancer types ...

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.
