Substitution of gp120 C4 region compensates for V3 loss-of-fitness mutations in HIV-1 CRF01_AE co-receptor switching

Emerging Microbes and Infections, 2023
HIV-1 infection is mediated by a viral envelope subsequently binding to CD4 receptor and two main coreceptors, CCR5 (R5) for primary infection and CXCR4 (X4) in chronic infection.

In Vivo Emergence of HIV-1 Highly Sensitive to Neutralizing Antibodies [PDF]

, 2011
Background: The rapid and continual viral escape from neutralizing antibodies is well documented in HIV-1 infection. Here we report in vivo emergence of viruses with heightened sensitivity to neutralizing antibodies, sometimes paralleling the development

Polyomavirus BK with rearranged noncoding control region emerge in vivo in renal transplant patients and increase viral replication and cytopathology [PDF]

, 2008
Immunosuppression is required for BK viremia and polyomavirus BK-associated nephropathy (PVAN) in kidney transplants (KTs), but the role of viral determinants is unclear.

Viral Tropism and the Pathogenesis of Influenza in the Mammalian Host [PDF]

The American Journal of Pathology, 2007
Influenza viruses, single-stranded negative-sense RNA viruses within the family Orthomyxoviridae, remain an important cause of human morbidity and mortality worldwide. Despite effective vaccines, more than 200,000 individuals in the United States are hospitalized each year for influenza, and approximately 35,000 succumb to disease.1 Seasonal epidemics ...

The Impact of Hepatitis C Virus Entry on Viral Tropism [PDF]

Cell Host & Microbe, 2014
Uptake of hepatitis C virus (HCV) into hepatocytes is an orchestrated process, involving numerous host factors, virion-associated lipoproteins, and a growing number of cell-associated factors. Several of these factors likely contribute to the hepatotropism and limited host range of this virus.

In Vitro and Ex Vivo evidence that pharmacological induction of the hypoxia response pathway efficiently restricts measles and Nipah virus infections

Emerging Microbes and Infections
Airborne RNA viruses of the Paramyxoviridae family are major human pathogens. These include measles virus (MeV) and Nipah virus (NiV), the latter being on the World Health Organization’s blueprint list due to its high case-fatality rate and critical risk

Selective expansion of viral variants following experimental transmission of a reconstituted feline immunodeficiency virus quasispecies [PDF]

, 2013
Following long-term infection with virus derived from the pathogenic GL8 molecular clone of feline immunodeficiency virus (FIV), a range of viral variants emerged with distinct modes of interaction with the viral receptors CD134 and CXCR4, and ...

Arboviruses and Muscle Disorders: From Disease to Cell Biology

Viruses, 2020
Infections due to arboviruses (arthropod-borne viruses) have dramatically increased worldwide during the last few years. In humans, symptoms associated with acute infection of most arboviruses are often described as “dengue-like syndrome”, including ...

Adeno‐associated virus serotype 2 capsid variants for improved liver‐directed gene therapy

Hepatology, EarlyView., 2022
Abstract Background and Aims Current liver‐directed gene therapies look for adeno‐associated virus (AAV) vectors with improved efficacy. With this background, capsid engineering is explored. Whereas shuffled capsid library screenings have resulted in potent liver targeting variants with one first vector in human clinical trials, modifying natural ...

The contribution of viral toxins to infection and pathogenesis

mBio
The process by which viruses cause disease, viral pathogenesis, is the result of both infection of cells and the host immune response. A less studied but equally important contributor to viral pathogenesis is viral dissemination, the capacity of a virus ...
