Production of temperature-sensitive and pathogenic virus from Aedes albopictus cells (Singh) persistently infected with Chikungunya virus

Abstract

When A. albopictus, clone C6/36, cells were infected with chikungunya (CHIK) virus, high virus yield accompanied by a cytopathic effect in the acute stage of infection was followed by a relatively low yield of virus over a long period of time. Virus produced from persistently infected cultures became gradually of smaller plaque size and more temperature-sensitive; however, such virus still retained pathogenicity for suckling mice even after one year of infection. When the persistently infected cells were subcultured, a dissociation was observed between the time course of cell growth and that of virus production, suggesting some intracellular mechanisms that turn off virus production. The greater part of the interference against CHIK virus by the culture medium of the persistently infected cells appeared to be mediated by the infective virus in the medium. The infective virus was easily removed from the persistently infected cells either by subculture or by cloning in the presence of anti-CHIK serum, yielding cured cultures or virus-negative clones.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Systemic juvenile idiopathic arthritis is a rare rheumatic disease that affects children. Symptoms include joint pain, but also fevers and skin rashes. Here is the latest on this disease.

Chromatin Regulation and Circadian Clocks

The circadian clock plays an important role in regulating transcriptional dynamics through changes in chromatin folding and remodelling. Discover the latest research on Chromatin Regulation and Circadian Clocks here.

Central Pontine Myelinolysis

Central Pontine Myelinolysis is a neurologic disorder caused most frequently by rapid correction of hyponatremia and is characterized by demyelination that affects the central portion of the base of the pons. Here is the latest research on this disease.

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

Pontocerebellar Hypoplasia

Pontocerebellar hypoplasias are a group of neurodegenerative autosomal recessive disorders with prenatal onset, atrophy or hypoplasia of the cerebellum, hypoplasia of the ventral pons, microcephaly, variable neocortical atrophy and severe mental and motor impairments. Here is the latest research on pontocerebellar hypoplasia.
