Immunization with an inactivated virus is one of the strategies currently being tested towards developing a SARS-CoV-2 vaccine. One methods used to inactivate viruses exposure high doses ionizing radiation damage their nucleic acids. Although gamma-rays effectively induce lesions in RNA, envelope proteins are also highly damaged process. This turn may alter antigenic properties, affecting capac...
Plant RNA viruses have effective strategies to infect host plants through either direct or indirect interactions with various host proteins, thus suppressing the host immune system. When plant RNA viruses enter host cells exposed RNAs of viruses are recognized by the host immune system through processes such as siRNA-dependent silencing. Interestingly, some host RNA binding proteins have been i...
We have isolated and characterized the RNA of intracellular virus nucleocapsids recovered from a number of cell cultures persistently infected with rabies virus or vesicular stomatitis virus (VSV). VSV persistent infections in BHK21, L cells and Aedes albopictus (mosquito) cells generally showed the presence of large amounts of defective-interfering (DI) nucleocapsid RNA and much smaller amount...
OBJECTIVE Zika virus infection during pregnancy is a cause of microcephaly and other fetal brain abnormalities. Reports indicate that the duration of detectable viral RNA in serum after symptom onset is brief. In a recent case report involving a severely affected fetus, Zika virus RNA was detected in maternal serum 10 weeks after symptom onset, longer than the duration of RNA detection in serum...
Potato mop-top virus (PMTV) produces a defective RNA (D RNA) encompassing the 5'-terminal 479 nucleotides (nt) and 3'-terminal 372 nt of RNA-TGB (where TGB is triple gene block). The mechanism that controls D RNA biogenesis and the role of D RNA in virus accumulation was investigated by introducing deletions, insertions, and point mutations into the sequences of the open reading frames (ORFs) o...
The src gene present in all avian sarcoma viruses is not present in the genome of Fujinami sarcoma virus, a potent sarcoma-inducing virus in chickens. Fujinami virus is defective and requires helper virus for replication. RNA from a mixture of helper and transforming viruses consists of two components, 35S and 28S. Oligonucleotide fingerprinting of each RNA component revealed that the 35S compo...
On March 11, 2020, the World Health Organization declared coronavirus disease 2019 (COVID-19) a pandemic; from that date, vaccine race has begun, and many technology platforms to develop specific effective COVID-19 have been launched in several clinical trials (protein subunit, RNA-based, DNA-based, replicating viral vector, nonreplicating inactivated virus, live attenuated virus-like particle)...
